Today there is a wide variety building materials, from which you can make high-quality and durable partitions in an apartment or private house. But often the choice of a specific material depends on the type of structure of the building. If the floor is reinforced concrete slabs between floors, then it is important to make interior partitions as light as possible.

The most optimal materials from which interior partitions can be made are lightweight ones, but today masonry materials such as gypsum block and foam block are of considerable interest. Various blocks are a new means for quickly and inexpensively constructing partitions in an apartment or private house, however, during the work, nuances arise that must be observed without fail. First of all, let's look at how to lay gypsum blocks on the solution.

Choosing glue or solution

First of all, let's find out what solution is needed for laying gypsum blocks. If there is money for a special acrylic glue on gypsum base is not enough, since it is quite expensive, it can be used regular glue for tiles or cement mortar in a ratio of 1:3 and add PVA glue to it. When thoroughly mixed, a very elastic and finely dispersed mixture is obtained, which is easily spread with a spatula. Its excess is squeezed out when the block is installed in place. The solution is much easier to work with because its setting speed is much slower than gypsum adhesive, which can only be worked with during the first 60 minutes.

The question often arises: “How to lay gypsum blocks with glue?” when the need arises to build a partition. In fact, the glue is the best remedy for the construction of partitions from gypsum blocks. It hardens faster, which allows you to carry out in just one day complete installation with all necessary communications. And within an hour the surface can be easily cleaned by anyone mechanically, but this is usually not required if you used tongue-and-groove slabs.

Slabs or block

Before starting to describe the technology for constructing a partition, you should decide on the choice of material type and its advantages. A gypsum wall block is, as a rule, a perfectly rectilinear parallelepiped on all sides made from a mixture of gypsum, cement and plasticizer. Good geometric parameters each product is acquired through production technology without the use high temperatures, as, for example, in the production of foam-gas-silicate blocks. But at the same time, gypsum blocks have better thermal conductivity and strength. High thermal insulation properties of the material were achieved through the use of sawdust, they also strengthen the structure of the block.

Good strength indicators made it possible to produce tongue-and-groove slabs, that is, blocks 8-10 cm thick and dimensions 66.7 x 50 cm with a groove and tongue for joining each other during installation. This is the main difference between slabs and blocks.

Gypsum tongue-and-groove partitions turn out to be perfectly smooth on both sides and during the installation process there is a low probability of curvature from the level even by a millimeter.

If we compare the price parameters, then laying partitions from tongue-and-groove slabs will cost a little more, because their cost is higher than the blocks. But one cannot fail to notice the advantages of working with them. The ridge fits securely into the groove and at the same time forms a high-quality connection of all the blocks with each other without the slightest deviation along any planes.

Although laying gypsum blocks will be cheaper, it will require more adhesive mixture. It is more difficult to align it on planes, which is fraught with curvature and distortions. The main thing in technology is compliance with the levels, so the wall made from the block turns out smooth and of high quality. But you should take into account the advantage - a wall made of gypsum blocks, as a rule, is thicker and has best characteristics strength and sound insulation. As for weight, of course, it is heavier, so hollow gypsum blocks can be used as an alternative.

Gypsum block installation technology


There are several technologies for laying gypsum blocks. Some people prefer to use glue, while others prefer to use a solution. In fact, you can use both methods, but you will only need to meet certain conditions. Before considering how to lay gypsum blocks on one or another means, you should familiarize yourself with general technology execution full complex works

To make it clearer how to lay gypsum blocks, see the photo below.

Interior partitions made of tongue-and-groove slabs must be smooth and durable. And to achieve this, it is necessary to follow the installation technology.

In order for the installation of the tongue-and-groove partition to be of high quality, it is necessary to allow the blocks to get used to the temperature at which they will be placed in place. To do this, it is recommended to bring all the material into the room and give it at least 1 day to get used to it. The block, due to the filler in the form of sawdust and plasticizer, expands slightly with increasing temperature, taking on its final shape. Compliance with this condition will eliminate the possibility of cracks occurring the next day after installation of the blocks.

The first step is to mark the location where the partition will be installed. Here you can use either a regular tape measure, a plumb line and a long level, or a laser device. When performing large-scale work, it is advisable and much more efficient to use a laser level.

