Frame and frameless cladding of gypsum walls. Options for technical solutions for gluing plasterboard sheets. Sequence of installation work

Like many building materials, drywall came from the USA, where its first prototype appeared in the 19th century. Its appearance immediately solved many problems associated with interior decoration premises. Of course, because facing walls with plasterboard allows you to create perfectly smooth surfaces in almost hopeless places. And of course, this is very good way quickly redesign the premises minimum costs. How to do correct installation and what do you need to know when carrying out such work?

Cladding methods

A huge plus finishing works using drywall is that there are two options for its installation.

Frame method. The classic version and the most common.
Frameless. Less used in practice, however, it has its positive aspects.

What features does plasterboard cladding have in each installation option?

There are only two types of wall cladding with plasterboard: frame - the most popular and frameless

Frame installation of drywall

Most applicable when internal works. Allows you to level walls with large differences and unevenness, while you can hide all sorts of things in the walls engineering communications and insulate the home by laying insulation under the frame.

What will be needed for installation?

Cladding gypsum plasterboard walls on a frame requires certain materials and tools.

Drywall. It can be ordinary wall, moisture-resistant and fire-resistant. Which option to choose depends on the conditions of the room.
Metal profiles and fasteners. The profile is purchased in several types - guides and rack-mount. You also need to purchase hangers (if the frame is hanging) and self-tapping screws for fastening the profile to each other and to the main surface. Don’t forget about attaching the gypsum board sheets to the resulting frame.
Drill (hammer), screwdriver. Without this tool, it is almost impossible to do a high-quality installation of the frame and drywall.
Building level, tape measure, cord - for leveling and accurate measurements.
Metal scissors, grinder. Metal profile cutting tool.
Knife for cutting drywall. You can just get by with a regular utility knife with spare blades.

A more precise list of materials and tools is selected depending on the type of frame structure. There are three main ones:

wooden;
wall-mounted with metal profile;
frame with a profile on hangers.

The wooden frame is easy to install. But the material must be perfectly dried, smooth and without flaws. The slats can be laid both vertically and horizontally. The main disadvantage of such a frame is poor protection from moisture. If you use damp wood, then when the frame dries, it will “pull” the drywall sheets, and as a result, cracks will appear.

Which frame should be mounted, wall-mounted or suspended?

The choice of the type of metal profile frame will depend on how smooth the walls are. If the differences are small, then the wall type can be used. Well, with large (>100 mm) differences, only a suspended frame is possible.

Wall frame

To begin with, before assembly, measurements are taken and the level on the floor and ceiling is marked where the guides of the entire structure will be fixed. Marking is carried out using a marking cord.
Following the mark, guide profiles are attached to the surfaces (according to the UD marking). Their fastening is ensured using dowel nails.
A rack profile (ceiling type CD) is inserted into the guides. For rigid fixation of the racks, self-tapping screws (“fleas”) or press washers are used. The pitch of the racks can be from 400 to 600 mm.
On the received frame structure fasten sheets of drywall using self-tapping screws (the caps are slightly recessed into the sheet).

Frame installation of plasterboard is divided into three categories: wooden, wall and suspended frame

When installing drywall sheets, sometimes you need to cut them to size. To do this, markings are made on both sides of the material. Cutting is carried out using stationery knife, along the line on one side and the other, pressing lightly. To ensure an even cut, it is better to do this process under a ruler or level.
The mounted drywall is subsequently prepared for puttying.

Frame on hangers

This type of construction is used if the differences in the relief of the walls are very significant, as well as when laying communications or insulation. It is important that the insulation should not be pressed down by the frame, otherwise it will lose its properties.

For installation, measure the optimal distance from the walls (usually up to 150 mm) and mark the lines with a cord.
Guides are attached along the lines in the same way as in the wall-mounted version.
Appropriate markings are made on the walls in the places where the frame posts will be located and direct hangers are fixed using dowel nails (their number depends on the height of the room, on standard height 2.5 meters requires four hangers).
Racks are inserted into the guides, to which the hangers are bent, securing them using self-tapping screws. Excess hangers can be cut off or, even easier, folded.
After this, drywall is laid on the frame and firmly fixed with self-tapping screws.

The pitch between screws in drywall is from 250 to 350 millimeters. If you plan to hang shelves, a TV and other heavy objects on the walls, then you need to make bookmarks in the walls in the form of wooden blocks. You can also use a special moth dowel for this.

The suspended frame allows you to level walls with large differences and unevenness

Upon completion of work, the surfaces are prepared for plastering.

Frameless installation of drywall

Cladding walls with plasterboard on glue is the most quick way indoor surface finishing. For this, dry gypsum mixtures are used. The main condition is that the walls must be smooth, durable and not exposed to moisture.

For this type of finishing they use gypsum assembly adhesive. It is available for sale in dry form, packaged in bags.

Frameless installation of plasterboard is the simplest method of cladding

Installation of drywall using the frameless method is carried out in several stages.

Initially, all required communications must be laid.
The surfaces on which installation will be carried out are cleaned of debris and dust, and fragile areas are restored.
Level markings are carried out for even laying plasterboard sheets.
The walls need to be primed with soil with antiseptic additives.
Prepare the adhesive mixture according to the instructions indicated on the package. For good mixing, use a drill and mixer. You should not initially prepare too much glue, as it dries quickly.
If you need to retreat slightly from the wall, then first lay wooden backings, which are then removed.
Gypsum mounting adhesive is applied pointwise to sheets of drywall, which are then pressed against the wall.
To securely fix the sheets, you can additionally add several self-tapping screws. If in the future it is planned suspended ceiling, then such fastening must be done in the upper part.

The glue dries within two days, after which the backing can be removed and further finishing can begin. If various kinds of fastenings are provided for the wall in the future, then in the places where they will be located, you need to coat the sheet with the adhesive mixture completely, over the entire surface.

After graduation installation work begin finishing the drywall using one of the selected methods.

