Reinforcement of tongue-and-groove partitions. Technology of 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 additional stress on the building's supporting structures. Thus, the choice is narrowed down to masonry materials such as tongue-and-groove plates 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 an agreement with our company, to the tight deadlines and excellent quality, you can add very affordable prices for given view works.

Price list for works on the construction 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, and our long-term warranty allows customers not to worry 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, 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 the area under blocks or slabs, the base is treated with a primer on 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 more than 3 mm equalize 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. It is prepared 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 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 (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 comb 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.

Partitions from GWP are used for redevelopment of premises or delineation of apartments in new buildings. They are distinguished by their flat 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 to immediately cover the wall with a primer and decorate it.

Tongue plates 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 slabs of tongue-and-groove type for large partitions, from floor to ceiling.

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 engaged in installation.

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

View	Preparation method	Positive traits
Gypsum boards	Made of gypsum with plasticizing additives. Gypsum blocks for partitions are divided into moisture resistant (green) and those whose moisture permeability 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 - you can create structures of various shapes and configurations from gypsum elements.
Silicate blocks	From quicklime and water with the addition of quartz sand using an autoclave.	They have significant soundproofing qualities. They are resistant, in comparison with gypsum, to the action of moisture, have greater strength and durability.

GWP-partitions can be full-bodied and hollow. The latter weigh less (22 kg compared to 28 for monolithic ones), but do not withstand hanging massive household items.

Benefits of PGP partitions

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

The use of hollow core slabs reduces the load on the substructure.

The main advantage of such building elements: 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 PPG

The device of partition elements made of gypsum or silicate in the apartment begins after the construction of the supporting parts, but before laying the sub-floor and starting the painting and plastering work.

Installation of a partition made of 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 joining, any deviations along the planes are excluded, which allows you to assemble a flat wall in a short time without even a millimeter error.

If you need to hide communications, special strobes are made in full-bodied blocks. The hollow wires and pipes can be laid in the inner cavity. If the construction of partitions from GWP does not imply slitting, use the double wall method. But they "eat up" twice as much space.

Materials and tools

To build a partition from tongue-and-groove plates, 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 themselves will require the blocks themselves, a cork or felt seal, edging tape, rope, glue, primer. We also need fasteners: screws, dowel-nails, fixing brackets - straight suspensions or corners.

Preparatory work

The erection of a partition created from tongue-and-groove blocks requires some 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 adjoin them closely: 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, has the required humidity and temperature.

For the construction of the wall, use acrylic adhesive based on gypsum.

But it is very expensive, so many people replace it with ordinary tile glue or a mortar of cement and sand in a 1: 3 ratio with the addition of polyvinyl acetate glue. If everything is mixed thoroughly, a rather plastic and finely dispersed mixture comes out, easily applied with a spatula. It is easier to lay masonry with mortar, 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 a bulkhead from GWP.

Installation instructions for tongue-and-groove partitions - step-by-step instructions:

If the structure of the false wall requires an opening for the door, it is necessary to fix the blocks located on top. When installing one row of blocks above an opening up to 0.8 m wide, it is permissible to 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 lintel for tongue-and-groove slabs made of wooden blocks or a metal channel.

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

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

Any type of wallpaper and painting is suitable for decoration. Kitchen and bathroom are better finished tiled tiles or plastic panels... For the living room, nursery, bedroom, wallpaper or decorative plaster is often chosen.

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

Two ways of installing 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 the tongue-and-groove plate according to the technology involves two types of installation of the partition, depending on the method of abutment:

1. Elastic abutment (fastening). Elastic fastening involves installing a layer of sound-insulating material between the edges of the partition and the walls, ceiling, floor. Cork is an available soundproofing material. 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 abutment (fastening). Monolithic fastening assumes direct contact of partition plates with walls, floor, ceiling through mounting adhesive.

Material for installation of a partition made of PGP (tongue-and-groove plates)

For work you will need:

1. Gypsum tongue-and-groove plate (GWP). Producers: Knauf, Volma, etc. In the size of the GWP, we are interested in its thickness. Plates with a thickness of 80 and 100 mm are common. The number of slabs is calculated from the area of \u200b\u200bfuture partitions with a 10% margin for undercuts. Dimensions of GWP:

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

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

2. You will need mounting gypsum glue. It is sold in 25 kg bags. Tile adhesive can be used for bathrooms. 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 PGP) and C3 (for 100 mm PGP). You can replace the brackets with straight hangers (PP 60/125), used in the installation of plasterboard structures.

4. For elastic connection only! Need a soundproof pad. These are strips with a width of 100-150 mm, better from cork. 5. If the floor is uneven, dry cement mix for leveling the floor at the installation site of the partition.

What thickness of GWP to choose

Interior partitions made of PPG are made in one layer. Technologically, it is impossible to make a straight GWP partition above 3600 mm and wider than 6000 mm. Apartments usually do not have such walls, so there are no restrictions on the use of GWP plates for apartments.