Well, at home, when there is nowhere and there is no need to rush, it is quite possible to get by with familiar tools. A tongue-and-groove partition, as a rule, is perfectly flat on all sides, so no plaster or plasterboard is required. Unless, of course, you need it additional insulation. Therefore, when marking, the craftsman takes this into account and deviates from the original line a distance equal to the thickness of the additional finishing.


Installation of tongue-and-groove partitions should be carried out only on a high-quality and conscientiously prepared surface. Therefore, using a broom, brush and other tools, we carefully sweep the area where the partition will be installed. Also, the installation of partitions made of tongue-and-groove slabs provides for a perfectly flat surface. To obtain this purified mechanically the place is treated with concrete contact (acrylic or any other primer for concrete). It is recommended to do this in two layers for better adhesion of the leveling layer.

If the house has reinforced concrete floors, this does not mean that the surface is perfectly flat. In order to correctly lay gypsum blocks, deviations should not exceed more than 3 mm; in other cases, the surface must be leveled.

If the leveling layer turns out to be very thin, then a self-leveling mixture can be used. To do this, you need to install something like formwork and fill it with mortar, using a special roller with needles to roll out the mortar evenly over the entire plane.

If a tongue-and-groove partition is installed on an excessively curved surface, it can be leveled using a semi-dry screed. To do this, mix grade 500 cement and sand sifted through a fine sieve in a ratio of 1:3. Next, water is added and the solution is mixed until a uniformly moist (not wet) mixture is obtained. The process should not be described further, because it is not from this topic. After leveling with a semi-dry screed and completely drying (1-2 days), the surface must be treated again with soil (concrete contact). That's it, the surface is ready, you can start installation.

It is necessary to ensure that the partition made of tongue-and-groove slabs does not vibrate or resonate, thereby increasing the soundproofing properties of the room. To do this, it is necessary to provide a damping layer at the point of contact with the floor and wall. To accomplish this, you can use a cork backing tape 15 cm wide and 4 mm thick. It will compensate for all kinds of fluctuations and the degree of expansion of the partition when the temperature changes.

The tape can be installed using the same glue as the boards themselves. To do this, a certain amount of it is diluted; it is better not to mix it with water, because it will still become unusable even before laying the blocks. Using a spatula, spread a thin layer onto the prepared surface, carefully roll out the tape and press it to the base. You need to let the glue harden for at least 1 hour.

That’s it, the damping layer is ready, you can install tongue-and-groove slabs for partitions.

For better orientation relative to the level, you can use physical slats, that is, attach the guides to the wall and floor on both sides of the partition with dowels. This will minimize the likelihood of deviation during installation.

At the next stage, we will look at how to correctly lay gypsum blocks. For more reliable fastening of the slabs to each other and a better geometry of the wall, the slabs must be laid with the groove up. To do this, using the usual hand hacksaw The lower ridge is carefully removed. Here it is important to leave the surface perfectly flat, without protrusions, so that it fits tightly onto the damper substrate.

The mortar for laying gypsum blocks or glue should be spread using a spatula directly onto the tape and then onto the blocks. A little is required, because when joining, the excess will still be squeezed out by the weight of the slab.

Shrinking of each plate is carried out using a hammer with a rubber pad or through a block until the surfaces are in complete contact.


The tongue-and-groove slabs must be laid in a checkerboard pattern or with each row offset relative to each other by no less than 1/3 of its width. This will make the partition very durable and resistant to any impact.

The installation of tongue-and-groove partitions necessarily includes its fastening to the wall and floor using perforated corners. It can be attached to blocks with ordinary wood screws, to the floor and walls using dowels or anchors. Fastening should be done at least every other row or block in a row.
The video attached below will be an excellent instruction and clarification for the article.

Doorways in the partitions of their tongue-and-groove slabs

Installing a partition made of tongue-and-groove slabs cannot do without door or window openings. Moreover, if the height of the partition is no more than 3 m and only 1 row of slabs will be laid over an opening up to 80 cm wide, then lintels do not need to be used. It is enough to make a small half-frame with the width of the opening from wooden blocks and attach it to the slabs with self-tapping screws. Next, the next row of blocks is laid with periodic quality control of the surfaces using a level.

The use of tongue-and-groove slabs for the construction of partitions in a house is the best solution for beginners. Light weight, convenient sizes, a strong locking connection makes it possible to re-equip the room to your liking without much effort. Using tongue-and-groove slabs, you can do the installation yourself in a matter of hours. But first you should study the technology of their installation and the basic properties of the material.

