Stages of preparing walls for wallpaper and features of the work

Despite the huge selection finishing materials on the shelves construction stores, the most in a known way Indoor wall decoration is wallpapering. They are quite easy to glue with your own hands. There are many types of wallpaper depending on the material from which they were made. Preparing walls for wallpaper is an important stage during renovation.

The walls that will be decorated with wallpaper must be smooth and free of any imperfections. To successfully complete the finishing work, you need to figure out how to prepare the walls for wallpapering.

You should first find out what and how to treat the walls before wallpapering. Step-by-step technology preparation is not only about making the right choice necessary materials, but also in studying all the subtleties. Incorrect repairs can be avoided by carefully reading this material. It is important to take into account all stages of preparation and not skip any of the existing ones.

Why are walls prepared for wallpapering? This is necessary in order to avoid the appearance of fungus and kill existing ones, to ensure good adhesion to the surface. The wall to be pasted must be thoroughly cleaned, it should be leveled as much as possible - then the coating will last longer.

The procedure for preparing walls for wallpaper is as follows:

1. Cleaning old decoration from the surface- any wall decoration must be removed.
2. Primary priming. The surface is treated with the composition after removing all the finishing coating. This is done to disinfect the walls and prevent moisture from being absorbed into them.
3. Sealing cracks and defects. If there are any cracks or holes, they must be repaired. Prepare the gypsum mixture, and then plaster the surface, then putty.
4. Alignment. To do this you will need sandpaper or a special abrasive mesh.
5. Re-treating the walls before wallpapering with a primer mixture. It is carried out with the aim of good adhesion of the wallpaper to the walls, while providing antiseptic and disinfecting effects.

The stages of preparing walls for wallpapering cannot be interchanged. The sequence of work order is very important, because the final result of the work depends on it.

Preparation of materials and tools

Before answering the question of how to properly prepare walls, you need to purchase materials and tools. You will need:

• starting putty or gypsum plaster (levels the surface, applied as the main layer);
• finishing putty(applied to starting putty or directly onto drywall, making the walls perfectly smooth);
• (monitor its application on the previously prepared space).

It is better to use a universal primer, with deep penetration into the surface. Then the preparation of walls for wallpapering will be of the highest quality.

Each purchased material has instructions for preparation and use on its packaging. Please read it before performing any priming work. To prepare the surface for wallpaper, you need to have special tools on hand that will get the job done quickly and efficiently. These materials and tools will simplify the preparation of walls for wallpapering, saving effort and time:

• film (cover the floor);
• stationery knife;
• construction tape (to avoid contamination);
• bucket (mix the mixture);
• roller and brush (coat the surface with primer);
• a pair of spatulas of different sizes (leveling tool);
• drill with a mixer attachment (stir the putty).

Removing old wallpaper from walls

To hang new wallpaper in a room, the old ones must be removed. Without this, it will not be possible to prepare concrete walls for gluing. There are a number of reasons why it is strongly recommended to remove previously pasted wallpaper:

• After a few years, the old wallpaper no longer holds up well. They will become soft and will simply peel off under a slight weight if glue is applied to them for gluing new wallpaper.
• Wallpaper will take a long time to dry if new wallpaper is applied to it.
• After the glued wallpaper dries over the old wallpaper, unevenness appears and the appearance is unsightly.
• The level of adhesion between materials becomes less, which reduces service life.
• Dirt and germs accumulate under the wallpaper over years of service.

When removing old wallpaper, several technologies are used - the initial stages of wall preparation:

1. Manual method. It is used when the wallpaper does not stick well or has come off. Use a spatula to pry from the top and then pull down to clean the coating.
2. Water method. It is used most often. You just need to make scratches in different places on the wallpaper to good penetration water. Next, take hot or warm water (soak a rag and wet the wallpaper). Wait 15 minutes and clean the surface with a spatula or knife.
3. Chemical method. Sold on the construction market chemicals, with the help of which you can easily dismantle wallpaper and not cause damage to the wall, and they do not affect your health. There is only one “but” in this method: it requires additional costs.
4. Steaming. Lightly moisten the wallpaper and blow it with a stream of steam, and then easily remove it.

Wet the wall lightly so as not to damage the surface under the wallpaper. Work in small areas. By the time you reach the middle, the wallpaper will already be dry.

If none of the methods is suitable, you will have to try cleaning with a grinder or drill with an attachment. Only after this will it be possible to putty the surface to level it.

Removing paint

What to do about the problem of painted walls? Removing paint is a very difficult job that takes time. But if the walls are painted, remodelers use three methods to remove the paint:

• mechanical (manual or using electric tools);
• chemical (use chemicals);
• thermal (using high temperature).

Mechanical (manual)- most cheap method and not very dusty. In its implementation, an ax or chisel with a hammer is used. It’s easy to beat the walls with an ax to create cuts, and then spray with water. When it is absorbed, carefully knock off the paint at a convenient angle.

Mechanical (electric tools)– the method involves using a grinder or drill with special attachments. This is much easier than the manual method, but be prepared for a lot of dust.

The chemical method is quite simple. It has only one drawback - you need to spend money to buy the product. In case of application, it is better to wear special clothing for protection, then coat the wall with paint, wait 3-6 hours (depending on the quality of the paint). The paint is softened and brushed off with a wire brush. After this, the wall is washed several times.

Thermal method- This is burning paint with hot air, but this technology is very troublesome. Firstly, you need a special tool (a hair dryer or gas lamp), secondly, burning paint provokes the release of toxic substances that are harmful to health. Thirdly, all the paint is not always burned out.

Primer of walls

How are walls treated before wallpapering? A primer is the product that needs to be used to cover any surface, be it made of drywall, putty or plastered with plaster. Apply the primer mixture to avoid cracks on the surface. It improves the adhesion of the surface to the material, removes unnecessary moisture from it, removes debris and small particles.

How to treat a wall before wallpapering? There are different types of primers:

• acrylic;
• alkyd;
• mineral;
• deep penetration;
• with coloring powders.

How should you treat the walls before wallpapering? This is a personal decision for everyone, but the mixture must be selected taking into account the properties of the surfaces. You can choose the right one with the help of a salesperson in a store or by reading the description on the product.

There is currently a huge selection of primer compositions on the construction market. There are a few basic solutions that are especially highlighted by experts:

• Universal acrylic solution. It is often used due to its ability to be deeply absorbed into the wall, lack of odor, dry in 6 hours and can be used on any wall.
• Contact composition. The most famous solution, used even by beginners. Its properties are exactly the same as those of the acrylic mixture, but in addition it also contains small quartz grains of sand. They increase the penetration of the mixture deep into the surface and at the same time help to level out its minor imperfections.
• Griftal composition. It is used only in places of high humidity, so it is not very well known. Dries within 24 hours after application.

The primer solution is applied to all walls. Use a roller for this, and a brush in the corners. If after priming the wall absorbs everything and becomes dry, you need to apply the primer again.

Leveling the surface

After the walls have dried from the primer, the surface must be leveled (plastered with plaster). Is it necessary to plaster the coating? No, if the walls are dry and smooth, the old plaster does not crumble, and there is not much money in the budget. If the walls are uneven, have many defects and flaws, then they must be plastered for wallpapering. How to level the walls? Using any high-quality gypsum mixture.

