Interior walls made of tongue-and-groove blocks. How to build partitions from tongue-and-groove slabs (GGP). How to cut material

It was time to erect partitions. Let's start laying the first row. To do this, you will need prepared slabs with a cut tenon. Installing a tongue-and-groove slab with the tongue-and-groove up or tongue-and-groove up is not important, but installation with the tongue-and-groove up is recommended; in this case, it is more convenient to apply the bonding solution to the end of the slab, and a high-quality layer of mortar is obtained, which ensures a strong connection between the tongue-and-groove slabs.

The prepared binding solution is applied to an elastic tape or to the floor surface if the partitions are installed without a soundproofing gasket. The recommended length of the applied mortar (A) with a slab length of 667 mm can be 680...700 mm. When starting the laying of the corner of the partition from PGP (node No. 1), the binding solution is applied immediately under the installation of two slabs (B and C).

Installation procedure for partition corner slabs:

Installation of the plate (B). The slab is oriented according to the markings and the metrostat. The adjustment of the slab, as well as its horizontal alignment, is carried out by tapping its end with a rubber hammer, as shown in footnote 1.
Installing the slab (B) with a sawn tenon. A binding solution is applied to the end of the slab, with which it will adjoin the slab (B), the slab is installed in place and the slabs are tightly connected to each other (footnote 2). All directions of blows with a rubber hammer are indicated by arrows.

After the slabs are installed, remove the excess binder solution and begin to install a nodal connection of the slabs at the site where the partitions are separated (node No. 2).

The connection of gypsum tongue-and-groove slabs at the point of perpendicular connection of the partitions can be carried out as follows. From the corner of the partition (plate B), measure the distance for constructing a doorway, for example, 900 mm wide, and install the slab (D) after cutting off the tenon using a hacksaw.

Afterwards, a solution is applied to the end of the slab and the slab (D) is installed. The installation of these slabs is carried out according to markings and in addition to controlling the horizontal and vertical installation of the slabs, it is necessary to control the internal angle of connection of these slabs, which should be equal to 90°.

There is another way to perpendicularly connect partitions from PGP - without serial ligation. With this method of perpendicular connection of partitions, first, partitions (A) are erected, separating the total area of the bathroom (if we take the example considered in our case), and only after that a partition (B) is erected, separating the bathroom into two separate rooms. This partition is fastened without ligating the rows, by an end connection through a binding solution (B) and additional fastening with steel angles (D) to the wall of the main partition.

Now it is necessary to install the slabs of the lower row of the partition, which is adjacent to one of the walls of the house. To do this, first install a slab (F), which is directly adjacent to the surface of the load-bearing wall of the house. The slab can be installed either with the groove against the wall or with the end where the tenon was. A solution is applied to the end of the slab and pressed with this end against the wall of the house, sealing the joint by tapping the end of the slab with a rubber hammer:

After the slab is installed and leveled, it is fixed to the wall using a steel angle (rigid connection). How to attach the slab to the wall is shown in footnote 3. Throughout the entire work on installing the lower row of partitions, it is necessary to control the horizontal and vertical position of the row of PGP using a building level.

Then continue laying the slabs of the first row to the location of the second doorway. If a doorway with a width of 900 mm is required, and when installing the last slab (3) the distance between it and the slab (E) is less than necessary, then in this case the slab (3) is cut, but it is not recommended to leave the trim for installation in place of the doorway less than 250 mm.

Remodeling an apartment is a common thing; all that remains is to decide on the material and technology for constructing new walls and partitions. We suggest paying attention to tongue-and-groove gypsum boards - a practical, affordable and universally applicable material.

Tongue-and-groove slabs and their scope of application

Tongue-and-groove slabs(GGP) are rectangular blocks of gypsum fiber 80 or 100 mm thick. The size of the slabs is standard - height 500 mm, width 667 mm. To strengthen the connection between the plates, their edges are made in the form of grooves and ridges. The technology allows the construction of up to 4 m 2 of partitions per hour.

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

Preparing the installation site

PGPs are universal in application and can be installed in almost any construction environment. Due to their low weight, they do not require a foundation and can be installed directly on a screed or even on a solid wooden floor.

