To date, drywall is rightfully recognized as one of the most popular and sought-after materials. This is due to its affordability and undeniable ease of use. He is often used to level the floors in the house. Today we will talk about how you can attach drywall to walls, and also get acquainted with all the pros and cons of this common finishing material.
Before embarking on the study of such a finishing material as drywall, it is worth understanding what it is.
Drywall is a finishing material that consists of two layers of cardboard with hard gypsum and special fillers inside. It is used for a wide variety of purposes. Sheets with different thicknesses are produced for different jobs. Plasterboard panels can be laid not only on walls, but also on the floor or ceiling. The main thing is to choose materials of a suitable category.
Today in the stores of building and finishing materials you can find absolutely any product for any repair work. To level the walls, customers are offered high-quality putties, plasters and other practical compounds. However, many people choose “dry” material for such work - drywall.
To date, the problem of uneven walls is familiar to many. It is faced by both owners of private houses and city apartments. However, it is quite possible to make the floors even on your own, without involving a team of finishers.
Uneven floors are bad not only because they look unpresentable, but also because many finishing materials cannot be applied to them. These include tiles, most types of paints and wallpapers. On a base with drops and potholes, such coatings do not hold securely, and they look very sloppy. Many of the finishing materials even emphasize the bumps on the walls.
In such cases, you can not do without a perfectly even and smooth drywall. After its installation, the walls acquire a more aesthetic and neat appearance. In addition, the sheets of this popular material are as simple as possible to process and can be covered with almost any canvas and paint.
Plasterboard sheets are attached to the wall using a special wooden or metal frame. There is also a frameless installation method, which experts consider more difficult.
When choosing one or another installation method, it is worth considering that you need to work with drywall carefully. This is due to its peculiarity, which consists in fragility and the possibility of crumbling. If you accidentally damage the drywall, then it is unlikely that it will be possible to restore its original appearance. That is why ordinary drywall is not suitable for the manufacture of, for example, arched structures, since it will simply break with slight bending.
Another distinctive quality of drywall is its multitasking. It is used not only to level different bases, but also to make interesting multi-level ceilings, shelving with shelves, niches and cabinets. This once again confirms the unpretentiousness of this material and the ease of working with it.
Like any other finishing material, drywall has advantages and disadvantages that you should be aware of if you decide to install it on the walls in your home.
First, let's get acquainted with the list of positive qualities of drywall sheets:
As you can see, the list of positive qualities of drywall is quite impressive.
However, it also has its weaknesses:
How significant are the listed disadvantages - each consumer must decide for himself. But it is worth noting that many problems can be avoided if you choose the right material and strictly follow the instructions when attaching it to the walls.
If you decide to independently install drywall on partitions in your home, then you should stock up on tools and materials.
From the toolkit you will need:
From the materials you will need:
Drywall is a versatile material. It is used in a variety of conditions and seamlessly fixed on various grounds.
You simply cannot do without this material when it comes to a wooden house or a log house. In such conditions, the walls are almost always uneven and require proper alignment. However, it should be borne in mind that wooden houses always shrink and gypsum boards can only be installed in them after this process is completed. Otherwise, the sheets may be damaged under such conditions or deformed.
To install drywall on walls in wooden houses, you must:
Aligning the walls in wooden houses is not an easy task. In this case, the best option would be frame mounting. However, some owners first attach sheets of plywood or chipboard to the boards and bars, and then drywall is glued to them.
Drywall can also be attached to walls with a concrete base. For such surfaces, it is not at all necessary to make a complex frame. Drywall can be glued to such bases using special glue. Such adhesives are very common in stores today. For example, the well-known company Knauf offers a high-quality Perlfix composition.
Drywall is often used to level brick walls. Here you can also refer to the usual gluing of the material without making the frame. In such cases, immediately before installation, it is necessary to find out with the help of a level how curved the floors are, after which any dirt, dust and grease spots are removed from the brick. In addition, the brick wall must be absolutely dry, otherwise it will not be possible to achieve sufficient adhesion with drywall even when using high-quality glue.
In case you want to align the walls of foam blocks, then you should turn to the frame installation method. This is due to the softness of such grounds. However, some users turn to frameless installation, but before that, the foam block must be prepared - finished with soil or plaster.
Aerated concrete walls also often require alignment. In such cases, both frame and frameless mounting methods can be used. In the second case, it is necessary to treat aerated concrete bases with a deep penetration primer. Glue in such cases must be selected especially carefully, as in cases with foam block ceilings. Experts recommend using compositions from Knauf and Volma Montazh.
