Tongue blocks can you hang cabinets. Installation of partitions made of tongue-and-groove plates is a fascinating process
Tongue slabs are rectangular gypsum parallelepipeds intended for the construction of internal non-bearing partitions in rooms with varying degrees of humidity. Distinguish between hollow and full-bodied versions of their execution.
KNAUF tongue-and-groove plates
One of the most famous gypsum plaster manufacturers is the German concern KNAUF. The brand's products are available in three standard sizes: 667x500x80, 667x500x100 and 900x300x80.
Material of tongue-and-groove plates
The basis for the production of KNAUF tongue-and-groove plates is two grades of gypsum binder: G-4or D-5. The material does not support combustion and does not contain toxic components, which allows its use in hospitals and kindergartens. It does not conduct electricity and is resistant to sudden changes in temperature. A high degree of vapor permeability is characteristic of all plaster products. The material lends itself well to mechanical processing and does not have a specific smell.

Do-it-yourself partition of tongue-and-groove plates. Video instruction
Partitions made of KNAUF tongue-and-groove plates are constructed according to the constructor's method, by precisely connecting the groove on the support side and the ridge on the joint, with gluing of the abutting surfaces. The glue mixture can be used for gluing drywall " Perlfix», Manufactured by the KNAUF concern. The installation of tongue-and-groove plates is carried out with exact observance of the rows in the vertical as well as horizontal planes.
Work on the construction of partitions should be carried out after the end of the production of the load-bearing elements of the room, but before laying the finished floors. This period coincides with the interior decoration work, mainly during the cold season. Temperature in the room should not be lower than +5 ° С. Humidity should correspond to dry or normal conditions. Before use, the stoves must be acclimatized, that is, adapted to indoor conditions. To do this, they must lie 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 erect a longer or higher partition, it is composed of separate fragments, each of which has a separate fastening to the supporting structures using a special frame.
Volma tongue-and-groove slabs (solid)
Volma's solid slabs are in the form of rectangular parallelepipeds with a groove-comb system, made using injection molding technology. The main purpose is the construction of 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 are highly soundproof and odorless.

Technical characteristics of Volma plates
The surface of the slab and the geometric precision of the structure exclude plastering work when finishing the premises. The solid slab is produced in one standard size - 667x500x80. The weight of one slab is 28 kg.
Volma tongue-and-groove slabs (hollow)
For the construction of partitions requiring 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 solid counterparts, slabs 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 the standard hollow slab is 20 kg, the moisture resistant slab is 22 kg. Material properties of hollow slabs are similar to their solid counterpart. 
Installation of partitions from Volma slabs
Installation of a partition made of Volm tongue-and-groove slabs is carried out by precise alignment of grooves and ridges on parallelepipeds with their subsequent gluing. As an adhesive mixture for Volma tongue-and-groove plates, any glue for gluing drywall is used, including the one recommended by the manufacturer " Volma-montage". Installation of the partition structure is carried out in the following order:

Electrical installation in tongue-and-groove plates
The wiring in the tongue-and-groove plates is carried out by laying wires in pre-made strobes. The depth of laying the strobe has a limitation: it should not exceed 40 mm with a slab thickness of 80 mm, and 50 mm with a slab width of 100 mm. The wires are fixed with alabaster or drywall glue. The seat sockets for the undercutters must also not exceed the depth indicated. Their arrangement is possible in a mirror image on both sides of the partition into a through hole. But in this way the noise-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 construction surface, partitions made of tongue-and-groove plates provide for all types of construction and finishing works. The advantage of such a partition is the absence of additional filler manipulations preceding the decor work. The finishing of the tongue-and-groove partition includes: surface painting, laying of ceramic tiles and natural stone and wallpapering.
Laying ceramic tiles on tongue-and-groove walls
The process of laying ceramic tiles on gypsum board 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 walls made of tongue-and-groove plates
Before gluing the wallpaper to the tongue-and-groove partition, you should carry out small finishing painting works... This can be the application of a thin layer of finished plaster, for example, “ Rotband". Or covering 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. Wallpaper gluing on partitions made of tongue-and-groove plates is carried out according to the standard procedure, with the application of glue both to the wallpaper and to the base of the surface to be glued.
Painting walls made of tongue-and-groove slabs
The tongue and groove plate is also painted after finishing the surface. fine-grained putty... After the finishing layer has dried, it is carefully rubbed with a fine sanding mesh 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. Thereafter, one or more coats of paint can be applied as needed.
