For structures using gypsum tongue-and-groove plates, general requirements are imposed in part. Tongue-and-groove partitions: types and characteristics of structures, step-by-step installation instructions

27.06.2020

Hello to all readers and visitors of the blog.
Just the other day I was considering the topic of partitions from. This was the reason for the discussion of other modern options, for example, the construction partition walls made of tongue-and-groove slabs. Moreover, I myself really like this option, and maybe I will use it in a house that.

Tongue-and-groove slabs - convenient, practical, economical construction material for quick construction of partitions

I want to ask you one question. Tell me, can two people mount a partition of 20-30 m 2 in one day? They can. If gypsum tongue-and-groove plates were used as the installation of partitions. Yes, perhaps about 2 people, I even turned down, and one can handle it. Why so sure? He erected the walls of the house from expanded clay block with his own hands, and the tongue-and-groove slab weighs a little more, at least hollow - I already held it in my hands while studying it in a construction hypermarket. But not only in this case. With my usual pedantry, I studied the issue with regards to these plates, now I will share it, and you will see for yourself. Looking ahead a little, I’ll say that despite the apparent simplicity of masonry (due to magical grooves), nevertheless, the result will be successful only if they are used correctly.

Construction of interior partitions

The most popular material in the device interior partitions in apartments or residential buildings are: brick, slag concrete, expanded clay concrete, gas silicate blocks, drywall, and today the hero of the article is becoming no less popular - gypsum tongue-and-groove slabs (GWP). The choice of the most optimal option depends on the specifics of the work. For example, they are often erected where a structural fence requires special strength and increased sound insulation. Yes, that's just, the construction of a brick partition, as well as its subsequent finishing and chasing, is a very painstaking work. But you really want to make your task easier and choose the best option, especially when you do everything in your own hands. In general, my motto in this regard is “ minimum movements, with greater efficiency". And for this you need to choose the right material and technology. And tongue-and-groove slabs fit my motto in the best way.

Construction of a partition from PGP

Structures made of expanded clay concrete, cinder concrete and inexpensive. And by the way, from gas silicate blocks, due to their size, laying is also quite fast, plus they are even lighter than tongue-and-groove plates (but at the same time less durable). But they are nevertheless require plastering. And expanded clay and cinder concrete are also not ideal in terms of environmental friendliness. In addition, all of the listed options do not have these magical grooves due to which the masonry is perfectly even. In general, when speed and ease of construction are paramount for us, and there is neither desire nor funds for, and with the condition that in the future it is not planned to hang heavily heavy interior elements on the walls (for example, a 100-liter boiler), then very good option there will be a tongue-and-groove slab.

Characteristics of tongue-and-groove plates

So what is a tongue-and-groove gypsum board and what is the technology for its production? GWP is a monolithic block with dimensions of 667 x 500 mm and a thickness of 80/100 mm with ridges and grooves along the docking and support surfaces. Its weight may vary. from 20 to 37 kg, it depends on the type of product, and thickness. The technology for the production of GWP is quite simple. A solution of gypsum and water of a certain density is filled into a special "gypsum cooker", where the water gradually evaporates and the solution thickens. Further, the resulting mass is poured into molds and sent to the drying chamber, where, by the reaction of hydration of the gypsum binder, the material solidifies.

The tongue-and-groove plates are dried. They are all so white and slender, and you just want to take them to your site, to your house)

After that, the finished plates stand for at least another day. The result is a non-hazardous environmentally friendly product. Which is odorless, does not include any toxic compounds, is characterized by increased vapor permeability and is, as it were, a regulator of the humidity regime in the room, like all products made from pure gypsum.

Gypsum tongue-and-groove boards are fire resistant. Their soundproof characteristics meet all GOST standards for interior partitions (41 dBA). Among other things, on a smooth and flat surface walls made of tongue-and-groove slabs after the construction and puttying of the joints, you can immediately glue the wallpaper, and after absolute puttying - paint.

Manufacturers, price

GWPs are produced by many firms, the leaders of which are considered to be the well-known, good old, as well as "BelGIPS", "Volma" and Peshelan gypsum plant. One of the important factors of these plates, in front of other wall building materials, is their relatively low price - 150-260 rubles a piece. Full-bodied ones are more expensive. In order not to be unfounded right now I will visit online my favorite Leroy Merlin(by the way, there is also a favorite Baucenter, but since it is not in all cities, so I bring Leroy), you see the prices in the screenshot (2019).