Drywall can make the walls smooth even in adobe houses. Such buildings are full-fledged composites built from clay, earth, straw and sand. Of course, with such building materials, there is no need to talk about perfectly even partitions. For this reason, they simply need leveling sheets such as drywall.
We have already mentioned above that drywall sheets are attached to the walls by making a frame or in a frameless way. The choice of one or another installation option largely depends on the structure and conditions of the room and, of course, the preferences of the owners.
This option for installing drywall is the most popular. It is quite possible to make it yourself. With this method, gypsum sheets are installed on a pre-prepared frame, consisting of metal profiles fixed along the wall.
It is worth considering some of the nuances of this common installation method:
Mounting drywall sheets on the frame has several advantages:
Let's take a closer look at the step-by-step instructions for installing drywall on the frame:
According to experts, this installation technology is simpler. However, it should be borne in mind that such a design will take up part of the area in the room, so in a very small room it is better to use the frameless method, unless, of course, this is allowed to be done.
The frameless fastening of drywall is also called adhesive, since with it the sheets are fixed on the ceilings with the help of a special adhesive.
When choosing this installation option, you must comply with the following conditions:
Frameless drywall fasteners can only be accessed if the curvature of the walls does not exceed 4 cm. Otherwise, it is better to build a profile frame.
Glue plasterboard on the base can be in different ways.
The best option must be selected based on the technical condition of the floors:
Now it is worth considering in more detail the instructions for the profileless installation of drywall sheets:
Drywall is a lifeline in matters of wall alignment. Installation of gypsum sheets cannot be called unbearably difficult and energy-intensive.
To get a more aesthetic and reliable design, Consider the following advice and recommendations from professionals:
Drywall is one of the most popular building materials. It is used for leveling surfaces, building partitions during redevelopment, installation of various structures. It is not difficult to work with the material, even a novice home master can do it. Installation must begin with the construction of a wooden or metal frame. Despite the fact that the metal base is more durable and easier to install, many prefer a wooden frame for drywall.
The use of a frame makes it possible to hide the flaws of any surfaces without compromising the useful area of \u200b\u200bthe room. Its construction must be taken seriously. The success of further work depends on how accurately it will be calculated and designed.
For the construction of the frame, you need to prepare wooden bars. It should be coniferous wood, the best option is pine.
The material must be flawless and well dried so that during operation it does not deform and withstand heavy loads.
Before starting to work with the material, it should be treated with an antiseptic composition. The antiseptic should not be toxic, since the work will be carried out indoors. It should easily penetrate into the wood, not decompose, not wash out and not have a smell. Do not use oily antiseptics. This can adversely affect the health of the residents of the house.
The thickness of the bars must be at least 40 mm. Permissible humidity - no more than 15-18%. However, the thickness directly depends on the dimensions of the future GKL structure. For example, when constructing a partition, attention should be paid to its width and height. The larger these values, the larger the cross section of the bar should be. For wall or ceiling cladding, the width of the material is selected based on how much usable area I would like to save. If the surfaces are very uneven, you should use bars of different sections.
Figure 1. Rigid fastening of a wooden frame to the wall.
To fix a wooden frame to walls or ceilings, there are two ways. One of the most reliable is considered to be a rigid mount directly to the wall (Fig. 1). The binding is done first. If the frame is built on the ceiling, then the bars are attached to the walls. If a wooden frame is made for a wall, then the fastening of the bars is carried out to the ceiling, floor and walls located perpendicularly.
The plasterboard frame can be attached to ceilings or walls in another way: using metal brackets. The advantage of this method will be quick installation, and the disadvantage is the low rigidity of the structure.
Before making a wooden frame, for example, on a wooden ceiling, it is necessary to mark up (Fig. 2). For this, the lowest point of the ceiling is determined. From it you need to retreat 50 mm and draw a horizontal line around the entire perimeter of the room. A strapping rail will be fixed along this contour. To draw an accurate horizontal line at the corners of the room, marks are made at the required level. A cord is pulled between them and a straight line is beaten off. In the rail, you need to drill holes for fasteners with a diameter slightly larger than that of a self-tapping screw or screw.
Figure 2. Marking the frame: 1 - prepare a pencil, an angular ruler and a level, 2 - using a level and a pencil, you should make an even marking for fastening the profiles, 3 - the profile is applied to the marking and screwed to the floor and wall, 4 - marking the attachment point with using a plumb line, 5 - assembling the frame and checking the evenness with a level.