Tongue-and-groove slabs are made of gypsum and silicate. The first ones pour out building gypsum with an admixture of plasticizing additives. To make the latter, quicklime and quartz sand are used, the mixture of which is pressed and kept in an autoclave. Gypsum boards retain heat better and do not allow sound to pass through, but silicate boards can withstand higher mechanical loads and absorb less moisture. Both types of slabs are environmentally friendly, so they are excellent for residential premises. In addition, these materials do not burn and do not emit harmful substances, do not rot or deform.

The slabs are divided into solid and hollow, which reduce the weight of the masonry by almost 25%. The dimensions of the gypsum board are 500x667x80 mm, the silicate board is slightly smaller - 250x500x70 mm. Installation of partitions from such slabs is carried out after completion of all construction load-bearing structures, but before the start finishing works and laying the finished floor.

Technology and installation features

Masonry made from tongue-and-groove slabs retains heat well, so it can be mounted not only in the middle of the room, but also close to a wall facing a cold room or outside the building. Double partitions help hide wiring and other communications. To divide the interior into zones, partitions with a height of 80 cm or more are installed.

Tools and materials required for installation:

  • tongue-and-groove slabs;
  • building level;
  • cement-sand mortar;
  • adhesive composition;
  • brackets for fastening;
  • anchor dowels or screws;
  • felt seal;
  • gypsum mortar;
  • primer;
  • putty knife;
  • hacksaw;
  • screwdriver;
  • rubber mallet.

Step 1. Preparing the site

If the partition is installed in a new house before finishing work begins, it is necessary to check the evenness of the floor and walls where the tongue-and-groove slabs meet. Any defects should be removed: sagging is removed by grinding, and depressions and cracks are sealed with cement-sand mortar. After drying, the walls and floor are covered with primer.

If there is a need to install a partition during an ongoing repair, the lines where the partition fits are marked on the walls and floor. Then carefully cut finishing coat according to the markings and remove to the base. You cannot attach slabs to wallpaper, paint, or decorative plaster, just like linoleum, parquet, or laminate. If the wall or floor is tiled ceramic tiles, and the coating holds very firmly, you don’t have to remove it.

To ensure that the partition is even over the entire area, a cord is pulled between the walls along the markings at a height of 30 cm from the floor. This makes it much more convenient to control the vertical position of the slabs. Now, along the line of contact of the partition to the base, glue special seal. Its width should correspond to the thickness of the slab - 8 cm. Use as a sealant cork backing or bitumen-impregnated felt.

Step 2: Installing the first row

The lower ridges of the slabs of the first row are cut off with a hacksaw. Glue is applied to the top of the seal in small portions, both on the vertical and horizontal parts. Take the first slab and, on the side that will be adjacent to the wall, insert a perforated bracket into the groove. Part of the bracket should protrude a few centimeters above the slab. The bracket is attached to the wall either with self-tapping screws or anchor dowels if the base is concrete. The slab is placed with the groove up, leveled, pressed tightly to the base of the wall and floor, and tapped with a mallet. At the bottom, from the side where the second slab adjoins, a piece of bracket is again inserted into the groove and screwed to the floor with dowels.

If this plate is installed unevenly, the rest will completely repeat the angle of inclination. Then it will not be possible to level the masonry due to the interlocking joints, so the first slab is given the most attention. After the glue has set, install the next block of the bottom row. Glue is applied to the side ridges and grooves in such a way that the seams between the plates do not exceed 2 mm in thickness. Excess glue is immediately removed with a spatula, and the masonry is checked with a level. Again, attach the bracket at the bottom and secure it to the floor with anchor dowels. Each subsequent block is placed after the glue on the previous one has set.

Step 3. Install the next rows

Since the slabs of the second row must be positioned with offset seams relative to the first, one slab must be sawn in half. At the beginning and end of the row, staples are attached to the sections adjacent to the wall. The glue is made more liquid; it is applied only to the side and bottom grooves of each block. Be sure to check the horizontal and vertical of the masonry. The third row is installed after the glue in the second row has set.

Step 4. Installation of the last row

The top row of masonry should not be closely adjacent to the ceiling. According to the technology, it is necessary to leave 1.5-2 cm between the ceiling and the slabs. To do this, glue staples are inserted into the upper grooves of the last row and screwed to the ceiling with anchor dowels. After installation is completed, the resulting gap should be blown out with foam, and all excess should be cut off.

