Installation of drywall in a brick apartment with glue. What is the best drywall adhesive to use? How to glue drywall to a wall with glue if it is concrete or aerated concrete

Plasterboard sheets (GKL) have become an excellent alternative to traditional plaster since their appearance on the building materials market. Leveling the walls with drywall minimizes "wet" processes and requires significantly less time to complete the work. GKL can be glued or mounted on a special frame made of profiles - both methods are intuitive and do not differ in particular complexity of implementation. Therefore, any of them can be safely "adopted" by home craftsmen. In the same article we will talk about gluing drywall to the wall.

GKL wall pasting, in contrast to frame method allows significant savings usable area rooms, which is especially true for small rooms. On the other hand, it becomes impossible to use any insulation, so it is undesirable to glue drywall on cold and freezing walls. Both methods are perfectly combined with each other, and their combined use in one room is possible.

Depending on the initial state of the walls that require plasterboard finishing, there are three main methods for gluing sheets. Also, for reliable adhesion of the material to the base, it is necessary proper preparation surfaces. But first things first.

Preparing the surface of the walls

In order to securely stick the GKL on the wall, you need to prepare the surface in a certain way. The result depends on the preparation to no lesser extent than on compliance with the gluing technology itself.

The first step is to clean the surface of the walls from dust and other contaminants, peeling plaster. At the stage preparatory work wiring should be done. Power cables in without fail must be laid in pre-made grooves - the so-called strobes. At the installation sites electrical sockets and switches, it is necessary to make recesses for mounting socket boxes or, if you call it correctly, installation boxes.

The next step is to apply a primer. The type of primer is selected depending on the material of the walls.

To obtain the best result on surfaces with low moisture absorption, such as concrete, it is recommended to use adhesive primers of the Betokontakt type.

Next, the design position of the drywall sheets is marked. To do this, at the minimum possible distance on the floor along the wall, which will be pasted over with drywall, taking into account the thickness of the material (9.5 or 12.5 mm), a straight line is drawn. With the help of a plumb line, this line is transferred to the ceiling.

At this point, the preparation can be considered complete and proceed directly to sticking drywall sheets on the walls. I would like to immediately note that the bulk of the offers of drywall and related materials on the domestic market (about 70%) falls on the German industrial group KNAUF. Therefore, it would be logical to describe the technology using the materials of this particular manufacturer, as the most accessible and common.

We glue drywall on smooth walls

The simplest and most economical in terms of material consumption is gluing GKL on even walls. These include walls with differences in the plane of not more than 5 mm. It is recommended to use Knauf-Fugen universal gypsum putty as an adhesive. This gypsum-based putty with polymer additives has a high plasticity and can be applied in a fairly thin layer.

• At the beginning of work, drywall sheets are cut to size. In this case, it should be taken into account that between the glued sheet and the floor there should be a gap of 10-15 mm, the so-called heat-shrink seam.
• It is subsequently sealed with putty or sealant. This dimension must be taken into account when cutting.

Marking and cutting parts for installation in difficult areas irregular shape and at the junctions with the openings, it is recommended to perform after gluing the previous sheets. This method reduces the risk of errors.

• GCR is placed along the wall face down.
• Putty is applied along the perimeter and in the center of the sheet in strips approximately 130 mm wide using a notched trowel.
• If the thickness of the drywall is 12.5 mm, then one longitudinal strip in the center is sufficient; at a thickness of 9.5 mm it is recommended to apply two. On places that will subsequently be subject to stress, for example, lined with ceramic tiles, as well as adjoining, the adhesive is applied continuously.
• Next, the drywall sheet is lifted, installed on the lining and it is glued.

Pieces of drywall can be used as linings, which are subsequently removed. The design position of the sheet is achieved by pressing it against the wall with periodic control using a long level or plumb line.

It doesn't matter if the walls are uneven

The technology of gluing drywall to walls that have irregularities looks a little different than gluing to a flat surface. Moreover, depending on the degree of curvature, it is produced in two ways.

If the deviations from the plane are within two centimeters, then the GKL is no longer glued to putty, but to Knauf-Perlfix gypsum glue.

• Glue with a trowel is applied in piles with a step of 250 mm along the perimeter of the sheet and 350 mm in the center.
• Further manipulations with installation on linings and leveling repeat the previous method.

