Plasterboard sheets (GKL) are an excellent substitute for the usual method of leveling walls - plaster. The article discusses the main methods of using this material.

Plasterboard wall covering

Plasterboard sheets are produced in sizes 1200*2500 mm, thickness varies from 6.5 to 12.5 mm. The technical characteristics of plasterboard allow it to be used for interior decoration in all rooms. There are types of drywall with increased moisture or fire resistance.

Interior finishing with plasterboard: advantages and disadvantages

Cladding walls and ceilings has a number of undeniable advantages:

• the ability to hide communications under sheets, such as electrical wiring or heating pipes;
• the ability to level even very uneven walls;
• high installation speed;
• Mineral wool can be placed in the voids between the wall and the sheathing to increase sound and heat insulation.

Significant disadvantages include the higher cost of materials and work relative to plaster, and the inability to hang heavy objects without prior preparation.

Sheathing methods

GCR surfaces are decorated in 2 ways:

1. According to the frame.
2. Directly on the wall or ceiling.

The frame is usually made of galvanized metal thin-walled profile, but it can also be made of wood. When fastening sheets without a profile, special glue and dowels with self-tapping screws are used.

GKL sheathing on a frame: technology

When attaching material using a frame, it is very important to mount it correctly.

• The guides attached to the walls must be strictly vertical, as well as the intermediate racks.
• The distance between the centers of the posts should be 600 mm, i.e. such that the joint of the sheets falls on the profile.
• To strengthen the structure, you can reduce the size to 400 mm.
• If it is necessary to join sheets vertically, install a horizontal profile to tie 2 sheets together.
• Drywall is attached to a metal frame with black metal screws, 25-32 mm long, and to a wooden frame - with wood screws of the same length.
• To improve the strength and insulating properties, lining with sheets in 2 layers is possible. In this case, the sheets are sewn in checkerboard pattern.

How to sew drywall without frame

GCR without using a frame can be fixed with special glue or mechanically, using dowels and self-tapping screws. It is possible to combine these 2 methods by first securing the sheets to adhesive composition, and after it dries - onto the screws. At the same time, it is important to fasten the drywall with hardware in those places where the glue is applied, and not between them, because the coating can be deformed and even broken.

GCR decor

Plasterboard walls and ceilings are painted, covered with wallpaper, plain or painted, and finished with decorative plaster compounds. The walls are tiled tiles, decorative bricks, stone, etc.

Suspension

Only light objects, such as photographs, decorative shelves, and lightweight mirrors, can be hung on plasterboard walls. To screw self-tapping screws into gypsum boards, special dowels are used: driva, molly or “butterflies”. Provided that the location of the profile is known exactly, you can tighten metal screws for hanging various items directly into the frame elements. For attaching heavier objects (cabinets or bookshelves), it is necessary to arrange special mortgages.

Do-it-yourself profile mounting technology on walls

To install a false plasterboard wall, you will need the following tools:

• Tape measure, square, pencil.
• Level.
• Plumb.
• Thread (lace).
• Metal scissors or grinder.
• Hammer.
• Screwdriver.
• Pliers.
• Profile cutter.
• Construction knife.
• Planer for drywall.
• Spatula.

Materials:

• Guide profile PN.
• PS rack profile or PP ceiling profile.
• The suspension is straight.
• Single-level connector (crab).
• Dowels.
• Self-tapping screws for wood and metal, black.
• self-tapping screws for thin plates with a press washer, pointed (bugs).
• Damper tape.
• Serpyanka tape or paper tape for joints.
• Putty.

Methods of fastening with dowels: how to install

A damper tape is attached along the perimeter of the future wall, and a guide profile is placed on it. The frame element is installed on the floor in the form of an inverted letter “P”, secured with self-tapping screws to wooden floor or with dowels and screws for concrete. After that, the guide is attached to the ceiling strictly vertically above the floor profile, then the guides are attached to the walls.

Strict verticality must be observed, unless otherwise provided by the design.

How to choose fasteners for brick, concrete and wooden walls

To attach hangers and guides to the walls, you may need various hardware, depending on the material of the walls. Frame elements are attached to wooden walls with wood screws. For installation on brick or concrete surfaces You need to use dowels with self-tapping screws or dowel nails. The use of dowel-nails increases the speed of work, but they are more difficult to dismantle if necessary to remake the structure

How to mount and lay the profile correctly

After installing the guides around the perimeter, mark the location of the rack profiles. Usually they are placed at a distance of 600 mm between centers, so that the vertical joints of the sheets fall exactly in the middle of the profile. To give the frame greater rigidity, reduce the distance to 400 mm. Vertical lines are drawn from the obtained points, and straight hangers are attached to them in increments of 400-500 mm. Insert the rack profile cut to size with its ends into the guides on the floor and ceiling.