Installation of a partition with an opening

If you plan to make a door or window opening in the partition, you need to think about ways to attach the slabs above it. For openings with a width of no more than 80 cm, it is allowed to install slabs on door frame or any temporary support, but only on the condition that there is 1 row of blocks above the opening. If the opening width is more than 80 cm or there are several rows on top, be sure to make a strong lintel.

Step 1. Marking and installation of the first row

On the base, mark the location of the partition vertically and horizontally. Connect the markings on opposite walls with two parallel lines along the floor. Determine the location for the opening and mark it on the lines. The installation process is then identical. previous version, only the row turns out to be divided into 2 parts. The box can be installed at the first stage of masonry, or it can be inserted after installation is completed. Openings are also made without a frame if you do not plan to hang the door.

Step 2: Install the jumper

Having reached the top of the opening, cutouts are made in the slabs adjacent to both sides for the lintel. A 35x80 mm steel channel or a wooden beam of the appropriate section is suitable as a jumper. The depth of the cutout is approximately 50 cm, the width is equal to the thickness of the beam. The cutouts are coated with glue and the beam or channel is tightly inserted. When the glue has set, you can begin installing the slabs over the opening.

Step 3: Decorating the corners

To external corners the partitions were not damaged and remained smooth, they need to be strengthened. To do this, use perforated corner profile 30x30 mm. Using a spatula, apply putty to the corner, apply the profile, press it well along its entire length, and cover it with another layer of putty on top. The profile is mounted with an overlap of 3-5 cm, the putty is very carefully and evenly distributed over the surface. To achieve maximum evenness, it is recommended to use an angled spatula.

For internal corners biggest problem there are cracks at the joints. Serpyanka will help to avoid their appearance: putty is applied to the corner, the reinforcing tape is cut to the required length, bent in half lengthwise and applied to the putty. Add another layer of putty and use a spatula for the inner corners to spread it evenly. When choosing self-adhesive tape, you do not need to use putty.

Step 4: Finishing

If you plan to attach wiring and install sockets and switches on the partitions, use an electric drill to drill grooves and recesses in the slabs to the size of the boxes. After installation, all recesses are sealed with putty and sanded. In most cases, leveling the surface with putty for tongue-and-groove slabs is not necessary. After priming, the slabs can be painted or coated decorative plaster, paste over with wallpaper and ceramic tiles. To paint tongue-and-groove slabs, you cannot use paints based on liquid glass and calcareous.

Light objects - paintings, mirrors, lamps - can be attached to ready-made partitions using plastic dowels. Heavy bookshelves or kitchen cabinets secured with lightweight anchor bolts.

Video - Do-it-yourself installation of tongue-and-groove slabs

Tongue-and-groove partitions allow you to obtain a stable, flat surface. They are a good alternative to plasterboard walls, they are easy to install and low in cost. Thanks to the tongue-and-groove connection system, the joining points of the elements become invisible. Due to this, you can skip the putty step, immediately prime and proceed to finishing.

Types of partitions

Partitions made of tongue-and-groove slabs, depending on the material of manufacture, are divided into:

  • Silicate ones are made on the basis of quicklime and water with the addition of quartz sand. The mixture is pressed and kept in an autoclave. They do not burn and have high sound insulation performance. Compared to gypsum species such structures are more durable and resistant to moisture.
  • PGP septum are produced on the basis of gypsum with the addition of plasticizers. They are divided into moisture-resistant (green) and moisture-unresistant. The installation of such partitions can be done in any room, including children's rooms. Gypsum is environmentally friendly, non-flammable, and has good sound insulation.

They are made hollow and monolithic. Hollow material is lightweight, but it will not be possible to hang massive shelves, lamps, etc. on it. Solid ones can withstand heavy loads.

Installation of slabs for partitions is carried out after the construction of all load-bearing structures, but before laying the subfloor and before the start of finishing work.

DIY installation

Installation of partitions from tongue-and-groove slabs is done with your own hands or with the help of professional builders. The material has high thermal insulation, so it can be installed not only inside the room, but also close to cold walls in contact with the street.

The technology for installing tongue-and-groove partitions is quite simple. The main thing is to install the structure level and secure the elements tightly together.

If it is necessary to hide communications without installing grooves, double partition technology is used. The disadvantage is that they take up 2 times more space.

At sub-zero temperatures installation is carried out using frost-resistant adhesives.

Tools

All necessary tools and materials need to be prepared in advance so that during the work process you are not distracted by a trip to the store for missing copies.