All cracks and holes must be filled with the mixture, a layer of maximum 1 cm applied, and the surface leveled with a spatula. Leave the walls until the material is completely dry, then sand with sandpaper or a special mesh.

Let's start puttingty. We spread the putty and use a spatula to level all the surfaces that will be covered with wallpaper. When the procedure is completed, wait for it to dry. The putty surface is sanded until completely smooth. The final stage is re-priming. It must be done before wallpapering, when the walls are already puttied.

Features of concrete surface preparation

Preparing concrete walls for wallpaper is a little difficult because the surface is uneven and dark color that shows through under the light-colored wallpaper. These problems can be solved by puttingtying the surface, but the consumption of the putty mixture will be significant.

Follow these steps to successfully prepare a concrete wall for wallpapering:

1. Choose a finishing material with maximum density - this will help hide the imperfections of concrete. It is better to buy wallpaper in dark colors.
2. Carefully clean concrete walls from dust and dirt.
3. Align all seams of the concrete pavement, putty and sand.
4. Treat with a primer solution or use wallpaper glue. After it dries, you can glue the wallpaper.

Surfaces in panel houses they are simply prepared, but only if they are even. In this case, you don’t have to plaster them, but just coat them with primer, wait for it to dry, and putty right away.

Plaster is put into operation when there are irregularities of more than 1 cm. Leveling must be done before wallpapering the surface.

Rooms in a new building rarely have finishing, so surface treatment before wallpapering will go through all stages. Since the walls are new, they are coated with primer several times, and when installing the plaster, a mesh is used that reinforces the surface and prevents cracks from appearing. Preparing plastered walls will be easier; The main thing is to test it for strength by knocking on it several times. If you hear emptiness, you need to knock down those places and plaster them. After this, the wallpapering procedure will be much easier.

Preparing the walls for wallpaper - not too much simple work, but this can be done with your own efforts. Do you need to hire professionals? You just need to acquire a little knowledge, because preparing walls for wallpapering with your own hands is quite possible.

Primer work and materials used (26 photos)

Having appeared just over a century ago, wallpaper has changed dramatically, thereby changing the technology of pasting. Moreover, all the metamorphoses have occurred mainly over the last 20-30 years - if anyone knows only the old methods and techniques of working with paper trellises, in modern realities will not be able to properly hang wallpaper, since newspapers will no longer help here. New types of trellises require a different approach when preparing walls for their subsequent wallpapering. Why has technology changed so much and how to prepare walls for wallpaper?

The need for preparatory work when covering walls with trellises is due to three factors:

• The use for the construction of new types of wall materials (foam concrete, gas silicate, etc.), which do not hold on their surface without preliminary preparation tapestry fabrics;
• Pasting in some cases a smooth surface on which the glue does not hold the wallpaper well;
• Production of heavy or very thin types of wallpaper. In the first case, problems arise when creating conditions for strong adhesion between the wall surface and the wallpaper; in the second, all the defects of the surface being pasted immediately catch the eye, since modern trellises do not hide them, but stick out.

In this regard, in the process of preparing walls the following tasks must be solved:

• Creating good adhesion between wallpaper glue and wall material. There are two problems here: the porosity of many building materials and smooth surface of concrete, glass, tiles, etc. In the first case, approximately 50% of the wallpaper area is in contact with the wall, which leads to constant peeling of the wallpaper and unraveling of the seams. During the preparatory work, the pores are stopped on the surface wall material a continuous film of primer is created, ensuring ideal adhesion between the wall and the adhesive applied to the trellises. In the second case, it is necessary to create good adhesion of the wallpaper to the wall - the problem can be solved by applying special primers.
• Aligning walls with wallpaper. Modern wallpaper, both thin and dense, does not even hide minor irregularities walls This is especially noticeable when daylight. Therefore, eliminating wall defects is one of the most important tasks during the preparatory work.
• Fighting mold and mildew. This, at first glance, minor task actually helps solve the eternal problem of plaster - the appearance of microorganisms in cracks and crevices in damp rooms and on walls - cold and moisture coming from the street create ideal conditions for the growth and reproduction of mold and various types fungi.

The variety of tasks to be solved when preparing walls for wallpapering breaks the step-by-step instructions for the complete technological process into independent blocks: preparing walls, repairing them and leveling them.

Stages of preparing walls for taping

How to prepare walls for wallpapering? Work on preparing walls for gluing consists of several sequential technological processes.

1. The preparatory stage that completes construction and installation work in a new building. There must be: the work of laying the floor screed has been completed; electrical wiring completed; door (window) frame installed; Built-in furniture is installed.
2. Old wallpaper and paint are removed from the walls, nails and screws are removed.
3. The quality of old plaster is checked by tapping it with a hammer. When dull sounds appear, the wall is cleared of the plaster layer.
4. Chips and peeling are repaired, microcracks are repaired.
5. The walls are washed if necessary (oil stains, soot, dirt are washed off).
6. A primer is applied to create good adhesion between the wall and the plaster layer.
7. Beacons are displayed.
8. The walls are being plastered cement-sand mortar.
9. The applied plaster layer is primed and putty is applied.
10. The final stage of preparation is priming the surface for taping with trellises.

Materials and tools

To carry out the preparatory work, the finisher, regardless of whether he is a beginner or an experienced builder, must have a variety of tools and devices. Their set is dictated by the type of covering to be removed: trellises, paint or plaster; wall type:

• brick;
• concrete;
• wooden;
• plasterboard, etc.

The owner of a house or apartment who carries out repairs on his own needs tools and materials for a specific situation, and therefore there is no need to provide a general list of everything that will be needed during the repair.

To easily navigate necessary materials and instruments, their the list will be given before the description of each type of work. The only thing you should always have at hand is a stepladder or portable platform (horses). Therefore, there will be no further mention of this device.

Preparatory work

Preparing walls for wallpaper will have the following order of work:

• free the walls from old finishing and, if necessary, from plaster;
• repair cracks, chips, jointing masonry joints under plaster;
• level the wall surface with plaster or drywall;
• apply primer under the pasting.

Wall cleaning

Preparing walls for wallpapering with your own hands begins with cleaning the walls of old wallpaper, paint or plaster. Moreover, for each type technological operations there are correct techniques and methods. Let's look at them in more detail.

Wallpaper

How to remove old wallpaper? To do this you need:

1. Clear the walls of furniture - take it into the next room or move it to the center of the room and cover it with polyethylene film.

2. Turn off the electricity in the room being repaired, remove sockets and switches.

3. Collect necessary tools and accessories:

• paint roller (can be used), sponge or rags;
• set of spatulas;
• knife (kitchen or construction);
• bucket for hot water;
• "wallpaper tiger";
• metal brush;
• iron;
• a piece of fabric (old T-shirt, towel);
• garbage bags;
• individual protection means.

4. Buy more if you don’t have a home:

• laundry soap - a quarter of a piece ground into shavings (in a bucket of warm water) will speed up the process of removing wallpaper;
• fabric softener - one cap of the product will give an effect similar to ¼ bar of soap;
• table vinegar (9%) - 5 tbsp. spoons in a bucket of hot water will help you quickly and easily clean the walls of old trellises;
• MK wallpaper glue - diluted to the consistency of kefir (5 times more water than indicated on the package) quickly softens wallpaper, indispensable when removing wallpaper from drywall;
• special compositions - can be bought in liquid or dry form, allow you to remove all types and types of wallpaper from the walls, regardless of the type of glue with which they were glued (see photo).

