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, moreover, working with them is accessible not only to an experienced builder, but also to a novice craftsman. Finishing walls with plasterboard without a frame and profile is possible using different adhesives and on surfaces built from various materials. The advantages of such fastening compared to the frame method are that the reduction in the area of the room is not so noticeable, a decent amount is saved on the sheathing elements, 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:
- 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 insulation material is installed exactly in frame structure, or if the wall has very large distortions that are difficult to level with plaster layers.
- Fixing sheets to the wall using self-tapping screws and polyurethane foam or on adhesive composition, made on a gypsum basis. Self-tapping screws and foam for fixing drywall are used if it is necessary to cover not only a wooden wall, but also surfaces made of 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:
- Plumb, building level and as a rule, preferably 1500 mm long - to control the evenness of the original wall and the created vertical plane.
- Electric jigsaw or sharp utility knife - for cutting drywall.
- Rulers of different lengths, a square, a tape measure and a simple pencil - for marking.
- Wide, medium and narrow spatula, as well as possibly a trowel (trowel) - for applying and distributing the solution.
- Construction float – for processing putty surfaces.
- Roller and brush - for treating walls with primer.
- Rubber hammer - for adjusting plasterboard sheets glued to the wall.
- Electric drill and mixer attachment - for mixing the solution.
- 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:
- Primer solution with antiseptic additives.
- Gypsum-based putty mixture, base and finishing.
- Dry mortar– drywall adhesive, or polyurethane foam.
- Serpyanka mesh tape - for sealing joints between sheets.
- 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.
- 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 construction and finishing mixtures, but also plasterboard sheets for various purposes- It is simple, moisture-resistant, fire-resistant and moisture-resistant finishing material:
- Regular drywall(GKL or, according to the Knauf proprietary classification - GSP-A) is used for rooms with normal humidity.
- 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.
- Fire-resistant sheets (GKLO or GSP-DF) are used for finishing walls around fireplaces, stoves, and chimneys.
- 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 a regular sharp stationery knife on hand. The cutting process takes place in next order:
- The sheet is placed on solid foundation- it could be large table, floor or several stools placed side by side at some distance from each other.
- Then, using a tape measure or ruler, the sheet is marked, with a simple pencil the necessary lines are drawn.
- The next step is to draw a knife along the drawn line, also along the ruler, which should cut top layer cardboard
- The sheet is moved to the edge of a hard surface and laid on it along the cut line.
- 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.
- The last step is cutting the cardboard on the other side of the sheet.
Drywall sheets allow you to level the walls, skillfully hiding any unevenness, create various protrusions and recesses, etc. The material is characterized by sufficient strength, it is easy to process and use, installation of such sheets can be done without any problems.
Once you understand the basic principles, you can level the walls of your house yourself or, for example, make a new partition. You just need to decide on the required shape of the finished result and choose the optimal method of fixing the sheets.
There are two main methods of attaching plasterboard sheets, namely:
- installation on a pre-built frame;
- frameless fastening with adhesive composition.
In some situations, to achieve best results The above methods are used comprehensively.
The base is assembled from a special plasterboard profile. At the end, all that remains is to screw the sheets to the frame using screws and perform the required finishing work. The disadvantage of frame technology is that the total thickness of the finished skin will be more than 4-5 cm, i.e. usable area the rooms will be significantly reduced.
Select the appropriate fastening method. If you want to fix the sheets as securely as possible, make a frame. It is important to maintain the existing quadrature - use the glue-based method.
Preparing walls for plasterboard covering
Covering walls with plasterboard requires several preparatory steps.
Before attaching the frame or gluing sheets, it is strongly recommended to get rid of the old wall covering. Carefully remove it down to the base. Additionally, dismantling the old trim will free up a few centimeters that can be used for new trim, preserving as much free space as possible.
This operation is not mandatory, but experts strongly recommend it. Additionally, the surface is treated with an antiseptic drug.
