How to build a wall of tongue-and-groove slabs. Installation of partitions from tongue-and-groove plates. Installation of electrical and low-voltage wiring and pipelines

Tongue-and-groove partitions allow you to get a stable flat surface. They are a good alternative to plasterboard walls, they are easy to install and low cost. Thanks to the tongue-and-groove connection system, the joints of the elements become invisible. Due to this, it is possible to omit the puttying stage, immediately prime and proceed to the finishing.

Types of partitions

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

• Silicate are made on the basis of quicklime and water with the addition of quartz sand. The mixture is pressed and kept in an autoclave. They do not burn and have high rates of sound insulation. Compared to gypsum types, such structures are more durable and resistant to moisture.
• GWP partitions are made on the basis of gypsum with the addition of plasticizers. They are divided into moisture resistant (green) and unstable to moisture. The device of such partitions can be performed in any premises, including children's rooms. Gypsum is environmentally friendly, non-flammable, has good sound insulation.

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

Installation of plates for partitions is carried out after the erection of all supporting structures, but before laying the subfloor and before the start of finishing work.

Do-it-yourself installation

Installation of partitions from tongue-and-groove plates is done by hand or with the involvement of professional builders. The material has high thermal insulation, so it can be installed not only inside the room, but also right next to the cold walls in contact with the street.

The installation technology of tongue-and-groove partitions is quite simple. The main thing is to install the structure in level and tightly fix the elements together.

If it is necessary to hide communications without a strobe device, the technology of double partitions is used. The disadvantage is that they take up 2 times more space.

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

Tools

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

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

• felt seal;
• tongue-and-groove plates;
• damper tape, twine;
• cement, sand, gypsum for mortar preparation;
• special glue for tongue-and-groove tiles or glue for tiles;
• primer;
• building level, tape measure;
• pencil, ruler;
• fasteners: self-tapping screws, anchors, brackets;
• rubber mallet, spatula, hacksaw;
• drill, screwdriver, construction mixer.

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

Preparatory work

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

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

When installing partitions during current repairs, markings are made on the floor, ceiling, walls. Mark the location of the partition with a line. All finishing materials are removed from the surfaces a few millimeters wider than the markings show. Strongly adhering ceramic tiles can not be dismantled.

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

Construction of the first row

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

Step by step installation instructions:

1. At the tongue-and-groove plates, which will be located in the first row, the lower ridges are cut off with a hacksaw.
2. Glue is applied to the vertical and horizontal parts of the sealing material.
3. A perforated bracket is brought to that part of the plate groove that will adjoin the wall, so that the fastener protrudes several centimeters.
4. Fix the bracket to the wall with dowels or self-tapping screws.
5. Install the plate up with a groove, press it firmly against the wall and floor, check that it is level, tap with a rubber mallet.
6. From the installation side of the next plate, a bracket is inserted into the groove, attached with dowels to the floor.
7. After setting the adhesive composition, install the next plate, fix it with a bracket to the floor.
8. Each subsequent block is mounted after the adhesive has set on the previous one.

The adhesive composition is applied to the side joints so that the distance between the plates does not exceed 2 mm. The excess glue that has come out is immediately wiped off; after solidification, it will be problematic to remove the streaks.

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

Raising the rest of the rows

The second and subsequent rows are mounted with offset seams. The first plate of the second row is sawn in half. The row starts with half the block. On the sections of the tongue-and-groove blocks adjacent to the wall, brackets are fixed.

The adhesive composition is diluted so that it turns out to be more liquid than the one used for the first row. The adhesive composition is applied to the bottom and side joints of each plate. Using this technology, the entire wall is assembled.

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

Installing the last row

According to the technology, a compensation gap of 2 mm should remain between the ceiling and the blocks of the upper row.

In the upper grooves of the last row, staples are fixed to the glue. Install the block and screw the bracket to the ceiling with dowels. If the slab is larger than the remaining distance, it is cut to the correct size.