The rail is applied to the line on the wall and the marks of future fasteners are transferred to the surface with a pencil. Then holes are drilled into which dowels or wooden plugs for self-tapping screws will be hammered. Reiki are fixed around the perimeter.
The next step is to install the base of the bars on the surface of the ceiling. The fastening step of the parallel bars should not exceed 800 mm. This will ensure the reliability of the future design. Supporting bars are attached perpendicularly, on which drywall will subsequently be mounted.
The frame for the wall can be assembled on the floor and only then fixed to the wall. The size of the wall on which the drywall will be attached is measured. From the result, subtract 5 mm on each side and cut out the bars of the appropriate size. Assemble the frame from 2 horizontal and 2 vertical bars. Additional rails are fastened with a step of 600 mm, crossbars are fixed perpendicular to them. The frame is fixed with dowels, screws or dowel-nails around the entire perimeter of the wall. With this manufacturing method, the heat-insulating layer is attached directly to the wall, and the frame closes it.
In the manufacture of the frame, you can do without transverse bars if its length does not exceed the length of the plasterboard and there are no door or window openings on the wall.
Before building a frame for drywall, it is necessary to draw up a drawing of the future partition, on which to indicate the location of the doorway. When calculating the rigidity of the structure, the number of horizontal parts should be taken into account.
To complete the work you will need:
Installation of the frame begins with fixing the strapping bars to the floor, walls and ceiling (Fig. 3). For this, self-tapping screws and dowels are used, if the floors are concrete, and nails, if the floors are wooden. Anchors will be needed for ceiling mounting.
First, the fastening takes place on the ceiling. The boundaries of the future partition are marked, only after that the bars are mounted. With the help of a plumb line, a line is marked on the floor. For more accurate marking on the walls, you need to make several marks. After marking is completed, the beam is fixed on the floor.
Figure 3. Installation of the frame begins with fixing the strapping bars to the walls, floor and ceiling.
The next step is to attach the vertical strapping that will connect the ceiling and floor bars. Vertical racks will carry the main load in the structure, so the fastening should be as strong as possible with a fastening pitch of no more than 400 mm. If the main walls in the room are not made of durable materials, then dowel-nails are used for fastening. You can drill holes in the wall in which to place plugs from wooden pegs and screw in screws or hammer in nails.
If the main walls are strong and smooth, then the strapping can be fixed on straight hangers, which are used for a metal frame.
When the strapping is ready, racks are installed with a pitch of 600 mm. It is this step that will make it possible to mount each standard sheet of plasterboard on two racks. Racks can be fixed with metal corners.
For horizontal lintels, a beam with the same cross section is used as for the entire structure. They are fastened with screws. For greater reliability, metal corners can be used.
The opening for the door in the new partition needs reinforcement. For this, additional racks and horizontal jumpers are used. The threshold will be the lower part of the frame.
Laying communications in such a partition is not recommended. However, if necessary, holes of the required diameter are drilled in the racks. The electric cable is laid in special protective corrugated pipes or tin boxes.
Such a popular finishing material as GKL, in most cases, is attached to a special frame. Usually it is mounted from metal profiles. An alternative option is a crate made of wooden beams, which is very easy to assemble with your own hands. But do not be deceived by the ease of manufacture: wood is a capricious material, its use is far from always possible. Consider all the features of this design and find out when and how you can make a wooden crate for drywall on your own.
The construction of a wooden frame under the gypsum board attracts with its low cost and ease of operation. Especially if during the repair a small number of boards remain, which can be used as slats for the supporting structure. In this case, you do not have to spend money on the purchase of a metal profile, as well as the necessary fasteners, for example.
But you should also remember about the properties of wood that limit its use in construction:
It is recommended to use a wooden structure for plasterboard sheets:
Advantages of a wooden crate:
First of all, you will need a wooden beam itself with a cross section of at least 40 × 40 mm. If it is planned to carry out insulation and soundproofing, then the beam must be chosen thicker, for example 40 × 80 mm. To prevent decay, it is impregnated with antiseptic and water-repellent solutions. It would be useful to treat it with a composition that improves the fire safety of the material.
Before installation, all wooden elements must be kept indoors for several days in order to adapt to its microclimate and take on their final geometric shape.
You will also need:
As you can see, almost the entire tool can be found in the arsenal of even a novice master. To install a wooden frame and fasten drywall, you do not have to purchase specialized expensive fixtures.
