Tips on how to quickly make any structure from profiles and sheets with your own hands. Methods for working with drywall when erecting walls, partitions, we will talk about this in more detail.

Thanks to today's technologies, it has become easier and faster to work with it. GKL is a plaster of paris, enclosed in a fairly strong cardboard. Many people have a question about how to properly work with drywall.

Drywall is not a modern material, it was used in the Soviet Union and was called "dry plaster". A lot of time has passed since then, and drywall has become an irreplaceable material for the decoration of any room. Thanks to today's technologies, it has become easier and faster to work with it. GKL is a plaster of paris, enclosed in a fairly strong cardboard. There are different types of drywall sheets.

Many people have a question about how to properly work with drywall. Before starting work, you need to prepare everything you need and decide what can be done for this room. Previously, drywall was mounted on a 25x40 wooden beam. But the tree is not so strong, it can accumulate moisture and deform. Now they have been replaced with metal profiles. The profiles are attached to the wall at a distance of 40cm from each other. Sheet size 120cm, respectively, the profile runs in the middle and edges of the drywall.

To work from a power tool, you will need a screwdriver, drill or hammer drill. If the walls are wooden or cinder block, then it is not difficult to fix the profiles. But when attaching to a concrete wall, you will have to drill holes and fix the profile on the dowels, and here you cannot do without a puncher. From a hand tool, you need a hammer, metal scissors, a riveter, a level, a plumb line, a knife and a drywall plane, as well as a laser level. And of course you can't do without self-tapping screws. For fixing drywall sheets, metal screws are better suited. They go deep into the gypsum board and go into the profile, ensuring the reliability of the fastening.

The features of the work consist primarily of the type for which the types of drywall are intended. Namely the alignment of the wall or ceiling. Here it is necessary to observe the horizontal and vertical symmetry of the metal profiles. For this, the laser level is irreplaceable. The derivation of the corners is also a crucial moment. Fortunately, the profiles themselves have angles of 90 degrees, which makes it easier and more correct to remove them. Before fixing the sheets, it is necessary to lay insulation or electrical wiring between the profiles, if, of course, this is required.

It must be remembered that this material is quite fragile and dusty during cutting and processing. Before working with drywall, it is necessary to ensure good ventilation of the room. GKL is cut quite well with an ordinary construction knife. The most important thing is to cut through the cardboard cover, and the gypsum itself is cut by a few millimeters and easily breaks off along the notch line. Cut joint seams are well cleaned with fine sandpaper for a better connection with another sheet. Docking seams must be filled with putty. Immediately, a reinforced film is applied to it and on top of it we apply a thin layer of putty with a spatula. Usually the seam is thin and not noticeable. If the seam turns out to be thick, then you can putty the entire wall with a thin layer. Then try to clean the wall, after complete drying.We must not forget about the screws, they must be covered with putty, otherwise they will rust in the future and appear on the wallpaper from glue or water-based paint. Details about the preparation of drywall for painting.

With minimal skills, they also make drastic changes to the interior of the apartment with their own hands. For this, a popular material is suitable - drywall.

Using it, any surface will become flat, slopes are equipped without unnecessary dirt. The material received recognition for its reasonable cost and availability of processing.

More often, the phrase "repair with plasterboard" means sheathing the walls with sheets of gypsum plasterboard to level it. The popularity of the technology is due to the properties of the gypsum board to efficiently and quickly hide irregularities.

Drywall is a demanded material with a wide range of applications

Do-it-yourself drywall repair

When carrying out repair work, they strive for a flat and smooth surface, which subsequently lends itself to any type of finish. How to level the walls using plasterboard?

Initially, the wall surface is cleaned of old finishing material - wall panels, wallpaper. Dismantle switches, sockets, shelves and other elements. The cleaned walls are treated with a composition that prevents the formation of fungi.

To make the result of the erected ceiling with your own hands of high quality, markings are applied. Then it will be easier to fix the racks. The verticality and perpendicularity of the lines is checked by the level. Horizontal lines are drawn on the plane of the floor and ceiling, which determine the width of the space under the skin.