The rack profile should be cut 5-6 mm shorter than the distance between the floor and ceiling.

The rack profile is set vertically and attached to the guides with “bugs” or using a cutter, then attached to the hangers, constantly checking the verticality using a level. When all the profiles are secured, you should check the plane using a rule, a long level or a thread. Deviations from the plane of more than 2 mm should be corrected.

At the places where the sheets meet in height, additional horizontal profiles are installed. It is recommended to arrange such joints at the bottom of the wall.

How to screw gypsum board sheets to a frame: installing drywall on walls

Plasterboard sheets are secured using metal screws 25 mm long. The sheet is installed in place, secured to 1 screw, then adjusted to the level and secured to the rest. The fastening pitch should be approximately 200 mm or more often. The hardware is twisted so that the head is flush with the surface of the sheet without breaking through the paper.

The sheet must be fastened in one direction, for example, from left to right, from bottom to top. If you fasten the sheet in different corners, it may bend during further fastening.

First, whole sheets are attached, then parts are cut to size and the remaining parts of the wall are covered. The edges of the cut are processed with a drywall plane.

Before sewing up the wall with sheets, you can lay sound and thermal insulation materials, wiring.

Grouting seams and dowel holes: how to finish them

Seams with a factory chamfer on the wall are taped with sickle tape or paper tape for joints. Seams without chamfer are cut using construction knife. The surface is primed. Seams and recesses from self-tapping screws are puttied with gypsum-based putty mixtures. As a rule, the packaging of the material indicates whether it is suitable for sealing gypsum board joints or not.

Cladding and finishing the ceiling in an apartment yourself: what you need

To install a gypsum board ceiling you will need the same tools as for walls. Additionally, you will need a hydraulic level or laser level, a coated marking cord and a T-shaped stand made of bars or profile. It is more convenient to carry out all work on the ceiling with a partner.

How to attach to a concrete base on the ceiling

The locations of the ceiling profiles are marked on the ceiling. They are usually placed along a short wall with a pitch of 600 mm. The most convenient way to do this is with a coated cord. Then the hangers are attached to dowels with self-tapping screws or dowel-nails. If the ceiling is lowered to a significant distance from the draft, you need to use special hangers, similar to Armstrong ceiling mounts.

Fastening the guides

Mark the mounting location using laser level or hydraulic level, marking points at the corners of the room at a given height, usually as close as possible to rough ceiling, and drawing lines using a marking cord. A damper tape is attached to the wall, then guide profiles. A gypsum board ceiling can be lowered for laying insulating materials or installing communications.

How to hang sheets correctly

The gypsum boards are attached to the frame, starting from the corner, with the long side along the short wall, parallel to the ceiling profiles on the plane. The most convenient way to fasten the sheets is to support them with a special stand, which you can purchase in a store or make yourself from a block or profile in the shape of the letter “T”. It is recommended to use moisture-resistant gypsum boards.

Do not release the sheet until it is secured with at least 15 screws.

Cladding uneven walls with your own hands: what is worth remembering

When covering walls, it is important to maintain verticality and ensure that the profile does not deviate from the plane. If the gypsum board is attached to a wall without a frame, it is important to attach the screws in places where the sheet will not “walk”, otherwise the screws will protrude on the surface. Before covering the walls, it is advisable to sweep or vacuum them and the space behind the frame; it is also recommended to prime them to avoid the appearance of dust.

How to install faster

To increase the speed of installing drywall on the wall, you need to correctly mount the frame and secure the first sheet without deviations in level. Most quickly, such work is carried out by two or three people, when one person is busy installing the sheets in place and cutting them to size, and the remaining 1 or 2 people are busy pulling them through with self-tapping screws. The use of professional screwdrivers with belt feeding of hardware significantly increases the speed of work.

What can be mounted on a plasterboard wall?