And by the way, they all have quite positive reviews, however, some complain a little about the geometry (slabs of the Angarsk plant). But here, as elsewhere, it depends on the manufacturer, so when buying, pay attention to this. But everyone unanimously declares - speed and ease of erection of partitions! What else do you need, strength? They are strong enough, at least stronger than the gas silicate plates that are also fashionable today. But here they are inferior to the brick, yes. But we know that there are no options in construction that are ideal in all respects in nature, there are only best options applicable to any given situation. But now it is time to discuss the pros and cons of these plates.

Pros and cons of tongue-and-groove plates

Like any building material, these plates have their pros and cons, let's see what's more.

Pros:

Do not contain toxic substances and components.
Not flammable, fireproof.
They have increased gas and vapor permeability.
Partitions from these plates are simply and quickly erected.
Simple processing (easily planed, drilled, sawn).
Front side does not need additional plastering.
After finishing the seams, the surface can be immediately tiled, wallpapered and, in some cases, painted.
Small price.

Minuses:

Not suitable for load-bearing walls/partitions.
Manufacturers propose to use only in those buildings where all shrinkage processes have already ended (in principle, this is also true for other materials).

Have you considered the pros and cons? Draw your own conclusions.

Types of tongue-and-groove plates

On the Russian markets GWPs are of two main types: standard and waterproof(hydrophobized), which include special additives that reduce moisture absorption (not higher than 5%). The former are used in rooms with a normal and dry climate (no higher than 60% humidity), the latter are preferably used in toilets, bathrooms and other “wet” rooms where the humidity regime exceeds 60%.

Note: in rooms with high humidity, manufacturers recommend the use of moisture-resistant tongue-and-groove plates. Ready-made partitions made of PGP are faced with ceramic tiles, and waterproofing is applied to the area of foreseeable exposure to moisture.

It is worth noting here that some manufacturers paint moisture-resistant boards in the manufacturing process. green color, and others apply markings confirming this. But one way or another, there is an easy way to find out which stove is in front of you, moisture resistant or not. Of course, just sprinkle water on it. If drops roll off the surface (manifestation of water-repellent properties) and are not absorbed, this is a hydrophobized board.

Among other things, both standard and moisture resistant GWPs can be full and hollow. The latter are practically in no way inferior to full-bodied ones in terms of strength, but they are 25% lighter, and besides, they are lower in price. For example, the mass of a full-bodied Volma block 667 x 500 x 80 mm weighs 26-28 kg, while the mass of an identical but hollow block is 20-22 kg. or mass Peshelanskaya a full-bodied slab of the same dimensions weighs 28-30 kg, and a hollow one - 24-26.

Installation of partitions from a hollow tongue-and-groove slab

Knowing this feature and using light slabs, it is possible to increase productivity by reducing the labor intensity of work, and at the same time reduce the load on the floor, or save, for example, on transportation by increasing the number of HWP blocks in one machine.

Installation of partitions from Knauf tongue-and-groove plates

Step by step, the entire technology of masonry / installation of GWP is presented in this way (taking into account the recommendations of the manufacturers themselves):

Installation of Knauf gypsum boards

Gypsum tongue-and-groove boards are used not only for the construction of interior partitions, but also for interior decoration exterior walls. In both cases, they start working with them only after the erection of all the enclosing and supporting structures of the building, but before laying the finishing floor.

V winter time Installation of boards can be carried out even in unheated rooms, provided that the temperature is not lower than 5 o C. Please note that the boards need acclimatization, so they must rest in the repaired room for at least 4 hours.

The construction of partitions from PGP is somewhat reminiscent of the assembly of a children's Lego constructor. An important condition for installation is to correctly combine each element and strictly observe the vertical and horizontal position of the rows of blocks. Confidence in the strength of the structure is guaranteed by mounting adhesive prepared from mixtures recommended by the manufacturer of the boards.