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

Technology of installation of partitions with a doorway

When a doorway is provided in the design of the partition, you need to consider how to strengthen the rows that will be above the opening.

If only one row of plates is located above the opening up to 800 mm wide, then it is permissible to mount them on top of the door frame or temporary support.

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

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

Lintels above the doorway:

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

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

Strengthening the corners

In order for the outer corners to be obtained at 90 degrees and not to collapse under mechanical stress, they are reinforced with a perforated corner 3 x 3 cm.

Instructions for fixing corners:

1. Using a spatula, putty is applied to the surface of the corner, a steel corner is pressed against it. Press it along the entire length.
2. If the length is not enough, take another bar and apply an overlap of 3 cm.
3. Apply a layer of putty on top with an angled spatula.

Serpyanka tape is laid along the inner corners. If it is without a self-adhesive base, it is fixed using the same technology as the perforated corner.

The protective layer is removed from the sickle on a self-adhesive basis and glued along the entire length of the corner.

Electrical wiring in partitions

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

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

Stretch wires, connect sockets, switches. Close the holes with putty.

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

Wall decoration from tongue-and-groove slabs

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

It is appropriate to lay ceramic tiles in the kitchen and bathroom. Finishing for the living room and bedroom decorative plaster, wallpaper, painting with water-based paints.

Painting

Before painting, the surface is puttied with fine-grained compounds, which make it possible to obtain a perfectly smooth surface. After drying, rub the surface with a fine grinding mesh. Apply two coats of primer.

Prepare the paint, the desired shade is obtained by adding colors.

Start coloring. The paint is applied with a roller, make sure that the layer is uniform. You may need to apply several coats of paint.

Wallpapering

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

Wallpaper decoration is carried out in the usual way. Dilute glue, cut off a strip of wallpaper of the desired length. Apply glue to wallpaper and wall. A strip is applied, smoothed with a rubber roller, expelling air bubbles.

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

Laying tiles

Finishing ceramic tiles does not require preliminary surface preparation.

Tile laying instructions:

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

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

How to mount tongue-and-groove blocks, you can watch the video:

The partition of tongue-and-groove plates is assembled very easily and is robust design. finishing such a surface can be made with any materials you like.

The appearance of this material was caused by the need to reduce the complexity and cost of masonry.

Judge for yourself - one tongue-and-groove gypsum slab 66.7 cm long and 50 cm high replaces 14 one and a half silicate bricks or 20 pieces of single red (250x120x65mm).

For a silicate tongue-and-groove slab, these figures are more modest (5 and 7 bricks, respectively), but also quite acceptable for speeding up and reducing the cost of work.

Partitions made of tongue-and-groove slabs (PGP) are designed for installation in residential and public buildings with a ceiling height of not more than 4.2 m.

Since such plates have a large side surface and a small width (from 8 to 10 cm), in order to increase the stability of the masonry on the side faces, they make interlock connection"groove-comb". This design solution simultaneously increases the evenness of the partition, since the slab sits exactly on the longitudinal seam and is securely connected to the adjacent one.

Gypsum tongue-and-groove boards

They are made according to the casting technology from gypsum grades G-4 or G-5.

Building gypsum is an environmentally friendly and breathable material. Therefore, partitions made of it comply with strict sanitary and hygienic standards governing the quality finishing materials. To improve the performance and strength characteristics, plasticizing additives are added to gypsum.

Modern gypsum tongue-and-groove boards, depending on the degree of moisture absorption, are divided into ordinary and moisture resistant. To reduce water absorption, granulated blast-furnace slag and Portland cement are added to the feedstock. In order to distinguish such plates from ordinary ones, they are painted green.

Standard gypsum partition blocks can only be used in buildings with dry and normal humidity levels, and moisture-resistant (hydrophobized) blocks can also be installed in wet rooms (according to the requirements of SNiP II-3-79)

Tab. No. 1 Main specifications gypsum tongue-and-groove slabs

In terms of thermal insulation, a tongue-and-groove gypsum board 80 mm thick is equivalent to concrete wall 400 mm thick. Its noise insulation coefficient is from 34 to 40 dB, which is a good indicator for partition structures.