The third stage is preliminary marking. To begin with, it will be enough to mark the boundaries above the floor and below the ceiling from which it will begin and end. plasterboard walls. Traditionally, a distance of 50 mm is set aside.
Frame Construction Guide
The first stage is preparation of materials. To assemble the frame for drywall, a galvanized profile is used. The so-called fire is launched along the floor, ceiling and adjacent walls. UD profile. To fix such profiles, dowels are used.
The second stage is the installation of jumpers. After the starting profiles are secured, proceed to installing the vertical jumpers. The so-called is intended for this. CD profile. It is on this that the drywall will rest. The edges of the profile should “look” at the wall, and the wide side should look into the room. Fasten it using self-tapping screws designed specifically for galvanized profiles.
Secure the first main profile near the side wall. Attach the following in increments of 60 cm. B in this case the distance must be set from the center of the profiles being installed, and not from their edges. Under the next wall, the CD profile also needs to be fastened closely, regardless of the distance between it and the previous profile.
The third stage is strengthening the fastenings. To make the fixation of profiles more reliable, it is strongly recommended to use perforated hangers. These products look like galvanized strips with perforated ends. Such clamps need to be shaped like the letter “P” and secured with their centers to the wall, placing them under each profile installed vertically. There are “ears” at the edges of the element. Screw them to the profile. Check the evenness of the placement of all elements using a level and, if necessary, make adjustments.
If the height of the wall exceeds the length of one sheet of drywall (standard 2.5 m), add the missing piece of material from below or from above. At the joints, install jumpers from the CD profile you are already familiar with.
Installation of sheets and completion of work
The frame is ready, and you can safely move on to the main work. It is also performed in several stages and requires maximum care and responsibility from the master.
The first stage is the installation of plasterboard sheets. The material, as already noted, is attached to the main profiles. Fastening is carried out using self-tapping screws 3.5 cm long, made of hardened metal. It is more convenient, better and faster to screw in self-tapping screws using an electric screwdriver. Tighten until the fastener heads are flush with the drywall. The fasteners are screwed in increments of 100-150 mm in the center of the sheet and along its perimeter. Typically, the sheets initially have a center line, which makes installation easier.
The second stage is filling in the gaps. If one sheet of material is not enough to fill the entire available space, take a new sheet and cut pieces of the required size from it. Drywall can be cut wonderfully using an ordinary construction knife. Just cut the paper plasterboard sheet along the cutting line and carefully break the element, then cut the paper on the reverse side in the same way. Secure the remains and begin finishing.
The third stage is the finishing of the plasterboard structure. First you need to seal the seams. The sealing is done using a special self-adhesive mesh. The laid mesh must be puttied. Usually enough starting putty. This will allow you to get the most even surface possible.
To perform further work you need to decide what material will be used as the finishing coat. For example, in the case of laying tiles or other opaque thick material, you should simply putty the joints of adjacent sheets, wait until the putty dries and proceed to the finishing cladding. The putty is applied to the drywall with a layer of about 1.5-2 mm; there is no need for a thicker coating.
Sand the surface with sandpaper and then prime the walls. If further painting is planned, the surface should be as smooth and even as possible. If there are uneven areas, apply a new layer of putty, sand it and check the surface for unevenness. Repeat the described procedures if necessary.
If plasterboard walls are already made in small room, arranging a frame can become an unaffordable luxury, because... because of it, the total area of the room is reduced by several square meters. In such a situation the best option is to attach the sheets to the base using glue.
The first stage is surface preparation. It is strongly recommended to level the surface. Any kind of holes, bulges and similar defects will worsen the quality of adhesion of the sheets to the base. Use putty for leveling. After the putty has dried, prime the base.
Cut drywall into sheets the right size. Leave gaps about 5 cm wide above the floor and under the ceiling.
The third stage is preparing the mounting holes. Drill holes in the wall to accommodate the dowels. The fasteners must be screwed in so much that their caps form a single plane with the base.
