Drywall becomes the best option when it is necessary to perform roughing. The surfaces become perfectly smooth, and the work process is not as labor-intensive as when using putty. Typically, sheets of drywall were mounted on a specially made one. But this method greatly complicates the work, makes it less effective and costly. If technically possible, it is best to glue drywall.

Today we will learn exactly how to properly glue drywall. Let's take a closer look at the most important points and consider some useful tips.

Surface preparation

The technology of the process of preparing surfaces for gluing plasterboard sheets will completely depend on the condition of the walls and their unevenness. Let's consider the main preparation options.

The wall is almost flat

It is usually most convenient to work with concrete walls. When the wall is almost flat, you can use less glue. But good preparation still necessary.

It’s better to start by chipping the walls for subsequent careful laying of the wiring. Remember that in wall covering It is necessary to make the appropriate holes in advance, which are intended for switches and sockets.

Experts note: walls must be primed before gluing drywall. The most suitable primer mixture is specially selected: it can be intended for painted concrete or for untreated surfaces. The primer plays a significant role: it will be absorbed into the concrete and increase surface adhesion. Also, the primer layer prevents the formation of condensation and the development of fungi.

Surface with medium-sized irregularities

Walls made of aerated concrete, foam concrete and brick have more significant irregularities. The basic techniques for surface treatment will be the same as for concrete walls. It is necessary to make recesses for laying the wiring, and priming is also carried out. It is important to remember that for good adhesion you will need a thicker layer of glue.

Brickwork demands to himself special attention. It is necessary to eliminate noticeable depressions, protrusions, and cracks. It is usually customary to use leveling putty. But sometimes it's not enough. Then you can use polyurethane foam and pieces of drywall.

Gas blocks, foam blocks easier to process. But they may also have significant defects resulting from mechanical damage. Most often this happens during transportation. You need to use a gypsum mixture to reliably eliminate all flaws.

Walls with serious defects

Large irregularities are considered to be defects with a size of more than 20 mm. If the walls are so uneven, you should study them more carefully: it may be possible to lay wiring with them even without preliminary gating. In this case, you will need clips, clamps or brackets to secure the wires.

It is convenient when channels form naturally in the walls. If they are suitable for installing electrical wiring, it is fixed to alabaster or plaster.

To reliably glue sheets of drywall to walls with significant unevenness, you will have to create something like a frame. Strips are cut out of drywall. The width should be 100 mm. Glue the strips vertically around the perimeter of the walls. It is better to take a step of 50-60 cm.

When installing drywall sheets, they are not attached with self-tapping screws or self-tapping screws, but rather are glued to the frame. pay attention to important point! Frame tapes will not only be the basis for gluing the material, but also beacons of sorts. They must be fixed perfectly evenly. Use rules and levels to achieve maximum form accuracy.

Glue drywall

Choose quality glue. There is no need to save money here, since the quality of the entire finish and the strength of fixation of the drywall sheets largely depend on the reliability of the adhesive composition.

If the walls are already completely prepared, cleaned and primed, you can begin lining with sheets of plasterboard.

1. Some masters prefer to apply adhesive composition directly onto the load-bearing surface, that is, onto the walls. However, at home it is much more convenient to apply glue to drywall when the sheets lie horizontally.
2. Much depends on the consistency of the adhesive mass. It is necessary to do everything exactly according to the instructions so that the glue does not spread or blur, but forms easily and conveniently, in medium-sized lumps. It should be doughy, a little like thick sour cream, and not liquid.



3. Apply glue in increments of 25 cm around the entire perimeter of the sheet. The volume of the adhesive layer itself will depend on the degree of unevenness of the wall surface. It is in the range of 5-25 cm. You can work with ready-made glue for a maximum of 20 minutes, otherwise it will begin to set.
4. The glue must be applied carefully, but quickly enough. It is recommended to fix the sheets at a distance of approximately 2 cm from the floor surface. The very first sheet of drywall plays a huge role, which will already become a guide for the rest. Use the rule to ensure that the fixation is as even as possible. Mark the beacons in advance and check with them. The sheets must be adjusted to each other.



5. On next stage You will need to process the seams between the sheets. It is advisable to use a mixture High Quality, since the seams also have great importance. First, the seams themselves are filled with putty.
6. Then you need to secure the reinforcing tape.
7. Don't forget about protection external parts drywall: they are protected with corners.
8. To ensure a completely smooth surface, finishing putty. It is applied thin layer, and then rubbed with a sponge: wet and dry.

