Liquid wallpaper for the ceiling is one of the most economical options finishing. Unlike other more expensive types, liquid wallpaper can be hung with your own hands without the involvement of specialists. In addition, they hide minor ceiling defects. How to glue them correctly and what are their pros and cons? This is exactly what we will look at in the article below.

Liquid wallpaper is not yet so widespread due to its relatively recent appearance on the market. Although they are called wallpaper, this is not an entirely accurate name. This is not the usual roll, but rather plaster. Those who have not encountered this type doubt the possibility of applying the material to the ceiling. And in vain - liquid wallpaper will become an excellent covering for the ceiling. They have warmth and soundproofing properties, which is very important in modern buildings.

One of the main advantages of this type ceiling decoration- safety. Liquid wallpaper is made from natural materials: cotton, silk and cellulose. They do not emit any toxic substances. They can be used in a children's room without fear for the child's health. If you have allergies in your home, then liquid wallpaper will not cause discomfort, since dust does not collect on it, due to the presence of antistatic substances in its composition.

With help liquid wallpaper You can create any drawing and design. You won’t have to spend much on wallpaper, since they are budget coatings. In addition, they do not require an additional layer of putty in the presence of small cracks.

If you have large holes in the ceiling, you won’t be able to get past the putty. To obtain a more saturated color, the ceilings are pre-coated with white water-based paint.

They can be painted at any time. This will appeal to those who often change some interior details. The technique of applying the material is no different from putty; this will save you from the labor-intensive work that is necessary when gluing roll wallpaper. In addition, the adhesion of liquid wallpaper is much higher.

The mixture can be removed and applied several times. If you have damage to a specific area, there is no need to replace the entire coating, just remove the old wallpaper with water and then apply new wallpaper.

Such wallpaper is a reusable material: they can be removed, stored, and then reapplied in any room. Do not throw away the remaining mixture, leave it. It will dry and then it can be used again, for example, to repair damage.

They are sold in powder form, to which you just need to add water for application. Some manufacturers produce raw materials without adding dye and glue, then you will have to add it all yourself. This is easy to do if you follow the instructions on the box. Colorless the material is suitable for those who don’t like the available colors, just buy the color and add in the right amount for the required color saturation.

Caring for the material is easy, the wallpaper is not afraid wet cleaning. Liquid wallpaper will look good on any surface; it easily comes into contact with other types of materials. After drying, they do not leave seams, so they can be used to finish complex structures, for example, made of plasterboard.

Their service life reaches 20 years. They are not afraid of the sun and high temperatures.

Disadvantages include their sensitivity to water. If it gets in large quantities, they again become a liquid mixture that comes off the ceiling. If you want to use them in the kitchen, you need to apply an additional layer of varnish.

Types of liquid wallpaper

Liquid wallpaper is divided into three types according to its composition:

• Cellulose. The cheapest and therefore do not have high performance. One of the disadvantages is that they burn out. Therefore, they are best used in rooms without windows or with little incoming sunlight.
• Silk. The most expensive due to the silk it contains. Such wallpapers do not fade or fade. Their service life is very long, and they will not be deformed.
• Silk-cellulose. They combine the qualities of both types. They are not afraid of the sun, they will not last as long as silk ones, but for sure 10 years.

Required Tools

Before you start working with the surface, you need to prepare everything you need.

1. Container for composition. The powder will swell, so a small container will not work.
2. Putty knife.
3. Roller.
4. Spray.
5. Drill.
6. Plastic grater

Preparing the ceiling for liquid wallpaper

Finishing the ceiling with liquid wallpaper is impossible without preliminary preparation surfaces. Remove all old coating: whitewash, old wallpaper, all roughness. If your ceiling was previously painted with water-based paint, then it is not necessary to remove it. Look at the condition.

If it does not peel off, there are no tubercles, then liquid wallpaper can be glued to it.

If there is fungus or mold on the ceiling, they must be removed and the ceiling treated with an antifungal compound in several layers. Even if there is no mold, a layer of primer must be applied. Or better yet, two. If the base of the ceiling absorbs well, then so do all three layers.

Fill large cracks with putty to level the surface. To do this, check the ceiling using a level. Remove all irregularities. If you do not have large cracks in the ceiling, then it is not necessary to repair small ones. The wallpaper itself can handle them.

