How to grind pgp plates. Do-it-yourself installation of a tongue-and-groove plate - step by step. Pros and cons of tongue-and-groove plates

Interior wall partitions, in most cases, are not load-bearing structures in the house. They must have sufficient strength and good soundproofing properties. The design of the partition should easily withstand intra-house communications and hanging furniture.

In this article we will talk about tongue-and-groove gypsum (gypsum) slabs (GWP). This material is used to create interroom and interroom partitions. With a competent approach to the construction, partitions made of tongue-and-groove gypsum boards (GWP) will meet the requirements listed above. But you need to focus on the fact that the installation of tongue-and-groove plates is competent!

If you neglect the observance of construction technology, then the installation of tongue-and-groove partitions will end with the fact that instead of a solid monolith, the builder will get a shaky and uneven wall, ready to collapse at any moment.

At home I have a partition in the bathroom made of tongue-and-groove slabs. Apparently, when a hole was made in it under sewer pipe, Something went wrong. Now, if you shake this structure by the edge with your hand, you can hear the blocks knocking against each other.

On FORUMHOUSE you can find a lot of similar examples. And if the partition was originally built contrary to the existing technology, then defects can be corrected only by completely destroying the structure.

But do not be afraid, because the technology for building wall partitions from PGP is quite simple. And if it is treated with due attention, then the impression of the work done will be very positive.

I've worked in construction. The buildings of the old fund were reconstructed. So, all partitions were made of gypsum tongue-and-groove plates, work is a pleasure. As a partition - that's it. Easily and quickly fit. The walls are even. After puttying, they are ready even for painting, even for wallpaper. The fasteners in the plate hold well. Noise isolation is also normal. But if anything, you can make a crate, lay mineral wool and trim with a trailer or panels.

A little about the practicality of GWP

Gypsum board manufacturers ensure that this material provides secure fastening of standard elements modern interior. This means that GKL partitions can withstand loads comparable to those on walls made of other standard materials. Wall cabinets, household appliances, stretch ceiling- all this is mounted without problems on a tongue-and-groove gypsum partition. It is possible to expand the functionality of a wall partition made of PGP by installing metal-plastic water pipes(with a diameter of not more than 16 mm) and elements of electrical wiring.

And you can also put doors without extensions in the tongue-and-groove, lay the electrician without problems, hang shelves and TV more reliably.

Tongue-and-groove slabs - what is it

Standard GWP are of two types: full-bodied and hollow. The construction of solid slabs is more durable, but this material is significantly heavier than its hollow counterpart. For this reason it is not recommended
use as part of partitions mounted on the floor with
wooden joists.

Hollow GWP provide high sound insulation (43 dB) without overloading the floor structure. Some people believe that all kinds of pests can live and multiply intensively in the internal space of hollow slabs. But such an opinion has not yet been seriously confirmed.

Ordinary (solid and hollow) tongue-and-groove slabs are used for partitions or wall cladding in rooms with dry and normal humidity levels. If the partition is planned to be placed in a room with a high level of humidity, then preference should be given to moisture-resistant plates that have a peculiar greenish tint. Keep in mind that such GWPs are slightly heavier than regular full-bodied products.

Preparatory work

List of tools for working with tongue-and-groove plates:

• Marking cord:
• Hacksaw with a wide blade and a large tooth;
• Roulette;
• Putty knife;
• Drill with a nozzle for stirring mixtures;
• Bucket;
• Building level and plumb;
• rubber mallet;
• Square;
• Screwdriver.

In accordance with the recommendations of manufacturers, the length of the wall partition made of PGP should not exceed 6 m. The maximum height of the structure is 3.5 m. It is possible to increase these parameters, but the maximum strength of the partition is ensured only if the specified dimensions are observed.

The base for the wall of the tongue-and-groove slab must be even, stable and completely free of dust. If the floor is concrete, and there are differences on it exceeding 3 mm, then before starting installation work it is necessary to align it; create a leveling layer. For this, a mortar based on sand and cement is suitable (the mortar grade is not lower than M50).