A larger amount of work will require sticking drywall sheets on walls, the irregularities of which go beyond 20 millimeters. In this case, the lining is performed in two stages and is a kind of symbiosis of the two previous methods.

1. First, a flat plane is formed from strips of drywall, cut into a width of 10 centimeters.
2. These peculiar beacons are fixed on the wall with glue applied in piles with a step of 350 mm.

The strips should be oriented on the wall in such a way that in the future they are located along the perimeter and in the center of the drywall sheets. The sheets themselves are glued to the resulting guides using Fugen putty according to the first method.

Gluing drywall to walls is a great way to level even very problematic surfaces. Due to the absence of any kind of frames used when mounting on profiles, the method allows you to achieve significant savings area of ​​the room. The availability of materials and the elementary nature of the work allows us to recommend the method even to beginners.

Many today prefer to finish interior spaces drywall. But at the same time, few people know that there is a drywall adhesive that can greatly simplify the task of installing it. About what types of adhesive solutions exist for this material and how to work with them, today's article will tell.

It is known that the most reliable fixation of drywall sheets is carried out using metal profile. But at the same time, drywall glue can be different. Installation of drywall on glue will be quick if the solution was chosen correctly, and the quality of such fastening will be in no way inferior to the metal frame.

The advantages of this installation include:

• saving space;
• saving time and money that would go to installing the frame;
• simple and fast installation.

To date, GKL sheets can be attached to the following compositions:

• Knauf Perlfix (Knauf Perlfix);
• polyurethane elastic adhesive Polymin;
• gypsum mixture Volma;
• putty Fugenfüller;
• silicone sealant (for example, Bolars).

Let's consider each type separately.

Knauf Pearlfix is ​​​​the ideal solution for installing drywall sheets on various surfaces. The features of Knauf Pearlfix include its high moisture resistance. Therefore, this adhesive is used when finishing bathrooms, kitchens, balconies and loggias. In addition, the composition of the Knauf Pearlfix mixture includes special additives - synthetic fibers. During operation, the solution is consumed sparingly. Knauf Perlfix dries for about a week, but when creating right conditions drying time can be reduced to 5 days. At the same time, Knauf Pearlfix glue is not elastic.

Polyurethane glue is sold in stores in cylinders. It is ideal for installing plasterboard sheets, as well as pasting seams when uneven walls. It can also be used to glue ceramic tiles or level the ceiling. To use such glue, a special gun is required, which ensures economical consumption solution.

Volm's gypsum mixture is the most plastic composition. Glue is used in a situation where it is necessary to install individual elements, which include gypsum. In addition, with the help gypsum mortar Volma can fix not only drywall sheets, but also foam plastic as a sound insulator or wall insulation. The composition of Volm makes it possible to easily handle the ceiling with your own hands, since it is able to take the form of any irregularities. Please note that Volma glue does not shrink after drying, while maintaining high resistance to various pathogenic microorganisms. Volma adhesive products can be used in bathrooms and other residential areas with high humidity. The material consumption here is 5 kg per 1 mm layer when applying the solution to the entire wall area.

Fugenfüller putty is used if, after installing drywall on its surface, further installation of tiles is required. The putty itself is applied pointwise, which minimizes its consumption. This type putty allows you to attach sheets of material to wood, shell rock, stone and foam blocks. The solution increases the protection of walls from the harmful effects of fungi and mold, as well as high humidity.

Silicone (tile) adhesive for drywall in its characteristics is similar to polyurethane compound, but differs from it in consistency. They process cracks, corners and joints. The solution contributes to their impermeability. With the help of such a mixture, not only the installation of plasterboards is carried out, but also wallpapering, installation of plastic and tiles, as well as any finishing materials that are light in weight.

How to glue drywall on each of the solutions listed above, will tell detailed instructions included with each mixture.

Where to use

Before asking the question "how to glue drywall", you need to find out the scope of this or that adhesive. Contrary to popular belief about its specialization, drywall adhesive is not a narrowly focused tool. Such mixtures have a fairly wide scope. Typically, adhesives of this kind are used for the following purposes:

• installation of plasterboard;
• installation mineral insulation, as well as gypsum combined panels;
• fastening of various products made of expanded polystyrene, as well as tongue-and-groove plates;
• ongoing work with decorative tiles, gypsum stucco and other gypsum products.

But in order to glue all this, you need to know how to glue drywall or any other material.