The frameless method of fixing gypsum boards to uneven walls has its advantages. To ensure long service life of the structure, the adhesive mixture and gluing method are selected correctly and the entire process is carried out according to a given algorithm.

How to glue drywall to a wall

Walls and ceilings are covered with plasterboard to level the surface.

To do this, create a frame base from profiles and other materials. However, to level the walls, there is a method of sheathing the walls without a frame. You can learn how to glue drywall to a wall using the right adhesive in this article.

Cladding with plasterboard sheets: advantages

Facing with HA sheets is carried out in the following cases:

surface leveling;
improved heat and sound insulation;
hide wires and pipes;
surface decoration - creating niches, shelves, design decoration figured elements.

The plasterboard sheet has a flat surface; when mounted on a wall, it does not deform, but remains flat. This is convenient for subsequent painting, laying tiles, and wallpapering.

In various rooms with high humidity And high temperature The following types of gypsum boards are used:

An ordinary room with moderate temperature changes is a gray gypsum board sheet.
Wet room: bathroom, corridor in a private house, balcony, attic, kitchen - green leaf GKLV.
A room with a working fireplace, a Russian stove, with a rough stove - pink gypsum board.

On construction market There are types of floor plasterboard and facade plasterboard for outdoor work.

There are methods for attaching sheets to the surface - frame and without frame. In the first case, profiles are applicable. For the second method, you need to choose the right adhesive composition.

Advantages of gluing gypsum board to the surface:

installation is easy and quick;
less expensive method compared to frame;
this method does not take away extra centimeters.

The negative side is the inability to hide wires and communications behind the casing.

When can you glue drywall to a wall without a profile?

Glue sheets can be glued in the following situations:

small rooms where every centimeter of space is important;
the unevenness of the wall is up to 5 cm;
When gluing drywall to the ceiling, you need to select good glue and make additional fixation with self-tapping screws;
finishing of slopes.

In a large room with large uneven walls, the frameless method is not practical.

Is it possible to glue on uneven walls?

One of simple ways level the “falling” wall - cover it with plasterboard on a pre-made frame.

If the difference in wall unevenness is small, the method of gluing sheets is used. To use this technology, you need to familiarize yourself with the nuances and rules.

The type of gypsum and adhesive must be selected in accordance with the humidity and temperature conditions in the room.
The frameless method is applicable if the wall has an unevenness of maximum 5 cm.
During installation, you must follow step by step instructions in compliance with all rules.
To select glue, you need to pay attention to the material of the rough wall.

If you follow all the rules, installing gypsum boards with glue will be easy and will last a long time.

How to choose the right gypsum board adhesive for gluing plaster

Wall covering with plasterboard is carried out by choosing the right adhesive composition. The mixture is selected according to environmental factors. Stroy market offers mixtures:

Gypsum adhesive “Perlfix” from the manufacturer KNAUF or “Volma-montazh”.
Plaster based on gypsum: “Start”, “Finish”.
Gypsum-based putty “Knauf-fugen”.
Tile adhesive "Ceresit -SM 11". This is a cement composition with fillers.
Silicone sealant made of acrylic and polyurethane, “liquid nails”, assembly adhesive mixture. These mixtures are used for smooth surfaces or for gluing sheet to sheet.
Polyurethane foam. Select a composition with a “min” coefficient.

Sealants are mainly used on brick, concrete walls, and foam blocks.

Is it possible to glue it to polyurethane foam?

There are 2 ways to glue a sheet of material to the wall on foam:

First, the gypsum board is attached to the wall with dowel nails, then holes are made and the void under the plaster is filled through them.
Apply foam to the sheet and stick it to the wall.

First method

The material is placed on a flat horizontal surface. 9-12 holes are drilled in it. After the gypsum board with holes is applied to the wall, all drilled holes are marked with a pencil. The holes for the dowels are brightened on the rough coating.

The GC sheet is secured with dowel nails. There is no need to screw in the screw all the way. It is necessary to achieve evenness of the vertically placed material, so when screwing in, use a level. When the sheet is exposed, foam is injected into the holes.

Second method

If the wall is flat, then the foam is applied to a horizontally lying plasterboard. After this, the sheet is applied to the wall, leveled and pressed to force the foam to adhere to the surface.

Polyurethane foam increases 2-3 times. Therefore, the product with the lowest expansion coefficient is selected, and during drying, the condition of the plasterboard on the wall is constantly checked.

Is it possible to glue gypsum boards to tile adhesive?

GKL is glued with tile adhesive, but if the wall has unevenness up to 1 cm. If the unevenness is more than 1 cm, the adhesive will eventually fall off along with the sheet of drywall.

For greater strength, plasterboard sheets are additionally fixed with self-tapping screws or dowel nails.

If you need to make a double covering of gypsum board, then when gluing the first layer, apply glue with a thickness of 0.3-0.5 mm, after complete drying, the same amount of glue is applied for the second gypsum board. A prerequisite is additional fixation with self-tapping screws.

Adhesive for foam block walls

The best option for choosing adhesive for a foam block wall is Perlfix. Holes are made in the HA sheet at a distance of 40 cm with a diameter of 2-2.5 cm. The glue is applied to the wall. After which, the gypsum board is immediately glued. Excess glue will come out through the holes made. It is removed with a spatula. In this way, additional reinforcement is achieved.

Made from polystyrene concrete

Polystyrene concrete - made from cement, foam balls, quartz sand and additives. On a wall made of such a composition it is necessary to use adhesive mixtures cement based with fillers. There is a negative point at the base - it freezes. Therefore, to ensure that the wall finish is held firmly in place, it must be additionally secured with dowel nails.

For wooden walls

Facing wooden walls produced this way:

Treating wood with an antiseptic agent.
Setting beacons for the evenness of the applied sheet.
Holes are made 30 cm from the beacons and a plastic sleeve from the dowel-nail is inserted.
GK sheets are glued to the adhesive mixture. Additionally fixed with dowel nails.

Attention. Before using glue, you need to coat the rough surface with a primer.