Note: for fastening different kind objects on tongue-and-groove partitions, a number of requirements must be observed. When hanging suspended shelves, sanitary and other appliances (weight load from 30 to 100 kg), special corrosion-resistant anchors are used that pass through the entire thickness of the walls. When hanging pictures, mirrors, small shelves with a weight load of up to 30 kg, you can use ordinary, plastic anchor dowels. If it is necessary to place various engineering communications on partitions made of PGP, or in order to increase sound insulation, it is preferable to build a double partition. In this case, the partition to which it will be attached is the first to be erected. engineering equipment or soundproof material.

To improve your understanding of the installation of tongue-and-groove plates, you can watch this video from the manufacturer himself, everything is very detailed and clear:

Mounting errors

If a partition made of these plates rattles or lets sounds through with a light blow, this indicates that some mistakes were made during their installation. For instance, size limit exceeded partitions. They should be: 4.5 x 6 m for slabs with a thickness of 100 mm and 3.6 x 6 m for slabs with a thickness of 80 mm.

Another one of possible errors – rigid connection of a partition wall with an adjacent structure(should be only with mounting glue), which is possible only in those rooms where there are no regulatory conditions for sound insulation.

And, finally, there may be such an option - the partition is poorly attached with the elastic adjoining of the plates (through the gasket). The technology of mounting tongue-and-groove blocks suggests using, in addition to glue, special staples- 100 x 120 x 20 mm. It is worth noting here that the density of the elastic cork gasket should be at least 250 kg / m 3, thickness - 5 mm. Instead of cork, you can use a pad of biomized felt with a density of at least 300 kg / m 3, also with a thickness of 5 mm. And if you did everything strictly according to the instructions, then installation errors are excluded.

Many people find it easier to see once than to read 10 times. One video is good, but two or three are better in order to better absorb the material.

And finally, applying putty on the surface of the plates:

"I worked in many places, mastered a bunch of skills. From construction to programming. And by profession - an ecologist. A few years ago I took a plot, began to actively learn construction business in theory and practice. Now the house is standing, and I am writing articles :)"

Redevelopment of an apartment is a common thing, it remains only to decide on the material and technology for the construction of new walls and partitions. We propose to pay attention to tongue-and-groove gypsum boards - a practical, affordable and versatile material.

Tongue-and-groove slabs and their scope

Tongue-and-groove slabs (PGP) are rectangular blocks of gypsum fiber 80 or 100 mm thick. The size of the plates is standard - height 500 mm, width 667 mm. To strengthen the connection between the plates, their edge is made in the form of grooves and ridges. The technology allows erecting up to 4 m2 of partitions per hour.

Standard plates are used in rooms with a normal humidity regime; for bathrooms and baths, moisture-resistant GWPs are used. The slab can be either solid or hollow with horizontal through holes with a diameter of 40 mm. A hollow slab is not only distinguished by its reduced lightness and thermal conductivity; when laying plates of one row, it is guaranteed that the holes in the cross section are aligned by at least 90%, which allows the use of cavities as technical channels for laying electrical wiring or pipes.

Preparing the installation site

GWP are universal in application and can be mounted in almost any building conditions. Due to their low weight, they do not require a foundation and can be installed directly on the screed and even on a solid wooden floor.

The only requirement for the place of construction of the partition is that the base should not have a horizontal height difference of more than 2 mm per 1 meter. If the floor in the room does not meet these requirements, then a leveling screed with a width of 20-25 cm is produced.

The surface of both the screed and the floor must be coated several times with a deep penetrating primer, then dried and cleaned. It is optimal to mount the GWP even before the plastering of the bearing walls, so the finishing coating will turn out to be more solid.

Damper pad device

To compensate for thermal expansion and settlement of the building, a tape of elastic material is laid at the junction of partitions to the floor and walls. It can be rubber, cork or silicone tape.

The base is covered with a thin layer of GWP adhesive and the tape is laid. It takes 6-8 hours to harden, after which the construction of the partition can begin.

Installation of the first row

Installation of GWP is carried out strictly in rows, starting from the bottom. The first row is basic and must be correctly oriented in space, vertically and horizontally. The most common error during installation is the "waviness" of the partition, which occurs due to a slight displacement in the grooves. To eliminate this phenomenon, when laying each slab, you need to use a rail-rule and check the general plane of the partition along it.

