Frameless fastening of drywall to a wooden wall with self-tapping screws. Methods for attaching drywall to a wall

Drywall is one of the most popular finishing materials due to its many advantages: ease of installation, safety, possibility of use in the most different rooms and a relatively low price. Let's talk about whether it is possible to cover walls with plasterboard without a frame.

Features of the use of gypsum boards

Drywall is used to mask uneven walls and build partitions. At the same time, not only an experienced builder, but also a less experienced craftsman can work with this material. Installation is possible on various adhesives and base surfaces.

Important! The advantage of this method over the frame method is that the useful volume of the room is “eaten up” to a much lesser extent. At the same time, labor intensity finishing works is small and can easily be produced independently.

Frame VS frameless method - which is preferable?

To be fair, it must be said that sometimes installing plasterboard sheets on the frame is the only way to finish. Let's try to compare these two fundamentally different techniques and determine the scope of their application.

Frame method

For the manufacture of frames, metal profiles or wooden beams are used. This method is used if additional thermal and sound insulation of the room is needed. They also use installation of sheets on the frame if the walls are uneven and cannot be leveled with plaster.

Frameless method

Installation of drywall on walls without a frame is carried out using an adhesive compound with gypsum or using construction foam and self-tapping screws:

• Gypsum adhesive is preferred for concrete and brick walls.
• Fastening plasterboard sheets with self-tapping screws is used for wooden walls.

Important! There is a limitation on the height of the walls (it should not exceed 3.0 m).

Required Tools

To level the walls without first making a frame, use the following set of tools:

• A 1.5 m long building level is used to control vertical planes.
• Jigsaw - for preparing plasterboard sheets.
• A set of marking tools: pencil, rulers, squares.
• Spatulas of different widths for applying the solution.
• Construction grater.
• Paint roller and brush - for applying primer.
• Rubber hammer.
• Electric drill with mixer attachment.
• A screwdriver - if you need to fasten the sheet also with self-tapping screws.

Materials you will need:

• Primer with antiseptic.
• Basic and finishing putty on a gypsum basis.
• Construction foam or special adhesive for drywall.
• A tape made of serpyanka mesh to hide the joints between the sheets.
• Long length self-tapping screws. Their length depends on how smooth the surface is. The depth of penetration of self-tapping screws into the wall is from 50 to 60 mm.
• Foam rubber (optional).

Types of drywall

One of the best is the products of the Knauf company. The company is engaged not only in the production of construction and finishing mixtures, but also drywall with different areas of application:

• Normal - used for rooms with low humidity.
• Moisture resistant - used for bathrooms and toilets. Tile tiles can be installed perfectly on such a surface.
• Fire resistant. Great for the fireplace area, near the stove and/or chimney.
• Fire and moisture resistant. Suitable for finishing walls in attics, lofts or the boiler room of a private house.

Important! Cutting a sheet of drywall is a pleasure. No special devices are needed. A well-sharpened utility knife is sufficient.

Cutting order

In any case, this process will have to be performed, regardless of whether you plan to cover the walls with plasterboard without a frame or with it. The plasterboard sheet is cut in this order:

1. Place the sheet on a flat horizontal base.
2. Mark the sheet using a ruler or tape measure, draw the necessary lines with a pencil.
3. Using a ruler, draw a knife along the outlined line.
4. Slide the sheet over the surface and place it along the cut line.
5. Press the edge of the sheet and break it.
6. Cut the cardboard on the other side of the sheet.

Mixture for installing drywall on a wall without a frame

This composition is produced on a gypsum base with plasticizers, which ensure strength and good adhesion of the solution. Any adhesive mixture for frameless installation must meet the following requirements:

• Minimum setting time.
• Slight shrinkage when drying.
• Homogeneity and plasticity.
• Easy to apply.

Important! Please note that gypsum mixture was not expired, since it has a short shelf life - usually no more than six months. It is not advisable to purchase the mixture in bulk.

Usage time ready solution- about half an hour, so it’s better to cook it in small portions. If the mixture begins to set, there is no way to dilute it.

Important! Experts advise buying all materials for covering walls with plasterboard using glue from one manufacturer (the same “Knauf”), as they interact perfectly with each other.

Polyurethane foam

This is a fairly popular material, and different types have different characteristics. Different foams different ratio extensions, so be sure to check their characteristics in advance. There are 2 types of mounting foams:

• One-component, ready-to-use polyurethane compounds. They are sold in cans.
• Two-component. These mixtures are used by professionals, since their preparation requires special equipment and precise proportions.

The advantages of using polyurethane foams are as follows:

• Good adhesion to a wide variety of materials.
• Resistance of the material to temperature changes.
• Foam is a dielectric - it does not conduct electricity.
• Good sound insulation properties.
• Easy to install, quick drying.
• No toxic substances.
• Fire safety.
• Moisture resistance.
• Small (no more than 5%) shrinkage.
• High strength indicators.
• Good thermal insulation effect.
• Plasticity, elasticity, filling gaps and cracks.

