Strengthening of tongue-and-groove partitions. Technology for the construction of partitions from tongue-and-groove plates. Doorways in the partitions of their tongue-and-groove plates

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 the additional load on the supporting structures of the building. Thus, the choice is narrowed down to masonry materials such as tongue-and-groove slabs and blocks.

The construction of partitions inside already finished housing has certain specifics. It will be necessary not only to accurately mark the place for the construction of an additional wall, but also to prepare a base for it, create a vibration-damping damper layer at the junction, provide for fastening the blocks to the walls, and competently organize doorways or arches. Perfect geometry and impeccable quality of masonry will be provided by the masters of the company “Remont Prestige”. They have to solve the task of erecting partitions from tongue-and-groove slabs and blocks at almost every facility where redevelopment of premises is provided, and they have mastered the technology to perfection. In favor of concluding an agreement with our company, to short deadlines and excellent quality, you can add very affordable prices for this species works.

Price list for works on the installation of partitions from tongue-and-groove plates

Unlike the “flying crews”, the “Remont-Prestige” company does not disappear anywhere after the commissioning of the facility. We have been on the market for almost 10 years, and our long-term guarantee allows customers not to worry about problems that may arise during the operation of partitions, which, however, is unlikely.

Blocks or tongue-and-groove slabs?

First of all, it is worth deciding what material to build partitions from - from gypsum blocks or from tongue-and-groove plates. From the point of view of composition, they are identical, but they have a different shape, due to which their installation technologies, performance characteristics and cost of partitions differ.

The gypsum block is a regular parallelepiped with smooth edges and right angles. The ideal geometry of products is achieved thanks to a special production technology that 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 plates used for the construction of interior partitions are usually 66.7 x 50 cm. Thanks 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 from blocks will be somewhat cheaper than from tongue-and-groove slabs, 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 set the blocks along the planes, fix them without distortions and overspending of the adhesive mixture. Such a wall, moreover, is 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 (hollow blocks can be used as an alternative). A wall made of tongue-and-groove slabs will cost more, but its construction does not require an ideal eye and high professional skills.

Preparing to build a partition

First of all, you need to use laser level mark the walls and floor, 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 a platform for 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, their deviation from the horizontal plane is possible. Therefore, the surface is checked by level. Drops of more than 3 mm are leveled cement mortar. A thin platform can be filled with a self-leveling mixture by setting up a kind of formwork and using a roller with needles to evenly distribute the composition. Significant differences are eliminated using a semi-dry screed. It is prepared by mixing cement 500 and fine sifted sand in a ratio of 1: 3, adding water until a wet mass is obtained. The mass is laid out on a prepared base and checked by level. After drying (1-2 days), the finished site is treated with a primer, as well as a floor slab.

To compensate for thermal expansions 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 (plates). This damper tape can be installed on the same adhesive on which the boards will be mounted.

Partition masonry

The laying of slabs and blocks is carried out staggered, 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 plates are placed with the groove up, before installing the first row, the comb is sawn off. Glue or mortar with a spatula is spread on the tape (for the first row and blocks adjacent to the wall), then on the block itself. Landing of structural elements is achieved by tapping with a hammer through a bar or a special hammer with a rubber pad. The excess adhesive squeezed out 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, wood screws are used, for walls and floors - dowel screws or anchors. The gap between the top row and the ceiling is foamed and leveled.

PGP partitions are used for redevelopment of premises or for delimiting apartments in new buildings. They are distinguished by a smooth surface, ease of installation and budget cost. The blocks are connected using a tongue-and-groove system, the seams on the finished structure are minimal. This makes it possible not to putty, but immediately cover 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, the thickness can be 100 mm.

There are tongue-and-groove-type slabs for partitions of large sizes, floor-to-ceiling high.

Their installation takes place very quickly, but you cannot cope with it on your own - due to the large weight of the building elements, a whole team is involved in the installation.