The fire resistance of solid gypsum blocks is very high. They are able to withstand direct exposure to fire for 3 hours (temperature about +1100 C) without loss of bearing capacity.

To reduce the weight of the masonry, hollow gypsum boards are produced in a standard size of 667x500x80 mm. Their weight is almost 25% less than that of corpulent ones (22-24 versus 30-32 kg).

In addition, there is a gradation of gypsum boards depending on the shape of the ridge and groove (rectangular and trapezoidal). However, this parameter does not significantly affect the quality and strength of the partitions.

Silicate tongue-and-groove slabs

The technology for the manufacture of silicate boards consists in preparing a mixture of quartz sand, water and quicklime, which is then pressed and placed in an autoclave chamber. There under the action high temperature and pressure, a strong lime-sand conglomerate is formed.

Silicate tongue-and-groove blocks for partitions have a higher mechanical strength compared to gypsum blocks and a lower level of water absorption. Therefore, they can be used without restrictions for the construction of self-supporting structures of interior walls and for the construction of partitions in wet rooms.

The weight of such a silicate block is 15.6 kg at a density of 1870 kg/m3. Gypsum boards have a lower density - 1570 kg / m3, which has a positive effect on the quality of heat and sound insulation.

Tab. No. 2 Main technical characteristics of silicate tongue-and-groove plates

Silicate boards resist fire better than gypsum boards. They do not emit toxic gases and do not conduct electricity. In addition, the tongue-and-groove lock dampens sound well.

The gas permeability (breathability) of the silicate partition block is at a high level and provides a comfortable indoor climate. This material, even with significant fluctuations in humidity, does not deform or rot.

Manufacturers and prices

The tongue-and-groove blocks produced under the brands Knauf (Knauf) and Volma are in high demand today. The reasons for this are the predictability of their strength characteristics and the high accuracy of geometry. This reduces the cost and labor intensity of finishing work.

Such structures can not be plastered, but, having primed, immediately paste over with wallpaper or paint.

To date, on the building materials market, you can find offers for the sale of tongue-and-groove plates on average from 200 rubles per piece.

Mounting Features

The laying of partitions from tongue-and-groove blocks is carried out after the installation of the supporting and enclosing structures of buildings is completed, before the start of the installation of a clean floor and finishing work.

When redevelopment or reconstruction of residential and civil facilities tongue-and-groove partitions can be built not only single, but also double. The last option is used in cases where it is required to perform a hidden gasket engineering networks or insulate a partition, one side of which goes into a cold room.

At the facility, the installation of tongue-and-groove slabs is reduced to joining at the seams, with periodic control of the verticality and horizontality of each row. When assembling interior partitions, the plates are placed both with the groove down and up. The norms recommend that they be laid with the groove up, since in this case the mounting adhesive mixture is evenly distributed in the tongue-and-groove space.

As an adhesive base for installation, you can use a standard adhesive for aerated concrete or Fugenfüller putty.

Mounting sequence

The base under the partition is leveled with a cement-sand mortar, after which the first row of partition slabs is placed on it according to the level. The surfaces of the groove and crest of each plate before joining are covered with an adhesive solution so that the thickness of the seam at the joints does not exceed 1-2 mm.

Installation is carried out with dressing of the connecting seams. To create an elastic connection to the enclosing and load-bearing structures tongue-and-groove partitions are fixed with special brackets.

The bracket is installed in the groove of the slab and fixed with a self-tapping screw to the floor panel or with an anchor dowel to the building envelope.

In addition, in such joints, the regulations recommend the use of cork or bituminous felt gaskets, installing them around the entire perimeter of the outer joint.

If the width of the doorway does not exceed 80 cm and only one row of tongue-and-groove plates will be installed above it, then the norms allow not to use a jumper. Its role is played by a door frame or a supporting structure, which is removed after curing with an adhesive solution (Fig. 1)

Picture 1

For larger openings installation of a steel or wooden lintel beam above it is mandatory (see Fig. 2)

All areas of contact of partitions with bearing walls and overlaps are sealed with gypsum mortar.