The methods for removing trellises are influenced, first of all, by the type of glue and the type of wallpaper: paper, non-woven or vinyl. For example, for modified starch (MS) glue, warm or hot water, but for paper wallpaper some methods are used, for non-woven fabric and vinyl - others. If you know the little secrets, the work won't take long.

How to quickly remove old wallpaper from a wall glued with MK glue? For trellises that have been hanging on the wall for more than 8 years, the procedure is very simple. Sections of wallpaper that are lagging behind the wall are cut with a knife. A narrow spatula is inserted into the resulting cracks.

The wallpaper sheet pulls towards itself very slowly - if it moves quickly, the paper will tear due to age. The remaining trellises on the wall are scraped off with a knife or spatula blade. The process can be accelerated if such areas of the wall are moistened with heated water and given time (about 20 minutes) for the paper and glue to soften.

How to remove paper wallpaper from walls when they have been in use for a short period of time? If the trellises have been hanging for less than 4 years, they are wetted warm water. A roller or sponge is suitable for these purposes.

Usually work is carried out not on the entire wall, but on several canvases. After soaking 4-5 wallpaper sheets, they are “forgotten” for 20 minutes. This is enough for the glue (due to the starch it quickly becomes liquid) and the paper to become saturated with water. After that, the wallpaper is removed with a spatula and a knife.

However, this procedure is completely unsuitable for vinyl trellises - the top layer of wallpaper does not allow moisture to pass through. Then how to quickly remove vinyl wallpaper from a wall? There are two ways here.

1. Use a knife to pick up the vinyl layer and tear it off the paper base. Next, proceed in the same way as with paper wallpaper - warm water, a spatula and a knife.
2. Use a knife to make cuts on the trellises (you can use a “wallpaper tiger”) and moisten them. Penetrating under the vinyl film, the water wets the glue and paper, after which the wallpaper easily comes off.

There are some peculiarities when removing paper wallpaper from drywall. Here the soaking process is completely eliminated - water will not only soften the glue and trellises, but also damage the plaster. In this case, liquid wallpaper glue will help.

It is diluted with a large amount of water (4-5 times more than indicated in the instructions) and spread on the trellises. Wetting paper web and the glue used to glue the trellises, such a composition is not able to completely saturate the gypsum board cardboard with water. You can remove the sheets with a spatula and knife after 20-30 minutes. Such methods are not suitable for PVA, MC and CMC glue.

How to quickly remove wallpaper from walls glued with modern high-quality types of glue and PVA glue? PVA glue has the most problems. It must be removed in two stages: first the wallpaper, then the glue itself.

Water-permeable trellises treated with hot soapy water. For this piece laundry soap crushed, diluted in 4 liters of water and brought to a boil and immediately applied with a roller to the wall. After 15-20 minutes, the trellises can be removed without problems.

They do not process the entire wall, but a part. After removing the wet wallpaper, scrape off the remaining adhesive with a spatula or wire brush, the wall is washed out. Then the solution is heated and work continues in the same order.

For water-repellent wallpaper make a solution with fabric softener. For single-layer trellises, 0.3 liters of conditioner per bucket of water is enough; for double-layer trellises, pour twice as much detergent into the water.

The instructions are simple:

1. approximately 2 m2 of wallpaper is wetted;
2. after 10 minutes the next 2 m 2 walls are wetted;
3. after 20 minutes, the wallpaper is removed in the place where the primary soaking was carried out;
4. the remaining glue is scraped off with a wire brush;
5. the next area (2 m2) is soaked, etc.

MC and CMC glue is destroyed either by steaming or when treated with special removers.

Professional builders use a steam generator or steam cleaner, but not every home has one. An iron and a linen towel (any natural fabric without synthetic additives) will come to the rescue.

The technology is as follows:

1. the fabric is lowered into the water, then twisted not very much;
2. the iron warms up to maximum temperature— here you need an extension cord to connect to electricity from another room;
3. the towel is applied to the wallpaper, and, pressing firmly, it is ironed - 5-6 times;
4. The trellises are scraped off from the steamed area with a spatula.

This operation is repeated until the wallpaper is completely removed from the walls. The work is not fast, it takes a lot of time. But in practice it is the best option.

Special washes sold in the form of powder or jelly can speed up the work. Their manufacturers claim that the products are completely safe for the health of people living in the apartment. But, still, it is better to work with gloves.

The solution is prepared in accordance with the recommendation on the packaging. Apply to the wall with a roller. On waterproof trellises, it is necessary to apply perforations with a knife or “wallpaper tiger”. The removers need 2-3 hours to dissolve the adhesive mass, after which the wallpaper will come off the wall on its own.

Liquid and photo wallpapers can be removed by any of the above methods, glass wallpaper- only with washes. When removing glass wallpaper there is little secret: You need to remove one sheet at a time and always pull from top to bottom.

Dye

It is impossible to carry out plastering work on a painted wall to level its surface or apply simple putty - neither cement nor gypsum has adhesion to paint. Therefore it needs to be removed.

Attention: painting the wall is not an obstacle to wallpapering. In many cases, it is possible to glue trellises directly onto the paint layer (see work “”).

To clean the paint layer from the wall you must have:

• personal protective equipment;
• blowtorch;
• grinder;
• axe;
• various attachments for a hammer drill or grinder;
• putty knife;
• chisel;
• paint remover;
• brush.

Using the tools listed above, paint can be removed:

• using chemistry - special solutions (washes);
• heating the surface of the walls - thermal method;
• mechanically - the paint layer is removed with power tools.

Chemical method is based on the ability of special chemical mixtures, for example, “Prestige” gel, “Antikras” remover, etc. to dissolve all types of paints. Wherein:

• the drugs are quite expensive;
• remove only one layer - if you paint multiple times, you will have to dissolve each layer separately;
• a pungent odor lingers in the room for a long time;
• Remnants of flushes should absolutely not be flushed down the toilet - special disposal is required;
• the worker must be dressed in a chemical protection suit;
• upon completion of work, mandatory water procedures.

Conclusion: the method is effective, but has a whole bunch of negative side effects, which is why it is better to abandon it.

The conclusion drawn applies to purchased washes. You can prepare them yourself and not have these problems. Several recipes:

• 0.25 l ammonia(10%) is poured into 1 liter of cold water, 2 kg of construction chalk is added and mixed thoroughly. The resulting mixture is evenly applied to the paint and after 2 hours they begin to remove it (the composition does not destroy the paint layer, but disrupts its adhesion to the wall surface - it is removed in layers);
• Mix 1.2 kg of quicklime and 0.4 kg until thick sour cream soda ash. Apply to the wall and let it soak through the paint. After half a day, the paint layer can be removed;
• Apply a thin layer to the wall liquid glass. After drying, the silicate film is removed, and the paint is removed along with it.

Thermal method based on the ability of the paint to be exposed to high temperatures transition to a semi-amorphous state - when it is no longer solid, but not yet liquid. This layer of paint can be easily removed with a spatula.

You can heat it with a hair dryer, blowtorch, with a simple iron through a newspaper, or even better - food foil. The method has been known for hundreds of years, has been tested and has never failed. The only thing is that you need to be careful when using heat near electrical wiring, switches, sockets and other plastic items - they can ignite or melt.