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

View	Preparation method	Positive traits
Gypsum boards	From gypsum with plasticizing additives. Gypsum blocks for partitions are divided into moisture resistant (green) and those whose moisture transmission capacity is high.	Approved for installation in children's rooms. Another plus of gypsum blocks is ease of processing. Gypsum blocks are 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 soundproofing properties. Resistant, compared with gypsum, to the action of moisture, have greater strength and durability.

PGP-partitions can be corpulent and hollow. The latter weigh less (22 kg compared to 28 for monolithic ones), but do not withstand the suspension of massive household items.

Advantages of GWP partitions

The general advantages of a partition 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: the installation of tongue-and-groove partitions is not difficult. The finished design does not require special finishing works. It is not necessary to plaster the wall, it is enough to cover with a primer and decorate.

Installation of partitions from PGP

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

Installation of a partition from standard-sized tongue-and-groove plates 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 a smooth wall in a short time without even a millimeter error.

If you need to hide communications, special strobes are made in full-bodied blocks. In hollow wires and pipes can be laid in the inner cavity. If the construction of partitions from PGP does not involve gating, the double wall method is used. 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;
glue mixer.

From the materials you will need the blocks themselves, a sealant made of cork or felt, edging tape, rope, glue, primer. Fasteners 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 some preparation. First of all, you need to check the correspondence of the floor and ceiling horizontal levels, and make sure that the tongue-and-groove slabs closely adjoin them: grind outstanding irregularities, fill cracked areas and recesses 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, it has the necessary humidity and temperature.

Used to build a wall acrylic adhesive based on gypsum.

But it is very expensive, so many people replace it with ordinary tile adhesive or a 1: 3 cement-sand mortar with the addition of polyvinyl acetate adhesive. If everything is thoroughly mixed, a rather plastic and finely dispersed mixture comes out, easily applied with a spatula. Laying with a mortar is easier, since its setting time is longer than that of gypsum glue.

Before the construction of interior partitions, all areas of surfaces in contact with them are primed and marked according to a previously created drawing.

Laying tongue-and-groove blocks

It is not difficult to assemble a partition from tongue-and-groove plates with your own hands. The main thing is not to violate the technology during the construction of bulkheads from GWP.

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

If an opening for a door is required in the design of a false wall, it is necessary to fix the blocks located on top. When mounting one row of blocks over an opening up to 0.8 m wide, we can mount 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, it will be necessary to install a jumper for tongue-and-groove plates made of wooden blocks or a metal channel.

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

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

For decoration, any type of wallpaper and coloring are suitable. Kitchen and bathroom needs to be redone tiles or plastic panels. For the living room, nursery, bedroom, wallpaper or decorative plaster is more often chosen.

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 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 tongue-and-groove partition their 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. There are no other criteria for flexible installation of 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 slab is carried out in a room with normal humidity, a standard PGP slab is purchased. 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

Interior partitions made of 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 with 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 soundproofing 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 100 mm, 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 the building level to control the installation.

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).

Manufacturers building materials constantly use innovative technologies to improve quality and speed up repairs. In addition, it is important to minimize costs and simplify the construction process. For zoning space with the least difficulty, you can use partitions made of tongue-and-groove slabs. They are a good alternative drywall walls and allow you to get a smooth and stable structure.

Types of tongue-and-groove plates and their advantages

The tongue-and-groove plate differs from other similar materials in the presence of groove-comb joints at the ends. This feature makes it possible to connect adjacent elements, ensuring the smoothness of the surface and the strength of the partition.

There are two types of tongue-and-groove slabs: gypsum and silicate. Each type has its own advantages and disadvantages, which should be taken into account when building walls.

For the manufacture of gypsum blocks, building gypsum and special plasticizers are used. This material compares favorably with others and makes it possible to produce high-quality partitions from tongue-and-groove plates. They can be both standard and moisture resistant (green) and suitable for use in rooms with any level of humidity.

The main advantages of gypsum boards are: environmental friendliness, high fire resistance, good sound insulation. In addition, hollow blocks can be used, which will reduce the weight of the structure. Their only drawback is the difficulty with hanging shelves and other additional elements. But solid blocks can withstand almost any load, which distinguishes them even from plasterboard partitions.