With appropriate preparation, almost any objects can be mounted on gypsum board walls, including cabinets and storage water heaters. To do this, during the manufacture of the frame, so-called embedded parts are made of plywood or boards. Lumber is sewn onto the rough wall so that the front surface of the embed is in the same plane as the frame. If the mortgage is deeper than the frame, the wall will push through when attaching hanging objects.

How can you cover plasterboard sheathing?

After sealing the seams and holes from fasteners, a gypsum board wall can be painted or covered with wallpaper, covered with decorative plaster, covered textile wallpaper. It is recommended to cover surfaces made of moisture-resistant plasterboard with a continuous layer of putty, otherwise green can be seen through finishing coat.

The walls can also be covered with tiles, decorative stone or brick, stucco, panels. It is not necessary to treat seams and marks from self-tapping screws before cladding.

Drywall is a modern finishing material that allows you to produce finishing work with minimal labor and time costs.

Useful video

Modern and reliable material, drywall has firmly entered the top ten most popular building materials. And it is no coincidence, because finishing walls with plasterboard allows you to re-imagine already familiar walls and the entire interior of the room, as well as make the room more comfortable and functional. The qualities of this construction and finishing material allow you to perform many works with drywall yourself. After all, its ability to take almost any shape, plasticity, and resistance to many influences ensures the preservation of beauty in the room for a long time.

General scheme of wall covering with plasterboard

Finishing walls with plasterboard with your own hands is quite possible. However, the basic rule should be observed: strictly follow the sequence of actions. Only in this case the result will be exactly as expected, and it will last for a long time. Therefore, let’s consider what the algorithm of actions is when working with this popular material when doing wall cladding with your own hands.

Conventionally, the entire process of covering walls with plasterboard can be depicted in five sequential operations:

1. Selection and preparation of materials that will be required for wall cladding.
2. Marking the wall surface that will be decorated with plasterboard.
3. Installation of the frame onto which the material will then be attached.
4. Frame covering.
5. Rough version of finishing using plasterboard.

The following five points are required to obtain perfect result when decorating a wall using such a universal material as drywall.

Now let's study in more detail what each step is and how to perform it correctly.

Wise choice of materials

There are several types of drywall. This material can be used in different jobs for construction and finishing of premises. And depending on the type of room in which drywall will be used, the requirements for it will vary. After all, he may have various characteristics, determining the possibilities for its application.

The most important parameters by which you should approach the choice of drywall when deciding to cover walls with it include:

• thickness. There are several varieties of this material for interior work, which vary in thickness. And for wall cladding, a material with a thickness of 12.5 mm will be considered optimal;
• moisture resistance. When upholstering the walls of rooms in which there is high humidity, the only possible option would be to use drywall marked “KGLV”. This material is suitable for rooms such as toilets and bathrooms, storage rooms, if the humidity level here may increase. For other, “dry” rooms, it will be normal to use ordinary drywall.

You will also need other materials to decorate the walls. At the preparation stage, they should also be stocked in required quantity. These will be:

• primer;
• elements for arranging the frame. This includes guides, PN and PS profiles, as well as self-tapping screws and direct hangers;
• serpyanka mesh;
• There are two types of putty – starting and finishing. Finishing putty will be necessary only if it is planned to paint the wall after completion of the work.

Types of profiles for drywall

In addition to the materials listed, you will also need certain tools. They will allow you to carry out all the work on covering the wall with plasterboard to the highest quality. For this job it is recommended to have:

• masking tape;
• rule;
• a set of spatulas of various sizes;
• an electric drill or screwdriver of sufficient power;
• metal scissors or grinder;
• cuvette;
• roller;
• building level;
• mesh (preferably a set) for grinding.

This minimum of tools will allow you to complete the work of decorating the wall with plasterboard with maximum convenience and quality.

After preparation necessary materials and tools, you can start working directly.

Marking on the wall surface

Marking is carried out in order to obtain a perfectly flat surface. It must be performed before starting work on laying gypsum board.

The execution diagram looks like this:

1. A line is drawn on the ceiling along which the supporting profile will be attached. Drywall will be fixed to it. The location of the line is at least 40 mm from the wall surface. If the wall that will be decorated using of this material, will be insulated, then the thickness of the insulation should be added to 40 mm.
2. The resulting line on the ceiling should be transferred to the floor surface. To do this, you can use plumb lines. And also the construction level. With its help on two opposite walls vertical lines are drawn to the floor level. And the resulting points are connected by one line.
3. Now markings are applied to the surface of the walls. To do this, mark the attachment lines of the PS profiles, onto which the drywall will then be fixed. To do this, draw vertical lines at a distance of 10 cm from the corners. The pitch of these lines (that is, the distance between them) should be 60 cm.
4. Now, along the resulting lines, you should mark the places where the suspensions are attached. To do this, additional horizontal markings are made every 50 cm.