If you have a dark ceiling, then you can use white water-based paint as the second layer rather than a primer. Or use primer paint. This is a special paint with primer properties.

If you plan to create a drawing from liquid wallpaper, then the preparatory work will include one more item: draw a sketch of the future drawing on paper. Then the ceiling is measured and a design marking is applied to it. It can be applied not only by hand; there are special stencils in stores, which greatly simplifies the process.

How to apply liquid wallpaper to the ceiling

Stores sell ready-made formulations for application. Diluted in buckets. There is no need to add anything to this mixture; you can apply it immediately. And there are dry mixtures that you need to prepare yourself. Choose better than the second one option, then you can choose the color yourself, adding it to the desired shade. Filler to create texture is also added separately.

To dilute the composition, pour the powder into large capacity and add water, stirring constantly, add powder. Then, stirring, add dye and decorative elements. You can knead the wallpaper with your hands like dough, or you can use a construction mixer. The color is added in accordance with the table on the packaging. Don't pour hot water. This reduces the adhesion of the composition. The water should be slightly warm to make it comfortable to work with. Waiting for the mixture to infuse can take from 15 minutes to 15 hours. Will have to wait.

There are two application methods: mechanical and manual.

How to properly apply wallpaper by hand. Wallpaper is applied with a roller or spatula. To work, you will need a stepladder or, in extreme cases, a chair. You should be able to see the surface very well for an even application. The work must be done immediately. There is no need to leave the piece for the next day: stripes will be visible, as when painting. Having processed specific area, inspect it for any defects.

The application layer should be 1-4 mm. The mixture is leveled with a smooth grater, while using hand movements you shape the position of the fibers. How you arrange them will depend decorative effect. After applying the mixture, you need to give 1 day for complete fixation. If there is a need to ensure moisture resistance, coat the ceiling with several layers of varnish.

When applied mechanically a spray bottle is used. A thin layer of the mixture is applied to the ceiling, and after drying, the procedure is repeated to add thickness.

How to make a drawing. Liquid wallpaper allows you to create any pattern. There are no restrictions. However, this will take much longer than just coating. The fact is that when applying a pattern you have to wait until each individual layer dries. There are two types of application: handmade and on a stencil. Various stencils can be bought at any hardware store.

To begin with, the surface is completely covered with the base layer. After drying with masking tape The stencil is fixed and the design is applied to it.

At manual way on the ceiling with a simple pencil draw a sketch of the drawing. Apply a layer of wallpaper 1.5 mm thick, extending beyond the contours. Using a spatula, carefully move the material back, this will be the border. Wait until the material dries. Step back from the dry area and apply the next layer, moving it towards the already dry one, but make sure that they do not mix.

To apply the design, it is best to use a silk-based composition.

This universal material used for finishing wall and ceiling surfaces indoors. Its advantage is that it combines well with other types of finishes. The coating can be applied to any surface, even curved. As a result, you will get a seamless and uniform coating. We will tell you how to apply liquid wallpaper to the ceiling, what types of this material exist, and how to properly prepare the surface for application.

Types of liquid wallpaper

Liquid wallpaper is a mixture of additives, textile fibers and cellulose. They are sold as a ready-to-use liquid mixture or as a dry formulation that is mixed with water before use. Since the technology of their application is similar to plaster, the material is called silk plaster.

Liquid wallpaper for the ceiling comes in several types:

• by surface type they are divided into embossed and smooth (it all depends on the size of the fibers used);
• The color of the material can be white or colored (if necessary, the white mass is tinted to obtain the required shade);
• the mixture can be homogeneous or with special additives to obtain a certain texture;
• Based on their composition, wallpapers are divided into cellulose products, cotton coverings, mixed and silk compositions.

Depending on the size of the fibers, liquid wallpaper on the ceiling has some texture. The larger the fibers, the rougher the surface. In addition, a special application technique is used to obtain relief. To do this, run a texture roller over the damp surface of the wallpaper. As a result, a relief pattern remains on the coating.

Thanks to the large assortment of colors, choosing a coating to match the color of the entire interior is easy. If you can't choose desired color ceiling, then the white composition is tinted with water-soluble pigments. Finishing the ceiling with liquid wallpaper can have a certain effect depending on the additives used.
The following components are commonly used:

• cotton or silk threads;
• metallic sparkles;
• stone chips;
• cellulose fibers of different sizes.