For walls made of brick, concrete

GCRs are attached to brick and concrete walls in 4 ways:

Fixation with glue.
Cladding with polyurethane foam.
Using self-tapping screws.
Fixing the dowel-nails.

The choice of method depends on the curvature of the wall and humidity.

Concrete wall. Basically it is smooth - cement-based glue is used. For better adhesion, notches are made on the wall, covered with a primer, and then the gypsum board is fixed.

Brick wall. Fixation facing material produced at polyurethane foam. Applying foam to the sheet with a snake allows you to control the amount of product applied. After applying the foam to the sheet, wait 2-3 minutes. When the foam begins to expand, the sheet is applied to the wall and leveled.

For mounting on a brick wall, polystyrene foam is used. It doesn't expand as much as other similar products.

Preparing a plasterboard wall: what is needed?

To fix the gypsum board to the wall, you need materials and tools:

The selected type of drywall is moisture-resistant, ordinary.
Dowel-nails, self-tapping screws.
Selected adhesive for fixing sheets.
Hammer, construction mixer.
Plumb line, as a rule, sharp knife, level.
Container for preparing glue, spatula.
Primer, roller, brush.

After collection necessary tools, as well as the acquisition of all materials, it is necessary to prepare the rough surface.

Clean the wall of old cladding, wallpaper, paint.
Existing cracks must be reinforced and puttied. Seal all holes with cement or gypsum based mortar.
The surface is coated with a primer.

When the primer dries, prepare gypsum boards. Holes for switch sockets are cut out in them.

For high-quality wall finishing, you need to properly prepare the adhesive mixture:

The specified amount of water is poured into a clean container.
Add a little dry mixture to the water and mix.
After this, add the specified amount of dry mixture and slowly mix with a mixer.

To receive homogeneous mass No need to set the mixer to high speed. This will cause a lot of air bubbles in the solution.

After obtaining a homogeneous mass, pour a small amount of PVA into the glue and mix again.

After kneading, the solution must stand for at least 5 minutes to completely dissolve the additives and obtain elasticity.

DIY gluing plaster to the wall: step-by-step guide

Having prepared the rough walls and mortar for fixing the gypsum boards, you can begin installation. There are 3 methods for gluing sheets:

Apply a continuous layer of glue using a notched trowel. Used for concrete walls.
Applying glue in small piles.
Using beacons and lining foam (gypsum pieces). For very uneven walls.

Each method is applicable according to the evenness of the rough wall.

Sticking the first sheets

A sheet of drywall is placed on long wooden slats opposite the place where it will be fixed. An adhesive composition is applied to the sheet in a continuous layer or in piles.

After this, the gypsum board with glue is carefully lifted to the wall. Wires are threaded through the holes. The sheet is raised above the floor by 10mm - for this you can put a piece of drywall. Place it close to the wall and level it. Evenness is measured by level, diagonally, vertically and horizontally. After installation, the plasterboard is pressed against the wall and checked again for evenness. The glued drywall must be secured with supports.

The second sheet is glued only after the glue under the first sheet has set. Equalization follows it.

Plasterboarding corners

Pasting the wall with finishing material begins with internal corner. Drywall is glued onto the adjacent wall with an overlap.

For pasting external corner you need to measure the distance from the corner to the glued sheet and carefully cut off the measured distance from the whole gypsum board. This cut out part with glue is applied to the corner and aligned with a level and plumb line.

The next cut piece is placed on the corner so that it covers the end of the drywall glued to the 900 corner.

Grouting joints

After covering the wall and the glue has completely dried, it is necessary to carry out a series of work to reinforce the joints. To do this:

Cover the entire surface with primer. All joints are primed with a brush.
After the primer mixture has dried, joint putty is applied to the joints. Reinforcing tape is glued onto it and covered with the same putty on top. If self-tapping screws or dowel-nails were used, then all fasteners are covered with the same solution.
When the putty has dried, grout with sandpaper to remove all small excess putty particles and smooth out the seams.

The last stage is filling the entire surface and priming before finishing.

What can be glued to smooth plasterboard walls?

Plasterboard walls can be decorated to your liking. If these are walls in the bathroom, tiles are glued. If the room has wallpaper or decorative plaster, painting is less common.

Glue drywall to uneven wall You can if you familiarize yourself with all the nuances and rules of work. By following a clear algorithm and choosing the right adhesive, a gypsum plasterboard structure will last up to 15 years.

Leveling walls with plasterboard using the frameless method. Application different technologies to various rough surfaces. Use of supports and struts. Fixation with self-tapping screws, polyurethane foam, installation of beacons.

Drywall without frame on the wall

Leveling the surface with plasterboard is the most popular type repair work, characterized by speed and quality. There are 2 methods of fixing gypsum boards: framed and frameless.

Drywall without frame on the wall - fast budget option, which has its advantages. Methods for gluing plasterboard to the surface, as well as fixing sheets with self-tapping screws, are discussed below.

When is it possible to level walls with plasterboard without a frame?

To level the surface of gypsum boards, the following methods are applicable:

Frame - the use of profiles and components to create sheathing for GC sheets.
Frameless - gluing or directly fixing the sheet to the rough surface.

Fixation of material without a profile is performed in the following cases:

If the walls are crooked by no more than 5 cm.
There is no need to hide wires and communications.
In a small room (toilet, bathroom), where it is not possible to allocate centimeters for the construction of sheathing.

The lathing takes up at least 12 cm of free space in the room.

The frameless method has its disadvantages:

There is no way to hide communications.
There is no way to insulate the rough surface.
In some cases, additional fixation with self-tapping screws or dowel nails is necessary.
The plasterboard sheet becomes heavy with glue applied, making it difficult for one person to lift it. We need to call a neighbor for help.

For relatively flat walls, it is advisable to install gypsum boards using a frameless method.