Alignment of the wall from the GWP.

The solution is applied to a clean dampened floor. To obtain an ideal surface, you can create a kind of formwork and fill it with mortar clearly at a horizontal level. After complete drying, the base must be coated with a primer for concrete.

If you can do without a leveling layer, then the base for the future partition, as well as the junction of the partition to the enclosing walls in 2 layers, are covered with a primer.

If the partition is mounted on a wooden floor, then the base must be reinforced with a strong, even beam.

According to the technology, gypsum tongue-and-groove panels require an even base - a screed or a separate non-flexible beam under the partition.

When the base is ready, you can mark the location of the partitions and doorways. This is done with the help of lacing, a plumb line and a level.

Installation of HGP can be carried out at temperatures from -10 to +30°C. Building material must be brought into the room in advance. This will help him "get used" to the desired temperature regime and insure the partition against deformation (when the temperature changes, the plates may slightly change their volume).

Installation of an elastic gasket

To ensure that temperature fluctuations and deformation of the bearing elements of the building do not lead to the destruction of the partition over time, the HGP structure should be isolated from the base and adjacent walls with a special elastic (damping) tape. The damper tape for PGP protects the wall from mechanical damage and increases the soundproofing qualities of the partition. The elastic tape is a special cork backing (at least 75 mm wide), which we will glue to the base and walls in accordance with the markings. Plates and tape are fixed with the same mounting adhesive.

Consumables intended for installation work (building mixtures, gaskets, dowels, suspensions, etc.) should be selected based on the recommendations of the manufacturer of the PGP. At negative temperatures, the installation of the GWP is carried out using a frost-resistant adhesive gypsum mixture.

Glue with a spatula in a thin layer is applied to the prepared surface. The tape is rolled out from above and pressed lightly with your hands. The adhesive sets within one hour. After this period, you can start building the partition.

PGP installation

The damper gasket under the tongue-and-groove slabs is covered with a layer of assembly adhesive, on which the lower, first row of the GWP is laid. The plate can be positioned with a groove up or a groove down - it does not matter. But if the groove is at the bottom, then the comb will not have to be sawn off so that the plate becomes even. It is allowed to install the upper row of plates vertically (if necessary, due to material savings).

During the laying of the first row, the vertical groove of the tongue-and-groove plate and the base of the floor are smeared with glue. Particular attention should be paid to the observance of vertical and horizontal levels. The plates should be planted with a mallet.

The thickness of vertical and horizontal joints should not exceed 2 mm. After installing the next plate in its place, use a spatula to remove excess glue at its joints.

Additional elements for filling the gaps between solid slabs, walls and openings are easily cut from the GWP using a hacksaw.

The relative displacement of the vertical joints in the laying of the PGT must be at least 10 cm. This is prerequisite to ensure structural strength.

At the intersection of two partitions made of gypsum tongue-and-groove slabs, as well as at the corners, the slabs are laid in such a way that their joints overlap each other. The tongue-and-groove elements that interfere with the correct dressing device should be cut with a hacksaw.

After the partition is ready, its outer corners must be reinforced with a perforated metal profile and puttied.

It is often asked whether it is necessary to glue tongue-and-groove partitions with a sickle. Yes, the inner corners are glued with a sickle and smeared with putty.

Fastening the partition to the wall

The strength of the junction of the partition from the tongue-and-groove to the walls and the base is ensured by the installation of additional elements: mounting brackets, fittings or hangers. It is more convenient to use mounting corners or suspensions. After all, they are attached to the plate with the help of ordinary self-tapping screws, and to the walls - with the help of dowels. Plates of the 1st, 3rd, and 5th rows are attached to the side walls. It is possible more often, but there should be several (at least three) mounts. A strong abutment of the base is created for every second slab.

Direct hangers during installation can be installed directly into the groove of the plate, having previously cut them to the required dimensions.