Important! The appearance of the coating largely depends on the material that serves as the basis of the wallpaper. The characteristics, price and durability of the product depend on this.

Pulp

This is a budget type of coverage. Cheap raw materials are used:

• cellulose fibers;
• plasticizers;
• dyes;
• adhesive components;
• sometimes additives.

Features of cellulose products:

• good adhesion to the surface due to the presence of cellulose, which provides better adhesion;
• Wallpaper fades quickly, so it is better to use it in the corridor where the sun's rays do not penetrate.

Cotton

This liquid ceiling has a matte shine and soft structure. This is achieved due to the presence of cotton fibers in the composition. The coating has high sound and heat insulation characteristics. This environmentally friendly coating is often used in the bedroom and children's room.

Silk

The most expensive repairs are performed using silk wallpaper. The material contains natural silk fibers.

The advantages of finishing the ceiling with liquid wallpaper:

• attractive appearance;
• durability of the coating;
• material strength;
• the surface has a beautiful characteristic shine;
• resistance to fading (the coating is allowed to be used in rooms with panoramic windows);
• thanks to additives, they achieve the effect of textile finishing or an exact imitation of marble.

Mixed

Repairing ceilings with liquid wallpaper of a mixed composition has its advantages. Since the material uses fabric and cellulose fibers, it is possible to obtain a beautiful coating for little money. The cost of a mixed product depends on the percentage of cotton and silk fibers, as well as the presence of decorative additives.

Advice! If you want to get wallpaper with a decorative effect, you can add metallic glitter, mineral additives and other components yourself.

Advantages and disadvantages of liquid wallpaper

Pasting liquid wallpaper on the ceiling provides the following advantages:

1. This environmentally friendly and harmless coating does not interfere with the surface underneath to carry out air exchange, absorb and release moisture.
2. You get a seamless, uniform finish that hides substrate imperfections well.
3. The surface for gluing liquid wallpaper does not require complex preparation.
4. The coating lays flat on the base of any configuration, without creases or folds.
5. By adding pigments and additional components, you can obtain a material with different effects.
6. There are wallpapers with smooth or embossed texture.
7. Opportunity local repairs. Only the damaged area is redone; there is no need to remove and re-glue the entire coating.

The disadvantages of this material include the following:

1. Compared to ordinary wallpaper, this is a very expensive finish, because the price can be five times higher.
2. The coating is not resistant to moisture, so it comes off easily after getting wet.
3. Cellulose wallpaper loses its attractiveness over time because it fades.
4. Their installation requires certain skills.

Some material shortcomings are easy to compensate for. For example, to increase the moisture resistance of a surface, it is coated with acrylic varnish. Coverings that contain at least 40 percent cotton and silk fibers will last longer.

Technology of applying liquid wallpaper to the ceiling

Finishing the ceiling with liquid wallpaper with your own hands is carried out in two stages:

• first prepare the base surface;
• then apply the prepared composition.

Important! The durability of the coating and its adhesion to the base surface depend on the quality of preparation of the base.

Preparing the ceiling surface

The easiest way to prepare the ceiling in a new building is with a rough coating. It is enough to prime the surface.
If there is an old coating on the ceiling, then the preparatory work is as follows:

1. Old wallpaper is moistened and removed with a spatula. Whitewash or interior paint must be cleaned off. Depending on the composition used, special washes or ordinary water are used. Enamels and acrylic paints clean with a grinder or spatula.
2. Stains from rust, mold and water must be washed off. To do this, use a weak solution of orthophosphoric or of hydrochloric acid. Used to remove grease stains alkaline solutions. Water stains are washed off with detergent.
3. All cracks and holes are sealed with mortar and putty. Use only moisture-resistant putty mixtures based on polymers or cement.
4. After this, the ceiling is primed in three layers and dried.

Calculation of the required amount of material

As a rule, the packaging with the composition indicates its approximate consumption, taking into account the thickness of the coating. Usually the mixture is applied in a layer 0.1-0.15 cm thick, so one kilogram is enough for 3-6 squares of ceiling. The exact consumption depends on the texture of the mixture.

Important! Please note that any defects or irregularities on base surface increase mixture consumption.

To calculate the amount of material, divide the ceiling area by the area to be covered, which is indicated by the manufacturer on the pack of dry composition. Round the resulting number up to a whole number. If there is a slight discrepancy in the color of the dry mixture, it can be mixed in one container and diluted with water during preparation.