The lathing is made along the outlined lines. Installation begins with a profile called the starting profile. It is installed along the perimeter of the sheathed surface. Then proceed to the installation of vertically located racks. Brackets are used for their fastening. This sequence provides rigidity to the batten and fixes it securely.

Frame for leveling walls

After completing the installation, the battens proceed to the sheathing stage. It is not recommended to install plasterboard sheets horizontally, as the number of seams increases. And according to the statements of professionals, these seams have a heavy load.

Self-tapping screws are used as a fastening element. Using a special attachment for a screwdriver, they prevent the cardboard from breaking through, as it prevents the deepening and acts as a partition.

Bit nozzle for gypsum board

Alignment finishes work. Butt seams are formed between the gypsum board, which are sealed with a reinforcing mesh. It prevents the formation of cracks in the plaster and prolongs the life of the cladding. After the seams are processed, they begin to putty the surface.

Plasterboard is used not only for walls, with its help they create suspended ceilings - a profile frame sheathed with gypsum sheets. The installation sequence is similar to DIY wall cladding.

Layout is an initial and important stage. A baseline is drawn along the perimeter. When applied, 100 - 150 mm recede from the ceiling. The main markings, along which the profile frame will be erected, is applied to the ceiling itself. The marking step does not exceed 600 mm.

When the marking process is over, the stage of assembling the frame begins. Initially, the starting profile is attached. The work is done slowly and meticulously, the level of profile placement is even.

Plasterboard false ceiling frame

The next stage is the installation of suspensions according to the previously applied markings on the ceiling. These are U-shaped metal plates to which the profile is attached. The edges of the plates are folded back. In this way, the profile frame of the false ceiling is formed.

Plasterboard is attached to the ceiling in a similar way to the previously described process for sheathing the walls of the gypsum board.

The material is used in the decoration of door slopes and window openings, which is used for major repairs or installation of PVC windows. It is better to choose an expensive material - moisture resistant.Its structure is resistant to mold and moisture. DIY slopes are performed according to the following principle:

The dimensions of the window opening are measured. According to measurements, the required gypsum plasterboard strips are cut;
The F-shaped profile is installed on the window frame. For fastening use "liquid nails" or "bugs" (screws).
The formed groove is filled with a sealant;
The empty space is filled with insulation, the thickness of which is chosen taking into account the free space in order to occupy it completely.
With a special glue for working with gypsum plasterboard, the profile and the drywall sheet are held together. In this case, the latter is leveled and tightly pressed against the opening.
All the joints obtained are covered with putty and painted with a helmet. Do-it-yourself slopes are ready.

Plasterboard slopes

Giprok is an affordable, but fragile material. The need for recovery arises from time to time.

When it comes to holes, the amount of work depends on their size. Minor holes (30 mm maximum) are filled with putty, and larger holes are repaired by replacing the damaged fragment. If the diameter of the damage exceeds 10 cm, then installing a new fragment, it is reinforced with plywood strips. This will create an improvised sheathing.

In case of flooding, it is realistic to repair the plasterboard ceiling. The following possible actions are distinguished:

Slight wetness. Turn off the electricity and leave the ceiling to dry.
Average wetness. In places where water comes through (drips), through holes are made. Any object like a screwdriver, knife or metal pin will come in handy for this. After complete drying, the cracks made are sealed with silicone.
If water flows from all the cracks in the ceiling, through holes are made. In the place of greatest flooding, spacers are installed. This will prevent sagging or tearing of the plasterboard sheet. Cut openings on both sides of the ceiling and allow warm air to dry quickly and completely

Plasterboard ceiling after flooding

It is easier to restore the ceiling with your own hands after a long and abundant flooding than to redo it. The following video will help to make sure of this, which describes in detail the installation of the ceiling from the gypsum board.

Frequently encountered problems are cracks. It is easy to close them with your own hands. A crack that has arisen on the inner corner surface is covered with a serpentine, fixing it with a thin layer of putty. With a spatula, the serpyanka is pressed into the surface. A day later, this area is putty.

Cracks at the seam are sealed with a putty mixture. But first, the reinforcing tape is removed from the damaged area. After that, a new composition is applied and the joint is glued with tape.