How to level a plasterboard wall with glue

Any specialist on the question "how to glue drywall" will answer that the key to success is the correct preparation of the walls. In such a situation, you can easily level the walls with adhesive.

Preparing the walls before starting the installation of GKL sheets involves the following steps:

• we remove all bumps and ledges from the walls;
• the surface is primed;
• after the first layer of primer dries, apply a second one for greater protection of the walls.

After that, you can proceed with the installation of GKL sheets. To do this, they are cut into pieces of the desired length.

Remember that when installing them, you must leave a small distance above and below. This gap will allow the glue to dry much faster.

Typically, the width of this gap is 0.5 cm at the top and 1 cm at the bottom. In this case, you need a special stand for drywall sheets so that they do not slip during drying.

Dowels can be used as limiters in this situation. For their installation, holes are drilled all over the surface of the walls. The screws should be screwed into them in such a way that their caps are all on the same level. When pressing sheets with glue to the wall, they will not allow them to sink deeper, bringing the wall to one level.

Glue is applied to the sheets from the back side in stripes along the edges and center, as well as in plentiful pieces. The step between adjacent pieces of glue should be about 20-30 cm. Remember that the applied adhesive solution does not need to be leveled. For greater convenience, it is allowed to apply glue to the walls, and not to drywall sheets.

If the walls are very curved, then you can first glue the intermediate layer of pieces of material.

How to cook

To prepare any adhesive for the installation of drywall sheets, you will need:

• dry mix;
• water;
• mixer with a special whisk attachment;
• mixing container.

The cooking process involves the following algorithm.

cladding made of drywall boards suitable for covering interior bearing walls and partitions, if during the reconstruction of the interior, the decoration is carried out in as soon as possible without plaster.

Thanks to the installation of drywall on gypsum glue, we minimize the spread of dust when grouting walls, if the walls are leveled with plaster.

The base to which the gypsum boards are glued is strong, not loose, not exposed to frost, rain and moisture.

Drywall glued to gypsum glue cannot be used to cover inclined and horizontal surfaces, ceilings.

There are two methods for installing drywall boards:

• fixing plates using gypsum adhesive mortar - more on that below;
• fastening of plates on a steel profile.

How to glue drywall on glue. Step-by-step instruction

PPreparing the wall for attaching drywall boards to the adhesive is done in two steps:

• complete concealed installation
• dust and loose material residues must be thoroughly cleaned from the wall surface

Wall priming

The surface of the wall to which the drywall is glued is primed to strengthen and even out the absorbency of the base. To do this, it is worth using a primer, which is used for priming absorbent and porous surfaces made of cellular concrete, Ceresit CT 17 or another similar in characteristics. We wait until the soil dries at least 12 hours.

Drywall preparation

Selecting 9.5mm or 12.5mm plasterboard wallboard, cut to wall height minus 15mm to leave gaps between ceiling and floor. We measure and cut holes in the plate for sockets using electric jigsaw or hand saw for drywall.

The solution is mixed with a drill and a stirrer (mixer). Do not stir the glue at idle, so as not to foam the mixture.

Glue application

We start applying glue cakes. The distance between the rows of cakes is 600 mm, and for pancakes in one row 300 mm, gypsum cakes are made with a diameter of 100-150 mm.

For window niches, gypsum adhesive is applied to the surface of the gypsum board with a spatula or notched trowel and adhered.

Gluing drywall boards

After applying the cakes, glue the plates to the wall. From below we put linings on the floor (pieces of drywall).

Surface leveling

To identify irregularities, use a long level, applying to the drywall surface. Adjustment gypsum boards from the moment of gluing to the wall is done within 25 minutes. After this period, the gypsum adhesive hardens and further interference with the structure of the cake will cause the surface of the base to peel off.

After the gypsum glue has dried, we control the further laying of the plates on the wall using a spirit level.

Seam sealing

After gluing the gypsum boards, we proceed to filling the joints between the boards, using the starting and then finishing putty gypsum, and reinforcing tape.

Completion of installation

Such a prepared surface is ready for finishing (painting, wallpapering).

Attention!

During installation, we observe constant humidity and air temperature. Works involving the release of moisture, complete or stop. Minimum temperature installation +10 °C. It is important to avoid abrupt changes, cooling or overheating of the room.