The tongue-and-groove plate is a gypsum rectangle with grooves and ridges around the perimeter. The advantages of a PGP partition in comparison with a brick partition is the speed of installation, which does not require the skill of a bricklayer. The vertical surface of the wall, thanks to the grooves / ridges, will be almost perfect, excluding subsequent plastering. There is also no need to mix a large volume of masonry mortar. For an average partition of 20 squares, one bag of Knauf gypsum mixture is enough. So let's get started.

Marking the first row of an interior partition made of PGP

The most time-consuming is the breakdown of the dimensions of the future partition, the marking of the openings and the scrupulous alignment of the first row, taking into account the horizontal and vertical.

First, prepare all the plates for the first row. We lay out the blocks on a dry one along the entire length of the future wall, check the dimensions, draw a single common line at the base of the plates along the length with a marker, use a laser level.

The slab is placed with the comb up, respectively, the groove in the lower part of the slab is cut down with a pick to the base, then it is polished with a planer for stability.

The part of the plates marked with a dotted line is removed.

Partition masonry

If the floor surface is not even or there is no floor screed at all, it is more expedient to level the first row by installing blocks on a cement-sand mortar, since the gypsum mixture quickly sets. Gypsum mixture(glue) it is better to knead in small quantities for 5-10 plates maximum.

The consistency of the glue, like thick sour cream, is applied with a spatula in a thin layer (no more than 5 mm) along the vertical and horizontal edges of the plate with a quick movement, wiping the glue towards itself with the flat of the spatula. We seal the seams by gently tapping the plate with a rubber mallet. We seal the seams with squeezed glue and cover up minor chips and cracks.

If we start laying the partition with a whole slab, then the next half will go for dressing the seams.

Be sure to fasten it with self-tapping screws to the outer wall through a row and connect the partition of the tongue-and-groove plates with galvanized mounting corners.

The corner is placed for rigidity along the edge of the plate, sinking into the groove with a chisel or a hacksaw. We fix the corner with the next row.
Do not forget to control the verticality and horizon of each slab with a level, correcting the slab or upsetting it, if necessary, using a bar and a rubber mallet.

Gypsum slabs are malleable and are sawn with an ordinary hacksaw when halves, quarters, pieces are needed for doorways, corners or lighthouses.

Work with a hacksaw will be enough, therefore, in order not to bother yourself with endless sawing, I advise you to make a 1.5-2 cm file on both sides. Put the plate with a file on the edge of a stack of plates or a goat, and lifting it up, holding it, release it without effort. The fracture, if necessary, is polished with a planer.

As the barrier is erected doorway instead of a jumper, we overlap with a bar with a thickness close to the width of the plate. We fasten the bar to the GWP with self-tapping screws obliquely.

Door opening device

Depending on the size of the door and the spread of the corners, it is not always possible to make an opening from HWP. Sometimes it is necessary to use other materials to adjust the dimensions. doorway without compromising floor space.

In this case, a brick was used, installed "on the butt" on cement mortar. The ends of each brick are tied with a large nail driven into the slab and fixed with the next brick. Additional rigidity of the structure will be given by the subsequent puttying of the partition with a fiberglass mesh.

Above the jumper, to facilitate the construction, a plasterboard finish will go.

To facilitate the process of arranging the opening, and if the door can be positioned arbitrarily, then we build a solid wall, and subsequently, after a day or two, we cut the opening with a reciprocating jigsaw, focusing on the dressing seams.

We complete the construction of the partition from the tongue-and-groove plates with the last row under the ceiling. We cut the blocks of the last row along 1-1.5 cm less than the required height for foaming with mounting foam.