Applying wallpaper to the ceiling

While working, adhere to the following recommendations:

1. First, the dry mass is diluted with water and waiting for it to swell. The waiting time is usually indicated on the packaging and ranges from a quarter of an hour to several hours. Optimal temperature water 20-25 degrees. If necessary, coloring pigments are added to the water. You can also add decorative additives to the solution and mix. At the end, add the dry wallpaper mixture. After mixing, wait the specified time and mix the solution again. It is now ready to use.
2. The texture of the wallpaper depends on the direction in which you apply the mixture. It is especially important to take this into account when applying mass with large fibers.
3. Before application liquid composition on the ceiling you need to fix all the decorative elements and ceiling skirting boards. Because then they won’t be able to be glued to the porous surface of the coating.
4. The mixture is applied using a wide spatula in a thin layer and smoothed well with a roller or plastic grater. The material is glued in separate sections, well leveling their boundaries.
5. It is better if you process the entire ceiling in one go. This way you will avoid the appearance of visible plot boundaries.
6. To apply the mixture, you can use not a spatula, but a spray gun with an extended nozzle. The resulting rough coating is rolled with a textured or hard roller.

IN more often already simple methods ceiling decorations do not attract attention and sometimes a person wants something special, soft and cozy... An option for decorating the ceiling with your own hands can be liquid wallpaper. Modern liquid wallpaper can be purchased and applied to the ceiling yourself. This does not require great painting skills, but you will still have to try.

So, first you need to look at the wallpaper and purchase, for example, Silk Plaster liquid wallpaper → https://silkstar.ru/catalog-zhidkie-oboi/. Any type of liquid wallpaper is suitable for the ceiling. Be sure to tell the seller the area of ​​the room and take a small margin (10-15%) to be sure.

Features of finishing the ceiling with liquid wallpaper

Liquid wallpaper, or, as it is correctly said, “silk plaster,” has its own application characteristics. Naturally, we will consider all of them further.

Finishing room

Liquid wallpaper can be applied to the ceiling in any room, but there is a nuance to finishing the ceiling with it in a bathroom or other room with high humidity. So, after applying liquid wallpaper to the ceiling in the bathroom, they will need to be varnished for water based, applying it in 2 layers after the liquid wallpaper has dried, the drying process of the liquid wallpaper will last 2-4 days.

The varnish can be colorless, matte or glossy - it’s your choice.

In any other situations, liquid wallpaper is applied to the ceiling in the same way.

Preparing the base

Preparation of the base needs to be given Special attention. And here there are 2 ways:

1. Prepare the base well: primer, plaster (leveling), putty...
2. It's easier to prepare the base.

If with the first option “everything is clear” - everything is done according to the classic finishing, then in order to apply liquid wallpaper on not prepared ceiling quality, you need to understand some nuances.

In the first case, you need to understand how to carry out the work, and in the second, how to make sure that this work is not necessary and get high-quality coverage.

In general, silk plaster is not demanding on the quality of the base, since it is a thick tissue-cellulose mass and naturally covers any irregularities and depressions. But it all depends on the specific situation.

1. If the ceiling has a horizontal difference, then in this case it is still better →, since a horizontally crooked ceiling cannot be hidden with any finishing. This applies to ceilings with a noticeable deviation; if the deviation is less than 0.5-1 cm over the entire area, then the unevenness of such a ceiling may not be noticed.
2. If the base has bulges, it is better to knock them off, or again bring out the entire plane → .
3. Small depressions are not important; they will be covered with liquid wallpaper, respectively, if you do not prepare the base. Again, it’s better to prime the ceiling and putty it with gypsum putty, at the same time you’ll practice, because particularly liquid wallpaper is no different from putty.

Pasting the ceiling with ordinary roll wallpaper can be a very difficult and time-consuming process, especially if the surface is far from ideal. A good alternative in this case could be liquid wallpaper for the ceiling, which imitates traditional finishing materials and plaster. It is noteworthy that liquid wallpaper allows you to quickly finish the ceiling and disguise small defects in the ceiling. How to glue liquid wallpaper to the ceiling, as well as the types and advantages of such finishing, will be discussed later in the article.