There is only one downside to this method: when heated oil paint, caustic substances are released into the air.

Mechanical method removing paint from the base was born at the same time as it. The method is labor-intensive, but not harmful to health, does not represent fire danger, allows the use of any available hand-held percussion tools (trowel, axe, chisel, hammer) or power tools with various attachments. Therefore, it can be used to remove paint in the kitchen, nursery and bathroom.

How to remove paint from walls manually? Using a spatula, the paint is removed in places where there are cracks in the paint layer or swelling. Tightly adherent paint can be removed either with a chisel, hammer or axe.

The process can be mechanized and using power tools (drill, hammer drill) with special attachments.

How to repair cracks

After removing the plaster and old finish, the walls are carefully inspected for chips, cracks, damaged masonry joints, etc. Identified defects require elimination, especially cracks.

Cracks in the wall are the scourge of new residents in panel houses. Living-in apartments suffer from this to a much lesser extent - even in old “Khrushchev” apartments you rarely see them. There is a simple explanation - cracks appear mainly due to shrinkage of the building. They must be sealed in any case.

You can repair the crack yourself. For this you will need:

• set of spatulas;
• brush;
• sponge;
• primer;
• sandpaper;
• putty;
• fiberglass mesh (in some cases).

Attention: before starting work to repair a crack, you must make sure that its growth has stopped. Otherwise, all the work will be in vain - you will have to redo it after a certain time.

We will describe the whole process step by step:

1. plaster 2-3 cm wide along the crack;
2. use a spatula to widen the gap; if necessary, you can use other tools (chisel, hatchet, chisel);
3. the edges of the wall near the gap are cleaned with sandpaper;
4. Dirt and dust are removed from the recess and around it (this can be done with a vacuum cleaner or brush);
5. the crack itself and its edges are primed (it is most convenient to perform this operation with a sponge);
6. the gap is sealed with any putty (you can also use acrylic paint sealant);
7. after the repair mixture has dried in the wall gap, a serpyanka (a strip of fiberglass) is applied to the recess and covered with gypsum putty or the same repair compound that was used to seal the crack;
8. Using a wide spatula, level the mixture into a thin layer;
9. the dried solution is sanded manually or with a grinder (sandpaper with a grain of 100-150).

For information: the polymer putty is rubbed into the crack with a narrow spatula, the acrylic sealant is squeezed out from the tube with a pneumatic gun.

Chips and irregularities are initially moistened with “cement laitance” or primer, then sealed with a special solution developed for these purposes.

Potholes in the masonry mortar are deepened by 2.0-2.5 cm, followed by priming and sealing with cement-sand mortar. Cement mixture can be replaced with a very effective polymer-based repair composition. But it all depends on the price of the material - cement-sand mortar is much cheaper.

Before finishing the walls, they must be leveled. Plaster or drywall will come to the rescue. The material “” will tell you what exactly to choose. Let's consider both options.

Leveling by plastering

The most common option for leveling walls is to plaster them with a mortar of cement and sand. In order for the solution to adhere well, the surface under the plaster needs to be primed.

How to prime walls

They begin to plaster the walls after applying a primer to them. This operation allows you to:

• saturate the wall material with moisture, which will not allow it to take water from the plaster mortar;
• create a film with strong adhesion to the wall (the primer penetrates up to 1 cm deep into the material), which in turn provides good adhesion to the plaster;
• increase the strength of the surface of the wall material - the absorbed primer protects the wall from chipping, the formation of small cracks, etc.;
• bind dust particles that actively counteract any connecting processes.

The primer must be selected according to the wall material and type of plaster. For example, primer for concrete and gypsum plaster not suitable for cement-sand plaster mortar.

The repaired wall is being primed paint roller or with a brush in 2 layers. In this case, the next layer must be applied after the first has dried, although there are recommendations to apply the second layer after the first after 10 hours. It is impossible to unequivocally evaluate such advice - there are no studies on this issue.

Plastering a wall

The next stage of preparatory work is the installation of beacons. The operation is described in detail in the work "". Let us briefly recall the entire technological process.

1. In the upper corners of the wall, at a distance of 10-15 cm from the adjacent wall and 20 cm from the ceiling, holes for dowels are drilled with a hammer drill or drill and screws are screwed into them - 2-3 cm of hardware are left above the surface.
2. A plumb line is hung on the head of each self-tapping screw, and a hole is drilled for the second hardware at a height of 20 cm from the floor. After this, the heads of the hardware are brought into one plane (you need to screw in or unscrew one of the screws with a screwdriver).
3. The wall surface is being hung. To do this, a fishing line or twine is stretched between the screws horizontally and diagonally.
4. Using a construction square along a stretched fishing line, measurements are taken of the distance from the surface of the wall to the plane formed by the tensioned fishing lines.
5. Add 3 cm to the point of the wall most curved towards the room and form a new plane - the plane of the plaster.
6. Beacon guides are installed from the PS profile.

The process of plastering with cement-sand mortar is described step by step in the material “”. The stages consist of:

• from spray;
• soil;
• covers.

They are performed in strict sequence after the previous layer has dried.

Splash is produced to create good adhesion of the plaster mortar to the wall. Apply up to 5 mm thick. The solution must be prepared with a high content of binder (cement, gypsum, lime) and be similar in consistency to liquid sour cream.

If a decision has been made not to prime the surface of the walls, then they are moistened with water so that the wall material does not take away some of the moisture from the solution and thereby disturb chemical process formation of cement (gypsum, lime) stone.

Professionals advise starting work from the bottom left corner and going up between the beacon profiles. Having finished the first row, move on to the second, etc.

The second layer, builders call it “primer”, is applied after the spray has completely dried- this is the plaster layer of mortar that levels the wall. Its consistency should resemble bread dough. Thickness - about 2 cm. Work is carried out in the same order as spraying.

Third layer the wall surface is leveled to an almost ideal state. Some specialists are able to perform this part of the operation at such a high level that finishing (finishing) finishing - putty - is not required.

Leveling with plasterboard

How to level walls for wallpaper using “dry plaster”, by which builders mean plasterboard sheets, can be read in the materials “” and “”.

The fastest, easiest and cheapest way to level walls using gypsum plasterboard is to use glue. But this option is only available for small, up to 3-4 cm, height differences on the wall surface. If the curvature is greater, it is imperative to install a sheathing.

If the wall is uneven up to 4 mm, glue is applied to the wall surface and the first sheet of drywall is pressed firmly against it. Subsequent sheets are applied to the wall surface, but are not pressed into the glue. Using a level and a rubber hammer, the gypsum board is brought into the same plane with the already glued sheets (they are tacked to the wall).

If the unevenness is significant, strips of plasterboard come to the rescue, which are glued to the wall, and only then drywall is attached to them. Surprisingly, there are often cases when apartment owners who do the work themselves use a lot of glue instead of strips. The result is the same - when the glue dries, it shrinks strongly and either comes off the gypsum board, or pulls the sheet along with it, causing it to burst.

Primer before wallpaper

Modern wallpapers are made from a variety of materials. It is very difficult to select an adhesive for the combination of wall material and the back side of the trellis. This will require more than a hundred types of adhesive mass.