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

The surface of both the screed and the floor must be coated several times with a deeply penetrating primer, then dried and cleaned. It is optimal to install the PGP before plastering the load-bearing walls, so finishing coating it will turn out more complete.

Damper pad device

To compensate for thermal expansion and settlement of the building, a tape of elastic material is laid at the junction of the partitions with the floor and walls. This could be rubber, balsa wood or silicone tape.

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

Installation of the first row

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

The first row should be laid from the corner. The area where the slab touches the floor and wall is covered with GGP glue, then the block is installed with the ridge up and its position is leveled. It is convenient to use a rubber mallet to move the slabs. Be sure to fasten the first block to the wall and floor using L-shaped plates, the role of which is successfully performed by direct hangers. To use them, you need to cut off the toothed comb from the edges and bring the thickness of the plate to the width of the comb. The plates are first attached to the base using quick-installation dowels with a length of 80 mm, then to the slab with black self-tapping screws no less than 60 mm long.

Subsequently, the slabs are attached through one side: on one side to the floor, on the other - to the previous slab, with a preliminary coating of the joint with a thin layer of glue and strong pressing. To control the placement of slabs according to the project, it is convenient to use lacing or a laser level. It would also be a good idea to mark the partition on the floor and walls indicating the locations for the doorways.

Construction of a partition and adjoining to load-bearing walls

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

To move the joints and remove the edge of the partition, you will need to trim the additional elements to the exact size. It is best to use a regular wood hacksaw with a thick blade and set teeth. If the partition is not adjacent to another wall, its end can be made perfectly flat by increasing the thickness of the glue in the vertical seam from 2 to 6-8 mm.

Arrangement of doorways

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

Openings 90 cm wide or more require laying on top of a series of support beam slabs - 40 mm boards or 70 mm reinforced CD profile. To reach one level, it is recommended to trim the slabs laid on top of the crossbar. The jumper is placed into the partition at least 50 cm on each side.

Corners and intersections of partitions

At the corners and junctions of partitions, it is necessary to strengthen the masonry. To do this, the slabs are laid across a row, alternately covering the joints. In places where the relaying occurs, it is necessary to remove the ridges; they are cut with a hacksaw into sections of 4-5 cm and chipped with a chisel.

The connection can be further strengthened with sections of straight hangers or welded T-shaped elements made of smooth reinforcement. In any case, additional trimming of the ridge to the required distance will be required.

Top row bookmark

When laying the top row, the largest amount of waste is generated due to cutting to the desired height. They can be glued together and placed in voids, since this row of partitions does not experience a strong functional load.

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

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

Interior finishing options

With proper installation of the PGP, the curvature of the surface is no more than 4-5 mm per meter of plane. This is an acceptable indicator for wallpapering walls. The outer corners of the partitions must be protected with a perforated corner profile mounted on starting putty. The internal corners are also puttied, strengthening them with sickle. The joints between the plates are cleaned with an 80 grit abrasive mesh, then the entire surface is coated twice with a high-adhesion primer.

Leveling walls made of PGP can be done with any finishing putty, but the coating will need to be reinforced with fiberglass mesh. Often, puttying partitions is used only to hide seams; as a rule, the layer does not exceed 2-4 mm. The tiles can be laid directly on the surface of the PGP with preliminary priming.

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 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 finished design. 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 of a hollow slab - 22 kg, solid - 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 junction with the main wall, sound insulation in the room is improved;
the pliability of GGP 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 of special glue are required. 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 trim must be removed and large uneven areas smoothed out. 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. They may differ from one manufacturer to another, 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 with a level, corrected with a rubber hammer. For the second row, the first slab is sawn in half to offset the vertical joints. To connect partitions made of tongue-and-groove slabs to the load-bearing wall, brackets are installed at the junction points. 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 a metal channel of the appropriate 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.

Installation of tongue-and-groove slabs is carried out using a technology that has recently been used more and more often by professional builders and home craftsmen. These products have low weight, reliable locking connections and convenient sizes. All this allows you to install them without much effort, remodeling the premises as required by personal preferences.