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

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

Tool for installation of the PGP partition

For work, you will need the following tool:

Saw: for cutting slabs;
Drill or hammer drill: For fixing boards and mixing mortar. Drill mixer nozzle;
Notched spatula, width 200 mm;
Simple spatulas: 100 and 200 mm;
The horizontal level is 500 mm and 1500-2000 mm long.
Plumb line for marking the partition;
Rubber hammer for slabs settling;
Clean container for mixing the solution;
Clean water for solution and cleaning tools. Rags.

DIY installation of a tongue-and-groove plate - step by step

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

The base of the partition must be horizontally level. If the slope of the base is visible during measurement, it is leveled with cement mortar. After the solution has dried, it is primed.
Mark the partition along the floor, walls, and ceiling. Use a plumb line or laser level for marking.
In case of elastic (sound-proof) abutment of the partition to the floor, a sound-insulating strip is glued to the installation site of the partition on the mounting glue.

GWP plates can be installed both with a groove up and a groove down. However, for a secure grip, installation with the groove up is recommended.

Therefore, at the slabs of the first row, you need to cut off the ridge with a saw. Do not use power tools for cutting; the amount of gypsum dust will be unreasonably large.
The cut slabs in the partition row should not be narrower than 100 mm. Therefore, before installation, do dry installation and try on the boards in place. If the last board in the row is less than 100 mm, trim the first board in the row.

Install the first row of boards with glue. 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 laying.

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

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

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

Adjoining the PGP partition to the ceiling

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

Adjoining the partition to the ceiling

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 angle 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 sloped void between the ceiling and the slab is filled with assembly glue.

The installation of the tongue-and-groove plate is completed. After installing the partition from tongue-and-groove plates, inspect it, check the vertical level of the partition. With the remaining glue, fill, if any, the voids between the slabs. Peel off excess adhesive squeezed out of the seams.

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

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

Types of tongue-and-groove plates and their advantages

The tongue-and-groove plate differs from other similar materials by the presence of tongue-and-groove 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 considered when building walls.

For the manufacture of gypsum blocks, plaster of paris and special plasticizers are used. This material compares favorably with others and allows you to make high-quality partitions from tongue-and-groove plates. They can be either standard or moisture resistant (green) and suitable for use in rooms with any humidity level.

The main advantages of gypsum boards are: environmental friendliness, high fire resistance, good sound insulation. In addition, hollow blocks can be used to 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 favorably 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 to simply prime it. After that, it can be painted or pasted over with wallpaper.

For the manufacture of silicate boards, water is used, 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 installation instructions

The process of installing walls can be seen on the example of using gypsum blocks. This material is one of the most popular in any renovation 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 firms. This will avoid unpleasant surprises and problems.

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

gypsum plates;
assembly glue;
putty for gaskets;
gaskets (suitable from processed felt or cork);
drill;
mixer;
hacksaw;
level;
rule;
rubber hammer;
roulette;
marker or pencil;
tape or twine;
putty knife;
wedges.

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

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

At first glance, everything is simple: the partition from tongue-and-groove plates is assembled as a constructor, and there are no problems. But there are some nuances to consider.

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", that is, to accept the required humidity and temperature. Secondly, the installation is done with the groove up. The grooves are subsequently filled with putty. Before laying the second row, you need to saw the first slab in two. This is necessary to stagger the vertical joints and impart mechanical strength to the structure. Important: the width of the seams must be equal horizontally and vertically!

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

Here are some tips to help you get the most out of your wall installation:

“There is information in many sources that a partition of slabs can be installed in one day. It is not right. It is best to let the first layer settle for 24 hours and then continue working. " Zoya, doing 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 process of sawing slabs 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 to have cabinets ”, Dmitry, repairing the dacha.

At first glance, tongue-and-groove partitions are perfect option erecting walls and zoning space. However, such material must also have its drawbacks. Information on how to solve problems arising during installation and operation would not hurt. Share your experience with us!

Partitions made of tongue-and-groove plates (hereinafter referred to as PGP) are a prefabricated large-block structure. The blocks are made by molding. They are distinguished by increased accuracy - the deviation of the working surfaces is no more than 1.5 mm from the specified one. Depending on the raw materials used, they are divided into two types:

Silicate. Produced by silicatization of quartz sand and lime in an autoclave under the influence high temperatures... This technology makes it possible to obtain a durable, moisture resistant, nonflammable material.
Plaster. 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, the products 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 may vary from manufacturer to manufacturer. Let's list the most common options:

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

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

Corpulent. They are solid monolithic elements. They are used if you need to provide high strength, for example, to 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 done single or double. If you place 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 foam gas silicate. Moreover, their cost is 10-30% lower.
Security. The raw materials for the production of GWP do not contain any harmful impurities. The products themselves are highly fire-resistant.
Soundproofing. Subject to the installation technology, the wall prevents the penetration of loud sounds into adjacent rooms.
Easy to install. Thanks to the connection individual elements according to the groove-comb principle, even a person without experience in carrying out such work can cope with the construction of a PGP. The main thing is to correctly perform the markup and constantly monitor the straightness of the rule.
Ease. The material is almost twice as light as brick, which reduces the load on intermediate floor... With this, you get more subtle interior partitions, which gives additional usable space.