It is quick and easy to restore or build a floor from gypsum plasterboard with your own hands. The work is not time consuming and affordable.

Despite the fact that drywall was used back in Soviet times, it became widespread only in the last two decades. Working with drywall with your own hands is quite within the power of a simple layman with a minimum of construction skills, and the scope of this material is extremely wide. It is ideal for leveling walls and ceilings in apartments, erecting all kinds of arches, interior partitions and creating other interior details that give the apartment its individuality.

Plasterboard is prized by finishers for its undeniable advantages.

The material has an excellent value for money.
In addition to solving aesthetic problems, it can be used for insulating apartments, increasing their noise insulation.
Under its surface, it is easy to hide not only the unevenness of the wall, but also protruding pipes and communications.
Working with drywall is not accompanied by as much dust and dirt as, for example, plastering walls or whitewashing the ceiling.
This finishing material is environmentally friendly, does not conduct electricity and is easy to use.

All these factors have determined the widespread use of drywall in repair work.

Before you figure out how to work with drywall, you need to decide on its types. The building material must be selected taking into account the specifics of the room and its microclimate. For convenience, the sheets of material are painted in different colors depending on the type.

In ordinary rooms with normal humidity, gray plasterboard is used.

Fire-resistant sheets marked with the abbreviation GKLO are painted in pink or light purple. They are used for finishing surfaces near stoves and fireplaces.

The letters GKLV and green color denote moisture-resistant drywall for bathrooms and kitchens.

To decorate the walls and ceilings in the kitchen, you can also use sheets of dark gray or blue, bearing the designation GKLVO. They combine good moisture resistance with increased fire resistance.
To create curved structures, arched gypsum plasterboard GKLA is often used. It is thinner - 6–7 mm and is very flexible.

The most detailed information about the types of this material and its parameters, as well as about its classification according to the new GOST, can be found in the article "The main characteristics of a drywall sheet".

Installation of drywall can be carried out in two ways: on glue or on a frame. More often, a frame structure is used, which has only one drawback: a more significant reduction in the interior space of the room. But with its help it is easier to level the walls or ceiling, provide heat and sound insulation of the room, hide communications.

Fastening drywall to a frame made of wooden blocks is now rare, it is much more convenient to use special metal profiles. Their length is standard and is 3 m, and the remaining parameters are indicated in the profile marking. The first number is the profile width and the second is its height.

The basis of the frame for drywall is made up of guide profiles with the designation PN or UW. Ceiling or rack-mount profiles are attached to them.
For fastening suspended ceilings and for wall cladding, guides are used that are marked with PNP or UD.
PP or CD ceiling profiles are inserted into the guides, which are also used for leveling walls, which are subsequently fixed with hangers with crabs or anchors. With their help, a frame and lintels are formed.
To create walls and partitions, rack profiles are inserted into the guides, designated by the abbreviation PS or CW.

For curved structures and arches, a special arched profile is used. There is also a corner profile designed to strengthen the outer and inner corners.

In addition, a wide variety of fasteners are produced, thanks to which working with drywall with your own hands on walls and ceilings turns into an assembly of an exciting designer.

The profiles are attached to the wall and ceiling using U-shaped brackets, self-tapping screws and dowel-nails "quick installation". To fasten the profiles together, you can use rivets or a cutter (special assembly pliers). A lot of parts for fasteners are produced, but with a single do-it-yourself work, most of them will not be required.

It is better to prepare the tool that will be needed when installing a drywall structure in advance.

When attaching the profiles to the wall, you will have to drill many holes for the dowels. With a conventional hammer drill, this process can be a pain. Therefore, it is better to stock up on a good puncher.
A screwdriver with a set of replaceable bits is useful when mounting the frame on a wall or ceiling and fixing drywall sheets.
You will also need a hammer, metal scissors, a screwdriver, a level, a plumb line, a stationery knife and a spatula.

This is a necessary minimum; you can expand the list of tools based on your needs and capabilities.

In order to cut a sheet of drywall, you can use a regular stationery knife.With its help, an incision is made along the ruler on one side of the sheet, after which the sheet is easily broken into two parts.