The fourth stage is preparing the adhesive solution. The glue is prepared from a dry mixture specially designed for this type of work and clean water. Read the manufacturer's instructions. It contains a recipe for your specific glue, because... For different mixtures, the procedure for preparing the solution may vary. Consistency ready mixture will resemble a paste. The glue dries very quickly, so it is highly recommended to prepare it in small portions immediately before starting work. The specific drying time is also indicated in the instructions.
The fifth stage is gluing the sheets. Before attaching the sheets, the base must be thoroughly cleaned of any dirt and dust, because Dirt will reduce adhesion to the glue. Apply adhesive to the back of the sheets. Glue is applied along the center line and edges of the sheet in longitudinal strips, and in piles along the rest of the plane. Such piles should be made maximum every 25-30 cm. It is not recommended to level the piles into a continuous layer, because this will lead to a significant increase in the consumption of the solution, and will also not allow the entire area of the sheet to be properly docked to the wall.
Place the drywall against the base and press evenly. If necessary, you can tighten the fixation using a rubber hammer. In this case, you must first apply to the sheet wooden block and hit it with a hammer, otherwise you can punch holes in the coating.
Wait until the glue gains strength. Information about drying time must be given in the instructions. Please read this manual carefully before starting work and keep it until you are finished. Only after the glue has completely dried can you proceed to further steps.
In this case, the already familiar self-adhesive tape is also used. Apply tape to the seams and putty the joints so that they are at the same level with the main surface. Leveling is done using starting putty.
Finishing putty is used only when necessary, for example, when drywall is being prepared for painting. At the end, all that remains is to finish the walls with the chosen coating.
Thus, drywall allows you to obtain perfectly smooth and even walls without extra costs time and money costs. Select the most optimal method for fastening sheets for your case and proceed with installation. Follow the instructions and do not forget the recommendations received.
Good luck!
Video - Cover the walls with plasterboard yourself
How to properly cover a wall with plasterboard? Which tool and plating method should I choose? We will try to briefly talk about this and other things in the article, so that even a beginner has no doubt that he can do it with his own hands.
First you need to inspect the scope of work, assess the scale and select the necessary installation method.
As you know, the walls of private houses and apartments are made of reinforced concrete, brick and wood. Drywall can be glued to any of these surfaces or a frame can be installed. The main criteria influencing the installation method are the volume of the room and the curvature of the walls. Sheathing with plasterboard on a frame is considered the most optimal, but here the disadvantages should also be taken into account - the area of the room with the installed frame will be significantly reduced (the total thickness of the sheathing will be more than 5 cm). Therefore, if you are planning to renovate a small room, perhaps the best option There will be a frameless fastening with an adhesive composition. If the defects and curvature of the walls do not exceed 20 mm, you can safely choose it, i.e. Glue the gypsum board with gypsum glue.
If we have more or less figured out the mounting methods, then the question regarding the tool remains open.
Tool for the job
To cover surfaces using frame technology you will need:
- The material itself is plasterboard sheets.
- Pencil, knife for cutting plaster sheets, blades.
- Tape measure, building level, preferably laser
- Metal scissors
- Dowels 6x40, 6x60.
- Galvanized profiles CD, UD.
- Perforated hangers (CD bracket)
- Grinder, drill, screwdriver.
- Metal self-tapping screws for gypsum boards
- A cutter, or self-tapping screws (bugs) for attaching profiles to each other
- Planer for smoothing edges
- Spatula and bucket, gypsum glue (if we glue plasterboard)
- Everything for finishing plasterboard seams
Surface preparation
Covering walls with plasterboard with your own hands involves not only installation, but also preparation. Before covering the surface, you need to perform several preparatory work:
- Delete old finishing. Before you begin finishing, you need to remove all previous layers from the walls to the base.
- Treat the walls. This procedure is not considered mandatory. However, experts recommend priming the walls and treating them with a special antiseptic.
- Make preliminary markings. Mark boundaries above the floor and below the ceiling where the slabs will begin and end. Usually a distance of 5 cm is maintained.