A wonderful thing - drywall, comfortable, technologically advanced, now indispensable for interior decoration. But while many people attach the GKL in the old fashioned way - to the profile, although this is not the only way to fix it in the right place. It's about sticking sheets. The quality of fastening can be in no way inferior to that produced using metal frame, but for this you need to follow the technology and choose the right glue for drywall.

Advantages of the adhesive method:

• ease of installation;
• time gain;
• saving money, which is the purchase and installation of the frame;
• increase in space - the crate would take 5–6 cm of space from each wall.

When adhesives are used for plasterboard

Cases when it is better to fix drywall sheets to surfaces with an adhesive method:

1. When leveling the main walls with the size of drops, blockages and other irregularities up to 50 mm. However, with extensive potholes, the cost is too a large number glue can exceed the cost of the metal frame and make the venture economically unprofitable.
2. When leveling the ceiling. But in this case, while the glue sets, the gypsum board must be securely fixed so that it does not collapse under its own weight. Solve the problem of dowel-screws.
3. When designing door and window slopes.

Glue can be used when fixing the second layer of drywall with a 2-layer sheathing of a frame or crate, but this is rarely practiced: using self-tapping screws in this case is faster and cheaper.

Glue for drywall: which one to choose?

• Specialized glue ("Perlfix" from the German company "Knauf", "Ceresit", Russian analogues"Volma" and "Montage").

• Plaster or putty, which is based on gypsum. In terms of price, quality of adhesion to the surface to be glued, the degree of shrinkage during setting, there is practically no significant difference with specialized adhesives for working with gypsum boards.

• Acrylic putty. It is used when subsequent tiling is planned. The composition keeps the walls from mold, harmful effects fungus and high humidity. Drywall is attached to it on a base made of wood, shell rock, stone and foam blocks.

• Polyurethane mounting adhesive in an aerosol can. An ideal material for installing plasterboard and pasting joints with curved walls. With it, you can level the ceiling, attach ceramic tiles. To work with it, you need a special gun that provides economical consumption of the solution.

• Low expansion foam replaces adhesive.

• Tile adhesive. Its mobility and fine-grained filler make the work convenient and fast.

• Sealant. Any type of sealant replaces the adhesive intended for gypsum boards, in addition, it allows you to process joints, corners, close cracks, making them impervious to moisture.

• Liquid Nails. Strong, safe for health glue, but requires time to dry and is designed for a load of up to 15 kg. It is quite suitable for sticking not the thickest drywall.

Note! The mixture for fixing GKL from Knauf requires professional skills, work must be carried out without delay, as the glue hardens quickly.

How to glue drywall on brick, gas and foam concrete

At uneven surface with wide seams, which distinguishes masonry from brick, foam and aerated concrete, it is convenient to stick sheets of drywall with gypsum glue or any other gypsum mixture. In addition to the qualitative result, the advantage is profitability: usually 5 kg of Perlfix is ​​consumed per 1 m², the price of which is 300 rubles. for a 30 kg bag.

Comparable in terms of costs with gypsum adhesive inexpensive polyurethane foam. A 750 mm balloon with spot application is enough for 8–10 m², the cost of a square is 30–40 rubles. However, here, with a large gap between the plasterboard and the wall, solving the problem of foam expansion, each sheet will have to be additionally attached with dowel screws.

Foundation preparation

Prior to the direct gluing of drywall, the surface is primed, strobes are made for electrical wiring. At brickwork serious attention is paid to the elimination of cracks and irregularities inherent in it. For this, leveling putty mixtures are used. In some cases, strips of plasterboard and mounting tape can be glued to eliminate defects.

Foam and gas blocks usually do not create similar problems, however, there are damages due to careless transportation and unloading. They are eliminated with a plaster mixture.

What adhesives are required for concrete floors

Usually monolithic walls there are no obvious irregularities, the GKL sticker on them goes smoothly and quickly. For this purpose, you can choose:

• gypsum glue for plasterboard sheets;
• gypsum putty;
• acrylic putties;
• cement adhesive for gluing tiles;
• polyurethane adhesive;
• mounting foam.

Each means with a minimum value glue line will provide a strong connection of drywall to concrete.

Flawless specifications y - primer, which includes acrylic polymers, cement, quartz filler. Its peculiarity is special additives and additives that guarantee reliable contact with the most complex and dusty surface, which is what concrete usually sins with.