The given sequence of steps must be carried out on all walls that are planned to be finished with plasterboard. This will allow in the best possible way place the frame and then fix the drywall.

Execution of the frame

Leveling the walls with plasterboard with a frame with your own hands makes it possible to get perfectly even, beautiful walls. Any finishing touch will look great on them: painting, wallpapering. The frame installation process is quite simple. And the following detailed step-by-step instructions will help you do it yourself:

• All guides are pre-cut to the length of the wall on which they will be attached;
• Then, using dowel-nails, guides are attached to the walls and ceiling. These are the nails that will provide maximum reliable fastening and long-term preservation of the material on the surface of walls and ceilings that are covered with plasterboard. If the walls that are sheathed are made of foam blocks, then in addition to dowel-nails, the use of special fasteners for foam blocks will be required. This way the grip will be the strongest and most durable;
• Now the PP profiles are cut to the required sizes and fixed into the guides. They are fixed in hangers. It should be remembered that profiles tend to sag slightly. Therefore, it is necessary to align them regularly using the rule;
• Now, by attaching the jumpers, the necessary strength of the resulting frame is created. To do this, the transverse jumpers are cut together and arranged in a checkerboard pattern.

This method of fastening them allows you to obtain the most durable and flat surface.

Professionals give good advice: in order for the resulting surface of the frame to be smooth, you should initially install corner guides and connect them all in pairs using a cord. This will result in straight lines along which, like beacons, you can attach the remaining profiles.

The given sequence of actions is applicable when covering walls using plasterboard. In the same way, it is necessary to cover all surfaces that will then be covered with this material.

Owners of houses made of wood should especially pay attention. Because this one is environmentally friendly natural material prone to rot and mold, especially in rooms with high degree humidity, it is recommended that before installing the frame, thoroughly treat the walls and ceiling with special antiseptics. They will perfectly protect the wood and prevent its premature deterioration. And only after the wood has completely dried can you install the frame and cover the wall with plasterboard.

We cover the frame

Now we proceed directly to covering the resulting frame with plasterboard. Depending on the type and size of the wall being sheathed, preliminary cutting of sheets of material is carried out. The process of cutting drywall is quite simple. For this, there is also a simple algorithm of actions that allows you to obtain individual parts of the required size and shape.

This algorithm looks like this:

• several points are applied to the surface of the sheet in accordance with the dimensions required for a separate section of the wall;
• points are connected by straight lines using a rule;
• when using a mounting knife, a part of the sheet of the required size is cut;
• Now the sheet is folded and the cardboard is cut along the fold line.

The resulting sheets are fixed to the required place on the wall using self-tapping screws. This process simple, does not require special skills and abilities. However, you should remember some points that will allow you to get the most even surface of the sheathed wall:

• The edges of the drywall should be exactly on the center line of the profiles. This will make the sheathing as neat as possible, since it is the overhanging edges that begin to crack and crumble over time;
• location of screws - step of at least 25 cm;
• The caps of the screws should be carefully “sunk”. This will allow further processing the resulting surface with the highest quality. After all, protruding caps will interfere with further finishing of walls that were covered with plasterboard.

Plasterboard lathing is performed on all types of floors. However, when finishing frame buildings with this material, you can do without lathing. In this case, sheets of material are attached directly to the walls of the building. The resulting wall finishing with plasterboard without frame and profile on frame buildings holds up well without disturbing the geometry of the premises and giving them a more attractive appearance.

We carry out rough finishing

After installing the plasterboard sheets to the frame, it is rough finished.

First, a chamfer is cut from sheets of material. Its width should be about 5 mm. If the corners of the sheets are rounded, then there is no need to chamfer. Serpyanka is glued to the joints. Using a primer and a paint roller, the joints are processed to level the surface.

Puttying of plasterboard walls is carried out in order to eliminate the slightest irregularities, since during finishing they become noticeable and reduce the value of the final result.

After the treated surface has completely dried, a starting layer of primer should be applied. A paint roller can be used, and in particularly difficult to reach places - paint brush. Particular care should be taken in places where there are depressions from the screw heads.