It is necessary to assemble such devices for installation interior partitions from tongue-and-groove slabs:

  • felt seal;
  • tongue-and-groove slabs;
  • damper tape, twine;
  • cement, sand, gypsum for preparing the solution;
  • special glue for tongue-and-groove slabs or tile adhesive;
  • primer;
  • building level, tape measure;
  • pencil, ruler;
  • fastening elements: screws, anchors, staples;
  • rubber mallet, spatula, hacksaw;
  • drill, screwdriver, construction mixer.

Consumables should be selected in accordance with the recommendations of the tongue-and-groove slab manufacturer.

Preparatory work

When installing tongue-and-groove partitions in a new house, you need to check the location of the floor and ceiling according to the horizontal level. Protruding parts of the surface are cleaned by grinding. Cracks and depressions are filled with cement-sand mortar.

The floor and ceiling must be prepared so that the tongue-and-groove slabs fit snugly against them. Before installing partitions, all surfaces that will come into contact with them are treated with a primer.

When installing partitions during current repairs Markings are made on the floor, ceiling, and walls. Mark the location of the partition with a line. Remove everything from surfaces Decoration Materials several millimeters wider than the markings indicate. Firmly held ceramic tiles do not need to be dismantled.

At a height of 30 cm from the floor, a string is pulled, which will indicate the level of the partition. Along the line of contact of the partition with the surfaces, a damper seal is glued: felt impregnated with bitumen or a cork backing. The width must correspond to the thickness of the slab.

Construction of the first row

The location of the entire structure will depend on the correct installation of the first row. Here is information on how to make a partition from tongue-and-groove blocks.

Step-by-step installation instructions:

  1. For tongue-and-groove slabs that will be located in the first row, the lower ridges are cut off using a hacksaw.
  2. Glue is applied to the vertical and horizontal parts of the sealing material.
  3. Place a perforated bracket on that part of the slab groove that will be adjacent to the wall, so that the fasteners protrude a few centimeters.
  4. Fasten the bracket to the wall using dowels or self-tapping screws.
  5. Place the slab with the groove up, press it tightly against the wall and floor, check that it is level, and tap it with a rubber mallet.
  6. From the installation side of the next slab, a bracket is inserted into the groove and secured to the floor using dowels.
  7. After the adhesive has set, install the next slab and secure it with a bracket to the floor.
  8. Each subsequent block is mounted after the glue has set on the previous one.

The adhesive composition is applied to the side joints so that the distance between the plates does not exceed 2 mm. Excess glue that appears is immediately wiped off; after hardening, removing drips will be problematic.

When erecting walls from PGP, maximum attention is paid to the installation of the first row. The quality of its installation will determine the reliability and appearance the entire structure.

Construction of the remaining rows

The second and subsequent rows are mounted with offset seams. The first slab of the second row is sawn in half. The row starts from half a block. Staples are attached to the sections of tongue-and-groove blocks adjacent to the wall.

The adhesive composition is diluted so that it is more liquid than what was used for the first row. Apply the adhesive composition to the bottom and side joints of each slab. Using this technology, the entire wall is assembled.

Be sure to check the horizontal and vertical levels after installing each block.

Installing the last row

According to the technology, there should be a compensation gap of 2 mm between the ceiling and the blocks of the top row.

Staples are attached to the upper grooves of the last row with glue. Install the block and screw the bracket to the ceiling using dowels. If the slab is larger than the remaining distance, it is cut to the required size.

After the glue has hardened, the seam between the ceiling and the wall is blown out polyurethane foam. When it hardens, cut off the excess with a knife.

Technology for installing partitions with doorways

When the partition design includes a doorway, you need to think about how to strengthen the rows that will be located above the opening.

If there is only one row of slabs above an opening up to 800 mm wide, then it is permissible to mount them on top of a door frame or temporary support.

In the case where the opening is wider than 800 mm or several rows will be laid above it, you will need to install a reliable lintel made of thick wooden beam section 50 x 50 mm or metal channel 35.

Partitions made of PGP with the arrangement of a doorway are mounted using a technology similar to the construction of a solid wall. The difference is that when markings are made, the location of the opening is noted, the wall turns out to be divided.

Lintels above the doorway:

  1. When the row reaches the upper level of the opening, cutouts about 50 mm deep are made in the blocks on both sides. The width of the cutout is equal to the thickness of the timber or channel.
  2. Lubricate the blocks with glue and insert the jumper.
  3. After the adhesive composition has hardened, the upper rows of blocks are installed.