The first row should be laid from the corner. The place where the slab touches the floor and the wall is covered with GWP glue, then the block is installed with the ridge up and its position is leveled. It is convenient to use for moving plates rubber mallet. Be sure to fasten the first block to the wall and floor with the help of L-shaped plates, the role of which is successfully performed by direct suspensions. To use them, you need to cut off the toothed comb from the edges and bring the thickness of the plate to the width of the comb. The plates are first attached to the base using quick-mount dowels with a length of 80 mm or more, then to the slab with black self-tapping screws at least 60 mm long.

Subsequently, the plates are fastened through one: on one side to the floor, on the other - to the previous plate with a preliminary coating of the joint with a thin layer of glue and strong pressing. To control the placement of slabs according to the project, it is convenient to use lacing or a laser level. It will also not be superfluous to mark the partition on the floor and walls, indicating the places for doorways.

Construction of partitions and adjoining to load-bearing walls

The second and subsequent rows are laid with a seam offset of at least 150 mm. The plate is located strictly in the plane of the partition due to the tongue-and-groove connection. It is enough to control the horizontal level of the installation and the lateral roll. The end plates are attached to the bearing walls with L-shaped plates or reinforcing bars 8 mm thick.

To offset the joints and remove the edge of the partition, trimming the additional elements to the exact size will be required. It is best to use a regular wood saw with a thick blade and set teeth. If the partition does not adjoin another wall, its end can be made perfectly even by increasing the thickness of the adhesive in the vertical seam from 2 to 6-8 mm.

Device for doorways

The vertical edges of the openings do not need additional reinforcement. For laying slabs over an opening with a width of less than 90 cm, it is necessary to build a supporting U-shaped bar, which can be removed after the glue has dried.

Openings with a width of 90 cm or more require laying on top of a row of slabs of a carrier beam - a 40 mm board or a reinforced CD 70 mm profile. To reach one level, it is recommended to cut the slabs laid on top of the crossbar. The jumper is laid in the partition at least 50 cm on each side.

Corners and intersections of partitions

At the corners and junctions of the partitions, it is necessary to strengthen the masonry. To do this, the plates are shifted through a row, alternately blocking the joints. In places of relocation, it is necessary to remove the ridges, they are cut with a hacksaw into sections of 4-5 cm and chipped off with a chisel.

The connection can be additionally strengthened by segments of direct suspensions or welded T-shaped elements from smooth reinforcement. In any case, additional trimming of the ridge to the desired distance will be required.

Top Row Bookmark

When laying the top row, it forms the largest number waste due to cutting to the desired height. They can be glued and laid in voids, since this row of the partition does not experience a strong functional load.

Electrical wiring is usually laid in the voids of the upper row, so it is important to prevent glue from getting into the holes. To facilitate cable pulling, you can additionally drill holes or make transverse holes with a diameter of 45 mm.

When laying the top row, it is necessary to maintain a gap from the ceiling of at least 15 mm to compensate for the deflection of the ceiling during settlement. Top row also needs to be fastened to the ceiling of every second slab. Upon completion of installation, the remaining space is blown out with polyurethane foam.

Interior finishing options

At correct installation GWP curvature of the surface is no more than 4-5 mm per meter of the plane. This is an acceptable indicator for pasting walls with wallpaper. The outer corners of the partitions must be protected with a corner perforated profile, planted on the starting putty. Internal corners also putty, strengthening them with a sickle. The joints between the boards are sanded with an 80 grit abrasive mesh, then the entire surface is coated twice with a high adhesion primer.

Alignment of walls from PGP can be carried out with any finishing putty, but it will be necessary to strengthen the coating with a fiberglass mesh. Often puttying of partitions is used only to hide the seams, as a rule, the layer does not exceed 2-4 mm. Tiling can be carried out directly on the surface of the GWP with preliminary priming.

Tongue-and-groove slabs are rectangular gypsum parallelepipeds designed for the installation of internal non-bearing partitions in rooms with varying degrees of humidity. There are hollow and full-bodied versions of their execution.

Tongue-and-groove plates KNAUF

One of the most famous manufacturers of gypsum boards is the German concern KNAUF. Brand products are available in three sizes: 667x500x80, 667x500x100 and 900x300x80.