The main advantage of any partition made of tongue-and-groove plates is simplicity finishing. It is not necessary to plaster such a surface, it is enough just to prime it. After that, it can be painted or wallpapered.

Water is used to make silicate boards. quicklime and quartz sand. The resulting material has high strength (compared to gypsum) and moisture resistance. At the same time, they are “not afraid” of fire and absorb sound well.

Partition wall installation instructions

The process of installing walls can be considered using gypsum blocks as an example. This material is one of the most sought after in any repair and is perfect for the construction of interior partitions. Installation should be carried out after finishing work on leveling the floor surface. It is best to use materials from well-known manufacturers. For example, Knauf. This will avoid unpleasant surprises and problems.

To install partitions from tongue-and-groove plates, you need to purchase a number of components and the necessary tools:

gypsum boards;
mounting adhesive;
putty for gaskets;
gaskets (suitable from treated felt or cork);
drill;
mixer;
hacksaw;
level;
rule;
rubber mallet;
roulette;
marker or pencil;
ribbon or twine;
putty knife;
wedges.

After the issues of purchasing materials are resolved, you can proceed to the implementation of the main points of the installation. The installation diagram will look like this:

markup;
cleaning of dirt from all surfaces adjacent to the future partition;
gluing the gasket to the installation sites of the plates (Fügenfüller putty is used);
installation of the first row of tongue-and-groove plates;
laying the second row;
installation of the last row (the edge of the plates must be beveled);
sealing seams;
finishing.

At first glance, everything is simple: a partition made of tongue-and-groove plates is assembled as a constructor, and there are no problems. But there are some nuances that need to be taken into account.

Firstly, at least a day before installation, it is necessary to bring the blocks into the room. This is necessary in order for the material to “get used to”, that is, to accept the desired humidity and temperature. Secondly, laying is done with the groove up. The grooves are subsequently filled with putty. Before laying the second row, you need to cut the first slab into two parts. This is necessary to arrange the vertical joints in a checkerboard pattern and to impart mechanical strength to the structure. Important: the width of the seams horizontally and vertically must be equal!

After the installation of the partition is completed, the surface of the tongue-and-groove plates must be primed. This will ensure the adhesion of the decorative layer and avoid the occurrence of surface defects. For decor, any type of wallpaper and coloring are suitable. The main thing is to choose the ornament or shade you like and carefully apply it to the partition.

Here are a few tips to help you complete the installation of walls in the most efficient way:

“In many sources there is information that a slab partition can be installed in one day. It is not right. It is best to let the first layer “settle” for a day, and then continue to work.” Zoya makes repairs with her own hands.
“Although they say that work with tongue-and-groove blocks is carried out practically without dirt and dust, this is not entirely true. The sawing process is quite dusty, so you should be prepared for constant cleaning.” Oleg, a novice repairman.
“The material is quite new for our market, but already popular. I liked it not only for the smoothness of the surface, but also for the ease of installation. I only hung shelves and a TV on the finished wall, but I didn’t dare cabinets, ”Dmitry is repairing the dacha.

At first glance, partitions made of tongue-and-groove blocks are perfect option erecting walls and zoning space. However, this material also has its drawbacks. Information on how to solve problems that arise during installation and operation would not hurt. Share with us your experience!

Partitions made of tongue-and-groove slabs (hereinafter referred to as GWP) are a prefabricated large-block structure. Blocks are made by molding. They are distinguished by increased accuracy - the deviation of the working surfaces is not more than 1.5 mm from the specified one. Depending on the raw materials used, they are divided into two types:

silicate. Produced by silicification of quartz sand and lime in an autoclave under the influence of high temperatures. This technology makes it possible to obtain a durable, moisture-resistant, non-combustible material.
Gypsum. The main raw material is gypsum. For achievement desired characteristics plasticizers and other chemical additives are introduced into it. This makes it possible to obtain the necessary strength and moisture resistance. Depending on this product are divided into types. The environmental safety of raw materials makes it possible to use it without restrictions even in children's rooms.