If you plan to install in the partition interior door, the box under it can be mounted both at the stage of wall construction and subsequently.

Strengthening corners

To ensure that the external corners are 90 degrees and do not collapse under mechanical stress, they are strengthened using perforated corner 3 x 3 cm.

Instructions for attaching corners:

  1. Using a spatula, apply putty to the surface of the corner and press the steel corner to it. Press it along its entire length.
  2. If the length is not enough, take another strip and overlap it by 3 cm.
  3. Apply a layer of putty on top using an angle spatula.

By internal corners lay a serpyanka tape. If it does not have a self-adhesive base, it is attached using the same technology as a perforated corner.

From serpyanka to self-adhesive base remove protective layer and glue it along the entire length of the corner.

Electrical wiring in partitions

After the partition is installed, it may be necessary to install sockets or switches. For device hidden wiring mark the location of elements electrical system, make a groove for the wires and holes for the boxes.

Technological cavities inside hollow partitions made of gypsum tongue-and-groove slabs can be used for laying electrical wiring. To make it more convenient to lay wires in horizontal channels, blind holes are made on the sides.

They stretch wires, connect sockets and switches. Seal the holes with putty.

The distance between the grooves should not be less than 10 cm.

Finishing walls from tongue-and-groove slabs

Like any material, walls made of tongue-and-groove slabs need finishing. Materials for its construction are chosen depending on functional purpose premises.

It is appropriate to lay ceramic tiles in the kitchen and bathroom. For living room and bedrooms will do finishing with decorative plaster, wallpaper, painting with water-based paints.

Painting

Before painting, the surface is puttied with fine-grained compounds, allowing you to get a perfect smooth surface. After drying, rub the surface with a fine sanding mesh. Apply two layers of primer.

Prepare the paint desired shade obtained by adding colors.

Start painting. Apply the paint with a roller, making sure that the layer is even. Several coats of paint may be required.

Wallpapering

Cover the surface with a primer and apply thin layer plaster or putty.

Wallpapering is done according to the usual scheme. Dilute the glue, cut off a strip of wallpaper to the required length. Apply glue to the wallpaper and wall. Apply the strip and smooth it with a rubber roller, expelling air bubbles.

When decorating with wallpaper, there should be no drafts in the room.

Laying tiles

Ceramic tile finishing does not require preliminary preparation surfaces.

Instructions for laying tiles:

  • the surface of the partition is cleared of construction debris;
  • the protrusions are cleaned with sandpaper;
  • depressions, cracks are filled cement mortar;
  • for better adhesion of materials, the wall is covered with two layers of primer;
  • laying tiles.

Since the gypsum surface absorbs water, the surface after installation of the tiles is not touched for 3-5 days.

You can see how to install tongue-and-groove blocks in the video:

A partition made of tongue-and-groove slabs is very easy to assemble and represents reliable design. Finishing Such a surface can be made with any materials you like.

Partitions made from PGP are used for redevelopment of premises or delimitation of apartments in new buildings. They differ flat surface, ease of installation and budget cost. The blocks are connected using a tongue-and-groove system, the seams are on finished design minimal. This makes it possible not to putty, but to immediately coat the wall with a primer and decorate it.

Tongue-and-groove slabs for partitions are rectangular elements with longitudinal grooves and protrusions (ridges) at the joints, necessary for a strong and seamless bond. Their standard sizes- 667x500x80 mm, thickness can be 100 mm.

There are tongue-and-groove slabs for partitions large sizes, height from floor to ceiling.

Their installation occurs very quickly, but you cannot cope with it yourself - due to heavy weight A whole team is involved in the installation of building elements.


Types of tongue-and-groove blocks for interior partitions, depending on the material of manufacture:

View Preparation method Positive traits
Gypsum boards Made from gypsum with plasticizing additives. Gypsum blocks for partitions are divided into moisture-resistant (green) and those whose moisture permeability is high. Allowed for installation in children's rooms. Another advantage of gypsum blocks is their ease of processing. Gypsum blocks can be sawn at any angle - gypsum elements can be used to create structures of various shapes and configurations.
Silicate blocks From quicklime and water with the addition of quartz sand using an autoclave. They have significant noise insulation qualities. Compared to gypsum, they are resistant to moisture and have greater strength and durability.