Preparatory work consists in removing the old coating if there is doubt about its strength. Things in the room can be covered with plastic wrap or other material.
The order of the wooden frame device:
In the case of a perfectly even overlap, horizontal bars can be attached directly to the wall. Here, the same thickness of all elements of the crate is of paramount importance: any error in size will result in frame irregularities.
In houses with wooden walls, you can mount racks to the base with wood screws. But you still need to drill holes: this eliminates the likelihood that the beam will crack.
- The heads of the self-tapping screws are recessed deep into the sheet by 1 mm.
- In the future, as well as deepening the heads of the screws.
- After grinding, the surface is primed and ready for further finishing.
Drywall today takes pride of place and is very popular in construction and repair work. Often, partitions are built to redevelop an apartment, and drywall is simply irreplaceable here. The list of advantages is significant: GKL are quite light, the construction speed is high, and the cost is relatively inexpensive. Very often, drywall is installed on a wooden frame.
Pine species are often used as the material for the manufacture of a wooden frame for the construction of a plasterboard structure. Such structures can be used as a room partition. What features does a plasterboard partition on a wooden frame have?
The starting stage in the construction of the structure is the installation of the strapping. The bars are fastened in the following order: ceiling-half-wall. If there are wooden floors in the room, then it is easy to fix the bars with simple nails. For 6 cm slats, 10 cm nails are recommended. If the walls are made of materials such as concrete or brick, plus a layer of plaster, then it will be a little more difficult to fix. In this case, fastening is carried out with anchors to the ceiling and dowels to the wall and floor.
Fastening is recommended to start from the ceiling, having previously marked the place of the future partition. Once the bars are fixed on the ceiling, you can mark the floor and continue mounting. It is important to make the markup correctly, you can use a level or a laser level.
When marking, you need to make at least 3 marks on the floor: one on each wall and one in the middle, you can do more, they will not be superfluous, especially since they will not be visible. After the floor beam is fixed, you need to check its position relative to the ceiling.
After you are convinced of the accuracy of the fasteners, you can proceed to fastening the timber to the wall. Everything is much easier here: connect the ceiling with the floor vertical strapping bars. Subsequently, it is on the vertical racks that the main load will fall, so it is extremely important to fix it well. It is equally important to observe the distance between the vertical bars - no more than 40 cm.
Before you begin to strengthen the structure, you need to assess how strong the walls are.
If you are dealing with walls made of fragile materials (cellular concrete, drywall, and so on), dowels of the largest size are needed. It is allowed to use both dowel nails and special dowels. A variant of the following fastening is possible: drill holes in the wall, drive wooden plugs into them, into which you can subsequently screw screws or hammer nails.
Another way to attach the strapping: take straight hangers (usually these are used when installing a metal frame) and fasten the bars with them. This option is perfect if the walls are quite strong.
Once the harness is installed, you can proceed to the installation of racks. Typically, the distance between the racks is 60 cm, which is very convenient - subsequently, the GKL of standard width (120 cm) can be fixed on 2 racks, which facilitates the installation of drywall.
The racks are installed using wooden bars, screwed to the rack and strapping with screws. You can mount racks and metal corners.
If the partition has a doorway, then you need to add the number of racks, as well as jumpers horizontally. If it is possible to do without communications in the partition, then this is excellent. If you still need electrical wiring, then the wires should be placed in a protective tube or use a tin box.
Sometimes you can’t do without additional insulation in a building, especially if the partition is not decorative. Installation of insulating materials is carried out when plasterboard sheathing is made on one side of the wooden frame. Mineral wool and foam materials are considered the optimal insulation material.
Insulation is quite easy to perform, since the dimensions of the distance between the racks and materials are the same. It remains only to lay the material and fix it. If a rigid material is chosen as insulation, then its fastening must be carried out on the inside of an already lined partition. If cavities are formed during installation, they can be filled with mineral wool. The combination of materials will give a high soundproofing effect.
Often, in the process of facing the second side with plates, a problem arises on the racks in the form of cracks. This is due to the large number of screws. It is easy to avoid such a mistake if the joints of the plates on the walls are made from opposite sides (for example, the 1st side is sheathed on the left, the 2nd on the right).
It is important to remember that a small gap of 1-2 cm must be left between the ceiling and the top of the drywall. The need is that the gypsum in the slab may begin to crumble. The gap will not be noticeable, it is easily closed with a simple plinth.