Between the top row of masonry and the ceiling of the room, you will need a technological gap of at least 1.5 cm. It must be left and foamed with mounting foam. After drying, the excess foam must be cut off, and the seam must be puttied. Between the top row and the ceiling, additional fasteners are installed at the same frequency as below.

Creating doorways

For the device of door or window openings, the width of which does not exceed 90 cm, masonry can be done without additional reinforcement. In this case, an auxiliary structure made of wooden beam, which is removed after the slabs of the top row have been laid and the mounting adhesive has set.

If the width of the opening exceeds 90 cm, then a wooden or metal jumper should be installed above it. The ends of the jumper should protrude beyond the opening by 50 cm on each side. This will ensure an even distribution of the load on the partition.

The door (window) frame is attached to the partition using frame dowels and mounting foam.

Interroom partitions from PGP

Inter-apartment partitions made of PGP, unlike interior partitions, are made double. A technological gap of 4 cm is left between the plates. First, one partition is erected, then the second. In order to enhance sound insulation, the space between the slabs is filled with soundproofing material, mineral wool, etc.

Installation of communications

The design of partitions made of PGP allows you to install hidden wiring. Gypsum boards are strong enough to make vertical grooves in them and have enough thickness to install junction boxes. Technological cavities inside hollow GWP can be used as horizontal strobes.

If the channel selected for laying the wire is expanded with a crown with a diameter of 45 mm, then the cable will pass through it without difficulty. The main thing is not to clog the side hole of the plate with glue during installation work.

In order to make it more convenient to pass the wire through horizontal channels, non-through mounting holes can be made in the side surface of the partition.

Some doubt the safety of vertical chasing of plaster walls. But, according to the manufacturers (and the builders themselves), there is nothing to be afraid of.

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

Properties and characteristics

Often tongue-and-groove plates are used: what is it? This material is a monolithic rectangular slabs of gypsum with an admixture of various additives. The features of the plates are longitudinal grooves and protrusions (ridges) at the joints, providing additional strength to the finished structure. The elements are connected with glue.

Properties of tongue-and-groove plates:

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

For rooms where humidity is high, moisture-resistant GWPs are produced, which differ from ordinary ones in a light green color. In their manufacture, 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

PGP partitions are assembled according to the principle of a constructor, so one person can install about 30 m² per day. Even in the absence of experience, it will not be difficult to understand the process, just read the instructions and look at the photo. The main thing is to correctly mark up the partition. The advantages of the material are:

• when installing partitions from tongue-and-groove plates, 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, the sound insulation in the room is improved;
• the ductility of the GWP joints eliminates the appearance of cracks and deformations;
• the material can not only be pasted over with wallpaper, but also painted, tiled, covered with decorative plaster.

Partition wall installation technology

For 1 m² of a single partition, 5.5 boards and 1.5 kg of special glue are required. Before starting work, the material must be brought into the room and kept 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 a nozzle;
• trowel;
• rubber mallet;
• staples made of galvanized steel;
• self-tapping screws and anchor dowels.

Begin work with cleaning the surface at the junction of the structure. Wallpaper and peeling finish must be removed, large irregularities smoothed out cement mortar or putty. If the wall is even, the paint (plaster) holds firmly, it is enough to remove dirt and dust. Prepare the floor the same way. Next, markings are made on the floor under the partition, the places of the openings are marked. Using a level, the marking line is transferred to the ceiling and walls.

Glue is prepared: water is poured into a container, a dry solution is poured, mixed with a nozzle and allowed to brew for 3 minutes. The proportions for kneading are indicated on the package. They may differ from manufacturer to manufacturer, so read the instructions carefully. A strip of glue is applied along the marking and a cork lining is applied. As soon as the glue sets, you can mount the first row of plates.