Suitable materials are foam, gypsum and cement adhesives, but the thickness of the joints when using them will be greater and cause an irrational reduction in room space.

Technology for mounting GKL on glue

After the optimal adhesive mixture has been selected, it's time to move on to the GKL installation. There are 3 :

Option number 1 (for flat walls)

It is used with walls without drops (usually these are concrete or plastered surfaces).

• The walls are strobed, the cable is fixed in the grooves obtained, holes are made for sockets and switches.
• Apply to a dust-free surface. If the wall is painted and adhesive composition does not stick, the composition with quartz filler solves the problem.
• Holes for electrical equipment are cut out in the GKL.

The adhesive composition must be prepared for 1-2 sheets, especially at first, when there is no necessary skill.

• Gypsum-based glue is applied to the gypsum board with a notched trowel, the excess is removed. If another composition is used, such as polyurethane adhesive, it can be applied in stripes or as shown in the photo.

• The sheet is placed near the installation site face down.
• Before sticking, it is carefully lifted and the wires are directed into the prepared holes.
• The sheet is effortlessly applied to the wall, with the help of the rule they find places where the material should be more tightly attached to the surface, they achieve this by tapping the sheet with their hand or applying a board and lightly hitting it with a mallet. You should not knock on the level - this is an accurate tool that will fail before the floors become even.

Option number 2 (irregularities up to 2 cm)

When the wall level differences approach 2 cm, drywall should be glued in a different way, although surface preparation and plasterboard, primer, and electrical cable laying do not differ from the previous version.

• The sheet is placed on linings at the place of attachment - the beginning, as a rule, is the most protruding section of the wall surface.

Glue dots are made along the perimeter of the sheet at a distance of 25 cm from each other, inside the perimeter they are placed every 40 cm. There should not be large gaps so that the reliability of fastening does not suffer. For the same reason, it is necessary to ensure that the height of the points is greater than the wall level differences.

• Gluing begins with the output of electrical wires and a light pressure of drywall, which should simply catch on the wall. It is better to work together, so that one master constantly holds and, if necessary, helps to press the sheet.
• The final fixing is preceded by a thorough check of the plane in all directions to determine where to press the material. When flaws are identified, individual sections are knocked out, the process continues until complete satisfaction with the result.

A special option when drywall is attached to a surface of gas or foam concrete. In this case, for reliable fixation, the adhesive composition is applied not to the sheet, but to the wall, although this method requires care - when installing the GKL, it can be easily skewed.

Option number 3 (differences of more than 2 cm)

Technology for surfaces with large irregularities:

• Remove fragile areas of plaster from the ceiling.
• The walls are carefully primed.
• Lighthouses are being prepared: strips of 100 mm wide are cut out of drywall, necessary to create a flat base. These elements are placed along the perimeter of the wall and vertically after 40–60 cm. They are fixed with glue, the layer of which is adjusted taking into account level differences.

• The main sheets of drywall are glued to the beacons after the final hardening of the adhesive on the strips. They are fastened with the help of the composition that was used to create the lighthouses. The adhesive mass is applied in lines along the width of the guides, after which the sheet is lifted and pressed against the beacons. If they are aligned correctly, installation will not be difficult.

Drywall is construction material, which is most often used to level the surfaces of walls and ceilings, which after it remains even and smooth, suitable for any type of finishing materials.

The structure of the drywall sheet: 1 - plaster base, 2 - drywall plates.

Today, two methods of mounting this unique material are used: using metal or wooden frame and frameless way using glue.

The first method is considered more reliable and of high quality, but it also has some disadvantages, including an increase in cost due to the use of profiles, complexity, reduction usable space, which is especially important for apartments with low ceilings. Mounting drywall for glue does not have such disadvantages, in this case sheets are laid directly on the surface. But there are also some nuances here, for example, such a surface must be pre-prepared for laying.

Drywall, or plasterboard sheets, can be mounted in bathrooms where the humidity is quite high. Mounting simple and fast, just put your hand and arm yourself with simple tools. For greater convenience, you can invite a couple of assistants. So it will be more fun, and the work will go faster.

Frameless mounting options

Methods for mounting drywall on glue

Frameless installation of gypsum boards can be done in two ways, in the first case it is installation on the wall surface with small differences, fluctuating in the range of 1-3 cm, and the second method is laying on special beacons. Let's look at these two methods in more detail.