Manufacturers of wallpaper and glue found a simple way out of this situation: they developed special primers that serve as an intermediate link between wallpaper glue and the material from which the wall is made.

Therefore, you need to choose a primer for wallpaper based on the surface of the wall (it is already adapted to different types of glue). Apply a rough coat of primer with a roller, and in hard-to-reach places with a brush. The second, finishing layer is applied after the first has dried.

For reinforced concrete, the first layer is applied with a diluted primer - it is necessary to saturate it with moisture as much as possible. Re-prime after the already applied primer has completely dried.

Priming walls for wallpaper is discussed in detail in the material ""

The nuances of preparing a wall for different types of wallpaper

Wallpaper can be heavy or light, dense or translucent. This makes some adjustments to the process of preparing walls for taping trellises.

Liquid wallpaper

Liquid wallpaper easily tolerates various uneven surfaces of the walls, but bright spots shine through well and look gray on a dark surface. Therefore, the walls under them do not need to be puttied, but they must be painted with white water-based paint, if they are not light-colored.

Non-woven wallpaper

Lightweight non-woven wallpaper can be glued over old paper trellises and over paint, which simplifies the entire process of preparing walls. The only thing that needs to be controlled is how well the previous finish adheres to the walls, and whether they are translucent bright colors(old wallpaper or wall painting) through the wallpaper. If in one of the cases the condition is not met, then full cycle preparing walls for wallpapering.

Photo wallpaper

The ability of photo wallpaper to emphasize the slightest convexity of the walls while simultaneously distorting the pattern requires mandatory puttying of the surface, followed by sanding by hand or using a sander.

Conclusion

Get a high-quality wall covered without it careful preparation when using modern wallpaper it is problematic. It is necessary to perform a cycle of work:

1. remove old finish;
2. repair walls;
3. level the surface with plaster or sheets of drywall;
4. putty;
5. treat with wallpaper primer.

Some types of wallpaper require additional operations:

• photo wallpaper - sanding putty;
• liquid - painting walls with white water-based paint.

Video on the topic

Before wallpapering walls, you should properly prepare the surface. If concrete walls are smooth, they do not require much effort to process. Minor irregularities can be corrected with putty, and large distortions can be corrected with drywall. It is necessary to become more familiar with the preparation of each of these surfaces.

Required Tools

The tools you need to have are:

• Putty knife.
• Roller.
• Spray.
• Grinder with a metal brush.
• Brush.
• Construction knife.
• Container for mixing putty.

Spray And roller used for removing old wallpaper from walls. The remains of the canvas are cleaned off spatula. The same applies to whitewash, plaster and other materials that are on the surface. The wall must be perfectly clean, free of dust, debris and falling plaster. If the wall was previously painted, then the old coating is removed using grinders with wire brush.

Used for surface treatment with primer roller(preferably with a long handle). With its help you can easily paint the surface under the ceiling. You can apply the liquid with a roller with a short handle or a wide brush. But in order to reach high areas you will need ladder. Brush hard-to-reach places (corners, areas around doors, windows) are treated.

Necessary materials

Materials you will need:

• Primer.
• Putty (to eliminate minor irregularities).
• Plasterboard boards (to eliminate large irregularities).
• Serpyanka.
• PVA glue.

A primer will be required for any type of surface. This material perfectly protects walls from fungus and mold. This is especially true for those walls of the room that are in contact with the street.

If the concrete wall is perfectly flat, then to prepare it it is enough to re-prime it, then you can start gluing it.

The primer must have deep penetration to ensure the strength of the surface layer of the wall and good adhesion of the canvas to it.

But if there are small differences (up to 3 mm), then plaster is used for leveling. Significant differences are eliminated by leveling with plasterboard sheets. After leveling, it is also necessary to treat the wall with a special solution.

Preparing a plastered wall

If minor irregularities have been identified on the walls, then it is best to get rid of them by plastering. To do this, the entire surface of the wall is covered with finishing putty. To eliminate differences of more than 3 mm, a thicker layer of gypsum putty is used, which is applied along the beacons.

After this, the surface is grouted and polished. Such a perfectly flat wall will promote higher adhesion to the wallpaper. But to increase adhesion, several more steps are required:

• Use a brush to remove any remaining dust and debris after sanding. You can also use a vacuum cleaner.
• Moisten a rag with water, twist it well and lightly walk along the wall. Let it dry.
• Carefully inspect the surface for defects.
• Re-prime the wall.

Debris should not remain on the surface, otherwise it may interfere with the quality of adhesion of the canvas to the wall.

If after cleaning small defects are identified, they can be covered with putty. You should not leave an unevenness on the wall with the hope that the wallpaper will disguise it. Under the canvas, this nuance is even more pronounced. After drying the wall, it needs to be re-primed.

If you plan to wallpaper over old putty, then the wall must be inspected as carefully as possible. If the material is held firmly enough and no chips or damage are visible, then you can safely begin cleaning it from dirt and priming it.

But there may be another option - a crack, which is easy to get rid of. To do this, the gap is filled cement mortar or regular tile adhesive. Then left to dry.

If the plaster has crumbled in places, then they need to be cleaned with a wire brush and checked whether the remaining putty is holding well. Additionally, you can tap on the surface to identify those areas of the plastered wall that do not adhere well. The holes are sealed with cement mortar, then covered with finishing putty. After this, the wall is cleaned of dust and primed.

Preparing a plasterboard wall

Significant unevenness in the walls is eliminated by leveling with plasterboard, on which it is planned to glue wallpaper in the future. If there is no curvature of the walls, then there may be another option - installing a plasterboard partition. The first and second cases require proper surface preparation.

To do this, you need to complete several steps:

• Primary surface primer.
• Sealing of seams.
• Putty.
• Secondary primer.

Primary primer is necessary to protect the material from fungus and mold.

In this case, it is necessary to pay special attention to the joints of the material. After this, wait time for drying. Therefore, you can do the work in the evening and proceed to the next stage in the morning.

Then the seams are processed using a special serpyanka tape. It is glued to the joints of the sheets using PVA glue, then covered with putty on top. After the seams have hardened, grouting is done with sandpaper.

You also need to pay attention to drywall screws. Sometimes a small depression forms at the attachment points, which also needs to be covered with putty.

The next stage is complete puttying of the walls. But why putty the entire plasterboard wall if it is already smooth?

Puttying a plasterboard wall is done for the purpose of not tearing off the old wallpaper from the surface along with the top layer of plasterboard during subsequent cosmetic repairs.

Therefore, it is necessary to plaster the wall with a thin layer using a wide spatula, then grout and clean it from dust. Afterwards, secondary priming is performed.

Preparing a concrete wall

Often concrete surface The walls in houses are not ideally smooth. Therefore, complete plastering is used. But if the wall is visually smooth and there are no defects, then complete plastering will not be required. In this case, the surface is inspected for the presence of minor defects: pits, cracks.

Such irregularities are covered with putty. You just need to make sure that no bumps form in the areas where the plaster is applied. Then sanding and dust removal is carried out. After this, priming is performed.

In the video you can see all the stages of preparing the wall surface for wallpapering. Tips and tricks are provided to simplify the process.

Preparing walls for wallpaper with your own hands. Step-by-step instruction

When defects on the surface of a concrete, plaster and plasterboard wall have been eliminated, the priming stage is performed immediately before pasting. Its implementation must be taken with full responsibility, otherwise all the work will go down the drain.