Material of tongue-and-groove plates

The basis for the production of KNAUF tongue-and-groove boards is a gypsum binder of two grades: G-4 or G-5. The material does not support combustion and does not contain toxic components, which allows its use in hospitals and kindergartens. He does not conduct electricity and resistant to drastic changes temperature regime. A high degree of vapor permeability is characteristic of all gypsum products. The material is perfectly machinable and has no specific odor.

Technical description of KNAUF plates

The KNAUF tongue-and-groove plate has the form of a rectangular parallelepiped, the design of which provides for a special high-precision tongue-and-groove connection. The finished product has the following specifications for all sizes:

Partition of tongue-and-groove plates with your own hands. Video instruction

Partitions made of KNAUF tongue-and-groove slabs are constructed according to the constructor's method, by precise connection of the groove on the supporting side and the ridge on the docking side, with gluing of the joined surfaces. The adhesive mixture can serve as glue for gluing drywall " pearlfix”, manufactured by the KNAUF concern. Installation of tongue-and-groove plates is carried out with exact observance of rows in vertical as well as horizontal planes.

Work on the construction of partitions should be carried out after the completion of the production of load-bearing elements of the room, but before laying the finishing floors. This period coincides with finishing works indoors, mainly during the cold season. Temperature in the room should not be lower than +5 °C. Humidity should be dry or normal. Before use, the plates must undergo acclimatization, that is, adapt to the conditions inside the room. To do this, they must lie down inside for at least 4 hours.

The permissible length of the partition is 6 m, and the height is 3.6 m. If it is necessary to build a longer or higher partition, it is made up of separate fragments, each of which has a separate attachment to the supporting structures using a special frame.

Tongue-and-groove slabs Volma (solid)

Solid slabs Volma - have the shape of rectangular parallelepipeds with a tongue-and-groove system, made using injection molding technology. The main purpose is to build internal partitions in rooms with three types of humidity according to SNiP II-3-79. The composition of moisture-resistant boards includes hydrophobic additives and special plasticizers. The moisture resistant version has a characteristic green color.

The plate material does not support combustion, and does not contain substances harmful to the human body. They have high sound insulation and do not have a specific smell.

Technical characteristics of Volma plates

The surface of the plate and the geometric accuracy of the structure exclude plastering work when decorating a room. The solid plate is produced in one size - 667x500x80. The weight of one plate is 28 kg.

Volma tongue-and-groove slabs (hollow)

For the construction of partitions that require a reduction in the load on the base of the floor, hollow Volma gypsum boards are provided. Their main application is the installation of indoor structures in modern panel houses. This is due to the maximum load that the floor slabs can withstand. Like their full-bodied counterparts, the plates can be standard and moisture resistant. The standard size remains the same: 667X500X80 mm. Often, a hollow slab is used for cladding outside the room. The weight of a standard hollow slab is 20 kg, moisture resistant - 22 kg. The material properties of hollow slabs are similar to their solid counterpart.

Installation of partitions from Volma plates

Installation of a partition made of Volma tongue-and-groove plates is carried out by precise alignment of grooves and ridges on parallelepipeds with their subsequent gluing. As adhesive mixture for Volma tongue-and-groove slabs, any glue is used for gluing drywall, including the one recommended by the manufacturer " Volma-montage". Installation of the partition structure is carried out in the following order:

Installation of electricians in tongue-and-groove plates

Electrical wiring in tongue-and-groove plates is carried out by laying wires in previously made strobes. The depth of the strobe laying has a limitation: it should not exceed 40 mm with a plate thickness of 80 mm, and 50 mm with a plate width of 100 mm. The wires are fixed with alabaster or drywall glue. Landing nests for undercutters should also not exceed the specified depth. Their arrangement is possible in mirror image on both sides of the partition in through hole. But in this way, the sound-absorbing properties of the structure are lost. For additional insulation of electrical wiring in tongue-and-groove plates, corrugated tubes are used.

Wall decoration from tongue-and-groove slabs

Like any other building surface, partitions made of tongue-and-groove slabs provide for all types of construction and finishing works. The advantage of such a partition is the absence of additional puttying manipulations preceding decor work. The finishing of the tongue-and-groove partition includes: painting the surface, laying ceramic tiles and natural stone and wallpapering.