Types and features of tongue-and-groove products

Before you begin installing tongue-and-groove slabs, you need to understand what types of these products are on the market today. They are silicate and gypsum, the latter are made from the material of the same name, to which a plasticizing admixture is added. For the production of silicate sand, lump and quartz sand are used, which are pressed and kept in an autoclave.

Which slabs to choose

If you want to give your walls heat-insulating qualities, it is better to prefer gypsum boards; they do not allow sound to pass through. However, silicate ones are able to withstand higher mechanical loads and also absorb less moisture. Tongue-and-groove slabs, which can be easily installed with your own hands, are environmentally friendly, so they can be used for furnishing residential premises. The materials are not flammable, do not rot, and do not emit into the atmosphere harmful substances and are not deformed. On sale you can find solid ones that can reduce the weight of masonry by 25%. If we talk about the dimensions of the gypsum boards, they are 500 x 667 x 80 mm. But silicate ones are more compact: 250 x 500 x 70 mm. Once you have dealt with all the supporting structures, you can begin laying tongue-and-groove products, but this must be done before laying the finishing coating on the floor and carrying out finishing work.

Preparation of tools and materials

Installation of tongue-and-groove slabs is carried out after preparing a certain set of tools and materials. These products can be installed in the center of the room, as well as against a wall that goes outside the building or into a cold room. By forming double partitions, you can hide wiring, other systems and communications.

To divide a room into separate zones, you can use partitions, the height of which starts from 80 cm. For installation you will need:

building level;
adhesive composition;
anchor dowels;
gypsum mortar;
spatula;
screwdriver;
cement-sand mortar;
staples for stapler;
felt seal;
primer;
hacksaw;
rubber mallet.

Preparing the site

Installation of tongue-and-groove slabs begins with site preparation. To do this, you should check the evenness of the walls and floor where the products will fit. If there are defects such as sagging, then they should be removed by grinding. The walls and floor should also be freed from cracks and depressions, filling the errors with a cement-sand mixture.

As soon as the bases are dry, they should be coated with a primer. If you decide to install a partition during the ongoing repair process, then the contact lines should be marked on the floor and walls. Afterwards, the finishing coating is cut along the markings so that the base can be seen. For paint, wallpaper, decorative plaster You cannot install slabs; this applies to laminate, parquet and linoleum. If the surfaces have a decorative coating in the form ceramic tiles, then it does not need to be removed, but the surface is first checked for strength.

The tongue-and-groove slab must be installed correctly; to do this, a cord should be pulled between the walls over the entire area, moving it 30 cm from the floor surface. This will allow you to control the vertical placement of the products. Along the contact line it is necessary to stick a sealant, the width of which must correspond to the thickness of the slab. This material can be used as bitumen-impregnated felt or cork backing.

Working on the first row

Installing a tongue-and-groove slab cannot be called a difficult job, but it is necessary to approach this issue with the utmost care. To install the starting row of slabs, it is necessary to cut off the lower ridges using a hacksaw. Glue is applied to the seal, which must be on a vertical and horizontal surface. The first slab is installed on the side where it will adjoin the wall. The perforated bracket is inserted into the groove. The bracket should protrude a few centimeters above the slab. It is fixed to the wall with self-tapping screws, or this is true when you are working on a concrete base.

The slab should be facing upward with the groove, it is leveled and pressed against the base, tapping it with a mallet. In the place where the second slab will adjoin, it is necessary to install a piece of bracket and secure it with dowels to the floor. If it turns out that this product is installed unevenly, then the rest will repeat the angle of inclination. In this situation, it will not be possible to level the masonry; they will interfere locking connections. This explains the need to level the first slab of the bottom row. The composition is applied to the side grooves and ridges so that the seams between the plates are not thicker than 2 mm. Excess mixture should be removed with a spatula, checking the masonry with a building level. A bracket is installed in the lower part and fixed to the floor with anchor dowels. Each subsequent product must be installed after the adhesive composition has set on the previous one.

Installation of the following rows

Installation of walls made of tongue-and-groove slabs involves displacement of the seams in the second and subsequent rows. To ensure this condition, the slab must be cut in half. At the end and beginning of the row, staples should be fixed on the cuts. This must be done in the place where the sections adjoin the wall. The glue should be more liquid; it should be applied to the bottom and side grooves of each product. It is important at this stage to check the vertical and horizontal of the masonry. The next row is installed only after the glue has set in the second row.