The sizes of tongue-and-groove blocks for partitions from different manufacturers may vary. We list the most common options:

667x500;
250x500;
300x900;
599x199.

Partition plates of all standard sizes are produced with a thickness of 70, 80 and 100 mm. Depending on the design, they are divided into two types:

Full bodied. They are solid monolithic elements. They are used if you need to provide high strength, for example, hang heavy shelves or lockers.
Hollow. They have round perforations. This makes them lighter and therefore easier to install. Due to the voids, the products have increased sound insulation. They can also be used as conduits for electrical wiring.

Depending on the purpose of the premises, inner wall can be made single or double. If you place a mineral wool insulation between the gypsum panels, you can achieve one hundred percent sound insulation between adjacent apartments.

Pros and cons of using tongue-and-groove blocks for partitions

Advantages:

Availability. The use of the material is economically justified. Prefabricated gypsum structures are lighter than ceramic bricks, stronger than drywall and gas silicate foam. At the same time, their cost is lower by 10-30%.
Safety. Raw materials for the production of GWP do not contain impurities harmful to health. The products themselves are highly fire resistant.
Soundproofing. Subject to the installation technology, the wall prevents the penetration of loud sounds into adjacent rooms.
Ease of installation. Thanks to the connection individual elements according to the tongue-and-groove principle, even a person without experience in carrying out such work can cope with the construction of the PGP. The main thing is to correctly mark up and constantly control the straightness of the rule.
Ease. The material is almost twice as light as brick, which reduces the load on interfloor overlap. At the same time, you get thinner interior partitions, which gives additional usable area.

Flaws:

Hygroscopicity. Standard tongue-and-groove slabs absorb moisture well, and during the drying process they can be deformed. Therefore, it is important to mount them after the completion of all wet processes in the room.
Fragility. At high loads, the material bursts at the point of greatest stress. Therefore, before the device of the wall along wooden floor, it needs to be well reinforced. In new buildings, which can shrink, it is imperative to use damping tapes.
Foundation requirements. The large-block structure does not allow the adjoining surfaces to be leveled during the construction of walls, as can be done, for example, with a brick. This means that you first have to carefully align all the planes.

Technology of installation of partitions from tongue-and-groove plates

The construction of the GWP is started after the completion of plastering work, laying of electrical and plumbing communications, but before the installation of subfloors. Humidity should not exceed 60%, and the air temperature should be above 5 degrees.

Foundation preparation

All adjoining surfaces must be flat, strictly horizontal or vertical. If the planes do not correspond to the level, we level them with concrete or cement-sand mortar. The hardened base is dedusted and primed.

We apply markings on the floor in accordance with the project and mark the location doorways. With the help of a level or a laser line builder, we transfer the lines to the walls and ceiling.

You can quickly and perfectly evenly draw marking lines with a construction chopping cord. It's better to do it together.

To increase sound insulation, we glue a cork elastic gasket with a mounting solution to all surfaces adjacent to the GWP. We press it with a building level, controlling the correspondence of the vertical and horizontal.

For novice craftsmen, the contour of the cork gasket helps to achieve the perfect geometry of the walls. It serves as a guide when checking planes with a rule.

Partition wall fastening

Regular fasteners for PGP are brackets C3 (with a thickness of 1 cm) and C2 (with a thickness of 0.8 cm). They are screwed with screws to the walls, ceiling and wooden floor at the junction. On concrete floor the necessary strength creates an adhesive solution.

But more often for fastening they use mounting equal-shelf corners 100x100 mm or drywall hangers.

With a ceiling height of 2800 mm, it is enough to fix the vertical in three places. Horizontally, fasteners are installed every 600 - 1000 mm.

Gypsum panels remain stable when erecting straight structures up to 3600 mm high and 6000 mm long. The distance is measured between the corners of the intersection.

Corner plates must be fastened to each other with perforated tape or a suspension for plasterboard.

The construction of the first row of tongue-and-groove blocks

After delivery of the material to the object, it must be laid down for a day. During this time, the temperature and humidity levels out.