Laying ceramic tiles on tongue-and-groove walls

The process of laying ceramic tiles on drywall is similar to gluing tiles on drywall:

Due to the moisture-absorbing properties of gypsum, the finished surface should not be disturbed for three days.

Pasting wallpaper on the walls of the tongue-and-groove slabs

Before gluing the wallpaper on the tongue-and-groove partition, you should carry out small finishing Painting works . This may be the application of a thin layer of finished plaster, for example, " Rotband". Or coating the surface with a layer of finishing fine-grained putty. Before applying the putty, the surface is treated with a deep penetration primer. After the putty has dried, the surface is ready for wallpapering. It is not necessary to treat the base with soil. Gluing wallpaper on partitions made of tongue-and-groove slabs is carried out according to the standard procedure, with the application of glue both on the wallpaper and on the base of the surface to be glued.

Painting walls from tongue-and-groove slabs

The tongue-and-groove plate is also painted after surface finishing fine-grained putty. After the final layer has dried, it is carefully rubbed with a fine sanding net under the light of a building lamp. This is necessary to avoid irregularities and roughness invisible to the eye. The surface to be painted should be primed and allowed to dry. After that, one or more coats of paint can be applied as needed.

Before any type of finishing of the tongue-and-groove partition, it must be thoroughly cleaned and treated with a primer.

You are doing a serious renovation of an apartment with a redevelopment or you have bought a new building with a free layout, you will definitely face the task of installing or several partitions. If you have the opportunity to hire workers, this article will help you control them, if you do the repairs yourself, in the article I will show you step by step how to install a gypsum tongue-and-groove plate (GWP) or a tongue-and-groove partition with your own.

Two ways to install the PGP partition

It is clear that any interior partition does not hang in the air, but adjoins the floor, walls and ceiling of the room. The installation of a tongue-and-groove plate according to the technology involves two types of partition installation, depending on the connection method:

1. Elastic connection (fastening). Elastic fastening involves the installation between the edges of the partition and the walls, ceiling, floor of a layer of soundproof material. Available soundproofing material is cork. It is important to understand that elastic fastening is done where the customer, that is, you, needs to improve the soundproofing qualities of the partition. No other criteria for elastic mounting There is no GWP. 2. Monolithic connection (fastening). Monolithic fastening involves direct contact of partition plates with walls, floors, ceilings through mounting adhesive.

Material for mounting partitions made of PGP (groove-and-groove plates)

For work you will need:

1. Gypsum tongue-and-groove slab (GWP). Producers: Knauf, Volma, etc. In terms of GWP, we are interested in its thickness. Plates with a thickness of 80 and 100 mm are common. The number of plates is calculated from the area of future partitions with a margin of 10% for undercuts. GWP dimensions:

667x500x80 mm for calculating 3 plates per meter: 28 kg / 1 plate.
667x500x100 mm for calculating 3 plates per meter: 37 kg / 1 plate.
900x300x80 mm for calculating 3.7 slabs per meter: 24 kg / 1 slab.

Note: If the installation of the tongue-and-groove plate is carried out in a room with normal humidity, it is bought standard plate GWP. For partitions in wet rooms, we buy a hydrophobized (moisture resistant) PGP board. Moisture resistant Knauf board is marked with a green stripe.

2. You will need mounting plaster glue. It is sold in 25 kg bags. For bathrooms, tile adhesive can be used. 3. For elastic fastening of the tongue-and-groove partition to the walls and ceiling of the room, you can buy special brackets. Such brackets are marked C2 (for 80 mm GWP) and C3 (for 100 mm GWP). You can replace the brackets with direct hangers (PP 60/125) used in the installation of plasterboard structures.

4. For elastic connection only! You need a sound deadening pad. These are strips 100-150 mm wide, best from cork. 5. If the floor is uneven, you will need a dry cement mixture for leveling the floor at the installation site of the partition.

What thickness of GWP to choose

Interroom partitions from PGP are made in one layer. Technologically, it is impossible to make a straight GWP partition higher than 3600 mm and wider than 6000 mm. In apartments, there are usually no such walls, so there are no restrictions on the use of GWP boards for apartments.