Existing installation techniques

To fix gypsum boards without lathing, you can use the following methods:

Gluing the material to the rough base using mastic or glue. To do this, a solution is applied at the place of curvature, and it is also applied to checkerboard pattern per sheet. The plasterboard is applied to the wall, aligned and pressed, additionally installing a holder. There should be 10-12 mm from the floor to the gypsum board. To do this, you can put a small piece of sheathing material.
The use of self-tapping screws and foam rubber. This method is used for large curvatures. Fixation is carried out as follows:

make markings for the material;
9-12 holes are drilled on the gypsum board. Their location is transferred to the rough base;
near these holes on back side glue pieces of foam rubber;
The sleeve from the dowel-nail (plastic part) is inserted into the base according to the marks;
The sheet is screwed to the wall with self-tapping screws.

Combined method. Beacons are installed from below and above. The middle is filled with glue.

All methods of fixing a sheet to a rough base are applicable for various surface unevennesses.

Advantages of cladding using the frameless method

The frameless method has the following features and solves the following problems:

leveling surfaces without taking up centimeters of the room;
plasterboard structures improve sound insulation;
the room is being insulated slightly;
relatively quick installation;
budget option - no need to buy profiles and components.

Fixing the gypsum board to the rough surface will be strong only after correct selection adhesive composition.

How to cover a wall with plasterboard without a frame or profile with your own hands

Covering the base without a profile is permissible only with unevenness of no more than 2 cm. To apply this method you need materials and tools:

a set of spatulas with various blades;
level, rule;
container for adhesive solution;
glue mixture;
primer, roller, brush;
reinforcing tape;
putty for gypsum board joints.

After collecting all materials and tools, preparatory work must be carried out.

To do this, the walls must be cleaned of the previous coating - paint, wallpaper, decorative plaster. The entire surface is cleaned of dust and primed.

A plumb line is suspended from the ceiling to determine the overall curvature vertically.

Next comes the preparation of drywall. If the installation is carried out alone, then the sheet of drywall should be cut for convenience. Holes for sockets and switches are cut out in the prepared material. The cut end parts of the material are chamfered using a plane or milling cutter.

On which walls can GVL be installed without a profile?

Installing gypsum boards without a profile is possible using glue if the differences are no more than 2 cm. It is better to apply the glue in “bloops”. They are distributed evenly over the sheet, after which the material with the adhesive composition is leaned against the rough base. It is necessary to align the sheet - it must stand strictly vertically.

After this, lightly tapping the plasterboard, the unevenness of the rough base is filled with glue, the excess goes beyond the boundaries. They are removed with a spatula. The sheet must be fixed with a holder for setting the glue. Only after the composition has hardened do they begin to install the next sheet.

When is it necessary to partially finish walls with wooden slats?

If the base has an unevenness of more than 2 cm, then use a different adhesive method. A grid of wooden slats is mounted on the rough surface. If there are none, then cut the gypsum board sheet into strips 10 cm wide. The strips are glued to the wall using an adhesive composition. We must wait until it dries completely. The gypsum board joints should have strips 16 cm wide - 8 for each sheet. All pasted beacons must be strictly vertical. Leveled.

The evenness of the glued beacons must also be checked using the diagonal rule.

A continuous strip of glue is applied to the gypsum board sheet. It must be located in the place where the beacons will pass.
Drywall swears by beacons glued to the base.

Using wooden beacon slats, the rough wall is leveled and the gypsum board is sewn up.

How to install directly on self-tapping screws: how to screw the sheets

There is another option for fastening finishing material to a rough surface without a frame. This is wall cladding using self-tapping screws. However, this method is applicable when the surface is flat and there are no differences.

There are nuances here:

before fastening the gypsum boards with self-tapping screws, you need to check how easily the fasteners fit into the rough base;
drywall is attached to the wall to improve sound and heat insulation;
It is not necessary to clean the surface before fastening.

Screw the self-tapping screw into brickwork easy. Here the drywall serves as dry plaster for the base.

It is difficult to screw a self-tapping screw into concrete slabs, so dowels and nails are used. They do it like this:

Apply gypsum board to concrete.
They make holes in the material so that there is a hole in the base.
The gypsum board is removed.
The plastic part of the dowel-nail is driven into the concrete.
Place the sheet again and screw in the self-tapping screw, which falls into the plastic sleeve.

The gypsum board is fixed on the wall. For strength, additional holes are created in the sheet and polyurethane foam is introduced through them, serving as glue.

After fixing the drywall to the surface, the joints are reinforced and puttyed.

Do I need to install an additional wall mount?

After fixing the first HA sheet to the rough surface, the adhesive composition should set. To do this, you need to secure the sheet additionally. In order not to keep the sheet near the wall for an hour or more, additional fastening is used:

A homemade wooden device similar to a mop. To do this, the vertical stick must be at least 1.5 m, the horizontal one must be equal to the width of the sheet. The horizontal strip should be smooth so as not to damage the material. It is placed against the fixed material. Moreover, the vertical rail is fixed on the floor (so that there is a stop).
A homemade device made from profiles is the same mop only made from profiles for sheathing under gypsum boards.
Purchased support. Assembled from several parts, which are made from metal pipes. The same device serves as a lifter for the sheet to the ceiling.

If you do not use a support for the material while the adhesive composition is curing, then the gypsum board may not stick or may not be fixed properly and will fall off over time.

Brick wall cladding: features

Brickwork has a number of features that must be taken into account when fixing gypsum boards.

When attaching a sheet with self-tapping screws without glue, once they get into the solution, they will not last long. The building has its own movements, the fasteners will be unreliable.
Gypsum adhesive when applied to cement mortar will not have good adhesion due to the difference in composition. Eventually the glue will peel off.
A brick wall can collect condensation if it is thin and is affected by street temperature changes. Moisture has a negative effect on gypsum boards. In this case, you need to use polyurethane foam and self-tapping screws.

There are two ways to solve the problem of installing gypsum on brick:

In the first case, polyurethane foam is poured into small space between the gypsum board and the base.
In the second, foam is applied to the surface of the sheet, and then it is fixed to the surface. This case is more acceptable, since it is possible to control the amount of foam applied to the surface of the facing material.

Use foam that has the lowest expansion coefficient - for expanded polystyrene.