How to cover walls with plasterboard without a frame - installation work

The entire cycle of work when covering walls with plasterboard is divided into several stages.

Preparation

The first stage is high-quality surface preparation:

• If the wall is painted oil paint or enamel, which “can’t be torn off even with your teeth,” make notches across the entire surface to ensure better adhesion. A hammer drill with an attachment or an ax is suitable for this.
• Be sure to seal cracks and cracks in the walls. Fill them with polyurethane foam, and after it hardens, remove the excess with a sharp knife.

Important! For small defects Cement-sand mortar is also suitable.

• Clean the wall surface from dust using a wide brush or vacuum cleaner.
• Treat the wall with a primer and antiseptic. This not only significantly improves adhesion, but also prevents the development of fungus, mold, and harmful insects. Leave the finished wall to dry completely.
• After the wall has dried, check its verticality using a building level or plumb line. If there are significant distortions, the wall will have to be leveled.

Alignment

There are several ways to level walls.

Method 1

To implement it you will need gypsum adhesive and pieces of drywall (kind of beacons):

• The pieces can be square or strip-shaped.
• Their number depends on the degree of unevenness of the wall.
• Having determined the highest and lowest points on the wall, bring the latter to the same level as the first.
• Now all that remains is to accurately draw out the remaining surface.

Important! Sometimes plasterboard overlays are made in 2 layers. The beacons attached to the solution after the solution has hardened serve as a support for the finishing sheets.

Method 2

As in the first method, start leveling by finding the “maximum and minimum” points. Next, start screwing self-tapping screws into the wall at intervals of 20-30 cm so that their heads are at the same level.

Important! In this case, self-tapping screws act as support for the plasterboard sheets. Mount the sheets with adhesive and you will have a perfectly vertical wall.

Installation of drywall on construction foam

This method is suitable for uneven walls. In addition, it makes it possible not to delay finishing work too much.

First, prime and dry the wall well, and then:

• Mark 8-9 points on the sheet where it will be attached to the wall.
• Drill holes in them for self-tapping screws.
• Place the sheet against the wall and make marks on it through the slits.
• Remove the sheet, and using the resulting marks in the wall, drill holes 5-6 cm deep for the dowels.
• Drive dowel plugs into the wall holes.
• Glue 12-15 pieces on the opposite side of the sheet. square pieces of foam rubber 15x15 cm. The thickness of the foam rubber is 1.5-2.0 cm. In case of significant distortions, it is advisable to stick the foam rubber on the wall. The distance of the foam rubber from the dowels is from 10 to 12 cm. The foam pieces in this case serve as shock absorbers.
• Attach the sheet to the wall by tightening the screws through the pre-prepared holes. Constantly check the correctness of fastening using a building level.
• Do the same with all sheets.
• Upon completion of installation, drill a 7-8 mm hole at a distance of 2-3 cm from each of the screws. Pump mounting foam through the holes into the space between the wall and the plasterboard sheet.

Important! The foam hardening time in this case is at least 24 hours, since the process takes place without air.

• Carefully cut off the excess construction foam that came out through the holes with a knife.
• After the foam has hardened, unscrew the screws. They are no longer needed.
• Reinforce the joints between the sheets with sickle tape, and then treat them with putty. After the putty has dried, treat the joints sandpaper or a mesh made of abrasive material.
• Prime, putty and dry the wall, then clean it so that the surface is smooth.

The wall is ready for decorative finishing!

Do you want to line the partitions in your apartment with plasterboard, but it’s a pity to lose precious centimeters that are already missing? Install drywall on unframed walls. This method is even simpler - you don’t have to bother with installing the profile. It will save space and create equally ideal surfaces. Even without extensive experience in repairs, you can cope with this task on your own.

Advantages of leveling gypsum board walls without a frame

This method of installing gypsum board sheets:

1. Economical in materials.
2. Takes less time.
3. Produces less debris and dirt.
4. Installation and finishing are completely done by yourself, so you can feel like a pro.

To install gypsum board sheets on the wall, you need to purchase special adhesives. The most popular of them are the Knauf and Volma mixtures. You can also mix gypsum putty with a small amount of PVA glue.

The essence of the frameless method of fastening a gypsum board sheet

Installation of drywall on walls without a frame is carried out using special staff. They glue the sheet onto the base surface. The joints are puttied and reinforced with tape. After priming the wall is ready for finishing– wallpaper, decorative slabs can be pasted onto it, or it can be painted at your discretion.

Since the sheets themselves are thin, total area the room is almost unaffected. They are convenient to use when leveling walls small rooms: bathroom, storage room, loggia, and in other places where every centimeter of space is important.

Preparing walls for gluing plasterboard sheets

Before you begin installing drywall without a frame, you must.

• It is easier to remove wallpaper with a spatula, after wetting it with water using a sponge or spray bottle. An excellent soaking effect is obtained when using a steam generator.

Paint with concrete wall it is difficult to remove, but necessary, otherwise the composition for gluing gypsum plasterboard will either not stick to it or will tear it off from the base. As a result, the sheet will not hold.