Do-it-yourself sticking drywall directly to the wall surface. This method is more complicated, it requires a certain skill and skills, but it does not differ in particular difficulties. The procedure is simple: first you need to clean the surface of traces of the old coating, apply markings where the GKL sheets will be located. After that, all the tools necessary for work are prepared, the sheets are cut and the adhesive solution is kneaded.

Apply glue small areas in increments of 15-20 cm (permissible up to 30 cm), they should be located along the perimeter of the plate and in the center.

If the ceiling or wall is even, that is, the slab will fit snugly, then the number of areas treated with glue will not be needed so large.

Next, the GKL sheet is attached to the surface and neatly placed in place. Using the building level, it is necessary to determine the evenness of its installation. When mounting on the ceiling, it is more convenient to use a stepladder; you definitely cannot do without an assistant.

The second method is relatively simpler, it is used when the wall or ceiling has large irregularities that are more than 3-4 cm. Here it is best to use wireframe method, but if it is impossible for a number of reasons, then installation will be carried out by beacons. To do this, in increments of 60 cm, beacons from strips of plasterboard are installed on the ceiling or wall, which will determine the level of installation. They are attached to the adhesive solution, which should harden a little, after which you can proceed with the installation of the plates.

Such an installation of GKL on beacons resembles the wireframe method, as a result, under the sheets remains free space. The disadvantage of the method is the high consumption of glue, some of which goes to beacons, the need for constant monitoring of the evenness of the surface. If you have to mount the ceiling in this way, then it is best to immediately use the frame, since the cost in this case of both methods will be the same, and the frame is easier and faster to mount.

Pros and cons of mounting on glue

Applying glue to drywall is done pointwise on all surfaces of drywall sheets

When laying with your own hands in this way, you can achieve savings, since you do not have to spend money on metal or wooden profiles, fasteners. There is also no need for pre-assembly of the frame, setting the verticality. It is enough to mark the wall, cut the sheets and mix the glue. There is another, decisive plus: such a wall is more reliable due to the fact that it does not have cavities, cracking at the joints is quite rare.

Using the adhesive method of laying drywall has not only advantages, but also disadvantages. Frameless method good to use if the surface is relatively flat, but what to do when the ceiling is completely curved, which is not uncommon in apartment buildings?

In this case, it remains only to use beacons or preliminary alignment, and this is a large consumption of materials and rather laborious work, not everyone can do it with their own hands. The frameless adhesive method is good for relatively flat walls and ceilings. Of the minuses, it should be noted that the conduct of communications under the surface and additional insulation much more difficult. For cables, you will have to ditch the walls, and the insulation will take up a certain place, and it is best to use foam, which not everyone prefers.

General adhesive mounting technology

The technology of laying drywall without a frame, but only with glue, differs in some features. In this case, not only marking the surface of the wall or ceiling is required, but also preliminary alignment. The marking itself shows where and how the sheets will be located, usually it is a grid with lines that go in steps of 60 cm. The GKL gluing technology itself provides that large, solid slabs will be mounted, without first cutting them. But in practice, it usually turns out that not whole sheets are used (the length of which reaches 3 m), but parts cut into convenient pieces.

The scheme of leveling the wall with drywall.

GKL installation is carried out in checkerboard pattern so that there are no crossing seams. The boards are glued to the surface with an adhesive that is applied around the perimeter and in the center of each sheet. But there is also one feature that must be taken into account. This is the speed at which the adhesive sets. Often for a beginner who makes such an installation with his own hands for the first time, this causes a lot of inconvenience, but everything is relatively easy to solve. The working time with a mass of glue is about half an hour, that is, do not knead a lot of the solution at once, it is better to do it gradually.

Before starting work, immediately mark the surface, cut all the sheets, prepare the tools (two spatulas, building level And so on). After that, you can already begin to knead the glue in order to immediately get to work. The most optimal amount of glue is about half a bucket. In this case, you can safely and without haste stick a large sheet. If the composition is not enough, then you can always mix it up, which is better than throwing out a bucket of already unusable, hardened glue.

The technology for mixing the composition is usually the same, but for some manufacturers it may differ slightly. Therefore, it is best to read the instructions. The consistency should resemble very thick sour cream, if it turned out too thin or thick, you can always add water or a dry mixture.