If you want to cut a curved hole, such as an arch, it's best to use a jigsaw. It is necessary to insert a file for metal into it and cut at maximum speed.

In the vast majority of cases, drywall structures have flat surfaces. But the GKL sheet can be easily bent. This can be done dry and wet.

In the dry method, suitable for the tightest bends, transverse cuts are made on the surface of the drywall sheet in increments of 1 to 5 mm. Their depth can be up to 6 mm. The smaller the radius of curvature, the more often you need to make such lines. After giving the sheet the desired shape, the cuts are filled with plaster putty.

To obtain a smooth bend, you can do without cuts. The gypsum board sheet is attached with one side to the prepared curved frame, the free side is slowly and carefully bent, rounded to the shape of the frame. This work is best done together.

Check out this video tutorial that shows how the pros do it:

With the wet method, the side of the GCR sheet, which will be concave, must be moistened. For the best effect, you can walk on the surface with a needle roller, and in its absence - with an ordinary fork. Once wet, the sheet can be gently bent to form the desired shape. It is best to carefully lay it on the template, wrap it with tape and leave it to dry completely.Regardless of the purpose and method of fixing drywall, the surface of the wall or ceiling needs preliminary preparation.

Old coatings are removed. This can be paint, wallpaper, or loose plaster.

Large cracks are primed and sealed with cement mortar.

The surface is treated with an antiseptic, otherwise mold or fungus may develop under the drywall.

In most cases, this method is used to level the walls. The order of installation work will be as follows:

A line of the inner edge of the drywall sheet is drawn on the ceiling. In this case, the distance from the wall cannot be less than the profile thickness, that is, 30 mm.

The guide profile UD is screwed along this line. Its outer border should coincide with our line, and it will be between the wall and the mark.

Using a plumb line, draw the same line on the floor and screw on another UD profile. If everything is done carefully, the profiles will be in a single vertical plane.

Installation of vertical racks is in progress. Each drywall sheet must be screwed to three of these CD profiles: one in the center of the sheet, and two at the edges. With a standard plasterboard width of 120 mm, vertical posts must be installed every 60 mm. The adjacent sheets will also be attached to the profiles located at the edges. The verticality of the profiles is checked using a level.
Racks are fixed with a cutter or self-tapping screws. In order for the frame to acquire rigidity, each post must be connected to the wall by means of brackets. They are fixed to the wall with dowels with a pitch of 500–600 mm. In the future, their edges are bent and attached to the profiles using self-tapping screws. In this case, it is necessary to avoid the curvature of the racks, controlling their verticality by level.

After the frame is ready, insulation is laid in it, if this was provided for by one of the tasks of the construction of the structure, and drywall is screwed on.

If the ceiling is leveled using drywall, then anchors are used instead of dowels when fastening. Rough plastic dowels and self-tapping screws can only be used for light loads. Also, when installing the ceiling, wire strands and "butterflies" are used, which are necessary if the distance between the ceiling and the gypsum board sheet is significant.

Plasterboard sheets are attached to the frame with self-tapping screws 30–35 mm long.The distance between the attachment points should not exceed 20 cm, most often a step of 10-15 cm is chosen.

The caps of the self-tapping screws must be deepened into the sheet by a few millimeters.

When fixing drywall, a gap of 1–2 mm between adjacent sheets is allowed. At the final stage, it is necessary to process these joints so that the plasterboard surface is ready for finishing.

If the sheets do not have a factory chamfer, then you need to make it with a sharp knife at an angle of 45 degrees.
This triangular seam is filled with putty, and a serpyanka mesh is glued on top. It is pressed with a spatula and embedded in a putty. The corners are putty using special corners with perforations. You should also remember to fill with putty all the grooves formed at the points of screwing in the screws, otherwise the rust from them will eventually show through the finish.

After the putty dries, the entire surface of the drywall should be primed.
After the time required for the primer to dry, a finishing layer of putty is applied. Excess can subsequently be removed with fine sandpaper.

The perfect base for a fine finish is ready.