Types of liquid wallpaper

One of the main features of liquid wallpaper is that it harmoniously combines with many finishing options, and can also be used to decorate walls, ceilings and any other surfaces, even quite complex ones. geometric shape. At the same time, the exterior of the coating looks beautiful, smooth, without seams or joints.

Liquid wallpaper should be understood as a composition of textile fibers or cellulose with various additives. On sale, liquid wallpaper is found both in dry form, that is, it requires dilution with water before use, and in ready-made, liquid form. Apply liquid ceiling wallpaper very simple, the process is very similar to using ordinary plaster and putties. For this property, some people call liquid wallpaper silk plaster.

The classification of liquid wallpaper involves their division according to the following characteristics:

• according to the size of the fibers - smooth or with a relief pattern;
• according to color scheme - colored or white, with the possibility of tinting in any color;
• in composition - a homogeneous mass or with additives that give a certain texture;
• by type of base - silk, cotton, cellulose, mixed.

Depending on the fraction of additives, the texture of the coating changes, that is, the larger the particles of the base material, the rougher the surface will be as a result. If the apartment owners intentionally want to get a textured coating, you can walk over the still wet layer of liquid wallpaper on the ceiling with a special roller, giving it relief.

Liquid wallpaper is available in a wide range of colors, so you can recreate any shade you like. However, it is worth remembering that after applying the material to the wall, the final color will be slightly darker than the wallpaper in its original dry form. If you don’t like or suit any of the presented shades, you can tint the mixture yourself by adding the desired color to the white base.

All sorts of additives give the liquid ceiling originality and presentability. You can find mixtures with stone chips, glitter, textile threads made of cotton or silk, and cellulose inclusions. In each case, the finished coating will have different effects. Thus, based on the desired interior, you can choose the type of liquid wallpaper.

It is worth noting that the composition of the silk plaster on the ceiling will also determine the durability of the coating, as well as its wear resistance and ease of use. The cost of the finishing material also largely depends on the type of base.

Wallpaper with cellulose base

This finishing material is the most affordable for the consumer, since it uses cheap components. In addition to the cellulose fibers themselves, such liquid wallpaper contains plasticizers, glue, coloring pigments, and sometimes some decorative additives.

This type of wallpaper adheres well to any type of surface, since cellulose itself has adhesive properties. However, cellulose liquid wallpaper is sensitive to direct sunlight, so it is advisable to use it in shaded, cool rooms, such as corridors or hallways.

Blends with cotton fibers

Shredded cotton fibers are used as the basis for this type of wallpaper, which provides a soft texture and matte finish. Cotton itself is environmentally friendly pure material Therefore, such wallpaper is safe to use for decorating children's rooms and bedrooms. In addition, cotton liquid wallpaper provides good heat and sound insulation.

Silk-based liquid wallpaper

This type of liquid wallpaper is the most expensive, although it is durable, wear-resistant, presentable in appearance with a pleasant shine. The wallpaper obtains all these qualities thanks to the inclusion of natural silk fibers.

Such wallpapers last a long time original color, therefore can be used to decorate rooms with good lighting, panoramic windows. The texture of wallpaper can be varied - from imitation of a fabric surface to marble.

Mixed materials

In this case, one mixture may contain additives of several types - cellulose and fabric in different quantities. This way a beautiful decorative effect is achieved affordable price. The cost of the material will depend on the proportions of the materials included in the mixture, as well as their type.

Some components, such as metallic glitter or mineral additives, can be purchased separately. If desired, they are added to the mixture of liquid wallpaper to give the coating one or another decorative effect.

Points for and against"

Before applying liquid wallpaper to the ceiling, it is worth considering all the positive and negative sides this solution, so as not to experience inconvenience and irritation later.

The undoubted advantages of liquid wallpaper include:

• environmental friendliness, that is, exclusively natural composition which does not retain moisture and does not interfere with air circulation;
• Smooth surface without seams and joints, even not quite perfect ceiling;
• ease of preparing the ceiling for processing;
• any creases or folds are excluded;
• possible various options textures - the surface can be smooth or with a relief pattern;
• diversity color range and additives that give a decorative effect.

In case of any defects, individual sections of the ceiling with liquid wallpaper can be repaired.

Among the disadvantages of this material are:

• high price of the material - it costs about 2-2.5 times more than traditional wallpaper;
• if the material gets wet, it will peel off, as it is not moisture resistant;
• most cheap look wallpaper (cellulose) is sensitive to ultraviolet radiation and fades quickly;
• Working with the material requires a certain amount of skill.