Formation of the last row

Usually not accompanied by difficulties. However, it is important to pay special attention to the entire process. For example, the top row should not be adjacent to the ceiling. Approximately 1.5 cm should be left between the plates and the horizontal surface. To do this, staples are installed in the upper grooves of the final row using glue and screwed to the ceiling with dowels. After installation is complete, the gap can be filled with foam, the excess of which is cut off after hardening.

Features of installation of Knauf brand slabs

Knauf tongue-and-groove slabs, the installation of which requires compliance with certain nuances, can be installed by a home craftsman independently. For example, when preparing, it is important to ensure that the subfloor where work will be carried out is stationary, level and stable. If there are unevennesses that exceed more than 10 mm, then it is necessary to form a leveling layer; this can only be done under the partition.

Before starting manipulations, the surface is cleaned of dirt and construction debris, as well as oil stains. To prepare the mixture, pour the dry composition into a clean plastic container with water. The liquid must have room temperature. The composition is mixed using a drill with an attachment or an electric mixer. The solution is left for a few minutes and then mixed again. It is recommended to cook it in portions, one of which you can finish in the next half hour.

Such a tongue-and-groove gypsum board, which is often installed independently, can be installed in one of two ways. The first involves the use of glue, which is applied to concrete base. This method allows you to get a rigid fastening. The composition is applied to the floor and walls in an even layer, and the average consumption for an 80 mm slab will be approximately 2 kg per square meter. If the thickness of the partition increases to 100 mm, then the glue consumption will be equal to 2.5 kg.

The second method involves fastening to walls, ceilings and floors through an elastic cork gasket. This method allows for higher sound insulation, especially for impact noise such as door slams and knocking. Such products are laid with the ridge or groove up. It is more practical to install it on top with a groove, since in this case it is more convenient to lay the glue than to try to spread it on the ridge. If the ridge is located on top, then it should be removed using a hacksaw with large teeth. Sometimes elements are removed using a roughing plane until a smooth surface is achieved.

Features of installation of tongue-and-groove slabs of the Volma brand

The Volma tongue-and-groove slab, which is installed using the same technology as described above, is a product with a total area of 0.33 m2. The plate is made from hydrophobic and plasticizing additives, which are complemented by lithium technology during the manufacturing process. The products are intended for the formation of partitions in rooms and buildings for various purposes with a normal and dry microclimate.

You can control the resulting plane by applying a rule or a regular strip to the wall at different angles. If necessary, the plane can be adjusted until the glue sets. It is important to ensure that the slabs are glued together at four ends. Any excess compound that appears must be rubbed down with a spatula before sealing the seam. You should not begin laying the second row until you have measured the remaining gap for which the section is being prepared. The additional element will become the beginning of a new row. This will allow the vertical seams to spread apart.

You will be able to install tongue-and-groove slabs with your own hands; the tips presented in the article will help you with this. From them you can learn that the slabs must be laid down from the sides and from above; they must be used for this only so as not to damage the blocks. This rule should not be neglected, since otherwise it will not be possible to achieve a tight connection between the tongue and groove.

Adhesive for tongue-and-groove slabs "Fugen"

If you decide to purchase glue for installing tongue-and-groove slabs, then you can pay attention to the “Fugen” mixture, which is offered by the Knauf company. It should take approximately 1.5 kg per square meter. If joints between sheets of drywall are sealed, the consumption will be 0.25 kg. This mixture is a dry composition, which is made on the basis of gypsum and polymer additives.

The solution is intended for sealing seams and cracks. To prepare the dry mixture, pour it into a container with cold water. For 1.9 liters of water you will need 2.5 kg of composition. After evenly distributing the dry mixture, it is necessary to hold it for 3 minutes and mix until a homogeneous mass is obtained. Its consistency should resemble thick sour cream.

Conclusion

If, when laying a partition, you plan to make a window or doorway, then you need to think about the technology for attaching the slabs above it. If the opening has a width not exceeding 80 cm, then the product can be installed on a box or temporary support. This is true provided that there is one row of blocks per opening. If the width is greater than the specified value or there are several rows, then it is necessary to form a strong jumper.