Today, one of the most popular finishing technologies is the renovation of apartments with plasterboard: with your own hands and with the skills to work with this material, you can radically change the appearance of the room in the shortest possible time.

The range of application of gypsum board for apartment renovation is very wide. It can be used to level walls, make a ceiling, equip door and window slopes, and much more. At the same time, the low cost of the material and the simplicity of its processing make gypsum plasterboard very popular. In our article, we will talk about how to make repairs with drywall, as well as technologies for restoring damaged structures from gypsum plasterboard.

GKL - a material with a very wide range of applications

When they mention the repair of an apartment with plasterboard, they most often mean exactly the alignment of the walls with the help of sheathing from gypsum plasterboard sheets. This technology has gained its popularity due to the fact that the use of plasterboard allows you to quickly and efficiently hide almost any irregularities in the wall.

At the same time, the result of the work is a smooth and even surface, ideal for any finish.

Wall leveling frame

How is the alignment of the walls with plasterboard performed?

The technology is quite simple:

First, the wall must be cleaned of old wallpaper or wall panels, and also all shelves, brackets, sockets, switches, etc. must be removed from it.
After that, the surface of the wall is treated with an antifungal compound - it will protect the space under the plasterboard sheathing from the spread of mold.
The next step is to mark the wall for the crate. With the help of a level, we draw vertical lines on the wall, along which we attach the racks to the buoy.
On the floor and on the ceiling, draw horizontal lines that determine the distance from the wall to the sheathing.
Then, according to the markings, we begin to mount the plasterboard crate. First, we attach the starting profile around the perimeter of the room, and then we install vertical racks on the brackets (see the video attached to the articles of this section of the site).
By connecting the post profiles with the starting ones, we securely fix the crate and give it the necessary rigidity.

When the lathing is ready, you can start sheathing.

Advice!
Our impromptu renovation school strongly recommends installing plasterboards vertically.
This is due to the fact that the main load falls on the horizontal seams between the sheets of gypsum board, which means that you need to place the material in such a way that these seams are as small as possible.

We fasten the plasterboard boards cut to the size of the room to the crate with self-tapping screws.
So that when fastening the screws do not break through the cardboard, you can use a special nozzle on the screwdriver bit (pictured).
It acts as a limiter and does not allow the self-tapping screw to go deep into the plate.

The final stage of wall repair using gypsum boards is leveling for finishing. We glue the seams between the sheets of drywall with a polymer reinforcing mesh, after which we process the seams and the entire surface of the wall with putty.

In addition to leveling the walls of drywall, you can make a suspended ceiling. Such a ceiling is a structure made of gypsum plasterboard sheets, fixed on a metal frame for drywall.

The instructions for making a suspended plasterboard ceiling with your own hands are quite simple:

We start with the layout of the premises. First, along the perimeter of the entire room, stepping back from the ceiling 100-150 mm, draw a base line using a level.
Then, on the ceiling itself, we apply markings with a step of 600 mm - along which we will fix the main ceiling profiles.
After marking, we proceed to assembling the frame. Along the baseline, we fix the starting ceiling profile for drywall, making sure that all the panels are placed at the same level.
Then we fix suspensions made of metal U-shaped plates to the ceiling according to the applied markings.
Bending the edges of the suspensions downwards, we fix the main profiles on them, thereby forming the plane of our ceiling. We put the edges of the main profiles into the starting groove and fix them with a self-tapping screw or special pliers for galvanized metal.
We cover the finished ceiling frame with plasterboard and level it with putty using the same technology as the walls.

Plasterboard ceiling

Another use for drywall that can be found in an apartment during renovation is for finishing window slopes.

Note!
The restoration of slopes may be required both during major repairs and after replacing old wooden windows with metal-plastic ones.
In this case, an inexpensive and easy-to-handle drywall is almost irreplaceable!