There are also extended partitions when the installation of drywall is carried out on a double wooden frame. The advantage of this type of construction is that it is possible to lay communications and even install heating radiators.
The differences in the construction of an extended partition are that the strapping will need to be done from 2 sides, leaving the distance that is necessary for communications. A wooden frame is built according to the same principles as a simple partition. As soon as the sheathing is completed on one side, the necessary communications can be laid. The wires must be in a pipe or box.
If there is a need to install a battery, then it should not be installed in the middle of the structure, but closer to one of the sides. Do not forget about the ventilation holes, then they need to be closed with plastic bars. It must be remembered that if you install a battery, then it is impossible to insulate the partition with foam rubber or foam. Mineral wool will perfectly cope with the task. After laying communications, the installation process looks similar to a simple partition.
Not always the room can differ in perfectly smooth walls. The installation of the frame in this case looks a little different. It’s worth starting with identifying irregularities: the beam is placed on the floor along the wall and a line is drawn along its outer edge. Next comes the markings for future racks at a distance of 60 cm. The next step: the rack bar must be pressed against the wall vertically and at regular intervals mark the position of the butt behind its exit on the floor.
It is important to place the support beam evenly, because vertical bars will be attached to it further. To align the racks, you can take scraps of fiberboard, wood or plywood.
You can do the installation of drywall with your own hands, having an idea of \u200b\u200bwhat should happen. It is important to follow a certain algorithm of actions, there is no need to rush here, because it will not be so easy to correct mistakes later. Before the process, you need to make all the necessary measurements and calculations, stock up on the entire set of material and tools that you need. For example:
But the most basic, perhaps, moment in the construction of a plasterboard partition is the documentation for permission. It is not recommended to start work before you have received all the necessary permits.
This article provides instructions on how to attach drywall to wood battens and make installing drywall to wood framing quick and easy.
Cladding of walls and ceilings of internal premises is a fast, inexpensive and fairly labor-intensive modern method of finishing the interiors of civil and public buildings.
There are several options for plasterboard sheathing (GKL):
As a frame structure, both profiles made of galvanized metal sheet and wooden elements - a rail, a bar, a board can serve. A possible frame for drywall made of wood may be preferable to a metal profile, since installing drywall with your own hands on a wooden frame is not particularly difficult and does not require special skills. Wood is easy to process - drilled, sawn.
Is it possible to mount drywall on a wooden frame? Yes, and besides, this allows you to save on finishing, refusing to purchase quite expensive metal profiles. However, a drywall frame made of wood is not recommended when the room has high humidity - in bathrooms, boiler rooms, showers and bathrooms.

How to make a wooden frame for drywall? If a partition is sheathed, it is usually a three-layer structure made of edged boards with a thickness of 25-30 mm. The outer layers are formed from vertical boards, and the inner layer from horizontal ones. If the installation of the partition is done neatly and competently, without distortions, then such a partition actually forms a frame for plasterboard from boards, to which, without any preparation, using self-tapping screws, you can fasten panels from plasterboard.
The use of a board for the manufacture of frame structures in other cases is impractical, as this will lead to an overrun of the material and an increase in the cost and labor intensity of the work. For facing concrete, brick, logs, as well as old warped walls and ceilings, it is better to use a frame made of timber for drywall.
Many are interested in whether drywall can be mounted on wooden slats? Since the difference between wood products (such as a bar and a rail) in relation to the installation of drywall is insignificant, the installation of drywall on wooden slats and the installation of drywall on bars practically do not differ from each other.
Can drywall be fixed to wooden blocks if they are simply fixed to the walls or ceiling? This option is possible, but it is better to make a frame for drywall from wooden blocks. In how to fix the beam to drywall, a small instruction for installing drywall on a wooden frame from a beam will help.
For drywall, panels with the following dimensions are most widely used: 1200 mm wide and 2500 mm long. At the same time, the installation of panels on a frame structure made of wood of different types and characteristics (moisture resistant, hardened, etc.) has the same scope of work.
To determine the required number of GKL slabs, it is necessary to draw a sketch plan for the development of walls and ceilings with all door and window openings, slopes and technological niches (for example, for heating radiators). After calculating the working area, its value should be divided by the area that one GKL has. The resulting value will need to be increased by 20% (for trimming and contingencies), which will be the number of panels required.