A fully prepared wall, properly covered with plasterboard, is optimal for almost any decoration: tiles, wallpaper, paint, decorative plaster.

Leveling walls with plasterboard without lathing can significantly reduce repair costs. Today we will tell our dear reader about how to glue drywall to walls - a video demonstrating the technology and photographs of different stages of work will help us with this. So, let's go.

Lathing or glue

When can you attach drywall to walls with glue, and when should you prefer traditional installation using lathing?

Plasterboard stickers on walls are permissible if two conditions are met:

1. They do not have pronounced curvilinearity, blockages and other defects larger than 50 mm;
2. You do not need wall insulation or hidden gasket ventilation, water supply, sewerage and others engineering systems large section.

What to glue

What kind of glue can gypsum boards be attached to? Using mounting gypsum adhesive (Perlfix from Knauf, Volma Montazh, etc.).

However: it can be perfectly replaced by any gypsum putty or plaster. The price of these building mixtures differs slightly, and they all have excellent adhesion to kraft paper - the shell of drywall.

Is it possible to glue drywall to a wall covered with old tiles or oil paint?

Can. But in this case, it is not gypsum glue that is used, but polyurethane foam. It has excellent adhesion to problematic surfaces.

Work technology

How to glue drywall to a wall with your own hands using gypsum glue?

If you want to see more clearly how we glue drywall to the wall, the video in this article will help you.

Preparing the walls

Let's start by preparing the base:

Image	Stage of work
	The walls are cleaned of weak and low-adhesive coatings. The crumbling plaster is removed with a hammer drill (see How to remove old plaster from walls without problems), the whitewash is removed with a spatula after soaking with water, the paints are treated with a universal remover and again removed with a steel spatula.
	The cleaned surface is primed (see Why a primer is needed: technological nuances of finishing work). The primer will improve the adhesion of the gypsum adhesive to the surface of the wall, making it more durable and adhering to dust particles. On plastering and brick walls penetrating acrylic primer is used, on a concrete monolith or panel - concrete contact (adhesive primer with the addition of sand).

Attention: if there are large areas of oil or grease stains on the wall, they must be removed before priming. Degreasing is carried out with a regular rag with gasoline or any organic solvent.

Mixing the glue

Instructions for preparing glue are quite standard for gypsum building mixtures:

1. Pour into metal or plastic container clean water;
2. Pour gypsum glue into the water at the rate of 2 kg per 1 liter of water;
3. Mix the mixture until smooth with a construction mixer or a whisk clamped in the chuck of a drill or hammer drill in drilling mode.

Useful: after mixing, the glue is usable for about half an hour. The average consumption is 5 kg of dry mixture per 1 m2.

Installation of gypsum boards

How to cover walls with plasterboard after preparing them:

1. Apply glue onto the back of the sheet or onto the wall. Step - 15-20 centimeters;

A nuance: it is advisable to apply a continuous bead of mounting adhesive along the edge of the sheet adjacent to the floor. It will greatly simplify the installation of the plinth.

1. Press the plasterboard and level it with a long level using a rubber mallet or palm;
2. When installing the next sheet, carefully ensure that both the edges and surfaces of adjacent sheets lie in the same plane. Installation flaws will have to be corrected with a thick layer of putty.

How to glue drywall to walls with large (over 2-3 cm) irregularities?

Use beacons that will help align the sheet in one plane. The role of beacons can be gypsum board scraps secured with the same mounting adhesive, dowel screws partially screwed into the wall, and any other available material.

How to glue drywall to walls using polyurethane foam:

1. Apply it in strips with increments of about 20 cm;
2. Press the sheet against the wall and rub it in with a couple of sliding movements. This is necessary in order to destroy the bubbles in the foam structure and turn it into ordinary polyurethane glue that will not expand during polymerization;
3. Over potholes and blockages in the gypsum board wall, you need to additionally fix it with dowel screws in increments of no more than 25 cm. The reason is the notorious expansion of the foam, which can bend the drywall.

Pre-finishing

We figured out how to glue drywall to a wall. However, the work is still far from finished: the walls are decorated with untidy seams between the semicircular edges of individual sheets. How are plasterboard walls prepared for wallpapering or painting?