Tongue and tongue blocks are building material which is used for installation interior partitions. They are made from gypsum by low-temperature processing of natural gypsum, which is why their second name is gypsum slabs. This building material is characterized by high dimensional accuracy.

Types of tongue-and-groove blocks

There are ordinary and moisture-resistant gypsum boards. The gypsum board groove can have a trapezoidal or rectangular shape. There are solid and hollow plasterboards. For the construction of walls indoors with dry or normal humidity conditions (apartments, hotels, offices, schools, industrial buildings) use ordinary gypsum boards, and for rooms with high humidity - moisture-resistant gypsum boards. Moisture-resistant gypsum boards contain hydrophobic additives.

Gypsum slabs are a very affordable building material. And thanks to their high quality front surface there is no need to spend a lot of money on finishing work. A plasterboard wall can be covered with wallpaper, painted or covered with ceramic tiles.

Installation from gypsum is very simple and easy. And thanks to the low price, the use of gypsum boards provides a significant advantage over construction interior walls made of brick in apartments or dachas. Another advantage of gypsum boards is their resistance to fire.

How to install tongue-and-groove blocks

In order to build one square meter of partition, you will need 5.5 gypsum blocks and approximately 1.5 kg of glue. In order to enhance sound insulation in the place where the partition adjoins the wall, use a cork gasket. If there are no strict requirements for sound insulation, then the blocks can be mounted to the enclosing structures directly on the adhesive mortar.

First, the surface on which the partition from tongue-and-groove blocks will be built is cleaned of dust and dirt. It is built before the finished floor is installed. Then markings are made using a cord or laser level. The marks are transferred to the walls using a plumb line. If the floor is uneven, you need to apply a leveling layer. Styling can be done no earlier than in a day.

Before starting installation, you need to prepare an adhesive solution, which was recommended by the gypsum board manufacturer (usually it is quite affordable). To do this, pour the dry mixture into a bucket with required quantity water. Then mix thoroughly and leave for 2-3 minutes. It is necessary to take into account that the viability of the composition is only 1 hour, and the glue consumption per 1 m2 of masonry is only 1.5 kg.

Foreman's advice: When mixing glue, use only a clean container and clean cold water.

In order for the blocks in the masonry to adhere better, they must be laid with the groove facing up. To do this, the ridge is removed from the tongue-and-groove blocks of the lowest row of masonry. The laying of the first row is done according to the level and carefully leveled in one plane. When laying the next rows, the glue is applied and distributed along the grooves of the already laid row. The vertical seam of each tongue-and-groove masonry block also needs to be filled with an adhesive solution. The thickness of the seams should not exceed 2 mm. During installation, the gypsum blocks in the masonry are settled using a rubber hammer. Laying is done in staggered steps - at least a third of the length. Additional elements are easily obtained using a manual stove. The elements of the last row of masonry are sawn at an angle so that there are no voids left between the partition and the ceiling.

Foreman's advice: if there are potholes on the tongue-and-groove blocks, they need to be filled with putty.

If you need to make an opening in the partition, the width of which does not exceed 800 mm, and above which there is only one row of masonry, then it is not necessary to install a lintel. In this case, it will be enough to install and leave the support in the opening until the glue dries.

If the width of the opening exceeds 800 mm, then a metal or wooden lintel must be installed above the opening. To give the outer corners of the structure additional rigidity, you need to reinforce them with a metal profile. Internal corners can be strengthened with reinforcing tape.

Installation of gypsum boards can be carried out not only by a professional, but also by a novice builder. At the same time, an experienced worker can make 20 m2 of wall per shift.

Foreman's advice: when attaching objects that exert a light load (mirrors or bookshelves), you can use wedging corrosion-resistant dowels. When installing wall-mounted cabinets or sanitary fixtures, it is necessary to use corrosion-resistant bolts that go right through the wall.

Gypsum slabs are an affordable, cost-effective building material for building walls indoors. To build a wall from gypsum boards, you don’t need special knowledge, you just need to look detailed video laying gypsum blocks.