It is necessary to put on the plan vertical and horizontal axes, along which frame elements will be installed on the wall, ensuring the fastening of drywall to wooden blocks. Its design scheme will be:
Additionally, bars of the second type should be used to frame window and door openings and technological niches. If the height of the room exceeds 2500 mm, the upper horizontal beam is replaced with a beam with a section of 80 x 40 mm and is installed so that an additional 40 mm serves to fasten the top panel from a GKL sheet cut to the appropriate length, the length of the vertical beams of the first and second should also be increased type and the top beam of the second type is installed.
After calculating the total length of the required number of beams and also increasing it by 20%, they can be purchased at the construction market or made in a woodworking workshop. It is especially necessary to pay attention to the absence of oblique and increased branchiness in them.
Before using for at least one week, the entire set of wooden beams must be aged in the room in which it will be used. After that, a rejection should be carried out, and the rest should be treated with special compounds - antiseptics that prevent decay and damage by fungi and mold, flame retardants that give fire retardant properties. Currently, deep penetration impregnations are commercially available that provide protection for wood and prevent warping during fluctuations in humidity in a room within a fairly wide range.
In the manufacture and installation of the frame, it is necessary to follow the drawn plan.
Tools and equipment that will be required to complete the work:
The assembly of the frame and its installation from individual prepared elements with your own hands directly on the ceiling or on the wall presents some difficulties - constant alignment and adjustment in horizontal and vertical planes is required with the constant use of a plumb line, level, building square and rail-rule.
If the length and width of the room allow, an enlarged assembly of large fragments of the frame can be done directly on the floor. At the same time, it will be much easier to mount the frame, both on the wall and on the ceiling, and align and attach, respectively, in the vertical and horizontal planes.

The horizontal and vertical elements are well connected to each other using pieces of tin metal strip of the desired width (25 mm) bent at a right angle or through small blocks. Both those and others are fixed in the necessary places with the help of screws.
The installation of frame fragments on the walls and ceiling can be done using wood screws, if the walls and ceiling are wooden, using the so-called “plugs”, when a hole is drilled in a brick or stone in the right place, at a predetermined point in the wall, into which a wooden chopstick, into which, in turn, a nail is driven through the frame element or a screw is screwed in, while instead of a chopik, you can use a plastic dowel with a metal self-tapping screw.
After installing and leveling the frame, with significant tuberosity and distortions between it and the wall (or ceiling), gaps may form, which should be filled with gypsum mortar (if the tree was previously protected with moisture-proof impregnation), use mounting foam or wooden wedges and linings together with glue glue for wood, such as PVA. Otherwise, the wooden frame for plasterboard on the wall (or ceiling) will have increased fragility and may be deformed when the GKL panels are installed.
After installation and alignment on the wall or on the ceiling of the frame structure, you can begin to fasten the drywall to the wooden frame by directly mounting the GKL panels. In how to fix the bars to drywall, the following instructions will help.
To mount a plasterboard sheet, it must be pressed tightly against the mounted wooden frame structure, so that the long edges of the sheet lie exactly along the axes of the first type beam with a section of 80 x 25 mm at a distance of 40 mm, and so that it is possible to fix to the remaining 40 mm adjacent sheet.
Fastening is carried out using self-tapping screws with a length of 20 mm. Using a screwdriver, you need to start fixing the GKL sheet on the frame, starting with the middle intermediate horizontal element of the second type. In order not to be mistaken with twisting, it is better to draw lines on the outer side of the drywall sheet with a pencil corresponding to the axes of the frame elements.
After that, you need to fix the sheet to the upper and lower horizontal frame elements. If the panel is to be mounted on a wall, its verticality and the absence of distortions must be checked using a plumb line, and on the ceiling - using a level.
Then the sheet can be fastened with vertical posts. When tightening the screws, it should be noted that the distance from them to the edge of the sheet must be at least 20 mm. The pitch between adjacent screws should be 100-120 mm.

The instruction on how drywall should be mounted on the ceiling is not much different from how to mount the plasterboard on the wall. On the horizontal surface of the ceiling, a horizontal crate in the form of a frame is also arranged, which should be attached to the ceiling structures and aligned horizontally using a water level. For the convenience of its installation, it is also better to pre-mount the enlarged elements of the frame on the floor.
In order to mount a frame from a drywall beam on the ceiling and sheathe it with plasterboard, your hands may not be enough. An assistant may be required for installation. In exceptional cases, you can use supports and braces that can help you install drywall on bars alone, but this method should be used with caution, as unforeseen situations may arise associated with the fall and destruction of drywall sheets.