Plastering plasterboard walls is carried out as a finishing coating. She represents decorative coating, which may have different texture, different shade. The more even the layer of soil was laid, the more neat and beautiful it will look. decorative plaster on such a wall.

Drywall firmly occupies the position of one of the most popular among construction and finishing materials, and this is easily explained by its many advantages. These include its environmental friendliness, ease of installation, the ability to use in the most different rooms, relatively small weight and generally available cost.

Plasterboard sheets are used for leveling walls and for, and, moreover, working with them is possible not only an experienced builder, but also for the beginning master. Finishing walls with plasterboard without a frame and profile is possible with different adhesive compositions and on surfaces made of various materials. The advantages of such fastening compared to frame method are that the reduction in the area of ​​the room is not so noticeable, a decent amount is saved on the elements of the sheathing, and the installation work pass quickly enough and can easily be produced on their own.

Basic methods of installing drywall on a wall surface

To appreciate the advantage of frameless installation of drywall, you can briefly consider both existing methods by comparing them.

To be fair, it should be noted that sometimes when installing drywall it is impossible to do without installing a frame, so this case is also worth mentioning when considering methods for installing the material.

So, there are two main technologies for attaching plasterboard sheets to the wall in order to level it:

1. Installation of sheets using self-tapping screws on a frame made of a metal profile or wooden beam. This method is chosen in cases where the wall requires additional thermal or sound insulation, and the insulating material is installed precisely in frame structure, or if the wall has very large distortions that are difficult to level with plaster layers.
2. Fixing sheets to the wall using self-tapping screws and polyurethane foam or with an adhesive composition made on a gypsum basis. Self-tapping screws and foam for fixing drywall are used if you need to sheathe not only wooden wall, but also surfaces made from other materials that require correction. Adhesive gypsum composition is more often used for leveling concrete or brick wall. However, it should immediately be noted that the frameless method of attaching drywall should only be used when the walls have a height not exceeding 3000 mm.

This publication will consider the nuances of only frameless fastening of drywall.

Required materials and tools

Tool set

To level walls with plasterboard using one of the adhesives, you will need much fewer tools than if a frame was attached to the wall. The list of everything necessary consists of the following items:

1. A plumb line, a building level and a rule, preferably 1500 mm long, to control the evenness of the original wall and the created vertical plane.
2. Electric jigsaw or sharp stationery knife– for cutting drywall.
3. Rulers different lengths, square, tape measure and a simple pencil - for marking.
4. Wide, medium and narrow spatula, as well as possibly a trowel (trowel) - for applying and distributing the solution.
5. Construction float – for processing putty surfaces.
6. Roller and brush - for treating walls with primer.
7. Rubber hammer - for adjusting plasterboard sheets glued to the wall.
8. Electric drill and mixer attachment - for mixing the solution.
9. In some cases it will be necessary for additional fixation with self-tapping screws.

Required materials

Now it is necessary to consider the materials that will be required to prepare the surface of the walls and for high-quality installation drywall:

1. Primer solution with antiseptic additives.
2. Gypsum-based putty mixture, base and finishing.
3. Dry construction mixture - drywall adhesive, or polyurethane foam.
4. Serpyanka mesh tape - for sealing joints between sheets.
5. Long screws may be required to level the wall by adjusting the plasterboard sheets. The size of the fastening elements will depend on the flatness of the surface, taking into account the fact that they must be recessed into the wall by 50÷60 mm.
6. One of the leveling technologies will require pieces of foam rubber - this will be discussed in due course.

About some materials - a little more detail.

Drywall

The Knauf company produces not only a variety of building and finishing mixtures, but also plasterboard sheets for various purposes - this is a simple, moisture-resistant, fire-resistant and moisture-resistant finishing material:

1. Ordinary drywall (GKL or, according to the Knauf proprietary classification - GSP-A) is used for rooms with normal humidity.
2. Moisture resistant sheets(GKLV or GSP-N2) can be used to level walls in bathrooms or bathrooms. After treating such a surface, ceramic tiles will fit perfectly on it.
3. Fire-resistant sheets (GKLO or GSP-DF) are used for finishing walls around fireplaces, stoves, and chimneys.
4. Fire- and moisture-resistant plasterboard (GKLVO or GSP-DFN2) is well suited for finishing walls in boiler rooms of private houses, in attic and attic spaces.