Installation of facing material with screws and foam:

One sheet is drilled in 9-12 places.
These points are transferred to the surface.
Near drilled holes pieces of foam rubber are fixed to the glue. It serves as shock absorbers during fastening.
Dowels are driven into the wall at the marked places.
The sheet is fixed with screws with wide heads, and washers are placed under them. During installation, evenness must be measured using a level and a rule.
Stepping 1-2 cm to the side from the fasteners, holes are drilled into the gypsum board for foam insertion.
Foam is injected into the hole in small doses. Don't forget - foam expands.

After the foam has dried (about a day), the screws are removed along with the washers. Instead, screw in regular self-tapping screws, “drowning” the caps a little.

Is it possible to attach GVL directly to a concrete wall without profiles?

The concrete wall does not have large differences, so the gypsum boards are fixed with glue.

Gypsum compositions are not used for concrete due to the incompatibility of the included elements. It is better to use acrylic glue.

Before gluing the material, the surface is prepared. Namely:

notches are made on the concrete for greater adhesion;
The entire wall is covered with primer.

After this:

The gypsum board sheet is laid on flat wooden slats in front of the fixation point.
Glue is applied to it with a notched trowel.
The sheet is lifted, a piece of drywall is placed under it so that there is a gap from the floor and it is leveled.
Press it to the base and secure it with a “mop” until the glue dries.
The second sheet is fixed after the first has dried.

If the wall has a curvature, beacons made of wooden slats or cut strips of plasterboard are used.

Before installing drywall on the walls, you should familiarize yourself with the tips and recommendations of the experts:

fixation of the finishing material begins after all the electrical wiring has been done and the floor has been laid;
To install gypsum boards, the room must be moderately damp and the temperature must be at least 10 0C;
the walls must be cleaned of finishing and coated with primer;
For wet rooms we use moisture-resistant plasterboard;
the sheet of glue is heavy, so you need to invite one person to help;
Any glue that comes out must be removed immediately.

Having performed the installation technique correctly, as well as applying the recommendations of the masters, the wall surface will be smooth and ready for further finishing. A plasterboard structure will last 10-15 years if there are no sudden changes in temperature and constantly high humidity in the room.

Drywall is easy to use, inexpensive, convenient and practical material for leveling curved walls, making light partitions from it, suspended ceilings, production of complex cornices and false panels. At self-finishing plasterboard, the sheets are glued to the facing surfaces with gypsum mastics, or attached to a lathing (wooden or metal frame) with self-tapping screws.

Materials

Plasterboard sheets

Plasterboard sheets (dry gypsum plaster) is universal building material, which are rectangular flat panels consisting of a layer of hardened gypsum dough with fillers, and two layers of construction paper (cardboard), which is needed to give greater strength and smoothness to the surface.

Plasterboard sheets are divided into:

Ordinary (gypsum plasterboard). It is used for installation of walls, partitions, ceilings, niches, slopes, boxes.
Moisture-resistant (GKV, GVL, GKLV, GVLV). Used in rooms with high humidity.
With increased resistance to open flame (GKLO). Suitable for rooms with high fire resistance requirements.
Moisture-resistant with increased resistance to open flames (GKLVO). They simultaneously have the properties of moisture-resistant and fire-resistant sheets.

Typically the sheets are 2,500 mm long and 1,200 mm wide. Thickness from 6.5 to 12.5 mm, depending on the purpose of the sheets.

Support frame elements

In the manufacture of frames for fastening drywall, we use various materials. Basically, when assembling frames, metal profiles made of galvanized steel are used.

Metal profiles are divided into:

Guide profile (PN) - used as a guide when installing rack profiles.

Rack profile (PS) is the main element for constructing a frame to which plasterboard sheets are attached.

Ceiling profile (PP) - designed for mounting a frame when installing suspended ceilings.

Wall covering

The internal walls of the premises are lined with plasterboard slabs in order to avoid the need for plastering. This finishing method refers to dry methods. Plasterboard sheets make the walls even, making it possible to hang wallpaper and paint.

Plasterboard sheets are suitable for cladding brick, concrete and wooden surfaces. You can attach the sheets using special mastics, adhesives and self-tapping screws to a metal and wooden frame.

Surface cladding using adhesive mastics

Surface preparation

This method allows you to cover the walls with plasterboard yourself and is suitable if load-bearing frame takes up a lot of space, and the height of the premises does not exceed the height of the plasterboard sheet, since with this method it is unacceptable to create horizontal joints.

To begin with, the surface is cleaned, all uneven areas on the wall are removed, then markings of the installation locations for plasterboard panels are applied to the wall. Also, before preparing, you must complete everything electrical installation work. The room in which work is carried out must first be dried.

Walls are checked by hanging in horizontal and vertical planes, with the further installation of beacons and marks. Beacons (marks) are guides made of gypsum mortar, applied to the wall surface in one plane.

In order to install gypsum beacons, it is necessary to hammer nails into the corners of the wall at the top and bottom so that they protrude 30 mm from the surface. Depending on the height of the room, intermediate nails are hammered. Then stretch the cord horizontally, vertically and diagonally so that it is at a distance of about 18 mm from the wall surface. Beacons with a height of at least 15 mm should be installed under the cord.

Then beacons are installed under each sheet of drywall so that the vertical rows fall on the line where the two sheets join. To do this, the wall is divided into sections, the width of which is equal to the width of the plasterboard sheets. The size of the beacons must be at least 80×80 mm so that the sheet has reliable support. On each vertical line there must be at least 3 beacons, the centers of which are located along the axis of the joint of the sheets, so that the edges of two sheets can be supported on them. In this case, the upper beacon is installed at the ceiling level, and the lower one - at the floor level.

Intermediate beacons are created between the vertical beacons so that the sheet in the center does not bend during gluing.