Do we apply glue on the base or sheets of GKL?

The question is how to glue drywall is also important. Many experts argue that it is best to apply glue not to GKL sheets, but to the base, but this is a rather controversial issue. Glue mixture should adhere equally well to both the material and the base. Therefore, here you can give such simple advice: apply it on the slab around the perimeter and in the center and on the surface of the wall or ceiling. When installing ceiling coverings, it is best to apply glue to the ceiling itself, otherwise the weight of the sheet will become very large and it will be difficult to lift it up. The weight of the plate is about 29 kg, and with glue - all 40 kg, so it will be difficult to lift it even with two people.

Another point to keep in mind when installing with your own hands is the primer. Before gluing, the surface of the wall or ceiling should be carefully primed to increase adhesion. The primer will fill in all possible irregularities, microcracks, which at first glance may not be noticeable, but big influence on the quality of the installation.

Today, drywall is a building material that is used for the most various works. But most often it is used to level walls, it allows you to create a perfectly smooth and even surface that can be immediately painted, wallpapered, laid ceramic tiles. Drywall is easy to install with your own hands, for this there is no need to have special knowledge or buy an expensive tool.

Moisture resistant drywall is a modern finishing material. It is endowed with excellent quality and technical characteristics. The scope of its application is quite diverse.

Advantages

GKLV environmentally friendly: does not harm human health. This makes it possible to use it in the decoration of any premises. The structure of moisture-resistant GKL absorbs moisture 90% less than conventional drywall.

The difference between moisture-resistant drywall and conventional drywall is that it absorbs moisture 90% less.

It is fireproof, as it does not ignite from exposure to a direct source of fire. Sheets can be mounted in rooms with high humidity. From such an impact, they will not be deformed. The size of moisture resistant drywall can be any. This allows you to select its parameters for faster repair work.

GKL of this type are not afraid of temperature changes. Often moisture resistant drywall used for cladding the facade of the building. In this process, the most important thing is to properly treat the drywall surface with protective equipment.

In addition, GKLV is endowed with the following characteristics:

• Strength - its structure can withstand significant physical and mechanical stress.
• Practicality - the material is quite easy to mount on any base.
• Versatility - the design of its surface can be done with paints on water based.

Moisture resistant drywall is considered an excellent heat and sound insulating agent. You can clean its surface with a damp cloth, but without the use of abrasives and detergents.

Production

The technological process for the manufacture of GKLV involves the use of only pure and high-quality raw materials. Certain technical characteristics of the sheets depend on this.

The following raw materials are used in production:

• Gypsum mix.
• Pressed cardboard.
• Various supplements.

As the last ingredients, modern components are used that increase quality indicators.

These include the following:

• Waterproof solution - it does not allow moisture to penetrate into the structure and destroy it.
• Antifungal mixtures - protect the surface from the appearance of fungal diseases and mold.
• Impregnated impregnation - slows down the process of moisture absorption.

Thanks to the use of natural raw materials and all additives, GKLV drywall can be used in poorly ventilated areas.

Moisture resistant drywall is mainly used for finishing the bathroom or kitchen.

In the manufacture of the material using modern specialized equipment. Production Line has more than 10 machines. With their help, drywall is given certain parameters.

Particular attention is paid to storage technology. The immutability of technical characteristics depends on it.

GKL should be stored in a dry place with constant temperature regime. Warehouse equip additional systems ventilation so that dry and moist air masses do not affect the structure.

Types of GKLV

Today, drywall is considered the most popular material for finishing work.

Since it can be used in surface cladding in any room, manufacturers make different kinds GKLV.

How many self-tapping screws per drywall sheet may be required and calculations depending on the type of installation

Moisture resistant GKL can be of a standard type or moisture and fire resistant. The first type will be indispensable in the cladding of surfaces in the bathroom, the second - in the design of the kitchen area and the fireplace room.

According to the scope of application, the material is divided into ceiling, arched and moisture-resistant wall plasterboard.

Their parameters differ significantly from each other. Wall used for facing the surface of the wall. Ceiling is suitable for mounting simple and complex structures on the ceiling. Arches and other decorative elements are made from arched.

Specifications

During the production process, moisture-resistant drywall is given certain parameters. Also, with the help of additives and special substances, the material is endowed with quality indicators.