Before any kind of finishing of the tongue-and-groove partition, it must be thoroughly cleaned and treated with a primer.

This video shows the process of erecting a partition from Volm's hollow tongue-and-groove slabs.
(PGP) is one of the most optimal building materials for creating walls and partitions.
PGPs are a gypsum block with a groove and a ridge at their ends, thanks to which they are assembled like a Lego constructor. Using this material, you can easily build a partition up to 6m long and up to 3.6m high.
The tongue groove can be used in both dry and damp rooms. For the installation of partitions in rooms with high humidity, special moisture-resistant tongue-and-groove plates are made.
Tools and materials for the installation of a GWP partition
To install a partition made of tongue-and-groove plates, you need the following materials and tools:
- GWP conventional or moisture resistant
- primer
- assembly adhesive
- gypsum plaster
- mounting angles (straight hangers can be used)
- dowel nails and screws
- spatulas: wide, for external and internal corners
- polyurethane foam
- level
- mallet
You can buy everything necessary for the installation of partitions made of PPG from our company.
Stages of installation of a partition made of tongue-and-groove plates
1. Preparation of the base
One of the most important conditions for creating a GWP partition is a reliable and stable base... If the base has strong irregularities, it is necessary to perform a leveling layer using a self-leveling floor.
Before starting the installation, clean the floor from dust and dirt. After that, you can proceed to the installation of the partition.
2. Installation of the partition
To increase the adhesion of materials, it is necessary to process all surfaces that will be adjacent to the future partition primer... After the primer has dried, line up and mix - can be used any gypsum assembly mixture.
To increase sound insulation and prevent other negative consequences, it is better to fasten the partition to the base through an elastic porous material, for example, a cork. This stage is advisory in nature.
The tongue-and-groove plates are mounted in rows... GWP of the first row are mounted from the wall premises on the layer of the assembly mixture. The plate can be installed with the groove up or down. To obtain a high-quality design, it is necessary to check using the vertical and horizontal level of the future partition.
Before installing the next plate, apply a layer of adhesive to the already installed tongue-and-groove plate and base. After installing the second and subsequent slabs, level them with a mallet to obtain an even structure.
As a rule, it is necessary to use not a whole GWP slab to complete the partition. There is nothing wrong with that, because thanks to the voids, the material is very easy to saw with a hacksaw.
When laying the second and subsequent rows, you need to observe the spacing of the vertical joints at least 10 cm, thanks to this, the structure is more durable.
Constantly control the width of horizontal and vertical seams in order to exclude additional alignment steps when finishing the partition from the PPG, it should be minimal.
Slabs necessaryfasten to walls and bases: they are performed using fastening angles, dowel nails and self-tapping screws.
The last row must be installed with a gap not less than 1.5 cm from the floor slab, the remaining gap is filled with polyurethane foam, after cleaning the excess, it is necessary to putty the seam with gypsum putty.
3.Finishing of the GWP partition
First of all, it is necessary to protect the external corners of the resulting partition from mechanical damage, for this it is used corner perforated profile 31 * 31. Internal corners are reinforced with reinforcing tape.
A leveling layer of plaster putty must be applied to all corners.
For laying electrical wires or wiring accessories, you can use structural cavities, which must be further expanded with a drill with a crown. With the same tool, it is necessary to prepare external holes for wiring accessories and wiring output.
Before applying a decorative coating: wallpaper or paint, it is necessary to clean the seams and treat them and all irregularities with gypsum putty and prime the surface.
The video also reflects the moments of soundproofing partitions and the installation of attachments: shelves, plumbing.
Advantages of tongue-and-groove slabs: 
- ease of assembly
- simplicity of the device of openings
- minimal finishing
- does not require plastering
- low price
- high fire resistance rates
There are quite a lot of building materials for the construction of interior partitions. But not all of them are suitable for use in multi-storey buildings. Partitions should be as light as possible in order to minimize additional stress on the building's supporting structures. Thus, the choice is narrowed down to masonry materials such as tongue-and-groove slabs and blocks.