A layer of glue is applied to the lining, after which the comb on the long side of the first plate is cut off and installed with this side down. The GWP is leveled, the side cut is coated with glue and the second plate is mounted. Each fragment must be checked by level, correcting with a rubber mallet. For the second row, the first slab is sawn in half to offset the vertical seams. To connect partitions made of tongue-and-groove plates with a bearing wall, brackets are installed at the junction points. One end of the bracket is fixed with self-tapping screws to the plate, placing it in a horizontal groove, the second is fixed with anchor dowels to the wall. The step of such fasteners 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 not more than 80 cm, it is enough to put a temporary support until the glue dries. With a larger width, it is imperative to mount a jumper: a wooden beam or a metal channel of the appropriate section.

The upper edge of the last row of GWP 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 a gypsum mixture or filled with mounting glue. On this, the installation of partitions from tongue-and-groove plates is considered completed. Mounting on such walls of shelves, cabinets, mirrors and other items should be carried out taking into account the load. Up to 30 kg / cm fasteners are made using plastic anchor dowels, at higher values, galvanized bolts are used, passing through the entire thickness of the plate.

Conclusion on the topic

When redevelopment of an apartment, partitions made of PGP are the most profitable solution. In addition to zoning 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 with high quality and accuracy, the partition will turn out no worse than that of professional builders.

The installation of tongue-and-groove plates for the installation of partitions has its advantages. This material has a convenient configuration, relatively low weight, which greatly simplifies the installation work. Also, the plates are equipped with a special lock, which ensures their secure fastening.

Important! The arrangement of interior partitions with the help of tongue-and-groove plates occurs very quickly (almost in a matter of hours). To achieve such a speed of installation, you need to have a lot of experience and perfect knowledge of technology.

The cost of building walls from tongue-and-groove slabs at San Sanych

If you are looking for masters for installing walls from tongue-and-groove blocks, pay attention to our company. We have been working in Moscow for a long time and have received many positive reviews. This happened due to a responsible approach to the performance of all operations. We carefully listen to the wishes of the customer and fulfill them taking into account the requirements. normative documentation. Delivery building materials only trusted companies that provide the best quality at low price. The cost of installation work will definitely pleasantly surprise you. Prices mainly depend on the amount of labor and materials used.

Preparatory stage

Preparing the premises for the installation of tongue-and-groove blocks is as follows:

• the floor and walls in the places where the future partitions fit must be perfectly even. Otherwise, the desired quality cannot be achieved;
• all existing irregularities are eliminated by pouring the screed, grinding. Also, without fail, cracks are closed on the base;
• the surface of the walls, ceiling and floor is primed;
• markings are applied that reflect the location of the future wall.

Block stacking

Before installing the first row of plates that are intended for this, cut off the legs. This will ensure that they are firmly attached to the floor. To fix the tongue-and-groove plates, a special adhesive composition is used. It is applied to all their ends in order to securely fasten them together. Also, a special lock is used for this, which implies the presence of grooves on the surface of the blocks. After installing the first row, it is fixed to the wall and to the floor with dowels. Further installation continues in the same way.

There are quite a lot of building materials for the construction of interior partitions. But not all of them are suitable for use in high-rise buildings. Partitions should be as light as possible in order to minimize the additional load on the supporting structures of the building. Thus, the choice is narrowed down to masonry materials such as tongue-and-groove slabs and blocks.

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

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

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

Blocks or tongue-and-groove slabs?

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

The gypsum block is a regular parallelepiped with smooth edges and right angles. The ideal geometry of products is achieved thanks to a special production technology that does not use high-temperature processing. The blocks have high strength characteristics and excellent thermal conductivity.

A tongue-and-groove plate is the same block with a thickness of 8 to 10 cm, but equipped with grooves and ridges for joining between structural elements during installation. The dimensions of the plates used for the construction of interior partitions are usually 66.7 x 50 cm. Thanks to the “comb-to-groove” joining, the partitions are absolutely even, the displacement of the plates relative to each other is an extremely rare phenomenon.

A partition from blocks will be somewhat cheaper than from tongue-and-groove slabs, the cost of which is higher. And this is only in the case when the installation will be undertaken by professionals who are able to accurately set the blocks along the planes, fix them without distortions and overspending of the adhesive mixture. Such a wall, moreover, is thicker, which means that the sound insulation will be higher. The downside is that the partition will be heavier due to the thickness of the blocks (hollow blocks can be used as an alternative). A wall made of tongue-and-groove slabs will cost more, but its construction does not require an ideal eye and high professional skills.