PGP partitions can be solid or hollow. The latter weigh less (22 kg compared to 28 for monolithic ones), but cannot withstand hanging massive household items.

Advantages of GGP partitions

The general advantages of partitions made of gypsum or silicone tongue-and-groove plates are:


The use of hollow slabs reduces the load on the supporting base.


The main advantage of such building elements: installation of tongue-and-groove partitions is not difficult. The finished structure does not require any special finishing work. There is no need to plaster the wall, just cover it with a primer and decorate it.


Installation of partitions from PGP

The installation of partition elements made of gypsum or silicate in the apartment begins after the construction of load-bearing parts, but before laying the subfloor and starting painting and plastering work.

Installation of a partition made of standard-sized tongue-and-groove slabs takes only two to three days. This is due to the convenient tongue-and-groove system and the absence of the need for additional reinforcement.

When docking, any deviations along the planes are excluded, which allows you to assemble in a short time flat wall without even a millimeter error.

If you need to hide communications, special grooves are made in solid blocks. In hollow ones, wires and pipes can be laid in the internal cavity. If the construction of partitions from PGP does not involve gating, use the method double walls. But they “eat up” twice as much space.


Materials and tools

To build a partition from tongue-and-groove slabs you will need the following set of tools:

  • roulette;
  • electric drill;
  • mallet;
  • construction level;
  • putty knife;
  • hand saw;
  • ruler, pencil;
  • screwdriver;
  • mixer for mixing glue.


The materials you will need are the blocks themselves, a cork or felt seal, edge tape, rope, glue, and primer. Fastening elements are also needed: screws, dowel-nails, fixing brackets - straight hangers or corners.


Preparatory work

The construction of a partition created from tongue-and-groove blocks requires certain preparation. First of all, you need to check the compliance of the floor and ceiling horizontal levels, and make sure that the tongue-and-groove slabs are closely adjacent to them: smooth out prominent irregularities, fill cracked areas and depressions with a solution of cement and sand.


The blocks are brought into the room no later than 24 hours before installation so that the material “adapts”, that is, has the necessary humidity and temperature.

To build the wall, gypsum-based acrylic adhesive is used.

But it is very expensive, so many people replace it with regular tile adhesive or a solution of cement and sand in a ratio of 1:3 with the addition of polyvinyl acetate glue. If everything is thoroughly mixed, the result is a fairly plastic and finely dispersed mixture that can be easily applied with a spatula. It is easier to make masonry with mortar, since its setting time is longer than that of gypsum glue.


Before constructing interior partitions, all surface areas in contact with them are primed and marked according to the previously created drawing.


Laying tongue-and-groove blocks

It is not difficult to assemble a partition from tongue-and-groove slabs with your own hands. The main thing is not to violate the technology when constructing a bulkhead from PGP.


Installation guide for partitions made of tongue-and-groove slabs - step-by-step instructions:


If the structure of a false wall requires an opening for a door, it is necessary to fix the blocks located on top. When installing one row of blocks over an opening up to 0.8 m wide, it is permissible to install them on a door frame or a non-permanent wooden lintel.

If the width is more than 0.8 m or it is necessary to lay several rows, you will need to install a lintel for tongue-and-groove slabs made of wooden blocks or a metal channel.

It is mounted with glue in specially made cuts approximately 5 cm deep in corner blocks. After the solution has dried, the upper rows of slabs are installed.


After finishing the work, the tongue-and-groove partitions need to be primed. Especially if tongue-and-groove gypsum boards were used. The primer ensures adhesion of the decorative layer and will avoid the appearance of surface defects.


Any type of wallpaper and painting are suitable for finishing. It is better to finish the kitchen and bathroom tiles or plastic panels. For the living room, children's room, and bedroom, wallpaper or decorative plaster is often chosen.


You can install tongue-and-groove partitions yourself, because this does not require special skills or knowledge. The material is very easy to use, does not require careful surface preparation, installation lasts a matter of hours. Gypsum boards, from which partitions are built, have a number of advantages, and therefore are increasingly used in private construction.

Properties and characteristics

Tongue and tongue slabs are often used: what is it? This material It is a monolithic rectangular gypsum slab mixed with various additives. Features of the slabs are longitudinal grooves and protrusions (ridges) at the joints, providing additional strength to the finished structure. The elements are connected using glue.