The construction of partitions inside an already finished housing has a certain specificity. It will be necessary not only to accurately mark the place of construction of the additional wall, but also to prepare a base for it, create a vibration-damping layer at the junction points, provide for fastening the blocks to the walls, and correctly organize doorways or arches. Perfect geometry and impeccable quality of masonry will be provided by the craftsmen of Remont Prestige. They have to solve the problem of erecting partitions from tongue-and-groove slabs and blocks at almost every facility where redevelopment of premises is envisaged, and they have mastered the technology perfectly. In favor of concluding a contract with our company, to the tight deadlines and excellent quality, you can add very affordable prices for this type of work.
Price list for works on the installation of partitions from tongue-and-groove plates
Unlike the “flying brigades”, the “Repair-Prestige” company does not disappear anywhere after the commissioning of the object. We have been on the market for almost 10 years now, and our long-term warranty allows our customers to have no worries about problems that may arise during the operation of partitions, which, however, is unlikely.
Blocks or tongue-and-groove plates?
First of all, it is worth deciding which material to build partitions from - from gypsum blocks or from tongue-and-groove slabs. From the point of view of composition, they are identical, but they have different shapes, due to which the technologies for their installation, operational characteristics and the cost of partitions differ.
A gypsum block is a regular parallelepiped with straight edges and right angles. The ideal geometry of the products is achieved thanks to a special production technology, which does not use high-temperature processing. The blocks have high strength characteristics and excellent thermal conductivity.
A tongue-and-groove plate is the same block with a thickness of 8 to 10 cm, but equipped with grooves and ridges for joining between structural elements during installation. The dimensions of the slabs used for the construction of interior partitions are usually 66.7 x 50 cm. Due to the comb-to-groove joining, the partitions are absolutely even, the displacement of the plates relative to each other is an extremely rare phenomenon.
A partition made of blocks will be somewhat cheaper than from tongue-and-groove plates, the cost of which is higher. And this is only in the case when the installation will be undertaken by professionals who are able to accurately position the blocks along the planes, fix them without distortions and excessive consumption of the adhesive mixture. Such a wall is, moreover, thicker, which means that the sound insulation will be higher. The downside is that the partition will be heavier due to the thickness of the blocks (alternatively, you can use hollow blocks). A wall made of tongue-and-groove slabs will cost more, but its construction does not require a perfect eye and high professional skills.
Preparation for the construction of the partition
First of all, it is necessary to mark the walls and floor using a laser level, marking the boundaries of the new structure. High-quality installation of partitions is possible only on a carefully prepared horizontal surface. Therefore, you should start by cleaning the place where the wall was erected. Before pouring the site under blocks or slabs, the base is treated with a primer for concrete (acrylic, concrete contact or other composition of a similar purpose). It is recommended to apply two layers (the second - after the first has dried).
Even with concrete floors, they may deviate from the horizontal plane. Therefore, the surface is checked for level. Differences over 3 mm are leveled with cement mortar. A thin platform can be poured with a self-leveling mixture, setting a semblance of formwork and using a roller with needles to evenly distribute the composition. Significant differences are eliminated using a semi-dry screed. Prepare it by mixing cement 500 and fine sieved sand in a ratio of 1: 3, adding water until a wet mass is obtained. The mass is spread on a prepared base and checked by level. After drying (1-2 days), the finished site is treated with a primer, like the floor slab.
To compensate for thermal expansion and vibrations, a cork substrate (thickness 4 mm, width 150 mm) is mounted on the walls and floor at the points of contact with blocks (slabs). This damper tape can be installed with the same adhesive on which the boards will be mounted.

Partition masonry
The laying of slabs and blocks is carried out in a ragged manner, moving away from the coincidence of vertical seams by at least 1/3 of the length of the product. The first row of blocks is placed directly on the prepared site. The slabs are placed with the groove up, before installing the first row, the ridge is cut off. Using a spatula, glue or mortar is spread on the tape (for the first row and blocks adjacent to the wall), then on the block itself. The landing of structural elements is achieved by tapping with a hammer through a block or a special hammer with a rubber pad. The excess adhesive squeezed out at the same time is removed.
Every second row and every second slab (block) of the first row is attached to the walls and floor, respectively, by means of perforated metal corners. For fastening to blocks and slabs, self-tapping screws are used for wood, for walls and floors - dowel screws or anchors. The gap between the top row and the ceiling is foamed and leveled.
Interior wall partitions, in most cases, are not load-bearing structures in the house. They must have sufficient strength and good sound insulation properties. The design of the partition should easily withstand intra-building communications and hinged furniture.