Tools and materials

For this you will need:

Image	Description
	Serpyanka is a reinforcing material, which is a narrow (5-8 cm) fiberglass mesh with an adhesive layer on one side. Reinforcing the seams will save them from cracks during seasonal fluctuations in humidity and temperature in the room.
	Gypsum putty (universal or finishing).
	Container for mixing putty. The author uses a plastic bucket of water-based paint for this purpose.
	A pair of spatulas (10-12 and 30-35 cm wide).
	A grater or grinder with abrasive mesh.
	Penetrating soil. It will reduce the consumption of paint or wallpaper glue, and at the same time glue the dust remaining on its surface to the gypsum board.

Technology

1. We chamfer the rectangular edges of the sheets cut in place. The so-called jointing will allow you to fill the joint as deeply as possible during puttying, making it extremely durable;
2. We glue sickle tape along the seams and immediately putty them directly through the cells of the fiberglass mesh. For filling the first layer, it is convenient to use a narrow spatula. It is better to apply the putty crosswise, with transverse movements: this way the seam will be filled as tightly as possible (see Puttying drywall seams - how to do it);
3. We wait for the first layer to dry (6-18 hours depending on humidity and temperature), after which we cover the serpyanka with a second layer of putty, using a wide spatula;

1. After completely dry plaster, sand the seams. When sanding, it is advisable to illuminate them brightly at an oblique angle: this way you will not miss a single irregularity;

1. We sweep away dust from the walls or vacuum them, and then prime them with penetrating primer.

A nuance: it is advisable to putty a millimeter layer of gypsum board under the wallpaper over the entire surface. Otherwise, in the future, when removing wallpaper placed on plasterboard walls with glue, you can tear off the cardboard shell of the gypsum board from the gypsum core. Separating layer putty will help you do without excesses.

Finishing

It does not have any features in the background finishing plaster walls: wallpapering on plasterboard walls is done using regular wallpaper glue KMC; Water-dispersed dyes are used for painting. GKL tiles can be laid with regular tile adhesive or spot-applied silicone sealant.

Conclusion

As you can see, frameless alignment The walls are not difficult and are quite within the capabilities of a beginner. Good luck!

Despite all the advantages, finishing with plasterboard, which is attached to the frame, has one serious drawback. With such cladding occurs noticeable loss usable area rooms.

This is especially noticeable in small apartments. To avoid such losses, technologists asked themselves the question: is it possible to glue drywall to the wall?

And this problem was solved. If the level of the surfaces in your apartment allows, it is quite possible to glue plasterboard sheets directly to the walls.

The use of glue instead of lathing allowed us to avoid significant losses of room space.

What kind of walls should there be?

How to determine whether gluing drywall to the wall is possible in your case.

To use the method of attaching gypsum boards with glue, the wall surface must meet the following requirements:

1. The wall must be fairly level tolerance it can be no more than two centimeters, otherwise the gypsum board will not stick.

1. Surfaces intended for gluing drywall to the wall should not freeze. Since in this case it is not possible to install thermal insulation.
2. A good basis for planting gypsum boards on glue are concrete panels. Even if they are not installed completely vertically, the main plane of the slab is quite flat.

The next question that arises is what to use to glue drywall to the wall?

Knauf has developed technology and created special adhesive compositions for cladding gypsum board surfaces without a frame.

Drywall gluing technology

Gluing gypsum boards to relatively flat walls

Now we will tell you how to glue drywall to a brick wall.

First of all, you need to check how smooth the surface is. This can be done using a long level, a rule, or a stretched cord.

The permissible deviation from the vertical is within 5 mm.

How to glue drywall to a wall, you ask. This can be done using gypsum putty on adhesive basis Knauf Fugen.

Step-by-step instructions for covering walls with plasterboard using the gluing method:

1. First of all, you need to clean the surfaces from dirt, dust and greasy stains. The walls must be completely dry.

1. Then the surface is primed to reduce moisture absorption and enhance adhesion.

1. If necessary, low-current wiring is installed along the wall. Power electrical cables must be buried in the grooves.

1. The height of the sheets is measured and cut so that after gluing there is 10-15 mm left to the floor.

1. Holes for switches and sockets are first prepared in the plasterboard.

1. To avoid mistakes in difficult areas, it is better to cut the piece in place after the previous piece has been glued.

1. After the sheet is prepared for gluing, a strip of gypsum putty 12-15 cm wide is applied along its entire perimeter with a notched trowel. Also one or two stripes are superimposed in the center. If the sheet thickness is 12.5 mm, one strip in the center is enough, for a thinner one, it is better to make two.