Methods of fastening gypsum boards: advantages and disadvantages
As mentioned earlier, there are only two ways to cover walls with plasterboard: gluing and mounting the slabs on a metal or wooden frame. To better understand which method is better to choose, let's consider the advantages and disadvantages of each of them.
Frame method
The advantages of installing on a galvanized frame include: mechanical strength and reliability of the finished structure, the possibility of installation soundproofing material, installation of the material even on the most uneven surface. In addition, the structure installed on the frame can support the heavy weight of the tiles. Therefore, this option can be used in the kitchen or bathroom.
The method of installation on a wooden frame has the same advantages as the method of installing gypsum boards on a metal frame. The only thing worth considering is that wood does not tolerate moisture well, so this installation method is not suitable for rooms with high humidity.
Disadvantages frame method installation can be called additional financial expenses on the necessary fasteners and the complexity of installation.
Frameless method
Wall cladding gypsum board frameless way a little simpler. It will not take away useful centimeters of your room and will not force you to shell out a tidy sum for repairs, but it will be less durable compared to frame technology. The disadvantages of this method include the impossibility of laying soundproofing material.
Technology for installing sheets on galvanized profiles
To assemble the frame, we take a galvanized profile. We run a UD profile along the floor and ceiling, which we fix with 6x40 dowels. After securing the starting profiles, we proceed to the installation of vertical jumpers (CD profile). The edges of the profile should face the wall, the wide side should face the room.
The profile is cut to the required size using metal scissors or a grinder.
We secure the profile with self-tapping screws specially designed for galvanized profiles. We attach the first main profile near the side wall, the next ones in increments of 60 cm. We set the distance from the center of the profiles, and not from their edges. We fasten the profile closely under the next surface, regardless of the distance between this and the previous profile.
To enhance fixation, it is recommended to use perforated hangers. The products externally look like galvanized strips with perforated ends. We give these clamps the shape of the letter “P” and fix them with the middles to the wall under each vertical profile. At the edges of the perforated hangers there are so-called “ears”. We screw them to the profile and check the evenness of all elements with a building level.
Sound and heat insulation material is laid between the wall and the plasterboard sheet. Special mineral wool for hl. After which, it is advisable to lay a layer of vapor barrier film.
If the height of the wall exceeds the height of the plasterboard sheet, you can add the missing part of the material from above or below by installing jumpers from the CD profile.
How to sheath a prepared frame
Plasterboard sheets are fixed to the main profiles. Fastening is carried out with self-tapping screws 3.5 cm long. For quick and easy work, it is best to use an electric screwdriver. We tighten the screws until their heads are “recessed”. The fasteners are screwed at a distance, within 150 mm in the center of the gypsum board and around the perimeter. If one sheet is not enough, take a new sheet and cut pieces of it to the desired size.
Sealing gypsum board joints
Now you can start finishing. The technology is described in detail in the article. Using a special self-adhesive serpyanka tape, we seal the seams. We fill the tape with a special fugen putty from knauf. For finishing touch It is worth deciding what material will be used for the finishing coating. For example, if you are laying tiles or other fairly dense material, you can simply caulk the seams and start laying the tiles. If wallpaper is glued to the surface or simply painted, then we coat the seams and screw holes several times.
We sand the surface with sandpaper and treat it with a primer. If the sheets will be painted in the future, the surface must be perfectly flat.
Frameless sheet installation technology
The first stage is priming the surface. We prime and wait for it to dry completely.
The next step will be preparing the adhesive solution. IN clean water add Perflix, mix, achieve the thickness of the solution we need. It is advisable to mix it thicker so that it does not flow down with the drywall. I will warn you right away that the glue dries quickly, so you need to work with it quickly.
A sheet of drywall can be easily cut with a knife and then broken off. The edges remain torn; here we will need a drywall plane.
Apply glue only to areas that are free of dust and debris. back surface leaf. In the center and edges of the gypsum board glue is applied in dollops of the desired thickness. They are made at a distance of 25 cm. If you need to glue a whole sheet, then you can apply the buns to the wall.