Gluing plasterboard sheets

There are two ways to glue drywall with your own hands. In the first method, a whole sheet of drywall is placed in the corner of the room. In this case, a sheet placed at the corner of the adjacent wall will form a husk with its edge with the adjacent edge of the first sheet. In the second method, a groove is cut out on the sheet along the center line and bent at an angle of 90°. To do this, use a knife with reverse side cut the cardboard and gypsum core without damaging the front side of the sheet. And then you need to bend the sheet at an angle of 90° and install it in the corner of the room.

First, gypsum mastic is applied to the wall surface within the sheet size. Mastic cakes should be 100-150 mm in diameter and 15-20 mm thicker than the thickness of the beacons.

The mastic is applied in a checkerboard pattern in increments of 350-450 mm. On the edges of the sheet, mastic is applied in continuous stripes. After applying the mastic, the sheet is applied to the wall in accordance with the markings, and pressed with the rule, applying light blows. The mastic squeezed out from under the edges is removed with a spatula.

The installation of the plasterboard sheet should be carried out so that the bottom edge does not reach the floor by 10-15 mm. Before the mastic completely hardens, the sheet must be fixed in this position - for about 30-40 minutes.

Covering surfaces with plasterboard sheets on wooden lathing

To make wooden sheathing, 40 mm thick bars are usually taken, which are pre-treated with antiseptics.

The frame is built in such a way that for each sheet there are 2 vertical bars, which should be located along its edges. If the sheet is wider than 500 mm, then another vertical bar is attached in the middle part of the sheathing. The width of the front surface of the bar, where the joint of two plasterboard sheets falls, must be at least 80 mm.

In places where plasterboard sheets adjoin the floor, ceiling, as well as in places where shelves, mirrors and other heavy objects are attached, horizontal bars are installed. Also, horizontal bars are nailed at the joints of two panels in height.

It is necessary that the front surfaces of the frame bars are in the same plane and are securely fastened, because this determines how the lined wall will look.

Before you start attaching the bars, holes are marked and drilled on the wall. Holes are made in increments of 800-1000 mm. The main difficulty during installation wooden frame is to obtain a flat plane.

To level the plane of the frame, the wall is divided into claws, the dimensions of which correspond to the parameters of the plasterboard sheets. Next, the two outer beams are installed. In order for the beam to stand vertically, it is pressed against the wall and checked with a building level or plumb line. If there are irregularities on the wall that prevent the block from standing vertically, they should be knocked down or cut down.

When securing the beam, you need to make sure that the upper and lower ends fit snugly against the wall in a vertical position. If in the middle part the block takes a concave position, then it is necessary to make a substrate between the block and the wall of the required thickness.

To install intermediate bars, a cord is pulled between the outer ones.

The sheets can be fastened using either nails or self-tapping screws in increments of 400-600 mm. After completion self-installation sheets of drywall, it is necessary to fill the joints and holes from screws or nails.

Wall cladding with plasterboard sheets on a metal frame

Nowadays, when facing with plasterboard sheets, a metal frame is mainly used. This method has many advantages. Installing such a frame is much easier and faster than a wooden one, since special metal profiles are produced for it, and it lasts longer.

The installation location of guides and rack profiles is marked along the floor and ceiling using a plumb line or laser level. Rack profiles are installed in increments of 600 mm.

First, the profile guides are attached to the floor and ceiling with dowel nails, first leveled with a plumb line. Next, the outermost rack profiles are installed, and their position is checked with a level. A cord is pulled between the outer posts and the middle posts are mounted along the resulting plane. To ensure the rigidity of the frame, the racks are attached to the wall with ceiling hangers. The metal profiles are fastened together with self-tapping screws and a press washer.

In places of horizontal joints of sheets, transverse jumpers from a rack profile are installed.

Plasterboard sheets are attached to the frame using self-tapping screws, in increments of no more than 250 mm, retreating from the edge of the sheet 10-15 mm.

Considering these recommendations, you can cover the walls with plasterboard yourself, saving a lot on the services of specialists.

Drywall is a building material that is most often used to level the surfaces of walls and ceilings, which after it remains flat and smooth, suitable for any type of finishing materials.

Structure of a plasterboard sheet: 1 - gypsum base, 2 - plasterboard plates.

Today, two methods of installing this unique material are used: using a metal or wooden frame and frameless method using glue.

The first method is considered more reliable and of higher quality, but it also has some disadvantages, including an increase in cost due to the use of profiles, complexity, and a decrease in usable space, which is especially important for apartments with low ceilings. Installation plasterboard with glue does not have such disadvantages; in this case, the sheets are laid directly on the surface. But there are also some nuances here, for example, such a surface must be previously prepared for installation.

Drywall, or gypsum plasterboard sheets, can be installed in bathrooms where the humidity is quite high. Installation simple and fast, just put your hand and arm yourself simple tools. For greater convenience, you can invite a couple of assistants. It will be more fun, and the work will go faster.

Frameless mounting options

Methods for installing drywall with glue

Frameless installation of gypsum boards can be carried out in two ways, in the first case it is installation on the wall surface with small differences fluctuating in the range of 1-3 cm, and the second method is installation on special beacons. Let's look at these two methods in more detail.

DIY gluing drywall directly onto the wall surface. This method is more complex; it requires certain dexterity and skills, but is not particularly difficult. The procedure is simple: first you need to clean the surface from traces of the old coating, apply markings where the gypsum board sheets will be located. After this, all the tools necessary for the work are prepared, the sheets are cut and the adhesive solution is mixed.

Apply glue in small areas in increments of 15-20 cm (up to 30 cm is acceptable), they should be located around the perimeter of the slab and in the center.

If the ceiling or wall is flat, that is, the slab will fit tightly, then the number of areas treated with glue will not be so large.

Next, the gypsum board sheet is placed against the surface and carefully placed in place. Using a building level, it is necessary to determine the evenness of its installation. When installing on the ceiling, it is more convenient to use a stepladder; you definitely cannot do this without an assistant.