Conclusion

On the Internet, opinions on GWP partitions are divided. In my opinion, the benefit for the customer is obvious. Subject to the accuracy of the breakdown of the first row, the presence of one's own desire, patience and a partner, a partition made of tongue-and-groove plates with one's own hands can be erected quickly without much effort.

This video shows the process of erecting a partition from hollow Volma tongue-and-groove slabs.

(GWP) is one of the most optimal building materials to create walls and partitions.

GWP is a gypsum block with a groove and a ridge along its ends, thanks to which they are assembled like a Lego constructor. Using this material, you can easily build a partition up to 6m long and up to 3.6m high.

The tongue-and-groove comb can be used in both dry and wet rooms. For the installation of partitions in rooms with high humidity, special moisture-resistant tongue-and-groove plates are made.

Tools and materials for the installation of a partition wall made of HGP

To mount a partition from tongue-and-groove plates, you will need the following materials and tools:

• GWP conventional or moisture resistant
• primer
• mounting adhesive
• gypsum putty
• mounting brackets (straight hangers can be used)
• dowel nails and screws
• spatulas: wide, for outdoor and internal corners
• polyurethane foam
• level
• mallet

You can buy everything necessary for the installation of partitions made of PGP from our company.

Stages of installation of a partition from tongue-and-groove plates

1. Foundation preparation

One of the most important conditions for creating a HWP partition is a reliable and stable base. If the base has strong irregularities, it is necessary to perform a leveling layer using a self-leveling floor.

Before starting the installation, clean the floor from dust and dirt. After that, you can proceed to the installation of the partition.

2. Mounting the partition

To increase the adhesion of materials, it is necessary to process all surfaces that will be adjacent to the future partition primer. After the primer dries, mark and prepare the mixture - can be used any gypsum mounting mix.

To improve sound insulation and prevent other negative consequences, it is better to fix the partition to the base through an elastic porous material, such as cork. This step is advisory.

Tongue-and-groove plates are mounted rows. GWP first row mounted from the wall placement on a layer of mounting mixture. The plate can be installed with the groove up or down. To obtain a high-quality design, it is necessary to check using the level of the vertical and horizontal of the future partition.

Before installing the next slab, apply a layer of adhesive to the already installed tongue-and-groove slab and base. After installing the second and subsequent plates, trim them with a mallet to obtain an even structure.

As a rule, to complete the partition it is necessary to use a non-whole GWP slab. There is nothing to worry about, because thanks to the voids, the material is very easily sawn with a hacksaw.

When laying the second and subsequent rows, it is necessary to observe the vertical joints at least 10 cm This makes the structure more durable.

Constantly control the width of the horizontal and vertical joints to avoid additional leveling steps when finishing the pgp partition, it should be minimal.

Plates necessary fasten to walls and bases: they are performed using mounting corners, dowel nails and self-tapping screws.

The last row must be mounted with a gap not less than 1.5 cm from the floor slab, the remaining gap is filled with mounting foam, after stripping the excess, it is necessary to putty the seam with gypsum putty.

3.Finishing the GWP partition

First of all, it is necessary to protect the outer corners of the resulting partition from mechanical damage; for this, corner perforated profile 31*31. Internal corners are reinforced with reinforcing tape.

A leveling layer of gypsum putty must be applied to all corners.

For gasket electrical wires or wiring accessories, you can use structural cavities, which must be further expanded with a drill with a crown. With the same tool, it is necessary to prepare external holes for wiring accessories and wiring output.

Before applying a decorative coating: wallpaper or paint, it is necessary to clean the seams and treat them and all irregularities with gypsum putty and prime the surface.

The video also reflects the moments of soundproofing partitions and installation attachments: shelves, plumbing.

Advantages of tongue-and-groove plates:

• ease of assembly
• simplicity of openings
• minimum finishing
• does not require plastering
• low price
• high fire resistance

Partitions made of tongue-and-groove slabs have been used in construction for a long time. But my new life they received relatively recently, when life became better, citizens began to carry out repairs and redevelopment of apartments and houses, using modern materials. The latter were not always convenient to use, especially for inexperienced craftsmen who did their own repairs. In this regard, tongue-and-groove plates are better, because their installation is a simple process.