Here we can briefly say about, which does not require special effort, experience and special tools - it is enough to have an ordinary sharp stationery knife on hand. The cutting process takes place in the following order:

1. The sheet is placed on solid foundation- this could be a large table, a floor, or several stools placed side by side at some distance from each other.
2. Then, using a tape measure or ruler, the sheet is marked, and the necessary lines are drawn with a simple pencil.
3. The next step is to draw a knife along the drawn line, also along the ruler, which should cut top layer cardboard
4. The sheet is moved to the edge of a hard surface and laid on it along the cut line.
5. Then, pressure is applied to the edge of the drywall that extends beyond the base, which will cause the sheet to break along the cut line.
6. The last step is cutting the cardboard on the other side of the sheet.

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 the sheathing (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 impact open flame(GKLO). Suitable for rooms with high requirements to fire resistance.
• 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 the load-bearing frame takes up a lot of space and the height of the rooms does not exceed the height of the plasterboard sheet, since with this method the creation of horizontal joints is unacceptable.

To begin with, the surface is cleaned, all uneven areas on the wall are removed, then markings are applied to the wall where the plasterboard panels will be installed. 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 in the corners of the wall from above and below 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. With the second method, on the sheet lengthwise center line cut out a groove and bend it at an angle of 90°. To do this, use a knife with reverse side cut cardboard and gypsum core without damaging front side leaf. 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

For making wooden sheathing, usually take bars 40 mm thick, 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, install horizontal bars. 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 on 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 10-15 mm from the edge of the sheet.

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

The use of plasterboard for wall coverings is beginning to replace traditional materials for surface finishing. And all thanks to a lot of advantages: simplicity, lightness, inexpensive cost of gypsum board sheets, the ability to hide irregularities up to 20 mm. You can carry out the work yourself, without assistance. It is enough to make calculations and choose the appropriate cladding method: with or without a frame.

Features, advantages and disadvantages of using drywall

GKL sheets - universal material, which can be mounted on almost any surface. It has many advantages:

1. 1. The ability to finish walls and ceilings with your own hands as quickly as possible. Due to this, there is no need to use leveling solutions.
2. 2. The structures being built fit perfectly into any design solution- you can create not only flat areas, but also curved and decorative ones (arches, recesses).
3. 3. Drywall has excellent technical characteristics. But due to the fact that it is afraid of moisture, it is impossible to do without the use of waterproofing material.
4. 4. It is very convenient that the entire structure can be quickly dismantled if necessary.
5. 5. When using metal frame you can achieve good rigidity of the base, which will last for a long time.
6. 6. It is possible to lay communications without creating additional “channels”.
7. 7. The surface of plasterboard sheets is treated with any finishing materials.
8. 8. This method of leveling walls is optimal when carrying out internal insulation walls in a wooden house.

Before starting work, it is worth familiarizing yourself with the disadvantages of drywall.

The main disadvantage is low strength. Thus, a gypsum board sheet may burst or crack during transportation, installation, or operation. Therefore, it is important to carry out work as carefully as possible. For the same reason, it is not recommended to use these materials in places where heavy loads are expected. If you plan to hang shelves on the wall for mounting TV, other equipment and heavy structures, it is best to finish with two layers of plasterboard.

Another disadvantage is poor quality sound insulation. To improve this parameter, you cannot do without laying mineral wool or other insulation.

It is worth considering in advance what kind of drywall you will buy. It is divided into the following types:

• simple;
• with increased resistance to fire;
• moisture resistant.

The first type is usually used for finishing rooms with normal humidity levels. Moisture-resistant gypsum board sheets are used in rooms with increased level humidity. GKL with high flame resistance are suitable for kitchens, baths, and other similar premises.

We draw up an estimate - calculating the amount of drywall

To carry out the cladding, all calculations must be made correctly. Here you don’t need to have any special knowledge in mathematics - just calculate the square footage of the room.

Take into account:

• height;
• width;
• length of the room.

It is necessary to measure the room along the entire perimeter, and not just at the corners, since the parameters may vary. This is especially worth remembering for owners of old buildings, where there is often a serious difference in ceiling heights. To take measurements you will need a pencil, tape measure, and a blank sheet of paper.

Instructions for preparing an estimate:

• calculate the area of ​​the walls by multiplying the height by the width;
• from total area subtract the area of ​​windows and doorways;
• We add about 15-20% more material in reserve to the obtained parameters.