Gypsum panels can be laid with the groove up or down. In the first variant, the mortar mixture is more evenly distributed over the plane of contact between the elements. Therefore, before the device of the first row with a hacksaw with large tooth cut off the comb from the bottom side. Installation is carried out in the following sequence:

Knead a small portion of the adhesive solution. Particular attention should be paid to the time of its viability. Usually it is 30-60 minutes.
We apply glue according to the markings on the floor and wall.
We install the first tongue-and-groove block. We apply the level from above and, tapping with a rubber mallet, align the horizontal. Each time, with a small level or a long marking rule, we control the vertical.
Immediately remove the excess mortar mixture. When hardened, it will spoil the finish coating.
If necessary, we fix the plate to the enclosing structures.

We repeat the steps for the remaining elements of the first row. We pay special attention to the conformity of dimensions, straightness and verticality. For control, we use the level, roulette and the rule.

The construction of subsequent rows

General principles installation remain the same, but there are some peculiarities. Do not allow the vertical seams of adjacent rows to coincide. It is necessary to perform them with a run of at least 1 cm. To do this, cut the block in half. We install one part of it on the whole panel, which started the first row. The second one is used as a supplement.

It is important to observe the dressing in the corners and intersections of the walls. If the block has a groove and a ridge along its entire length, we cut them at the corner joints. Otherwise, the comb will not go into the groove.

Due to the low viability of the adhesive solution, we first cut the parts and adjust their size to dry. Only after that we fill the groove with glue, and install the element. Be sure to remove the squeezed out excess mortar mixture.

Formation of doorways

When arranging an opening up to 900 mm wide, you can do without additional load-bearing structures. At the same time, it is important to arrange it so that there are no freely hanging plates above the door. Therefore, for such places, we first draw a laying scheme on paper. We start with a row above the doorway. We place the vertical seam in the middle of the span. Only then do we paint the rest of the elements, adhering to the rule of spacing the seams.

At the stage of erecting the wall, we fasten a temporary jumper made of wood or a drywall profile (supports are allowed). After the adhesive mixture has hardened, remove the temporary mounting parts.

Above openings wider than 900 mm, we must install a jumper: a wooden block, a metal corner or a channel. The support should be in the range of 100-150 mm. The top of the door does not have to be aligned with the horizontal mounting joint. It is enough to cut the groove for the jumper at the right level.

It is important to think in advance about the finishing of embedded elements. Metal parts are covered with paint in three layers. We impregnate the wooden ones with an antiseptic, and for better adhesion we sheathe the front parts with strips of drywall.

The construction of the last row of tongue-and-groove blocks

It is inconvenient to finish laying with narrow trimmings. Therefore, for ease of installation, it is allowed to install the plates of the upper row vertically. The tongue-and-groove system does not allow joining the elements right up to the ceiling. A clearance is required for their installation. To facilitate the sealing of the seam, we cut the upper plane diagonally. On the side closest to the installer, a gap of 2-3 millimeters is sufficient. The cutting line of the far part should be at a distance of 2-5 cm from the overlap.

If you are planning to install stretch ceiling, fill the gap mounting foam. When it is important to make a smooth abutment, we fill the hole gypsum plaster. We do this in several stages, observing the layer thickness recommended by the manufacturer.

It is important to fix the GWP to the ceiling with mounting brackets or corners. Otherwise, the top edge may become loose.

Electrical installation

If necessary, we lay wiring in the tongue-and-groove partitions, install sockets and switches. In hollow blocks we use internal channels. If you know the places for laying communications in advance, you can pre-drill holes in the ridge to desired diameter. This will make wiring easier.

In full-bodied panels, we cut the strobes with a manual or mechanical strobe cutter. Holes for socket boxes are drilled with crowns on wood.

It is not allowed to use impact tools: hammer drill or impact drill.

Prepared channels are dedusted and primed. After installing the cables, we seal the strobes with a gypsum adhesive solution.

For clarity, and to simplify the installation of partitions from tongue-and-groove plates with our own hands, we provide a video instruction.