When applying primer to a wall, you must adhere to the following rules:

• Use a large brush.
• Apply in a thick layer.
• When applying, make circular rubbing movements until white foam forms.

The material is applied to the surface with top corner. You need to carefully ensure that all the walls of the room remain covered with primer.

Although the material is transparent, it leaves a wet trail behind which you can navigate. After priming the surface, the room is left for a day to dry. Then you can start wallpapering the walls.

If you do not carry out such preparation, the wallpaper at the joints will begin to diverge or peel off in other places. The surface should be perfectly flat, which will provide better adhesion to the canvas. If the wall remains rough, the wallpaper will stick to it by 50%, which will also lead to further peeling.

• Small irregularities are eliminated with finishing putty. After this, the wall is sanded until smooth. If the surface remains rough, the canvas will hold up worse.
• If after applying the putty, bumps have formed, then they need to be cleaned off with a spatula, otherwise this unevenness will protrude under the wallpaper. And after pasting, these places will be wiped off faster.
• Pay special attention to the corners of the room. They need to be aligned using metal corners, which sit on the putty. Otherwise it can ruin the whole look.

If you plan to level the corners, you must first apply putty to 2 walls opposite each other and let it dry. After this, the adjacent walls and corners are processed. Due to this, the spatula will not leave streaks on the part of the wall that has already dried.

If you plan to paste the walls with light, thin wallpaper on concrete wall, then gaps may be noticeable. Therefore, even if the surface is perfectly flat, it still needs to be applied in a thin layer. finishing putty, then sand and clean from dust.

Proper preparation of walls before wallpapering will ensure high-quality adhesion of the canvas to the wall. Priming prevents moisture from penetrating from adhesive composition into the wall, which will also increase stronger adhesion. You should also remove irregularities, if any, by plastering or leveling with plasterboard.

Many people dreaming of their own home, often fantasize about various topics related to the arrangement of living space.

Some people dream of making a bar counter, others strive to create an elegant wooden interior in an apartment or house using lining and bamboo wallpaper.

Start of renovation in a new apartment, wiring and preparatory work

When purchasing a new home, each person always experiences a large mass positive emotions, but over time people begin to wonder how it is empty room without communications, turn it into a cozy family corner.

The main question that every owner asks himself: “Where to start repairing?”

Indeed, a huge number of cases “pop up” to the surface. In a new apartment, first of all, as a rule, electrical wiring is done.

Installation of electrical wiring on walls

When planning the electrical supply system for your living space, you need to thoroughly study the features of all rooms and schematically outline where the electrical points (sockets and switches) will be located.

It is this action that will determine how the tracing will occur. electric cable, and where the distribution boxes will be located.

Sketch the installation diagram

Each owner, when making repairs in his apartment, must know a number of recommendations and rules during installation, which are regulated by the following publications: “Rules for the installation of electrical installations” (PUE) and “Rules safe operation electrical installations of consumers" (PBEEP).

These are quite voluminous works, which are a postulate for the implementation of various electrical installation work. When organizing electrical wiring in an apartment, it is not necessary to study them completely.

Connect conductors using terminals

The main thing is to comply General requirements and below are the recommendations:

• When installed on a wall, the electrical cable must run strictly along horizontal and vertical lines,
• distribution boxes must be removed from the ceiling at a distance of 20 - 30 cm,
• when measuring and laying a section of an electrical line between a socket or switch and a junction box, it is always necessary to make a reserve of conductors of 20 - 30 cm for convenient connection and installation of elements,
• all electrical components in the apartment should be 10–15 cm away from the corners of the room,
• electrical switches in the room must be installed at a distance of at least 90 cm from the floor,
• when installing sockets on the wall of a room, you need to climb the wall 30 cm or more,
• V distribution boxes It is recommended to connect the conductors using terminal connections.

Some of the above requirements can be visualized in the diagram below.

Do not forget that a well-organized wiring of electrical lines in your living space guarantees the safety of working with various electrical appliances. Many experts recommend using VVG and VVGnG cables for organizing electrical wiring. The thickness of the conductors is selected according to the power consumption of the connected devices.

Preparing the wall surface before finishing

After you have produced electrical wiring indoors, you can begin preparing the interior finishing work, which will be carried out on all planes of the apartment.

Before leveling and tiling the walls new apartment, it is necessary to take care of the evenness of the flooring. Many construction professionals recommend performing this process using self-leveling floors or gypsum-based self-leveling mixtures.

The use of such material makes it possible to create a flat floor in a short period of time on which the finishing coating can be installed.

Leveling the surface

Today, there are two popular ways to level wall bases. This is the performance of work using plaster composition and the method of creating plasterboard covering. Both methods are widely used in finishing work.

Leveling walls using plaster is traditional way creating smooth walls, which has been used for many years.

You can safely install finishing trim on leveled walls.

Before applying a special solution to the walls to level the surface, you need to set guidelines and understand how curved the wall is. The best assistant for solving this problem will be a laser level or rule.

After you have found certain irregularities, you should make corresponding marks on the floor and ceiling. It is according to the created marks that the beacons (landmarks) will be set to create a flat surface.

Having set the guidelines and decided on the layer of plaster coating (2-4 cm), you need to install a special mesh (using mortar or dowels), after which you can throw a leveling compound onto it, evenly distributing it over the surface, relying on the marks (beacons).

Before applying to concrete or brick wall plaster coating, the base should be treated with a high-quality primer. This is necessary to improve the adhesive properties between the wall and the coating.

Installation of plasterboard sheets and organization of finishing wall coverings

The seams are sealed with putty

Repairing premises using gypsum boards is fast, convenient and inexpensive option creating a flat wall and an excellent springboard for the work finishing.

GKL is mounted on a frame made of aluminum profile or wooden blocks. This design is assembled quite quickly and allows you to create separate decorative elements in the apartment, which may even have functional significance (shelves, niches, built-in wardrobes).

Drywall is attached to the frame using self-tapping screws, which are then, like the entire surface of the material, covered with a thin layer of putty, which is a good base for any finishing material, and finishing walls on such a base will not cause much difficulty.

Finish wall covering

Having leveled the walls and prepared the coating for applying the finishing material and various elements decor, you will take a big step, bringing the renovation to its logical conclusion. It is worth choosing one or several types of products with which you will decorate the walls, creating an interior that you will like.

Putty plasterboard and a plastered wall are ideal for finishing with the most popular material - wallpaper.

Today there are many varieties of this product:

Each of listed options has its advantages and disadvantages. IN last years people tend to use natural materials. These include wallpapers made from paper, bamboo and leather.

Bamboo wallpaper - goes well with other decorative elements, made using wooden products (lining, imitation timber). This material is quite difficult to install (after applying the glue it cannot be bent), but it performance characteristics will please any owner.

In addition to wallpaper, wall painting is often used as a finishing touch. Paint is a universal material that goes well with any decorative elements (wallpaper, natural stone, ceramic tiles).

When choosing different finishing materials for one room, you need to imagine how they will combine with each other.

Wall decoration in a new building
Knowing how to decorate walls in a new building will allow you to significantly save on costs and create a pleasant atmosphere in the room.