How to carry out preparatory activities?

The room needs to be cleared of all objects, all unnecessary items removed from the walls, communications and wiring removed.

Covering with this material covers defects and unevenness, so it is not necessary to level them. But it is worth checking the integrity of the coating. Wallpaper or old paint removed, all existing cracks are sealed.

Wall surfaces must be cleaned of dust and primed.

You will need the following tools:

• gypsum board sheets;
• profiles;
• building level;
• roulette;
• hacksaw;
• self-tapping screws;
• brackets;
• screwdriver

Frame cladding technology - step-by-step instructions

In order to sheathe the walls with the highest quality, to obtain a result that will delight you with a long service life, you must carefully follow the finishing technology using gypsum plasterboard sheets.

Marking and installation of guide profiles

Step back from the walls 2-3 cm, draw a marking line where the guide profile will be installed. If you plan to cover all the walls in the rooms, then the markings should be carried out parallel to them. A guide profile is applied along the intended line and installed on the screws. Vertical guide profiles are mounted on the sides of the walls, screwed with self-tapping screws at the base and ceiling.

Evenness must be checked using building level.

Installation of profiles

To fasten the products, first make markings on the surface: draw strict vertical lines from the ceiling to the floor at a distance of 50-60 cm. Brackets are screwed along the markings at intervals of 0.5 m in height.

After this, they are inserted into the lower and upper guide profiles and screwed using self-tapping screws. Each product must be additionally reinforced with brackets.



Communications and wiring

The next step is to lay wiring and communications inside the room. The main thing is that they do not protrude beyond the guides. For installation you need to use special clamps. At this stage, it is very important to pay attention to sealing all joints and high-quality insulation of wires. This will avoid dismantling gypsum board sheets to correct the situation.

Insulation

Even if you do not want to insulate the walls, a layer of mineral wool or other material is still needed to improve sound insulation. The product is cut into strips so that their width is approximately 3-4 cm greater than the distance between the profiles. The insulation is laid as tightly as possible so that there are no gaps between it.

Wall cladding

Sheathing needs to start from the corner: take the first sheet, attach it to the profile, align it along the edges and screw it onto the screws (there should be at least 30 cm between the fasteners). We install the next sheet of plasterboard next to each other, aligning the joints on the profile, and install it further along the entire perimeter of the room.

There are several important advice. The heads of the screws should not protrude above the sheets, but you should also not deepen them by more than 2 mm. For control, you can use a special bit with a limiter.



Sealing seams

Since gypsum board sheets have slightly rounded edges, small seams are formed when they are joined. To seal them, you need putty, a spatula and a special reinforcing tape. The action is simple:

• knead the mixture;
• cut a piece of serpyanka to the required length;
• apply the mixture to the seam and apply reinforcing tape;
• straighten the material, put a layer of putty on top and distribute it over the surface.

You should not make too thick a layer - it is better to apply several thin layers, and apply the putty after the previous layer has dried. When the material is completely dry, it is sanded.

Joints on external corners need to be covered with corner profiles, secured to a layer of putty.

Finish plating

To remove minor defects that may be on drywall, it should be finished with a layer of finishing putty, which is applied with a large metal spatula. If you plan to paint the walls in the future, you need to apply at least two layers. When the material dries, go over the sheets with sandpaper. The top is finished with clapboard or wallpaper.

According to this step by step instructions Apartment partitions can also be made from plasterboard.

Sheathing using frameless method

At this method plasterboard is glued to the walls on special composition. Moreover, work must be carried out only after all “wet” processes have been completed (laying screed, plaster). This will prevent the sheets from being absorbed excess moisture in the room.

With this method of covering walls with plasterboard, the material is glued directly to the bare surface. If it is as smooth as possible, without damage, the adhesive mixture should be applied along the perimeter of the sheet and 1-2 stripes in the center.

But if the walls are made of brick or stone (in this case there may be serious differences of up to 2 cm), the solution must be applied to the sheet area.

It is better to use compounds such as:

• Perflix glue;
• Fugenfüller putty.

But if the differences on the walls are more than 2 cm, they should be leveled using plasterboard pads. To do this, you need to cut the gypsum board sheet into strips about 10 cm wide, mount them on top of each other to form a flat wall.

Before gluing sheets of drywall, do not forget to clean the surfaces from dust, old finishing material and prime them.