Window slopes from gypsum plasterboard are made as follows:

Fastening the starter profile to the frame

We measure the window opening with the installed window. According to the dimensions obtained, we cut out the necessary panels from the gypsum board.
We fix the starting F-shaped profile on the window frame with the help of glue "liquid nails" or self-tapping screws - "bugs". This profile is designed for plastic panels, but it is also great for gypsum plasterboard.
Fill the profile groove with acrylic sealant.
We apply mineral wool insulation to the wall. The size of the insulation is selected so that it occupies the entire space between the wall and the slope.
Apply glue for gypsum boards to the profile panel, after which we insert one edge of the panel into the groove of the starting profile. We press the drywall to the window opening, while leveling it.
After installing all parts of the slope, we process the joints with putty and paint the slope with interior paint.

Advice!
For slopes, it is better to use moisture-resistant drywall, since it is more resistant to getting wet, as well as mold.

The popularity of drywall as a finishing material leads to the fact that more and more gypsum plasterboard structures appear in our houses and apartments. And these structures, along with all others, periodically require repair - especially since the gypsum is not very durable.

Below we will tell you how to repair drywall with the most common damage:

If a small (up to 25-30 mm in diameter) hole is punched in the plasterboard wall, then it can simply be covered with putty.
To do this, first we remove all damaged areas of the gypsum board, after which we fill the hole with a plaster-based putty with a wide spatula. After the filler has dried and sanded, paint can be applied to the damaged area.
If the hole has significant dimensions, then the repair of the plasterboard wall is carried out with the replacement of a fragment. To do this, cut out the damaged area, and in its place we glue a piece of plasterboard of the same shape.Further, as in the first case, putty and surface cleaning are performed.
When sealing holes larger than 10 cm, before inserting a new fragment from the seamy side of the gypsum board, you can attach several plywood strips with self-tapping screws.
These strips will play the role of an improvised lathing and will not allow the damage to expand when the skin is deformed.

Replaced fragment putty

Cracks are a separate category of damage to drywall structures.

You can also deal with them in several ways:

If a crack appeared on the inner corner, then first we apply a thin layer of putty to the corner itself, after which we apply a serpentine tape. Using a putty knife to seal the corners, press the serpyanka into the filler, removing excess material. After 24 hours, the treated area can be putty and painted.
We also seal the crack at the junction with a putty mixture. To do this, first remove the damaged reinforcing tape, then apply a gypsum composition, and then glue the joint again with tape.

As you can see, repairing walls with plasterboard, as well as restoring structures from gypsum plasterboard, can be done quite simply and quickly. At the same time, the low labor intensity of the repair process and the relatively affordable cost of finishing materials allow you to take on such repairs yourself, without involving outside people!Drywall is one of the most environmentally friendly materials. The material is inherently unique. Indeed, with its help, you can realize any ideas, even the most unrealistic, with your own hands, and also perform easy and high-quality repairs - drywall is simply irreplaceable.

Gypsum crate production scheme.

Plasterboard is used for the manufacture of structures for various ceiling and wall decorative elements, for the construction of partitions, the creation of a multi-tiered ceiling and the device of unique illumination of apartments and houses.

It is also suitable for the manufacture of arches, boxes, partitions, furniture used as decorative elements of apartments. Using drywall when you need a quick and stylish apartment renovation is ideal.

Its installation and operation does not require much effort and maintenance. This material has fire resistance properties, non-toxic, unlike various plastic counterparts. Do-it-yourself renovation of your apartment using drywall will delight you with its speed and simple installation.

As for the advantages of drywall, they include its ability to maintain a normal apartment microclimate. Since its structure is porous, it easily absorbs excess moisture, and in dry air it releases the accumulated liquid back. In a room decorated with plasterboard, it is easier to breathe, which undoubtedly has a beneficial effect on human health.

Of course, if you have never encountered drywall before, it will be difficult for you to repair a GKL apartment with your own hands. But this is fixable. Since there is nothing complicated in the technology of working with drywall. After reading several useful articles on how to install various drywall structures, you can easily master this option for apartment renovation.

A tool for working with drywall.