Although the list of shortcomings is not so short, most of them are leveled out by a competent choice of material, its correct use And further care behind the ceiling. Wallpaper with a textile fiber content of 30-40% will be more durable. And if you coat the material with water-repellent acrylic varnish, you can increase its moisture resistance. How to apply liquid wallpaper for the ceiling is usually written on the packaging.

How to properly apply liquid wallpaper to the ceiling

In general, the process of applying liquid wallpaper to the ceiling includes two stages:

• preparatory work;
• directly covering the ceiling with finishing material.

Preliminary preparation of the ceiling for liquid wallpaper must be carried out very carefully, since it will affect the process of subsequent application of the material and its adhesion to the surface.

Scale preparatory work depends largely on the type of rough surface. In new homes, the ceilings are usually plastered, so only priming is required. And if there are any finishing materials, such as old wallpaper or whitewash, they will have to be completely removed.

If starter plaster is applied to the walls or ceiling of the apartment and it does not need leveling, then you will need to apply at least 2 layers of deep-penetrating primer. Each layer should dry for 3-4 hours. You can use a brush or roller to apply the primer. In this case, the direction of strokes in each approach should be perpendicular to the previous one. When the base is dry, you can apply liquid wallpaper to the kitchen ceiling.

To cover with liquid wallpaper suspended ceiling from plasterboard or fibreboards, the surface can only be primed and the primer allowed to dry completely. All possible gaps between the plates will be filled with liquid wallpaper. When applying primer to drywall, make sure that the roller is not too wet, otherwise the material will begin to delaminate.

If there are old paper or liquid wallpaper left on the ceiling, they must be completely removed. The paper needs to be wetted and then removed with a spatula. You also need to wash off the stuck old glue. Liquid wallpaper also needs to be soaked. It is worth spraying water on them, and then using a wide spatula to scrape the material from the ceiling. After removing the old coating, the ceiling needs priming, as in other cases.

Must be removed old paint or whitewash from the ceiling. If the surface was covered with chalk or lime, it is soaked with water or a special remover, and then scraped off with spatulas and washed. For enamels and acrylics paint coatings You will need a spatula or sander to remove any loose areas. Upon completion of grinding, the surface is cleaned of dust and a primer is applied.

Especially actual problem with old ceilings there are all kinds of greasy spots, traces of flooding by precipitation or neighbors from above, as well as rust stains from old metal elements.

Rust on the ceiling can be removed with weak solutions of phosphoric or hydrochloric acid. Apply acid to the stain with a brush and wait until the stain disappears. The remaining substance is washed off with water. When the treatment area is completely dry, metal parts apply moisture-resistant putty, and then cover it with a layer of white enamel.

Grease on the ceiling can be removed with alkaline substances or with the addition of surfactants. For example, the composition can be prepared from soda ash, laundry soap And warm water. This solution should be applied to the stain, and after a few minutes, washed off. The procedure is repeated several times until the stain completely disappears.

If stains from leaking water appear on the ceiling, they can be removed with a regular brush. Especially stubborn stains can be treated with bleach or vinegar. When the ceiling is cleaned, it is primed again, and you can begin finishing.

If the cracks in the ceiling are too large, before gluing liquid wallpaper to the ceiling, you should plaster them and then apply a layer of fine-grained putty. It is advisable to use moisture-resistant putty based on polymers or cement. When the material has dried, the surface is treated with a primer in 2 or 3 layers, drying each separately. After this, you can apply liquid wallpaper.

Since the removal of old finishing materials is always accompanied by a large amount of dust and dirt, it is advisable to remove the furniture from the room, or at least carefully cover it with film.

How to calculate how much material you will need

Before making the ceiling with liquid wallpaper, you need to correctly calculate the amount of material that will be needed to cover the entire surface. This is especially important if you initially use white liquid wallpaper on the ceiling, which is tinted to the desired color immediately before application. To make the color uniform, mix the entire amount of wallpaper at once.

The approximate consumption of material is indicated on the packaging with the mixture. If you cover the ceilings with a 1-1.5 cm layer of liquid wallpaper, then a standard 1 kg package will be enough for 3-6 m2 of surface, based on its texture. If there is minor damage to the rough surface, material consumption may increase. It is worth remembering this when purchasing a mixture for liquid wallpaper.