Non-woven wallpaper is now very often used for finishing walls. This type of finishing material is quite versatile. It is easy to install and operate, waterproof, durable and capable of hiding some small defects on the wall. The choice of non-woven wallpaper can be made for any room.

Using non-woven wallpaper for walls

However, despite the simple requirements for the wall covering on which non-woven wallpaper will be glued, it is still worth preparing it. Today we would like to tell you how to properly work on the walls before wallpapering.

Preparing the walls

Wallpapering is not the most difficult task, especially if it is non-woven wallpaper, but it definitely requires a lot of patience. One of the most important stages work, is precisely the preparation for gluing. Mistakes made at this stage will certainly lead to worse results in the future, therefore it is necessary to adhere to the technology and do everything correctly. Almost any person can cope with this task; it will be enough to gather strength and show some perseverance.

The main thing is not to overdo the dismantling work and stop in time

Removing wallpaper

First of all, we need to dismantle the old wallpaper; for this we will need a sharp spatula and a large amount of water. It is better to choose a small but sharp spatula so that it can easily cut deep into the wallpaper material. We will need a large spatula for the next plastering work.

• If there is old paper wallpaper on the surface of the walls, it will be difficult to remove it, use a large amount of water. Before removing, apply water and let it soak into the wallpaper before removing the old wallpaper.
• If wallpaper on a non-woven basis was previously pasted, then, most likely, it will easily come off in whole sheets. However, in order to pour water behind the wallpaper, it is necessary to damage it, since it itself is waterproof.

To create a smooth and straight wall, after removing the wallpaper, we will need plaster. It is with its help that we will achieve a flat and smooth surface. Most often, wallpaper is torn off the walls along with parts of the plaster, since they were glued tightly.

Not the worst option for dismantling old paintings

Therefore, before gluing new non-woven wallpaper, or canvases on a non-woven basis, we need to create flat surface walls To do this, we use plaster, you can choose the well-known German Rotband, or other options.

Plastering

Wall preparation begins from the very beginning, with careful plastering of the surface. The first layer is applied as a base layer, up to a centimeter or two thick. The consistency of the plaster should be such that it can get into all the recesses of the wall. Irregularities up to a centimeter high are buried in the solution, and the wall becomes smooth.

Before the next layer of putty, called the “finishing” layer, it is necessary to prime the entire surface of the walls. This is done to strengthen the inner layer of plaster. For primer, use a special composition that can be easily found in the store.

The second finishing layer of plaster is applied after the primer has dried; the thickness of this layer varies from 1-3mm. This thin layer of putty removes all minor wall defects. Usually at this stage builders recommend choosing Vetonit, but no matter what finishing putty you choose, the second thin layer will help create a surface close to ideal.

Work on leveling the walls in the room

After the second layer of plaster has dried, the surface is sanded and the remaining minor defects are removed. Now the walls should be white and smooth, it will be easy to glue wallpaper on them on any basis, all that remains is to resolve the issue with the soil.

The plaster walls are behind us, now we have to prime the walls again, but before gluing the non-woven wallpaper. You can prime with wallpaper glue diluted in a more liquid consistency, or use a special composition, which is also sold in concentrate.

This time we are producing a primer to reduce the absorption of the wall surface. We need to ensure that the liquid from the glue is not immediately absorbed and the wall does not remain dry.

Anyone can cope with the task of priming

Now the walls are completely ready for gluing non-woven wallpaper or non-woven fabrics. Let us remind you that glue is not applied to such wallpaper, but only the wall.

Other options

A very bad option if you want to wallpaper a painted wall. Wallpaper does not adhere well to a smooth, slippery surface, so before gluing, we will have to remove a layer of paint from the walls.

This is a very labor-intensive task, but if we want to make a full-fledged repair, we will have to sacrifice time. All basic preparation for working with wallpaper will consist of removing paint from all walls in the room.

The paint on the walls varies

We can remove paint from the wall in several ways:

• The simplest and lowest-quality option is to sand the surface of the walls, and in some places, use a knife to make notches and nicks. Then a primer is applied and the wallpaper is glued, but it will not stick well everywhere.
• Another option is not the safest - the paint is removed from the walls with a spatula, for which it is heated using a hair dryer. This must be done in a respirator and with good air circulation, since when heated, harmful substances can be released from the paint.
• The third option is very dusty and dirty - the paint is removed using a brush or an iron brush placed on a hammer drill or grinder. When sanding walls, a huge amount of dust is released, so the room needs to be insulated as much as possible: close all doors, windows and plug up the cracks.
• The last option is to use special solutions to remove paint and varnish. This method is also quite dangerous, so take care of personal protective equipment.

After removing paint from the wall, before gluing non-woven wallpaper, the walls must be primed, since in their original form they absorb liquids very strongly. The concrete-contact primer copes well with this task.

This time, the dusty method was chosen to remove paint from the walls.

If the walls were badly damaged when the paintwork was removed, then we return to plastering the walls. If there is extremely large damage, it is even possible to plaster the walls using beacons. However, this method involves applying large quantity plastering material.

Often there are walls that require a huge amount of plaster to level them. In this case, it is permissible to consider leveling the geometry of the room using drywall. Irregularities and defects in the walls are simply covered with gypsum boards.

Using plasterboard for finishing walls

Non-woven wallpaper adheres simply perfectly to plasterboard walls, but it also needs to be primed, but in this case you won’t need much primer material. Vinyl wallpapers on a non-woven base will fit perfectly on smooth, prepared plasterboard walls.

Properly preparing your walls before you hang your wallpaper will avoid many problems in the future. Even if the repairs are carried out by amateurs, many difficulties in the work can be avoided by carrying out basic work on leveling the walls. In the future, all you have to do is enjoy the excellent renovation.

Preparing walls for wallpapering - step-by-step instructions

Often people try to decorate their home on their own, which results in pretty good results. Preparing the walls requires a careful approach to wallpapering. It will help in this matter step-by-step instruction. It is important to take the procedure seriously so that problems do not arise in the future.

Preparing walls for wallpapering

1. Often in multi-storey buildings the walls have a far from ideal surface. Therefore, the preparation of walls for wallpapering must be done properly. In order for the result to please you in the end, you need to get rid of all the flaws and imperfections that interfere with high-quality repairs.

2. It is important to completely dismantle all the old coating. Do not give in to the temptation to glue new wallpaper onto a supposedly strong base of several layers. It is a mistake to believe that this will make your work easier. In any case, swellings could have formed under the old sheets in some places.

3. Such little things lead to the waste of gluing a new coating. In areas of swelling, the sheets simply begin to lag behind the walls. Also, such little things have a negative impact on the appearance of the room. Preparing walls for wallpaper is an important component quality repairs with your own hands. It is during dismantling that all the flaws that need to be eliminated are revealed.

4. Preparing walls for wallpapering after dismantling begins with puttying. This is the step-by-step instructions. The surface must be brought to an ideal state using a special solution. As a result, the canvas will lie much better and smoother. It is also worth considering that light sheets will show through on a dark, spotted wall.

5. Therefore, preparing walls for wallpaper implies a unique order of work. Dark walls should always be lightened, despite the fact that they may be quite smooth. After puttying, you need to proceed to the next step. This will require a primer. After treating the walls with it, the adhesion of the paintings to the surface will increase.