In order to carry out apartment renovation using drywall with your own hands, you need to be puzzled by the availability of the following necessary materials and tools. These include:

drywall sheets;
metal profile (for making the frame);
screwdriver;
screwdriver and hammer;
building level (preferably laser version);
dye cord;
angle (90 degrees);
special knife for drywall;
hacksaw;
electric jigsaw;
cross-shaped connectors for a profile, the so-called crabs;
staples designed to secure the profile to the base of the wall or ceiling;
mineral wool for heat and sound insulation;
pencil;
brush and roller;
putty knife;
dowels and screws;
primer;
reinforcing tape;
putty (for sealing joints);
depending on the subsequent finishing of the apartments, either paint, or wallpaper, or tiles.

It is most convenient to install the gypsum board together or using a special device - a lift. By weight, drywall is quite light, but its dimensions are not very convenient in order to work alone. The width of the drywall is 1.2 m, but the length can be either 2.5 m or 3 m.The lift will be indispensable if you are doing ceiling sheathing alone, and this device will not be superfluous for wall sheathing.In order not to spend money on unnecessary building materials, it is necessary to calculate the required amount of drywall, profile and other necessary materials. This will not be difficult if you know the area of the surface to be covered with plasterboard. If not, you need to make measurements.As for the required number of drywall sheets, everything is quite simple. We calculate the area of one plasterboard sheet. To do this, multiply the width of the sheet by its length. In a similar way, we calculate the surface area to be clad. And then we divide the resulting value of the surface area by the area of the drywall sheet - the number of sheets required is obtained.With a wall height of more than 2.5 m, you need to purchase a gypsum board with a length of 3 m.This will help you to reduce the number of horizontal seams. And fewer seams increase the strength of the drywall structure. It is better to purchase drywall with a small margin, about 15% more than the calculated value.One more tip! For ceilings, it is better to use drywall (ceiling) with a thickness of 9.5 mm, although the use of wall (thickness - 12.5 mm) is also not excluded. For the manufacture of niches intended for a small load, you can use ceiling plasterboard, for arches - wall, ceiling or special arched (the thickness of which is 6.5 mm). Image - DIY drywall repair

Diagram of the center distance of load-bearing and main profiles for drywall.

To calculate the amount of the required profile, you need to decide on the step of its installation. The rack vertical profile is installed in 60 cm increments, but there are also such designs in which the step is 40 cm.

The length of the perimeter profile will match the length of the wall perimeter. In order to make a plasterboard partition, a special type of profile is used, its width can be 5, or 7.5, or 10 cm. Such a profile is mounted in 60 cm increments.

Let's move on to calculating the number of staples. Using brackets, the profile is fixed in one plane with another profile. The brackets are mounted to the ceiling or wall using dowels or self-tapping screws at a distance of at least 50 cm. The bracket is fixed to the profile with self-tapping screws for metal (9.5 mm).

Modern apartment renovation without the use of drywall in our time is quite difficult to imagine. Old uneven walls of an apartment are easily transformed if you use gypsum board for cladding them.

Installing drywall on the wall.

The cost of such apartment renovation is low, the installation is quite easy and can be done independently. Another plus! Using drywall, repairs will not give you the hassle of getting rid of a large amount of construction waste.

The sheets are fastened to a metal frame made of a profile, which is fixed along the entire perimeter to the floor, to the ceiling, and to the wall. If your walls are flat enough, you can simply glue the drywall onto the surface to be repaired using a special adhesive.

After facing with plasterboard, your walls will acquire a unique flat surface that does not require additional leveling work.

Plasterboard sheets must be installed in an upright position. The edges of the sheets should be flat, not damaged and should fit tightly to each other during installation.

For fastening to a metal frame, self-tapping screws for metal (2.5 mm) are used, located approximately every 25 cm.

When decorating walls with plasterboard, you can additionally soundproof them. Various materials are used for this. Soundproofing is placed between parts of the frame, preventing it from protruding beyond the edges of the profile. This is necessary so that the soundproofing material does not interfere with the fastening of the wall to the frame.Performing installation work with drywall with your own hands, you save money. Since the execution of such work to order is not a cheap pleasure. And finishing drywall, for example, putty or applying a decorative type of plaster, as well as many others, will cost even more than installation.

Of course, the price will be influenced by the amount of work and the complexity of the design, the type of finishing materials and much more. But by doing repairs using drywall with your own hands, you will save not only money, but also reduce time and labor costs.