The size of a moisture-resistant drywall sheet depends on the established standards (GOSTs). The length of the GKLV is 2 - 4 m. The width varies between 60 - 120 cm. Such parameters allow you to calculate the exact amount of material for repair.

The finishing of moisture-resistant drywall does not differ from the usual finish, a primer and putty are used.

The weight of the sheet is not too large and is 9.7 kg / m2. This has a positive effect on the overall weight drywall construction. It does not create additional load on the rough base.

The thickness of moisture-resistant drywall depends on another material parameter. With a sheet length of 2 m, it can be like this:

• 6.5mm;
• 8 mm;
• 9.5 mm.

The weight of the GKLV also varies depending on this technical indicator.

If the length of the sheet reaches 4 m, then its thickness is 12.5 mm, 14 mm, 16 mm. These parameters do not affect the execution of facing works.

How to distinguish moisture resistant drywall from ordinary

When choosing finishing materials, you must be careful. In the market, you can often buy counterfeit goods that do not meet the standards. Its cost is quite low. It is this fact that attracts buyers.

Moisture-resistant drywall, the thickness of which can vary depending on the length of the sheet, is quite easy to distinguish from ordinary plasterboard. In its production, special cardboard is used - it is painted in a green tint. The marking is applied in blue. The cardboard sheet of ordinary GKL is gray.

There are also differences in the shade of the structure. Gypsum composition moisture resistant GKL is darker. The edges of the sheet are protected by cardboard. This prevents moisture from affecting the structure.

Features of installation of GKLV

Moisture-resistant drywall is mounted in two ways: on a frame or an adhesive solution. The first method involves the construction of a crate of metal profiles on the rough surface.

The use of an adhesive solution also has certain limitations. Do not use water-based formulations. In addition, the rough surface for mounting drywall sheets must be flat and clean.

Drywall, which is otherwise called dry plaster, has become incredibly widespread for interior decoration. Walls, slopes and ceilings are leveled with it, soundproof partitions, arches, niches are built from it.

Therefore, it will not be superfluous to talk about the pros and cons of drywall and find out if there are any restrictions on its use.

Drywall constructions

It is clear that even the highest quality materials have not only advantages, but also some disadvantages. And in order to understand whether they are suitable for the implementation of one or another design idea, you need to know which ones.

Advantages drywall

All positive traits this finishing material can be divided into two groups - technical and operational. Let's start with the first.

Excellent specifications

It's about working with drywall. Many people want to do repairs in their own home with their own hands, but not all materials are as easy to process and install as drywall.

If we talk about its merits from this point of view, then they are as follows:

• Pretty simple installation technique. Even a beginner will only need one video lesson to understand what's what.
• The low weight of the material, the possibility of its installation alone, despite large area whole sheet.

Note. Even if you need to hem the ceiling, this can be done without an assistant, using simple home-made fixtures.

• Drywall with a certain treatment (wetting with water) can be bent, creating complex structures.

After drying, the material returns to its original strength

• It is easily cut and processed, and no complicated tools are needed for this. A knife or a regular jigsaw with minimum set functions.
• This material allows you to create hollow structures for hidden gasket air ducts, electric and telephone cables, pipes. The price of such a gasket in brick and concrete walls taking into account the device, the strobe will be much higher.

All communications remain behind the cladding

• Installation of dry plaster takes less time than leveling with conventional solutions, as it does not require long drying.
• An added bonus of this "dry" leveling is the absence of dirt.
• Finally, the drywall surface lends itself to the most different types finishes from painting and wallpapering to ceramic tiling.

Advantages of operation

If we talk about leveling the walls with drywall, everyone can find the pros and cons of this method. As for the operation finished structures, then not everyone knows what they are better than plaster or cladding with other materials.

Therefore, we tell.

• Unlike wood, fiberboard, plastic, other wall and ceiling panels drywall does not burn and does not emit toxins when the air temperature rises.
• It's ecological pure material, consisting of ordinary gypsum, pasted over with paper.
• He's better than cement plaster maintains a normal indoor climate.

For reference. Drywall can absorb 15% of moisture from its own weight without losing its performance properties.

• Under drywall sheets it is possible to place not only communications, but also heat and soundproofing materials, significantly increasing the comfort of the room.

Wall insulation device

• Do not forget about the design possibilities of this material, which allows you to carry out the most different ideas, starting from niches and arches and ending with figured ceilings with hidden lighting.