In this article we will talk about tongue-and-groove gypsum (gypsum) slabs (GWP). This material is used to create interroom and interroom partitions. With a competent approach to the construction of partitions from tongue-and-groove gypsum boards (GWP) will meet the requirements listed above. But you need to focus on correct installation of tongue-and-groove slabs!
If you neglect to adhere to the construction technology, then the installation of tongue-and-groove partitions will end in the fact that instead of a solid monolith, the builder will have a wobbly and uneven wall, ready to collapse at any moment.
Kruchenkov User FORUMHOUSE, Moscow.
At home I have a partition in the bathroom made of tongue-and-groove plates. Apparently, when a hole was made in it for a sewer pipe, something went wrong. Now, if you shake this structure by the rib with your hand, you can hear how the blocks knock against each other.
There are tons of examples like this on FORUMHOUSE. And if the partition was initially folded in spite of the existing technology, then defects can be corrected only by completely destroying the structure.
But do not be alarmed, because the technology of building wall partitions from GWP is quite simple. And if you treat it with due attention, then the impression of the work done will be very positive.
AlexDo FORUMHOUSE user
I've worked at a construction site. The buildings of the old fund were reconstructed. So, all partitions were made of gypsum tongue-and-groove slabs, the work is a pleasure. As a partition - the very thing. Easy and quick to fit. The walls are flat. After filling, they are ready even for painting, even for wallpaper. The fasteners in the plate hold well. Noise isolation is also normal. But if anything, you can make a crate, lay mineral wool and trim it with a clapboard or panels.
A little about the practicality of GWP
Plasterboard manufacturers ensure that this material provides reliable anchorage to standard elements of modern interiors. This means that GKL partitions can withstand loads comparable to those on walls made of other typical materials. Hanging cabinets, household appliances, stretch ceilings - all this can be easily mounted on a tongue-and-groove plaster partition. It is possible to expand the functionality of the GWP wall partition by installing metal-plastic water pipes (no more than 16 mm in diameter) and electrical wiring elements into its body.

And you can also put doors in the groove-comb without extras, lay an electrician without problems, and hang shelves and TVs more reliably.
Tongue plates - what is it
Standard GWPs are of two types: corpulent and hollow. The construction of solid slabs is more durable, but this material is significantly heavier than its hollow counterpart. For this reason, it is not recommended
use as part of partitions mounted on floors with
wooden logs.
Hollow GWP provide high sound insulation (43 dB) without overloading the floor structure. Some people believe that all kinds of insect pests can live and multiply intensively in the interior of hollow slabs. But this opinion has not yet found serious confirmation.
Conventional (solid and hollow) tongue-and-groove slabs are used for partitions or wall cladding in rooms with dry and normal humidity levels. If the partition is planned to be installed in a room with a high level of humidity, then preference should be given to moisture-resistant plates, which have a peculiar greenish tint. Keep in mind that these GWPs are slightly heavier than regular full-bodied items.
Preparatory work
List of tools for working with tongue-and-groove plates:
- Marking cord:
- A hacksaw with a wide blade and a large tooth;
- Roulette;
- Putty knife;
- Drill with a nozzle for mixing mixtures;
- Bucket;
- Building level and plumb line;
- Rubber mallet;
- Square;
- Screwdriver.
In accordance with the recommendations of the manufacturers, the length of the GWP wall partition should not exceed 6 m. The maximum structure height is 3.5 m. An increase in these parameters is possible, but the maximum strength of the partition is ensured only if the specified dimensions are observed.
The base for the wall from the tongue-and-groove plate must be flat, stable and completely free of dust. If the floor is concrete, and there are drops on it exceeding 3 mm, then it must be leveled before starting installation work; create an alignment layer. For this, a mortar based on sand and cement is suitable (mortar grade - not lower than M50).
Aligning the GWP wall.
The solution is applied to a clean, damp floor. To obtain an ideal surface, you can create a kind of formwork and fill it with mortar clearly along a horizontal level. After complete drying, the base must be coated with a concrete primer.
If you can do without the leveling layer, then the base for the future partition, as well as the places where the partition adjoins the enclosing walls in 2 layers, are covered with a primer.
If the partition is mounted on a wooden floor, then the base must be reinforced with a strong, even beam.