The second method is relatively simpler; it is used in cases where the wall or ceiling has large irregularities of more than 3-4 cm. Here it is best to use the frame method, but if it is impossible for a number of reasons, then installation will be carried out using beacons. To do this, beacons made of strips of plasterboard sheet are installed on the ceiling or wall in increments of 60 cm, which will allow you to determine the level of installation. They are attached to the adhesive solution, which should harden a little, after which you can begin installing the slabs.

This installation of gypsum boards along beacons resembles the frame method of themes; as a result, free space remains under the sheets. The disadvantage of this method is the high consumption of glue, part of which is spent on beacons, and the need to constantly monitor the evenness of the surface. If you have to mount the ceiling in this way, then it is best to immediately use the frame, since the cost in this case of both methods will be the same, and it is easier and faster to install the frame.

Pros and cons of adhesive mounting

Applying glue to drywall is done pointwise over all surfaces of the drywall sheets.

When laying it yourself in this way, you can achieve savings, since you do not have to spend money on metal or wooden profiles or fasteners. There is also no need to pre-assemble the frame or set the vertical position. It is enough to mark the wall, cut the sheets and mix the glue. There is one more, decisive advantage: such a wall is more reliable due to the fact that there are no cavities in it, and cracking at the joints is quite rare.

Using the adhesive method of laying drywall has not only advantages, but also disadvantages. The frameless method is good to use if the surface is relatively flat, but what to do when the ceiling is completely crooked, which is not uncommon in apartment buildings?

In this case, the only option left is to use beacons or preliminary alignment, and this is a large consumption of materials and quite labor-intensive work, not everyone can do it with their own hands. The frameless adhesive method is good for relatively flat walls and ceilings. Of the minuses, it should be noted that carrying out communications under the surface and additional insulation is much more difficult. For cables, you will have to ditch the walls, and the insulation will take up a certain space, and it is best to use polystyrene foam, which not everyone prefers.

General adhesive mounting technology

The technology of laying drywall without a frame, but only with glue, has some features. In this case, not only marking the surface of the wall or ceiling is required, but also preliminary leveling. The marking itself shows where and how the sheets will be located, usually it is a grid with lines that run in 60 cm increments. The technology of gluing gypsum boards itself provides for the installation of large, solid slabs, without preliminary cutting them. But in practice, it usually turns out that not whole sheets (the length of which reaches 3 m) are used, but parts cut into convenient pieces.

Scheme for leveling a wall with plasterboard.

The installation of gypsum boards is carried out in a staggered manner so that there is no intersection of the seams. The boards are glued to the surface using glue, which is applied around the perimeter and in the center of each sheet. But there is one feature that needs to be taken into account. This is the speed at which the glue sets. Often for a beginner who does such installation with his own hands for the first time, this causes a lot of inconvenience, but everything is relatively easy to solve. The working time with the glue mass is about half an hour, that is, do not mix a lot of solution at once, it is better to do it gradually.

Before starting work, immediately mark the surface, cut all the sheets, prepare the tools (two spatulas, a building level, etc.). After this, you can start mixing the glue so you can start working right away. The most optimal amount of glue is about half a bucket. In this case, you can calmly and without haste stick on a large sheet. If the composition is a little lacking, then you can always add it, which is better than throwing out a bucket of already unusable, frozen glue.

The technology for mixing the composition is usually the same, but for some manufacturers it may differ slightly. Therefore, it is best to read the instructions. The consistency should resemble very thick sour cream; if it turns out too thin or thick, you can always add water or a dry mixture.

Do we apply glue to the base or gypsum board sheets?

The question is how to do it right glue drywall is also important. Many experts argue that it is best to apply glue not to gypsum board sheets, but to the base, but this is a rather controversial issue. Glue mixture should adhere equally well to both the material and the base. Therefore, here we can give such simple advice: apply it to the slab around the perimeter and in the center and to the surface of the wall or ceiling. During installation ceiling coverings It is best to apply glue to the ceiling itself, since otherwise the weight of the sheet will become very large and it will be difficult to lift it up. The weight of the slab is about 29 kg, and with glue - all 40 kg, so it will be difficult to lift it even with two people.

Another point that you need to remember when installing it yourself is the primer. Before gluing, the surface of the wall or ceiling should be carefully primed to increase adhesion. The primer will fill all possible unevenness and microcracks, which may not be noticeable at first glance, but have a great impact on the quality of installation.

Today, drywall is a building material that is used for a wide variety of jobs. But most often it is used to level walls; it allows you to create a perfectly smooth and even surface that can be immediately painted, wallpapered, or installed. ceramic tiles. Drywall is easy to install with your own hands; there is no need to have special knowledge or buy expensive tools.

Moisture-resistant plasterboard is a modern finishing material. It is endowed with excellent quality and technical characteristics. The scope of its application is quite diverse.

Advantages

GKLV is environmentally friendly: does not harm human health. This makes it possible to use it in the decoration of any premises. The structure of moisture-resistant plasterboard absorbs moisture 90% less than that of conventional drywall.

The difference between moisture-resistant drywall and regular drywall is that it absorbs moisture 90% less.

It is fireproof because it does not ignite when exposed to a direct source of fire. The sheets can be installed in rooms with high air humidity. They will not be deformed from such exposure. The size of moisture-resistant drywall can be any. This allows you to select its parameters for faster repair work.

GCRs of this type are not afraid of temperature changes. Quite often moisture resistant drywall used for cladding the facade of a building. In this process, the most important thing is to properly treat the drywall surface with protective agents.

In addition, GKLV is endowed with the following characteristics:

Durability - its structure can withstand significant physical and mechanical impacts.
Practicality - the material is quite easy to install on any base.
Versatility - the design of its surface can be done with paints on water based.

Moisture-resistant drywall is considered an excellent heat and sound insulator. You can clean its surface with a damp cloth, but without using abrasives or detergents.

Production

The technological process of manufacturing gypsum boards involves the use of only clean and high-quality raw materials. Certain technical specifications sheets.

The following raw materials are used in production:

Gypsum mixture.
Pressed cardboard.
Various additives.

The latest ingredients are modern components that improve quality indicators.