Properties of tongue-and-groove slabs:

  • the material is non-toxic;
  • high resistance to temperature fluctuations;
  • have no odor;
  • resistant to rot and insect activity;
  • have high sound absorption;
  • vapor permeable;
  • easy to process with carpentry tools.

For rooms where humidity is high, moisture-resistant PGPs are produced, which differ from ordinary ones in a light green color. During their production, hydrophobic additives are added to natural gypsum, which are absolutely harmless to humans.


Main technical characteristics:

  • standard size - 667x500x80 mm;
  • weight hollow slab— 22 kg, full-bodied — 28 kg;
  • density - 1030 kg/m³;
  • compressive strength - 5.0 MPa;
  • bending strength - 2.4 MPa;
  • high fire resistance.

Advantages of tongue-and-groove partitions

Partitions from PGP are assembled according to the principle of a designer, so one person can install about 30 m² in a day. Even if you have no experience, understanding the process will not be difficult; just read the instructions and look at the photos. The main thing is to correctly mark the partition. The advantages of the material are:

  • when installing partitions made of tongue-and-groove slabs, there are no wet processes; wallpapering can be carried out immediately after installation work;
  • with a small thickness, the partitions are distinguished by good strength and thermal insulation;
  • due to the absence of voids in the connecting seams and gaps at the junctions with the main wall, sound insulation in the room is improved;
  • the flexibility of PGP joints eliminates the appearance of cracks and deformations;
  • The material can not only be wallpapered, but also painted, tiled, and covered with decorative plaster.

Partition installation technology

For 1 m² of a single partition, 5.5 slabs and 1.5 kg are required special glue. Before starting work, the material must be brought into the room and left for at least 4 hours. The temperature inside the room should not be lower than +5° C.

Additionally you will need:

  • cork gasket;
  • building level;
  • marker and tape measure;
  • container for glue and water;
  • drill with attachment;
  • trowel;
  • rubber hammer;
  • staples made of galvanized steel;
  • self-tapping screws and anchor dowels.

Work begins by cleaning the surface at the junction of the structure. Wallpaper and peeling finishes must be removed, large unevenness must be smoothed out with cement mortar or putty. If the wall is smooth, the paint (plaster) adheres firmly, it is enough to remove dirt and dust. The floor is prepared in the same way. Next, markings are made on the floor for the partition, and the locations of the openings are marked. Using a level, the marking line is transferred to the ceiling and walls.

Prepare the glue: pour water into a container, add the dry solution, mix with a nozzle and let it sit for 3 minutes. Mixing proportions are indicated on the packaging. U different manufacturers They may differ, so you should read the instructions carefully. Apply a strip of glue according to the markings and apply a cork lining. As soon as the glue sets, you can install the first row of slabs.


A layer of glue is applied to the lining, after which the ridge on the long side of the first slab is cut off and installed with this side down. Level the PGP, coat the side cut with glue and install the second slab. Each fragment must be checked by level, correcting rubber mallet. For the second row, the first slab is sawn in half to offset the vertical joints. For connecting partitions made of tongue-and-groove slabs with load-bearing wall At the junction points, staples are installed. One end of the bracket is fastened with self-tapping screws to the slab, placing it in a horizontal groove, the second is fixed with anchor dowels to the wall. The step of such fastenings is through 2 plates.

When making openings there are also some nuances. If there is only one row of slabs above the opening, and the width is no more than 80 cm, it is enough to place a temporary support until the glue dries. For larger widths, be sure to install a jumper: wooden beam or metal channel the corresponding section.

The upper edge of the last row of PGP is sawn at an angle to avoid the formation of voids when filling the seams.


The distance from the edge of the slab to the ceiling should be 1-3 cm. After installing the last element, the gap between the partition and the ceiling is sealed with gypsum mixture or filled with mounting adhesive. At this point, the installation of partitions made of tongue-and-groove slabs is considered complete. The fastening of shelves, cabinets, mirrors and other objects to such walls must be carried out taking into account the load exerted. Up to 30 kg/cm, fastening is carried out using anchor plastic dowels; at higher values, galvanized bolts are used, passing through the entire thickness of the slab.

Conclusion on the topic

When remodeling an apartment, partitions made from PGP are the most profitable solution. In addition to zoning the space, they create additional sound and heat insulation, which allows you to save on materials. But the main advantage is still considered ease of installation, because the services of specialists are very expensive. If you follow the instructions exactly, carry out each stage efficiently and carefully, the partition will turn out no worse than that of professional builders.