Kirill147 FORUMHOUSE user
According to the technology, gypsum tongue-and-groove panels require an even base - a screed or a separate non-bending bar under the partition.
When the base is ready, you can mark out the locations of the partitions and doorways. This is done using lacing, plumb line and level.
Installation of GWP can be performed at temperatures from -10 to + 30 ° С. The building material must be brought into the room in advance. This will help him "get used" to the desired temperature regime and insure the partition from deformation (when the temperature changes, the plates may slightly change their volume).
Installing the elastic seal
In order for temperature drops and deformation of the building's bearing elements to not lead to the destruction of the partition over time, the GWP structure should be isolated from the base and adjacent walls with a special elastic (damping) tape. Damper tape for GWP protects the wall from mechanical damage and increases the soundproofing qualities of the partition. The elastic tape is a special cork backing (at least 75 mm wide), which we will glue to the base and walls in accordance with the made markings. Plates and tape are fixed with the same assembly adhesive.
Consumables intended for installation work (building mixtures, gaskets, dowels, suspensions, etc.) should be selected based on the recommendations of the GWP manufacturer. At negative temperatures, the installation of the GWP is carried out using a frost-resistant adhesive gypsum mixture.
Glue is applied with a spatula to the prepared surface in a thin layer. The tape is rolled out from above and lightly pressed with your hands. The glue sets within one hour. After this period, you can start building the partition.
Installation of GWP
The damper gasket for the tongue-and-groove plates is covered with a layer of assembly glue, on which the lower, first row of the GWP is laid. The slab can be positioned with the groove up or the groove down - this is not essential. But if the groove is at the bottom, then the ridge does not have to be sawed off so that the plate becomes even. It is allowed to install the upper row of plates vertically (if this becomes necessary due to material savings).
During the laying of the first row, the vertical groove of the tongue-and-groove plate and the base of the floor are coated with glue. Particular attention should be paid to maintaining the vertical and horizontal levels. Slabs should be planted with a mallet.
The thickness of vertical and horizontal joints should not exceed 2 mm. After installing the next plate in its place, remove the excess glue at its joints with a spatula.
Filling elements for filling the gaps between solid slabs, walls and openings are easily cut out of PPG using a hacksaw.
The relative displacement of vertical seams in the masonry of the PGT should be at least 10 cm. This is a prerequisite for ensuring the strength of the structure.
At the intersection of two partitions made of gypsum tongue-and-groove plates, as well as in the corners, the plates are laid in such a way that their joints overlap each other. Tongue-and-groove elements that interfere with the correct dressing device should be cut off with a hacksaw.
After the partition is ready, its outer corners must be reinforced with a perforated metal profile and putty.
It is often asked whether it is necessary to glue tongue-and-groove partitions with a serpyanka. Yes, the inner corners are glued with a serpentine and coated with putty.
Fastening the partition to the wall
The strength of the abutment of the tongue-and-groove partition to the walls and the base is ensured by the installation of additional elements: mounting angles, fittings or suspensions. It is more convenient to use brackets or hangers. After all, they are attached to the slab using ordinary self-tapping screws, and to the walls - using dowels. Slabs of the 1st, 3rd, and 5th rows are attached to the side walls. It is possible more often, but there should be several (at least three) mounts. A solid base abutment is created for every second slab.
During installation, straight hangers can be installed directly into the groove of the plate, having previously cut them to the required dimensions.
A technological gap of at least 1.5 cm is required between the upper row of masonry and the ceiling of the room. It must be left and covered with polyurethane foam. After drying, the excess foam must be cut off, and the seam must be putty. Between the top row and the overlap, additional fasteners are installed at the same frequency as below.
Creating doorways
For the device of door or window openings, the width of which does not exceed 90 cm, you can make masonry without additional reinforcement. In this case, an auxiliary structure made of wooden beams is mounted above the opening, which is removed after the plates of the upper row are laid and the assembly glue is set.
If the width of the opening exceeds 90 cm, then a wooden or metal lintel should be installed above it. The ends of the lintel should protrude 50 cm from each side of the opening. This will ensure an even distribution of the load on the partition.
The door (window) frame is attached to the partition using frame dowels and mounting foam.
Inter-apartment partitions from GWP
Interroom partitions made of PPG, in contrast to interroom partitions, are made double. A technological gap of 4 cm is left between the slabs. First, one partition is erected, then the second. In order to enhance sound insulation, the space between the slabs is filled with soundproofing material, mineral wool, etc.