These include the following:

Waterproof solution - it prevents moisture from penetrating the structure and destroying it.
Antifungal mixtures - protect the surface from the appearance of fungal diseases and mold.
Impregnated impregnation - slows down the process of moisture absorption.

Thanks to the use of natural raw materials and all additives, GKLV plasterboard can be used in poorly ventilated areas.

Moisture-resistant plasterboard is mainly used for finishing the bathroom or kitchen.

Modern specialized equipment is used in the production of the material. Production line has more than 10 machines. With their help, drywall is given certain parameters.

Particular attention is paid to storage technology. The invariability of technical characteristics depends on it.

GCR should be stored in a dry room with a constant temperature. The warehouse is equipped with additional ventilation systems so that dry and humid air masses do not affect the structure.

Types of GKLV

Today, drywall is considered the most popular material for finishing work.

Since it can be used for surface cladding in any premises, manufacturers produce various types GKLV.

How many screws per sheet of drywall may be required and calculations depending on the type of installation

Moisture-resistant gypsum board can be of the standard type or moisture- and fire-resistant. The first type will become indispensable for tiling surfaces in the bathroom, the second - for decorating the kitchen area and fireplace room.

According to the scope of application, the material is divided into ceiling, arched and moisture-resistant wall plasterboard.

Their parameters differ significantly from each other. Wall is used to cover the surface of a wall. Ceiling is suitable for mounting simple and complex structures on the ceiling. Arches and other decorative elements are made from arched wood.

Specifications

During the production process, moisture-resistant drywall is given certain parameters. Also, with the help of additives and special substances, the material is endowed with quality indicators.

The size of a moisture-resistant plasterboard sheet depends on the established standards (GOSTs). The length of the GKLV is 2 - 4 m. The width ranges between 60 - 120 cm. Such parameters allow you to calculate exact quantity material for repair.

The finishing of moisture-resistant drywall does not differ from that of conventional drywall; a primer and putty are used.

The weight of the sheet is not too large and is 9.7 kg/m2. This has a positive effect on the overall weight of the plasterboard structure. It does not create additional load on the rough foundation.

The thickness of moisture-resistant drywall depends on another parameter of the material. With a sheet length of 2 m it can be like this:

6.5 mm;
8 mm;
9.5 mm.

The weight of the gypsum board also varies depending on this technical indicator.

If the sheet length reaches 4 m, then its thickness is 12.5 mm, 14 mm, 16 mm. These parameters do not affect the performance of facing work.

How to distinguish moisture-resistant drywall from regular drywall

When choosing finishing materials you need to be careful. You can often purchase counterfeit goods on the market that do not meet the standards. Its cost is quite low. It is this fact that attracts buyers.

Moisture-resistant drywall, the thickness of which can vary depending on the length of the sheet, is quite easy to distinguish from ordinary plasterboard. In its production, special cardboard is used - it is painted in green tint. The markings are applied in blue. A cardboard sheet of ordinary gypsum board is gray.

There are also differences in the shade of the structure. The gypsum composition of moisture-resistant plasterboard is darker. The edges of the sheet are protected by cardboard. This prevents moisture from affecting the structure.

Features of installation of gypsum boards

Moisture-resistant drywall is mounted using two methods: on a frame or with an adhesive solution. The first method involves constructing a sheathing of metal profiles on the rough surface.

The use of an adhesive solution also has certain limitations. Do not use water-based formulations. In addition, the rough surface for installing drywall sheets must be smooth and clean.

Drywall, otherwise called dry plaster, has received incredible widespread for interior decoration. It is used to level walls, slopes and ceilings, and it is used to build soundproofing partitions, arches, and niches.

Therefore, it would be a good idea to talk about the pros and cons of drywall and find out whether there are any restrictions on its use.

Plasterboard structures

It is clear that even the most quality materials have not only advantages, but also some disadvantages. And in order to understand whether they are suitable for implementing this or that design idea, you need to know which ones exactly.

Advantages drywall

All the positive qualities of this finishing material can be divided into two groups - technical and operational. Let's start with the first ones.

Excellent technical characteristics

We are talking about working with drywall. Many people want to do renovations in their own homes with their own hands, but not all materials are as easy to process and install as drywall.

If we talk about its advantages from this point of view, they are as follows:

Enough simple technology installation Even a beginner will only need one video lesson to understand what's what.
Light weight of the material, the possibility of its installation alone, despite the large area of the whole sheet.

Please note. Even if you need to hem the ceiling, you can do it without an assistant using simple homemade tools.

With certain treatment (wetting with water), drywall can be bent, creating complex structures.

After drying, the material returns to its original strength

It is easy to cut and process, and no complex tools are needed. A knife or a regular jigsaw with a minimum set of functions is enough.
This material allows you to create hollow structures for hidden installation of air ducts, electrical and telephone cables, and pipes. The price of such a gasket is in brick and concrete walls taking into account the device, the groove will be much higher.

All communications remain behind the cladding

Installation of dry plaster takes less time than leveling with conventional solutions, since it does not require long drying.
An additional bonus of this “dry” leveling is the absence of dirt.
Finally, the plasterboard surface lends itself to the most different types finishing from painting and wallpapering to ceramic tiles.

Advantages of operation

If we talk about leveling walls with plasterboard, everyone can find the pros and cons of this method. As for the operation of finished structures, not everyone knows how they are better than plaster or cladding with other materials.

That's why we tell you.

Unlike wood, fiberboard, plastic, and other wall and ceiling panels drywall does not burn and does not release toxins when the air temperature rises.
This is an environmentally friendly material consisting of ordinary gypsum covered with paper.
It's better than cement plaster maintains a normal microclimate in the room.

For reference. Drywall can absorb 15% of its own weight in moisture without losing its performance properties.

Under plasterboard sheets you can place not only communications, but also heat and sound insulating materials, greatly increasing the comfort of the room.

Thermal insulation of walls

Don’t forget about the design capabilities of this material, which allows you to implement the most different ideas, starting from niches and arches and ending with figured ceilings with hidden lighting.