So, the calculation of the material is carried out based on the size of the room and the minimum area that can be covered. For example, for a room of 20 m2, a mixture is purchased, the consumption of which is 3-4 m2 per 1 kg. Therefore, you will need 20÷3 = 6.6 ≈7 packages of dry mixture.

Please note that it is not worth buying a mixture for liquid wallpaper practically end-to-end, because if there is not enough material for the job, a joint may remain on the ceiling, and it will be quite difficult to choose a shade.

If the color of the mixture is different in several packages, it is necessary to combine the contents of all packages, mix thoroughly, and then dilute with water. Mixing the composition gradually or immediately is everyone’s personal choice.

Covering the ceiling

To avoid mistakes and imperfections, let’s take a closer look at how to properly apply liquid wallpaper to the ceiling.

First we start preparing the working mixture. To dilute the dry mixture, use ordinary water at room temperature (20-25 ℃, not warm). It is added according to the instructions, and then the solution is left for right time for swelling. Different compositions require 15 minutes to several hours to fully swell. This information is indicated on the packaging of the dry mixture.

If you need to tint white wallpaper, add the dye to the water, then pour it into the dry mixture and mix thoroughly. Depending on how much dye is added, the intensity of the shade of the liquid wallpaper will change.

If decorative components are used, such as shavings or granite chips, they must be added to the dry mixture and mixed. Then the dry mixture is carefully added to the water and mixed. If there is not much material, then you can prepare the solution manually. However, a more uniform composition will be obtained if you use a construction mixer for average speed. You should not turn on too high speeds, so as not to saturate the solution with oxygen. After the mixture has stood for the required time, it is re-mixed and can be applied.

It is very important to understand how to properly apply liquid wallpaper to the ceiling, that is, what technique to use. The final texture of the wallpaper depends on the direction in which the trowel moves. So, when applying liquid wallpaper in circular, transverse or longitudinal strokes, the fibers of the material will lie differently. This is especially noticeable if the liquid wallpaper has a coarse-grained structure. In this case, the strokes should lie in the same direction across the entire ceiling so that the appearance is not spoiled. To get the hang of it, you can try applying the material to a flat surface.

The next stage is equally relevant for suspended ceilings and liquid wallpaper. It includes the installation of decorative elements, moldings, borders and baseboards. However, unlike paper materials, when working with liquid wallpaper, the entire decor must be fixed before the ceiling begins to be covered. Since liquid wallpaper has a porous surface, decorative stucco and the moldings simply won’t hold up.

To apply liquid wallpaper to the ceiling, you can use a trowel or spatula. Having applied thin layer material, they pass over it with a roller or plastic grater and add texture. Cover the ceiling in sections. In this case, each subsequent segment slightly captures the edges of the previous one. The edges are carefully leveled. To ensure that the joints are not visible, the entire volume of material must be applied in one go, until they are dry. Alternatively, you can use a spray gun with a wide nozzle to apply liquid wallpaper. They pass over the applied layer with a hard (a smooth surface is obtained) or a figured roller (the desired relief is achieved).

For completely dry Wallpaper requires about 12-72 hours, based on the characteristics of the surface and the mixture used. There is no need to ventilate the room or turn on the heater to allow the wallpaper to dry more evenly. You can extend the durability of liquid wallpaper by applying moisture-resistant varnish.

DIY liquid wallpaper

If desired, liquid wallpaper can be made with your own hands. To do this you will need 40 sheets of paper. They, whole or crushed, are placed in a container and 1.25 liters of water are poured. An hour later, when the paper gets wet, the mixture is crushed with a drill and mixer. Then add 2 caps of dye to the mixture and mix again. Now you need to add 40 small spoons of gypsum. The better quality it is, the faster the wallpaper will begin to harden. Next, pour 200 ml of PVA glue into the mixture and mix again. The composition is ready. It can be applied to the ceiling.

It is noteworthy that such a composition can be applied over the old ceiling covering. The exception is whitewash - it should be washed off and the surface should be puttied a couple of times.

Thus, liquid wallpaper is not only a way to provide a reliable and durable ceiling covering, but also an opportunity to make it more decorative. That's why this type finishing is becoming increasingly popular among interior designers and professional craftsmen repair. You will also be able to deal with liquid materials. Follow our recommendations and you will succeed.