Installation of a tongue-and-groove plate in an apartment

It is necessary to choose the thickness of the plates for the partition according to its size. The larger the partition, the thinner the plate. For partitions in a new building, it is better to choose PGP 100 mm slabs. For cladding the walls of the balcony and the partition in the bathroom, 80 mm of PGP boards are enough.

Tool for installation of partition walls GGP

For work you will need the following tool:

Saw: for cutting boards;
Drill or perforator: For fixing plates and mixing mortar. Nozzle mixer for drill;
notched trowel width 200 mm;
Spatula simple: 100 and 200 mm;
Horizontal level 500 mm long and 1500-2000 mm long.
Plumb for marking partitions;
Rubber hammer for upsetting slabs;
Clean container for mixing the solution;
Clean water for mortar and tool cleaning. Rags.

Do-it-yourself installation of a tongue-and-groove plate - step by step

Prepare a place for mounting the partition. Remove debris, prime the junction of the partition.

The base of the partition must be horizontally flat. If the slope of the base is visible during the measurement, it is leveled cement mortar. After the solution has dried, it is primed.
Mark the partition on the floor, walls, and ceiling. Use a plumb line or laser level for marking.
When the partition is elastically (soundproofed) to the floor, a soundproof strip is glued to the installation site of the partition on the assembly adhesive.

PGP boards can be installed both with the groove up and with the groove down. However, for reliable adhesion, mounting with the groove up is recommended.

Therefore, at the plates of the first row, you need to cut off the comb with a saw. Do not use a power tool for cutting, the amount of gypsum dust will be unreasonably large.
Cut boards in a partition row should not be narrower than 100 mm. Therefore, before installation, make a dry installation and try on the plates in place. If the last slab in the row is less than 100mm, cut the first slab in the row.

Install the first row of tiles with adhesive. The quality of the entire partition depends on the horizontality and verticality of the first and two subsequent rows, therefore, we actively use building level for styling control.

Starting from the first row, with elastic abutment, place reinforcing corners. The corners are attached to the GWP with standard self-tapping screws. To attach the corner to the walls, we use dowels with screws.

The number of staples on one side of the partition cannot be less than 3. That is, in an apartment with ceilings of 2700, we put the staples after the first, third and fifth rows.
We look at the photo, how the mounting adhesive fits into the groove of the bottom row.
The plates are installed with a spike in the groove with glue. We upset the plate with a rubber mallet. Remove excess glue squeezed out by the top plate with a spatula.

We constantly control the horizontal rows and the verticality of the partition.

Adjacency of the GWP partition to the ceiling

The adjoining of the GWP partition to the ceiling requires a separate paragraph.

Attachment of partition to ceiling

The correct connection of the partition to the ceiling is more difficult than to the wall. The last row of GWP slabs is cut at an angle. The corner should "look" at you. The distance from the bevel to the ceiling should vary from 10 to 300 mm.

When installing the last row of GWP, the beveled void between the ceiling and the slab is filled with mounting adhesive.

Installation of the tongue-and-groove plate is completed. After installing the tongue-and-groove partition, inspect it, check the vertical level of the partition. With the remaining glue, fill, if any, the voids between the plates. Remove excess glue squeezed out of the seams.

Further, after the glue has hardened, the joints of the partition with walls and ceiling are glued with reinforced tape and puttied. The partition itself is finished along with the walls of the room, usually puttied several times. Further, according to the repair plan (paint or glue wallpaper or something else).

If there is a need for zoning a room, then one of the options for creating a partition is the use of tongue-and-groove plates.

This is a relatively new building material, which allows you to simplify the construction of the partition as much as possible its installation is quick and easy.

The specified building material has the form monolithic slabs, which have exact geometric parameters, they are connected to each other using a tongue-and-groove lock. For the manufacture of such plates, building gypsum is used, they can be regular or moisture resistant.

Since building gypsum is used to create such plates, they can "breathe", do not burn, do not emit harmful substances, do not smell, therefore they are ideal for the construction of interior partitions and decorative for.

Standard plate size 667x500x80 mm, they have area 0.333 cm2, weight about 29 kg.

To create one square meter gypsum partitions will need only 3 plates, which allows the installation of partitions simply and quickly. Unlike, you do not need to mount the frame and filler

The advantage of this material is that it turns out even and smooth surface, you just need to seal the seams and you can glue wallpaper, paint or lay tiles.