Disadvantages:

Hygroscopicity. Standard tongue-and-groove slabs absorb moisture well, and can deform during the drying process. Therefore, it is important to install them after completing 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 strengthened well. In new buildings that may shrink, it is imperative to use damping tapes.
Demanding to the foundation. 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 bricks. This means that you have to carefully align all the planes first.

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

The construction of the GWP begins after the end of plastering work, laying of electrical and plumbing communications, but before the installation of rough floors. Humidity should not exceed 60%, and the air temperature should be above 5 degrees.

Foundation preparation

All adjoining surfaces must be level, strictly horizontal or vertical. If the planes do not correspond to the level, we level them with concrete or cement-sand mortar. Dust off the hardened base and prime it.

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 axial plotter, we transfer lines to the walls and ceiling.

You can quickly and perfectly smoothly draw the marking lines with a construction chop cord. It is better to do this together.

To increase noise insulation, we glue the cork elastic gasket with an assembly mortar on all surfaces adjacent to the GWP. We press it with a building level, controlling the correspondence of the vertical and horizontal.

For beginners, a cork lining contour helps to achieve the ideal geometry of the walls. It serves as a guide when checking planes with a rule.

Fastening partitions

Standard fasteners for PPG are staples C3 (with a thickness of 1 cm) and C2 (with a thickness of 0.8 cm). They are screwed with self-tapping screws to the walls, ceiling and wooden floor at the junctions. On concrete floor the necessary strength is created by the adhesive solution.

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

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

Gypsum panels remain stable when erecting rectilinear structures from them with a height of up to 3600 mm and a length of 6000 mm. Distance is measured between intersection angles.

Corner plates must be fixed to each other with punched tape or a plasterboard suspension.

Construction of the first row of tongue-and-groove blocks

After the delivery of the material to the object, it must necessarily lie down for a day. During this time, the temperature and humidity are equalized.

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

We knead a small portion of the adhesive solution. Particular attention should be paid to the time of its viability. It usually takes 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 a level on top and, tapping with a rubber mallet, align the horizontal. Each time, we control the vertical with a small level or long rule for marking.
We immediately remove the excess mortar mixture. When hardened, it will ruin the finish.
If necessary, attach the slab to the enclosing structures.

We repeat the actions for the remaining elements of the first row. We pay special attention to the correspondence of dimensions, straightness and verticality. For control, we use a level, a tape measure and a rule.

Erection of subsequent rows

General principles installation remain the same, but there are some peculiarities. The vertical seams of adjacent rows must not be allowed to coincide. It is necessary to perform them with an interval of at least 1 cm. To do this, cut the block in half. We install one part of it on the whole panel, with which the first row began. We use the second one as an addition.

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

Due to the low pot life of the glue solution, we first cut the parts and adjust them to dry size. 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 with a width of up to 900 mm, you can do without additional load-bearing structures... At the same time, it is important to arrange the order so that there are no freely hanging plates above the door. Therefore, for such places, we first draw a stacking scheme on paper. We start from the row above the doorway. Place the vertical seam in the middle of the span. Only then we paint the rest of the elements, adhering to the rule of the seam spacing.

At the stage of wall erection, we fasten a temporary lintel made of wood or a profile for drywall (installation of supports is allowed). After the adhesive mixture has hardened, remove the temporary assembly 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 within 100-150 mm. The top of the door does not have to line up with the horizontal assembly seam. It is enough to cut the groove for the jumper at the desired level.

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

Construction of the last row of tongue-and-groove blocks

It is inconvenient to finish the laying with narrow trims. 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 the elements to be joined to the ceiling. Clearance is required to install them. To facilitate sealing the seam, 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 in the future you plan to install stretch ceiling, foaming the gap polyurethane foam... When it is important to make an even abutment, fill the hole gypsum plaster... We do this in several steps, observing the thickness of the layer recommended by the manufacturer.

It is important to fix the GWP to the overlap with mounting brackets or corners. Otherwise, the top edge may loosen.

Electrical installation

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

We cut grooves in solid panels with a manual or mechanical chasing cutter. We drill the holes for the socket outlets with wood crowns.

Do not use a percussion tool: hammer drill or impact drill.

We dedust and prime the prepared canals. After installing the cables, we seal the grooves with plaster glue.

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