6. In addition to the fact that the wallpaper will adhere better to the ground, the directional composition perfectly protects the walls from mold. A more professional primer is able to level out some uneven areas and holes. To do this, you need to resort to using a special thick primer. Therefore, during the general preparation of the walls, remove everything unnecessary that may interfere.

Treating walls before wallpapering

1. Regardless of the type of surface, it must be treated with putty and primer. After dismantling and fixing some problems and little things, proceed further. In any case, the coating must be treated with putty. If the wall is smooth, apply a thin layer.

2. Using putty, you will give the wall a uniform tone that will not show through the canvas. It is also worth paying special attention to the type of putty. The material should stick easily in the future. That’s why preparing walls for wallpapering is so important.

3. Step-by-step instructions help you avoid common mistakes. Often an acrylic mixture is used as a universal composition. This putty is considered unpretentious and suitable for any purpose. Wallpaper on such a surface lasts quite well and for a long time. Also, in the future you will not need to bother with major repairs.

4. It’s clear how to prepare walls for wallpapering using putty, now let’s move on to the next step. It is important to treat the surface with your own hands using soil. As mentioned earlier, it provides better grip on the walls with the sheets. The soil also protects walls and wallpaper from fungus.

5. As with putty, the primer should be selected based on acrylic. This composition has a lot of advantages, and it is odorless. The product dries quickly enough, the procedure takes 4-5 hours. Keep in mind that such soil is not suitable for metal elements; corrosion occurs.

6. If you decide to coat wooden surface elements, you should give preference to an alkyd primer. Acrylic mixture is also not bad, but alkyd is more suitable for natural material. Keep in mind that the alkyd base can take up to 14-16 hours to dry. Often, not many homeowners know how to properly prepare walls. Therefore, it is worth approaching the process responsibly and studying the materials market.

Preparing plasterboard walls for wallpapering

1. Do not assume in vain that preparation plasterboard walls wallpapering makes the task much easier. Step-by-step instructions are also important in this matter.

2. Such panels must be coated with a composition directed against the formation of various fungi.

3. Drywall requires special attention, so finishing the walls with wallpaper will be quite difficult. By using special device in the form of a sickle mesh and putty, it is necessary to seal all the joints and seams between the drywall panels.

4. This procedure is carried out without fail, so that during subsequent wallpapering the walls do not become deformed. Next, the plasterboard sheets are treated with an acrylic-based primer. Wait for the composition to dry and you can proceed to the final stage.

Preparing walls for liquid wallpaper

1. This question has a number of peculiarities. Wallpaper in liquid form is distributed over the wall along with all the dirt that is present on the surface. As a result, some unevenness and stains remain. Appearance the premises are deteriorating.

2. Preparing walls for liquid wallpaper requires special patience and accuracy. Therefore, in order not to encounter the problems described above, you need to do everything possible with your own hands. Carefully walk around the perimeter and get rid of any dirt on the walls.

3. If you are faced with the fact that the walls are concrete or plastered and at the same time have fairly wide pores and minor irregularities, you need to eliminate this. Take advantage gypsum putty, then apply 2 coats of primer.

4. Wait for it to dry, evaluate the surrounding environment to see if there are any defects in the form of pores or irregularities. If everything is in order, treat the walls with a white base for liquid wallpaper. This move will help to avoid showing through flaws that you did not notice. After the base has dried, liquid wallpaper is applied.

Preparing walls for wallpapering requires patience and some skill. Step-by-step instructions will help you avoid common mistakes. Don't rush anywhere and do everything conscientiously. There is nothing complicated about the repair. The main thing is to take into account all the little things, so as not to redo it again later. Happy renovation!

Wallpaper is the most popular type of finishing materials. A huge variety of colors and patterns, a wide range of prices make the described material the most popular in the construction market.
But you need to know how to properly prepare walls for wallpapering, so that the most expensive wallpaper looks beautiful on the walls if it is properly prepared for wallpapering.
Let's say right away that preparing the surface for wallpapering is not difficult, but it requires certain knowledge, skills and special tools. A beginner can easily cope with this task if he carefully reads the proposed article.

Where to start repairs

Any work begins with the preparation process. You need to purchase the material itself and related products, tools and accessories.

We have talked about this more than once on the pages of our website.

Tools you will need:

• a mandrel for fastening the abrasive or a grinding block;
• abrasive material;
• sanding sponges for processing hard-to-reach places.

You can use a sanding mesh as an abrasive material, but it is cheaper to use sandpaper. The quality of work will not suffer from this.
The use of a sanding mesh makes work more comfortable, since the mesh does not become clogged with debris and dust during work. But the right paper also gives very good results. In addition, it is much cheaper than mesh.

The abrasive material is marked on back side. Numbers 80...200 characterize the coarse-grained structure of the abrasive, and numbers 250...2500 indicate the fine-grained structure of the sanding material.

Sanding sponges are available with cut corners for easy processing of hard-to-reach areas.

From the devices you will need:

• stepladder or sturdy table;
• spotlight or lighting device;
• spatulas;
• rule or level.

Always remember safety precautions

Any work should bring joy and not have a harmful effect on human health. Preparing walls for wallpapering is a dirty, dusty process.
You cannot do without safety glasses, a respirator or gauze bandage, and a headgear.

Removing old coating
If you are going to glue wallpaper in a new room, then brick surface It will be necessary to sand and prime.
The plasterboard surface also requires priming.

A more labor-intensive process awaits you if you are going to re-glue the wallpaper or stick it on a painted or wooden surface.

You will need to prepare the surface by clearing it of old wallpaper, paint and nails. Wooden wall will have to be plastered or sheathed with plasterboard.

First things first
Any surface is freed from the old coating, dried and primed. If the surface is very uneven, it is plastered.
After drying for 24 hours, the surface is primed again. The primer is applied after each layer of plaster or putty.

Rule 1
To obtain a high-quality surface, the service life of which can be measured in tens of years, be sure to use all Consumables one manufacturer.

If you bought plaster from a certain manufacturer, then the putty and primer should preferably be from that manufacturer.

Once again about removing old wallpaper

You can use different methods to remove old wallpaper.
The simplest and most reliable method is to moisten the surface with a warm cleaning solution. The solution is applied to paper wallpaper using a sponge, roller, or sprayer. After a pause of 15 minutes, you can carefully remove loose and swollen wallpaper with a spatula.
This method is good for removing thin paper wallpaper.

Do not forget that multi-layer wallpaper cannot be removed this way. They are removed by using a steam generator or ironing them with a hot iron through a damp cloth.
Multilayer wallpapers include non-woven, vinyl, and washable wallpapers, since they have a top protective layer that prevents water from reaching the surface.

About the most important thing

To obtain a high-quality surface for wallpapering, it is necessary to perform final sanding.
To prepare walls for wallpapering, follow the basic steps:

1. Install proper side lighting. The light source must remain in one place throughout the entire work.
2. Grind the walls from top to bottom using circular movements of the tool.
3. Treat strips no wider than 1 meter. Once the strip goes all the way to the bottom, sand the next strip the same width.
4. Check the surface for clearance using a level or rule applied to the surface being treated.

Never attempt to sand down pits or depressions. You will only ruin the surface. It is better to putty the identified defect. Followed by surface cleaning

When preparing walls for wallpaper, minor scratches are allowed on the polished surface.

A few words about mechanization of the process

The use of mechanical devices is advisable for plastering, rough grinding.