Installation

Before carrying out the installation of a partition of plates, it is necessary to check the condition of the base. It must be strong, horizontal and motionless. If the old screed does not meet these requirements, make a new one. The mounting technology is reminiscent of

The differences in the height of the base should not exceed 1 cm, if this is not done, then it is leveled.

To carry out the installation of a tongue-and-groove partition, you need to have the following tools and materials:

tongue-and-groove plates;
adhesive composition;
gaskets, they can be felt or cork;
putty;
construction mixer or drill with a special nozzle;
hacksaw;
level;
plumb;
rule;
measuring instruments;
rubber mallet;
putty knife;
wedges.

Before starting the installation of plates, base must be cleared of debris, dust, after which it is covered with a layer of primer.

The marking of the future partition can be done after the primer layer has dried.

Mark the doors, and to facilitate implementation installation work, you can pull the cord.

Marking is applied to the walls and ceiling, for which they use a plumb line and level.

Now you can prepare the solution, for this, water is drawn into the container and the dry mixture is gradually poured, everything is constantly mixed well, it is done with a mixer or a drill with a special nozzle. The composition should be infused for several minutes and you can proceed with the installation of the plates.

It is necessary to prepare the glue in small portions with the expectation that it will be enough for you for 30-40 minutes of work.

You can lay the slabs directly on the floor, then you will get a rigid mount. The adhesive is carefully applied to horizontal and vertical surfaces, on average for mounting 1m2 of wall you will need 1.5-2 kg of glue.

When using the second method, the slabs are laid on a special cork gasket, which allows increasing the sound insulation of the walls. For this use tape 7.5 cm wide, which is glued around the perimeter of the partition.

Gasket mounted on glue, its horizontalness is checked and it is necessary to give 20-30 minutes so that it is well fixed.

Laying of plates can be carried out both up and down with a groove, but it is more convenient to place it up, since it is easier to apply glue in a groove than on a ridge.

In this case, on all plates used for mounting the first row, it is necessary to remove the comb, do it with a chisel or a hacksaw, and then level the plane with a planer.

Laying slabs is carried out similarly to laying bricks or cinder blocks: glue is applied to the base, the plate is installed, upset with a rubber mallet and its horizontalness is checked. If alignment is required, wedges can be used.

During the installation of the following rows, the adhesive must be applied to both horizontal and sides so that the plates are securely connected from all sides.

The seam thickness is about 2mm, all excess glue that has come out of the plate is removed with a spatula.

For wiring, strobes are made in such partitions, and to install sockets, holes are drilled with a special nozzle installed on an electric drill.

If pipes need to be installed large diameter, then install a double wall.

Noise isolation device

Manufacturers indicate that sound insulation coefficient standard tongue-and-groove plate 80 mm thick, is 43 dB, which is a sufficient indicator to create comfortable conditions in the room.

In practice, this indicator is often lower, therefore, in order to increase the soundproofing characteristics of such a structure, it is recommended to carry out its additional soundproofing.

For this, materials with good soundproofing characteristics are used. Special membranes can be glued directly to the wall surface.

To protect the room from noise as much as possible, such membranes glue on both sides of the wall. This allows you to increase the sound insulation coefficient up to 30 dB.

If you have the ability to create wide walls, then create a double wall from the tongue-and-groove blocks and between the walls, a heater is laid, usually it is mineral wool.

This method allows you to get high soundproofing characteristics and reliably protect the room from extraneous noise.

Do-it-yourself erection of a strong and reliable gypsum partition requires experience in construction work if not, stick with it. following tips specialists:

during the installation of partitions made of gypsum boards, don't rush. Some people point out that a tongue-and-groove partition can be made in a day. It is better to let the first row freeze well, and then proceed to the installation of the next rows;
Please note that when cutting boards quite a lot of dust, so get ready to have something to clean it up;
the strength of the material allows you to hang shelves or a TV on such a wall, but they can no longer support the weight of the cabinet.

Conclusion

If the soundproofing characteristics of the wall are very important to you, then they can be increased by creating double partitions, between which insulation is laid or the wall can be covered with noise-absorbing materials.

Follow the instructions and you will be able to create your own interior partition in the house, which will have high strength and soundproofing characteristics. Or make a decorative