We apply the plasterboard sheet to the base and press it evenly. For better fixation You can use a rubber hammer. We apply a block of wood to the sheet and hit it with a hammer. You cannot hit the gypsum board itself with a rubber hammer, otherwise you may punch holes in the material.
Only after the glue has completely dried can you begin to seal the seams. The seams are sealed using the same principle as when installing on a profile.
In conclusion
Sheathing with plasterboard will not give you special troubles, if all stages are performed sequentially.
- It is necessary to prepare the walls (clean them of old coating, dust, dirt, treat them with a primer).
- Select the method of securing the material (frame, frameless).
- Purchase the necessary equipment.
- Secure the plasterboard sheets.
- Seal the seams special tape, putty, treat the uneven surface with sandpaper and prime.
Often for wall decoration used drywall. The choice of this material is explained by a number of its useful properties and features.
Drywall
For example:
- Drywall is fire resistant;
- Moisture-resistant material;
- Characterized by high level soundproofing;
- Quite durable material;
- Flexible and plastic (plasterboard is often used to create curved surfaces in the interior).
Another significant advantage of plasterboard is that the walls do not need to be plastered and finished before perfect condition. And this saves not only time, but also money.
Walls covered with plasterboard After the drywall is “mounted”, it can be painted, whitewashed or wallpapered. But there is one point. Once the drywall is attached to the wall, the heads of the screws or nails remain visible. They must be covered with enamel or alcohol varnish before wallpapering. Otherwise, they will rust, and unsightly red spots will appear on your new wallpaper. One more note: lime paint does not adhere well to drywall, so it should not be used.
Drywall installation
Drywall panels can be used to decorate any wall, be it wood, brick, stone or concrete. Only the fastening tools (screws, nails, screws, self-tapping screws, adhesive mastics and adhesives) will be different.
Plasterboard wall covering If you are going to install panels using mastic, you should prepare the walls in some way (remove grease, soot and other contaminants, make markings according to which the drywall will be attached). When installing this way, remember that the height of the panel must be equal to the height of the room. The presence of a horizontal joint is simply unacceptable. Before installation, all irregularities should be removed from the wall.
Correct application bridges The mastic is applied to the panel or directly to the wall (“cakes” are placed in a checkerboard pattern at a distance of 35-45 cm from each other, and where the edges of the sheet are, the mastic is applied in a continuous strip).
Metal frame After the sheet is placed against the wall, it should be pressed with even blows on the sheet.
When drywall cannot be attached to the wall using glue or mastic, you should use metal profiles or wooden frames. These structures are attached to the wall using dowels or self-tapping screws. Everything is done with the following calculation: under each sheet of drywall there should be two vertical bars or profiles (along the edges of the panel). If the width of the drywall exceeds 50 cm, you can use an additional vertical bar or profile in the middle part of the frame.
Drywall is attached to the frame using screws, self-tapping screws and nails.
Upon completion drywall installation The seams between the sheets should be sealed with tape, of which there are many varieties. It is better to use tape with a “rough” surface. Due to this, there is good adhesion to the putty.
Finishing walls with plasterboard video
Plasterboard sheets (GKL) are an excellent substitute the usual way 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. Specifications plasterboard allows you to use it for finishing inside 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:
- According to the frame.
- 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 a 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, first securing the sheets with an adhesive composition, and after it has dried, with self-tapping 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
Walls and ceilings made of plasterboard are painted, covered with wallpaper, plain or for painting, 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 to hang various objects 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.
It is necessary to maintain strict verticality, 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. TO wooden walls The frame elements are fastened 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.
In places where sheets meet in height, additional horizontal profiles. 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 needs to be fastened in one direction, for example from left to right from bottom to top. If you fix the sheet in different angles, with further fastening it may bend.
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 a 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 the rough ceiling, and drawing lines using a marking cord. Mounted on the wall damper tape, 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.