1. In that part of the gypsum board where there will be a large load - it is planned to tiling or a shelf, and where there is an abutment to a window or door, the adhesive is applied to the entire surface.

Note! To prevent the gypsum board from breaking during the application of putty, it is better to place it near the gluing site and it would be good to place a frame of bars under it.

1. The next step is to carefully lift the sheet, place it on pads and press it against the wall over its entire surface. Then the protruding parts are determined by the level, and, slowly pressing on them, the plane is leveled. The vertical flatness of the surface is also checked.

1. After gluing all the sheets, the joints are puttied. The gap between the floor and the gypsum board is sealed with putty or sealant.

Advice! It is better to do the work of gluing drywall yourself with an assistant. It’s more convenient to do this with two people, and the weight of the plasterboard can reach 30 kg.

The principle of spot application of glue on a plasterboard sheet

If the surface of your walls is not completely flat, but the difference is no more than two centimeters, you can still stick plasterboard sheets. How to glue drywall to concrete wall, you ask. For such cases Knauf company has developed a special dry mixture Perlfix.

Procedure:

1. First of all, you need to carry out preliminary markings in order to subsequently position the gypsum board in one plane.

1. To do this, draw a straight line on the floor and ceiling at a certain distance from the wall. To mark, you will need a tracer (thread with dye applied) and a plumb line. These lines will serve as a guide during installation to align the position of each sheet relative to the general plane.

1. Perlfix gypsum glue is applied with a trowel in small piles along the entire perimeter of the sheet, after about 20 - 25 cm. Hills are also laid out on the remaining part of the gypsum board adhesive solution, but the distance between them increases to 30 - 40 cm.

1. Then the sheet is carefully lifted, applied to the wall and aligned with the reference points.

1. After the adhesive has dried and hardened, you can proceed to sealing the seams.

A video on gluing gypsum boards to walls will clearly show all stages of the work.

Conclusion

If the walls in your apartment are fairly smooth, you can easily use the technology of gluing gypsum boards. The price of this method is much lower, because there is no need to make a metal frame.

And the saving of usable space is obvious. The main thing is to follow the instructions and maintain the levels.

The installation method, in which a sheet of drywall is attached to vertical surface glue, there are a number of undeniable advantages. It allows you to simultaneously glue the material and level the walls, protect coatings with reverse side from exposure aggressive environments and the harmful effects of microorganisms, thanks to the ease of installation technology, budget and personal time are saved.

Installing drywall with glue saves space in the room, which, if the frame was installed, would be 5-6 cm less on the side of each wall. To perform a quality installation, you will need:

• decide on the choice of glue;
• prepare the surface;
• Follow the installation instructions.

The process of gluing a gypsum board sheet

To install a sheet of drywall on a wall using the adhesive method, use products from two reputable manufacturers: Knauf (Perlfix series, Germany) or Volma (Montazh series, Russia). The use of a domestic brand is preferable for the following reasons:

• the cost is lower;
• the mixture consumption for applying a layer with a thickness of 1 mm and an area of ​​1 m² per serpyanka is only 2-3 kg, compared to 5 kg of the Knauf brand;
• The complete drying period for Volma glue is 24 hours, for the Knauf mixture it reaches 7 days;
• strong adhesion to the surface due to the content of gypsum fibers;
• setting time of the mixture flat surface is 1 hour, with Perlfix this threshold occurs 30 minutes after mixing; if the mixture is applied to a sickle tape, the setting period is even shorter (40 and 15 minutes, respectively);
• It easily takes the shape of irregularities and does not shrink after hardening.

For DIY installation, it is preferable to use Volma glue. For a beginner, the packaging form of the material is also convenient - 5, 15 and 30 kg. This makes it easy to calculate the material, save on costs, determine the amount of work in advance and have a certain period of time left before the mixture has time to set. Knauf adhesive mixture is designed for a professional approach. Packaging form: 30 kg.

To glue a sheet of drywall to a wall with Knauf mixture, you will need professional skills to work at a fast pace. Packaging form Perlfix – 30 kg. Optimal temperature for the mass to acquire its properties - +5 degrees under normal humidity conditions.