Partitions from tongue-and-groove panels

This wall material for the construction of partitions is present on the building materials market of two types: gypsum and silicate. The first is pure gypsum with the addition of plasticizers. The second is lime mixed with sand, formed into slabs and dried in an autoclave at high temperatures.

Dimensions of gypsum tongue-and-groove plates - 500x667x80 mm. They have higher thermal insulation properties and good sound insulation qualities. Standard sizes silicate plates - 250x500x70 mm. They are inferior in the two parameters indicated above, but much better in strength. In addition, the silicate material withstands moisture loads well. Although we must pay tribute to the manufacturers of gypsum panels, which today offer moisture-resistant boards painted in greenish color. So you can't go wrong when choosing. The dimensions of hydrophobized blocks are 300x900x80 mm.

We add that silicate tongue-and-groove blocks are produced in different thicknesses, which is convenient in terms of selecting material for the partition in relation to the strength of the structure and such an indicator as load bearing capacity designs. Thickness parameter: 70, 88, 115 mm.

In all other respects, the two varieties are owners of almost the same characteristics:

• don't rot
• do not deform
• do not burn
• do not emit substances harmful to humans,
• have a flat surface.

tongue-and-groove slabs

Mounting technology

It is necessary to immediately make a reservation that the installation of tongue-and-groove slabs must begin after the construction work related to the alignment of the supporting structures: walls, floor, ceiling is completed. To carry out the work will have to prepare.

Materials:

• tongue-and-groove slabs,
• plaster glue,
• primer,
• brackets for attaching material to walls and floors,
• screws and dowels.

Tools:

• spatulas,
• building level,
• container for diluting the adhesive composition,
• construction mixer,
• hacksaw,
• screwdriver

Preparatory stage

In addition to preparation necessary materials and tools to prepare the floor. It is already leveled, it remains only to mark the location of the future partition on it, dedust it and prime it. This is always done regardless of the concrete floor or wooden.

With regards to marking, it can be carried out directly on the surface of the floor base and along the walls, drawing parallel lines with a marker or pencil that determine the thickness of the tongue-and-groove plate. Additionally, it is possible to pull a strong thread on one side at a height of 30 cm, which will show the plane of the boundary for installing the first row of board material.

Assembly process

The main requirement for the installation of tongue-and-groove slabs is to correctly lay the first row of masonry, taking into account the horizontal and vertical arrangement of each slab, which will form the basis for the location of the partition. But you have to start with the preparation of glue. It is simply poured in portions into a bucket of water, mixing with a construction mixer. The proportions are indicated on the packaging of the adhesive mixture.

Preparation of the adhesive composition exactly according to the recipe indicated on the bag

On the wall and on the floor at the place of installation of the first tongue-and-groove slab, an adhesive solution is applied in small strokes using a small spatula.

Applying adhesive to the walls and floor at the place of installation of the plates

Now you can install the slab with the ridge up, checking it for horizontal installation using the building level. The panel is pressed against the wall and the floor. A flat floor base is a guarantee of accurate horizontal alignment of the panel.

Checking the tongue-and-groove plate for horizontality using a level

The end of the plate is treated with glue. It is also applied to the floor for the installation of the second element for laying the partition.

The end of the first plate is coated with glue

Both plates are checked by a long rule for evenness in one plane. This must be done, even if board material strictly fit along the marked lines. A slight misalignment can lead to large discrepancies at the end of the septum. So it's better to spend a couple of minutes checking than redoing a large amount of work.

Plates are checked against each other by a long rule

This is how the laying of the first row of partitions from tongue-and-groove plates is carried out with the installation of all elements along the marked lines. Then you can collect the following rows. The installation of the second row begins with a solid plate, which is installed so that subsequently the joints between the panels do not coincide in different rows. That is, the installation is carried out with an offset, preferably half the panel.