Installation of communications
The design of the partitions made of PPG allows the installation of hidden wiring. The gypsum boards are strong enough to make vertical grooves and thick enough to accommodate junction boxes. Technological cavities inside hollow GWP can be used as horizontal grooves.
If the channel chosen for laying the wire is expanded with a crown with a diameter of 45 mm, then the cable will pass through it without difficulty. The main thing is not to block the side hole of the plate with glue during installation work.
To make it easier to pass the wire through the horizontal channels, blind mounting holes can be made in the side surface of the partition.
Some people doubt the safety of vertical slitting of gypsum walls. But, according to manufacturers (and the builders themselves), there is nothing to be afraid of.
If there is a need for zoning a room, then one of the options for creating a partition is to use tongue-and-groove slabs.
It is a relatively new building material that allows you to simplify the construction of the partition as much as possible, its installation is simple and quick.
The specified building material has the form of monolithic slabs, which have precise geometric parameters, they are connected to each other using a tongue-and-groove lock. For the manufacture of such plates, gypsum is used, they can be normal or moisture resistant.
Since building plaster is used to create such slabs, they can "breathe", do not burn, do not emit harmful substances, do not have a smell, therefore they are ideal for the construction of interior partitions and decorative ones.
Standard slab size 667x500x80 mm, they have area 0.333 cm2, weight about 29 kg.
To create one square meter of gypsum partition, only 3 plates are needed, which makes installation of partitions simple and quick. Unlike, you do not need to mount the frame and fillerThe advantage of this material is that a flat and smooth surface is obtained, you just need to close up the seams and you can glue wallpaper, paint or lay tiles.
Installation
Before installing the slab partition, 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, a new one is made. The mounting technology reminds
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 attachment;
- hacksaw;
- level;
- plumb line;
- rule;
- measuring instruments;
- rubber hammer;
- putty knife;
- wedges.
Before starting the installation of plates, the base must be cleaned 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.
Celebrate the doors, and to facilitate the installation work, you can pull the cord.
The markings are applied to the walls and ceiling, for which they use a plumb line and a level.
Now you can prepare the solution, for this, water is collected in the container and the dry mixture is gradually poured, everything is constantly mixed well, they do it with a mixer or a drill with a special nozzle. 
The composition should be infused for several minutes and you can start installing the plates.
It is necessary to prepare the glue in small portions so that you have enough of it for 30-40 minutes of work.
You can lay the slabs directly on the floor, then you get a rigid mount. The glue is gently applied to horizontal and vertical surfaces, on average for the installation of 1m2 of the 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 makes it possible to increase the sound insulation of the walls. For this use tape 7.5 cm wide, which is glued along the perimeter of the partition.
The gasket is mounted on glue, its horizontal position is checked and it is necessary to give 20-30 minutes for it to fix well.
Plates can be laid both up and down with a groove, but it is more convenient to place it up, since the glue is easier to apply into the groove than onto the ridge.
In this case, on all plates used for mounting the first row, it is necessary to remove the comb, do this with a chisel or hacksaw, and then level the plane with a plane.
Slabs are laid in the same way as brick or cinder block: glue is applied to the base, the plate is installed, upset with a rubber hammer and its horizontal position is checked. When alignment is required, wedges can be used.
During the installation of the next rows, glue must be applied both on the horizontal and on the sides so that the boards are securely connected on all sides. 
The seam thickness is about 2mm, all excess glue that has protruded beyond the plate is removed with a spatula.
For conducting wiring, in such partitions, grooves are made, and to install the sockets, holes are drilled with a special nozzle installed on an electric drill.
If it is necessary to install large diameter pipes, then mount a double partition.
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 sound insulation characteristics of such a structure, it is recommended to carry out additional sound insulation.
For this, materials are used that have good sound insulation characteristics. Special membranes can be glued directly to the wall surface.
To maximally protect the room from noise, such membranes glued 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 partition insulation is laid from tongue-and-groove blocks and between the walls, usually mineral wool.
This method allows you to get high sound insulation characteristics and reliably protect the room from extraneous noise.
Do-it-yourself construction of a strong and reliable plaster partition requires experience in construction work, if not, follow the following expert advice:
- during the installation of plasterboard partitions, 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;
- note that when cutting the slabs a lot of dust is generated, so get ready to have something to clean it up;