Volma glue packaging form Installation

Surface preparation

Before you start gluing a sheet of drywall with Volma glue, prepare the surface for it. To do this, using a level or a stretched cord, a series of measurements are made to reveal irregularities at the base of the walls. If deviations do not exceed 2 cm, proceed to the following steps:

• clear the walls of old decoration(wallpaper, paint, plaster), dust and other contaminants;
• the surface is covered with two layers of primer, which increases the level of adhesion of the material from which the vertical ceilings are made (brick, concrete, wood) with glue;
• if deviations in curvature are slightly more than 2 cm, a layer of plaster is applied to the wall, this will smooth out the unevenness, which will then be filled with glue;
• then they calculate the layout of the plasterboard sheets so that after installation they do not touch the floor at a distance of 10-15 mm (this space is required for climatic adaptation of the material);

On a rough wall, you can install a sheathing or glue sickle tape, which will allow the glue to adhere even more firmly to the wall.

Applying plaster over serpyanka

Glue installation

As tools for gluing a gypsum board sheet with your own hands, you will need:

• bucket or basin for kneading;
• drills or mixer;
• building level;
• trowel and spatula for applying glue;
• hammer with a wide board.

Installation steps:

• dilute the glue in a bucket of water in the proportions indicated on the Volma package;
• the mass of the mixture is calculated depending on the volume of work performed and the curvature of the walls, on average it is 10-12 liters, so that it does not have time to set;
• apply the adhesive mixture to the wall or to the sheet of drywall itself, evenly distributing it over the surface in small dots in a checkerboard pattern in increments of 40 cm or in strips 15 cm wide. This application will allow you to adjust the location of the plasterboard relative to the vertical and horizontal plane;
• It is recommended to glue the gypsum sheet from the corner of the room; to do this, it is carefully pressed against the wall and leveled;
• if the level shows that the sheet is lying unevenly, tapping it with a hammer wooden board distribute the glue applied on the reverse side more evenly, reducing the resulting voids.

Distribution of glue over the surface of the gypsum board sheet and its correct consistency

After installation is completed, sickle tape is glued to the joints between the sheets of drywall for additional reinforcement of the seams. The gaps between the joints are filled with Volma glue or special putty. Each seam is carefully processed so that subsequently moisture does not get between the joints and destroy the structure of the gypsum boards.

After the mass has dried, the serpyanka is treated with trowelling sandpaper to remove excess glue, a primer is applied again and, after it has dried, the surface of the drywall is puttied. All stages of installing gypsum boards using the adhesive method are shown in the video below.

On a note

Remember, if the unevenness reaches 10 cm, it is not allowed to glue drywall onto the Volma mixture, because the end result will not be of high quality: the sheet will not be able to fit tightly to the surface, and the adhesion strength will be impaired. And the glue consumption will be unreasonably high.

Proper execution measuring walls before gluing gypsum boards - the basis high-quality installation

In such cases, it is recommended to standard installation metal or wooden frame. This installation method will allow you to additionally insulate plasterboard walls and hide cables and pipes. Using glue method It is not possible to carry out such work or great efforts are required to drill special grooves for electrical wiring.

In contact with

In order to make walls even in rooms, plasterboard sheets (GKL) are often used. The main type of fastening is a frame made of wooden slats or metal profile, which serve as the basis for installation. But such a design, after installation, takes away useful territory, so it is undesirable to use frame technology V small rooms. In this case, you may need to glue the sheets directly onto the wall plane. The method of frameless installation using gypsum plasterboard involves the use of adhesive mixtures.

In what cases can drywall be installed with glue?

Fastening to a concrete wall plasterboard sheets relevant in several situations:

• In small rooms, in order to preserve usable space.
• If necessary, level out the curvature of the walls and differences of up to 50 mm.
• To create an even ceiling surface without reducing the height of the ceilings. Such work becomes more complicated due to the heaviness of the sheets themselves, which requires the use of additional fasteners. Dowel screws are used, which are located in increments of 60 cm between the fixation points.
• When finishing door and window openings.

Important! On walls where there are large irregularities and flaws, gluing plasterboard sheets is not economically feasible.