The top plate is laid in the second row so that the joint of the two elements of the first row is in the middle

The space between the wall and the partition is filled with a piece of tongue-and-groove plate, which is cut with a hacksaw from a single element. You just need to accurately measure the size for installation.

Tongue-and-groove plates are easily cut with a conventional hacksaw

To strengthen the structure, it is recommended that the plates located near the walls and resting on the floor base be fixed to the supporting structures with metal mounting brackets (brackets), self-tapping screws and dowels. To do this, attach the corner, for example, to the wall, attach it with a screwdriver to the plate with one self-tapping screw, and with the other to the wall surface.

Fastening the tongue-and-groove plate to the wall using a mounting bracket and self-tapping screws

Building a doorway

Installation of partitions from tongue-and-groove plates implies the construction of a doorway. To do this, at the stage of marking, it is necessary to indicate the location of the opening. It is up to him that it will be necessary to assemble the partition: on one side or on two. The main task after assembly is to designate and form the top row located above the doorway. To do this, in two erected walls, it is necessary to make grooves for the embedded beam (lintel). They are simply cut with a hacksaw.

Groove for a mortgage beam

The jumper is placed on the adhesive composition, and the groove is completely filled with it. It is important at the stage of marking the grooves to set them so that the embedded part lies horizontally in them. After that, you can proceed to the installation of plates. Everything is the same here, the timber end of the adjacent wall is coated with glue, after which the tongue-and-groove plates are installed at their destination.

Formation of a doorway by installing tongue-and-groove plates on a mortgage beam

When the doorway is done, you can move on to the last assembly stage- sealing the gap between the partition of tongue-and-groove plates and the ceiling. Usually the gap is not very large, so the easiest option is to foam it with mounting foam. You can use adhesive composition, putty.

Filling the gap between the partition and the ceiling with mounting foam

If you want to bring the wall of tongue-and-groove slabs exactly to the ceiling, followed by fine finish, then on the one hand the gap is smeared with plaster, on the other hand it is filled with foam, and in the same place it is smeared with plaster. Simple foaming is used only when the room, divided by a partition, will be made out with a stretch or suspended ceiling structure.

A partition made of tongue-and-groove slabs is a flat surface that does not need to be leveled with plaster. It is prepared with a small layer of putty, which gives the surface maximum smoothness.

The nuances of the installation process

Any partition is the presence of corners: external and internal. They are subjected to certain loads, in addition, there are always complaints about them in terms of finishing. Therefore, it is recommended to close the outer corners with perforated plastic corner profiles, which will not only create evenness outer corner, but will also be a kind of protection against the appearance of chips with minor impacts.

Use a corner measuring 30x30 mm.

1. A layer of putty is applied to the corner of the doorway of the partition.
2. The corner is pressed into the solution until it stops.
3. Another putty layer is applied on top until it is completely leveled.

For this operation, it is recommended to use an angled spatula. If the length of one corner was not enough, the missing segment is cut 3-5 cm longer than the required length. Because two joined plastic elements overlap.

The problem of internal corners is cracks. You can fight them in one way - with a sickle tape.

1. First, a layer of putty is applied to the corner.
2. A sickle is immediately laid on the not dried solution, which is pressed all the way.
3. Top leveling putty.

Self-adhesive tapes can be used to seal inside corners. When using them, putty can not be used.

If partitions are constructed from several walls, which between themselves constitute broken structure at right angles, then they must be joined together not only with the help of an adhesive composition, but also with the help of the tongue-and-groove blocks themselves. They are installed in perpendicular planes on top of each other. To do this, the crest of the lower panels is cut under the grooves of the upper ones so that the upper blocks fit snugly on the lower ones.

Rules for joining tongue-and-groove panels at the junction of two walls

If a partition of tongue-and-groove blocks is assembled on concrete floor, then fasten it to the base with metal brackets, there is no need. Adhesive composition - a guarantor of strong fastening. If the floor is wooden, then you can not do without mounting corners. In this case, you can even not use glue between the blocks and the floor.