Preparing to build a partition

First of all, you need to use laser level mark the walls and floor, marking the boundaries new design. High-quality installation of partitions is possible only on a carefully prepared horizontal surface. Therefore, you should start by cleaning the place where the wall was erected. Before pouring a platform for blocks or slabs, the base is treated with a primer for concrete (acrylic, concrete contact or other composition of a similar purpose). It is recommended to apply two layers (the second - after the first has dried).

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

To compensate for thermal expansions and vibrations, a cork substrate (thickness 4 mm, width 150 mm) is mounted on the walls and floor at the points of contact with blocks (plates). This damper tape can be installed on the same adhesive on which the boards will be mounted.

Partition masonry

The laying of slabs and blocks is carried out staggered, moving away from the coincidence of vertical seams by at least 1/3 of the length of the product. The first row of blocks is placed directly on the prepared site. The plates are placed with the groove up, before installing the first row, the comb is sawn off. Glue or mortar with a spatula is spread on the tape (for the first row and blocks adjacent to the wall), then on the block itself. Landing of structural elements is achieved by tapping with a hammer through a bar or a special hammer with a rubber pad. The excess adhesive squeezed out is removed.

Every second row and every second slab (block) of the first row is attached to the walls and floor, respectively, by means of perforated metal corners. For fastening to blocks and slabs, wood screws are used, for walls and floors - dowel screws or anchors. The gap between the top row and the ceiling is foamed and leveled.

It's time for the walls to be erected. Let's start laying the first row. This will require prepared plates, with a cut spike. Installation of a tongue-and-groove plate with a groove up or a tongue up is not essential, but installation with a groove up is recommended, in this case it is more convenient to apply a binder solution to the end of the plate, and a high-quality mortar layer is obtained, which ensures a strong connection between the tongue-and-groove plates.

The prepared adhesive solution is applied to an elastic tape or to the floor surface, if the installation of partitions is carried out without a noise-insulating gasket. The recommended length of the applied mortar (A) with a plate length of 667 mm can be 680 ... 700 mm. When starting laying the corner of the partition made of PGP (node ​​No. 1), the binder solution is applied immediately under the installation of two slabs (B and C).

Installation procedure for partition corner plates:

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

After the plates are installed, remove the excess binder solution and proceed to the device of the nodal connection of the plates at the place where the partitions are separated (node ​​No. 2).

The connection of gypsum tongue-and-groove plates in the place of the perpendicular connection of the partitions can be carried out as follows. From the corner of the partition (plate B), measure the distance for the device of the doorway, for example, 900 mm wide and install the plate (G) after cutting the spike with a hacksaw.

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

There is another way of perpendicular connection of partitions from PGP - without serial dressing. With this method of perpendicular connection of partitions, partitions (A) are first erected, separating the total area of ​​\u200b\u200bthe bathroom (if we take the example considered in our case), and only after that a partition (B) is erected dividing the bathroom into two separate rooms. This partition is fastened already without bandaging the rows, by end connection through a binder solution (C) and additional fastening with steel corners (D) to the wall of the main partition.

Now you need to install the plates of the lower row of the partition, which is adjacent to one of the walls of the house. To do this, first install the plate (G), which is directly adjacent to the surface bearing wall Houses. The installation of the plate can be carried out both with a groove to the wall, and with the end where the spike was. A solution is applied to the end of the plate and pressed with this end against the wall of the house, sealing the connection by tapping the end of the plate with a rubber mallet:

After the plate is installed and leveled, it is fixed to the wall using a steel angle (rigid connection). How to fix the slab to the wall is shown in footnote 3. Throughout the entire work on the installation of the lower row of partitions, it is necessary to control the horizontality and verticality of the row of GWP using the building level.

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