The frameless method of leveling walls using gypsum plasterboard is simple and accessible to everyone. For a high-quality and durable fixation of drywall to a vertical plane, you will need special glue. Various adhesive compositions are used to ensure reliable fixation to both vertical and horizontal planes. Ready-to-use mixtures are easy to use. You should understand in more detail how to glue drywall to a concrete wall.

Assortment for gypsum boards

Manufacturers offer a wide range of adhesive mixtures. The glue glues the gypsum plaster boards firmly and reliably.

The most common compositions are:

• for masonry ceramic tiles. The composition has good adhesion to smooth plasterboard boards.

• (Knife) affordable option, which may well be suitable for fixing gypsum boards to concrete and brick walls. Due to its ease of use, it is used in everyday life.

• - specialized gypsum-based mounting adhesive.

• Silicone-based adhesive adheres equally well to tiles and smooth plasterboard panels.
• - a dry mixture similar to putty, diluted for preparation cold water. To knead, you will need a drill with a whisk attachment. Apply a thin layer to the surface.

• (Knauf) is used as a gypsum board clamp to a flat plane. The mixture has increased plasticity due to polymer additives. The strength of the connection is created by a thin layer.

• Polyurethane assembly adhesive in a container with an aerosol dispenser. Such compositions are resistant to high humidity, provide reliable and durable fixation.

• Polyurethane foam with a slight increase in volume.

• Acrylic putties and sealants. Any type of sealant helps to stick drywall to brick, concrete or foam block walls.

Walls lined with plasterboard and using glue are inexpensive, so this method applies to budget repairs. Costs are also reduced due to the fact that the need to assemble a wooden frame or metal frame from profiles is eliminated.

Important! To improve the adhesive properties of gypsum plasterboard when joining with a concrete surface, a deep penetration primer is applied to the back side of the slab.

Preparing the walls

Before attaching drywall to a concrete wall, work surface Any dirt and dust present is removed. The paint layer is removed from the painted wall using an angle grinder, onto which flap sanding discs are installed. To remove dispersion or water-based paints, use a stiff brush.

The completely cleaned wall surface is treated with a special primer “Betonokontakt”. If the surface is clean and has a glossy coating that cannot be removed, then Betogrunt is used to give better adhesion.

The preparatory stage also includes a number of mandatory actions that will help determine the optimal option for attaching drywall:

• It is necessary to examine the working surface for curvature and the presence of flaws. This will require a rule or plumb line.
• Any protruding elements - screws, nails, concrete mounds - are removed from the walls.
• Old wallpaper is completely removed, other Decoration Materials until clean concrete surface. Such actions are labor-intensive, but they will increase the reliability and strength of the connection.
• For control correct installation sheets (in one plane) marks are made in the form of lines on the floor surface. Additionally, they can be applied to the ceiling if the vertical plane has large curvatures. The maximum difference should not be more than 2 cm.

Important! If the surface is smooth and has no flaws, then you should not increase the layer of glue to hide the wiring. It is enough to make grooves.

Knowing how to attach drywall to a concrete wall, you need to stock up on building materials in advance:

• Plasterboard sheets.
• Glue.
• Primer composition.
• Plaster mixture. This will be necessary if it is not possible to level the wall using drywall alone.

The number of gypsum plasterboards is determined in accordance with the area of ​​the walls. More complex calculations are performed when determining the amount of adhesive composition, since for each material the consumption per 1 sq. m. may vary. With a layer thickness of approximately 1 mm, up to 1.8 kg of glue is used. Each package indicates the quantity for a specific thickness of the applied layer.

Required Tools

To work you will need the following tools:

• Assembly knife for cutting plasterboard sheets.
• Level and plumb.
• Container for preparing plaster and glue mixture.
• A special attachment is a whisk, which speeds up the mixing process.
• Electric drill.
• Spatulas, including serrated ones, for distributing the finished adhesive mixture over the surface of the drywall.
• A mallet used to level the position of the sheets.
• Bars in the amount of 2 pcs.
• Pencil for making marks.

The choice of glue depending on the flatness of the wall

It is very important to choose the right way to glue drywall to concrete. For self-execution For non-professionals, it is better to use universal gypsum-based adhesive. Instructions for use are included.

It is worth talking about each type separately:

• The mixture prepared at home has a short shelf life - it must be used up within 30 minutes, because after the specified time it will lose its properties and will be unsuitable for use.
• The finished Fugenfüller putty is applied in a thin layer to the work surface. You need to know how to use this composition, which makes it accessible only to professionals.

• Silicone compositions are similar to Fugenfüller putty. They require skill to apply and are therefore not suitable for use by beginners.
• Perlfix gypsum adhesive is versatile. Even beginners can use this composition without much difficulty. The mixture is sold dry. To prepare, combine with water and stir until smooth. Application is carried out on the back side of the slab or directly on the wall. This adhesive composition not only securely fixes the drywall to the working surface, but also eliminates the curvature on the wall.

• Ceresit SM 11, although intended for laying tiles, is identical in application to Perlfix.

• Polyurethane foam is a reliable connecting material used to fix drywall to the wall. Foam with a low expansion coefficient is suitable for these purposes.

Important! Using foam requires knowledge and skill. Before foaming, all sheets should be installed in planes

Step-by-step instructions for gluing drywall to a flat wall

Exist different ways how to glue drywall to a concrete wall. Differences in performing such work directly depend on the condition of the surface. In order for the mounted sheets to stand and not peel off, you should know how and with what to glue drywall to a flat concrete wall.

Fixation on vertical plane carried out using any adhesive mixtures - gypsum or cement based, polymer mastic, mounting foam.

A notched trowel is used to apply the finished adhesive mixture. Small portions are distributed over the surface at a distance of 25 cm. After the entire area of ​​the sheet has been covered with glue, its lower edge is placed on the lining, the vertical position is leveled and pressed against the working plane. The mounted sheet is supported wooden block until the mixture hardens completely.

Step-by-step instructions for attaching gypsum boards to an uneven surface

The wall surface is distinguished by the irregularities present on it. What to use to glue drywall to a nervous concrete wall?

The choice of method depends on the degree of unevenness:

• For slight curvature of up to 2 cm, the Perflix adhesive composition is used, which is applied to the back surface of the sheet in small cakes. The application procedure is performed first along the perimeter in increments of 30 to 35 cm, and then the central part is filled.
• For deviations greater than 2 cm, the Fugen composition is used. The glue is distributed over the surface at intervals of 30-35 cm.

After applying the adhesive mass, the plasterboard sheet is lifted and placed on pads located on the floor. GCRs are aligned along the lines drawn on the ceiling and floor surfaces. It is necessary to ensure that the glue does not protrude through the seams; if this is observed, the excess should be removed with a spatula.

Important! When choosing a dry adhesive composition, it is necessary to take into account that the applied layer will be quite thick.

Walls with large irregularities

You should also know how to glue drywall to concrete uneven wall with bumps that cannot be removed. Here you will also need beacons to level the surface. You will also need to make a kind of frame from narrow strips of drywall. The sheet is cut with a knife into strips 10 cm wide, which are fixed vertically with Perflix compound at a distance of 40 to 60 cm. A level is used to check the correctness of the mounted slabs in the same plane. After the glue has completely hardened (after 2-3 days), the gypsum boards are installed using Fugenfüller or liquid nails.

Important! If there is an uneven surface with a large curvature, it is necessary to take as small a step as possible between the strips to ensure reliable fastening.

Completion of work

After the installation of drywall on the wall is completely completed, it is necessary to begin sealing the joints. The process begins with the application of putty for leveling. Then a reinforcing tape is applied to the fresh layer and pressed into the soft mass. When the putty is dry, apply finishing layer, hiding nail heads or plugs with self-tapping screws.

It is advisable not only to know what to use to glue drywall to a concrete wall, but also how to work with different adhesive mixtures.

Such knowledge is necessary in order to ensure a strong and high-quality joining of two planes:

• Finishing of the premises should begin after completion of all electrical wiring work.
• Lime plaster should be removed before attaching drywall to a concrete wall.
• Installation should be carried out only on a solid supporting base without signs of delamination or crumbling.
• Additionally, use dowels to secure the sheets. It is advisable to take 4-5 pieces per plate.
• Leveling walls with sheets must be carried out at a temperature of at least +10°C.
• The plasterboard slabs must first lie in the room where they will be installed.
• A 10mm gap should be left at the bottom to protect the plasterboard from moisture coming from the floor.
• If there is a level and uneven surface can be used on one wall different methods fastenings
• The adhesive composition is applied to walls made of silicate blocks, and not to the surface of the sheets.

Advice! Before gluing drywall to the wall, you need to moisten it with water from a spray bottle.