• Old plaster is tapped to detect hidden delaminations. Remove damaged and suspicious parts to a solid base.

If the layer of plaster is thick over the entire wall, it makes sense to remove it entirely using a hammer drill or a hammer and chisel. This will help save additional centimeters of usable space.

Additional wall treatment

Proper wall treatment before attaching drywall sheets to an unframed wall is extremely important.

• Inspect the wall itself - repair cracks, fill in holes from old communications, and apply mortar to the places where large pieces of plaster have fallen out.
• If necessary, make recesses for sockets, switches and wiring. Wires and junction boxes must be installed.

Wire insulation latest generation allows you not to pack them in fireproof corrugation, so it’s enough to simply attach them to the wall with clamps.

• Remove debris, use a brush or vacuum cleaner to collect dust from the walls and floor.
• To ensure that the glue adheres firmly to the surface of the wall, it is primed evenly. In areas with fresh plaster, the primer is absorbed more strongly, so here it is applied in two or even three layers.

When installed under the gypsum board sheets, a poorly ventilated air gap remains. In rooms with high humidity, they create optimal conditions for the development of various types of rot and fungus. Treating the base wall with an antiseptic will help avoid this danger.

• Since the gypsum board sheet has large dimensions (2500 x 1200 mm), clear a suitable flat area on the floor for working with it.

GCR can be installed only when the wall is completely dry, after all the procedures have been carried out.

Technology of frameless installation of plasterboard sheets

Before gluing drywall to the wall, you need to set general level. Using the installation rule and a plumb line, vertical surface deviations are measured. The length of the wall alignment line is marked on the floor and ceiling.

A sheet of gypsum board is cut out onto the entire wall at once. To reduce the amount of work, it is better to buy sheets the height of the room or larger. Then you won’t have to adjust and putty the horizontal joints.

GCR can be attached to walls in two ways.

Attaching the sheet with glue

The fastening technology will differ slightly depending on the degree of curvature of the walls.

If the differences on the wall are less than 4 mm, then the adhesive composition is evenly applied to the perimeter of the gypsum board sheet using a notched trowel. The sheet is placed in the chosen place, pressed and leveled by applying a rule to the surface and tapping it with a rubber hammer, not forgetting to check with a building level.

Important! The adhesive solution sets quickly. Find out experimentally what volume needs to be diluted in order to have time to produce it in one go.

A wall with a level difference of up to 2 cm will require thicker glue. It is applied to the surface of a sheet of drywall in cakes about 5 cm high at a distance of 30 cm from each other. Installation is carried out similarly to the method described above.

If the wall has differences of 4 cm or more, it is necessary extra work. In the recesses it is necessary to glue additional beacons from gypsum board scraps. There is another method: fill the desired area with polyurethane foam, and after it dries, cut it at a general level.

Subsequently, the adhesive composition is applied to the dried beacons and directly to the wall. The sheet is pressed against the glue and aligned in all directions.

Fastening the sheet to the wall using polyurethane foam

Covering walls with this method is more labor-intensive, but it will provide greater reliability of fastening, regardless of the curvature of the surface.

• The gypsum board sheet is pressed against the wall. In its corners, and in another 4–6 places, holes are drilled in the wall, making marks. The sheet is moved to the side, and the resulting marks are drilled out and dowels driven into them.
• On the sheet, stepping back from the holes by 10–15 centimeters, glue pieces of the shock absorber (foam rubber, foam rubber). This distance is necessary for free expansion of the foam. The thickness of the sponge depends on the differences on the wall. Ideally they should be the same.
• The sheet is placed against the wall. Screws with wide heads or an attached washer are screwed into the dowels. They also regulate the level, creating flat surface. The remaining sheets are installed in the same way.
• After checking the rule, a hole is drilled near each self-tapping screw. The tube for pumping polyurethane foam should fit into it without effort. Foam is pumped into the cavity through the hole. It should form a cushion between the wall and the sheet. The amount of foam is determined experimentally in advance. After the foam has hardened, the screws are removed.

Don't rush to finish the wall decorative materials. The adhesive base sets quickly, but it will take at least a day to dry completely.

A few words about safety precautions

Working with gypsum boards generates quite a lot of dust. Inhaling it will not add health to anyone, so it is better to protect yourself with a respirator. You should also ensure that dust does not penetrate into living spaces by curtaining the openings with a damp cloth.

Drywall - universal construction material for wall decoration. Today, it is very fashionable and beautiful to use gypsum for finishing surfaces. The demand for this material is growing every day. This material has high elasticity and elasticity; it is these qualities that allow you to create various unique designs on surfaces, and many people can do this on their own. Using drywall, you can remove all the unevenness from the wall, while making it as smooth as possible. In this article, I will teach you how to attach drywall to a wall.

Attaching drywall to a wall is a whole science, which, at the same time, allows you to create magnificent arches, built-in wardrobes, partitions, niches for a TV and many other interesting decorations. Let's look at three main ways to create a new design in your home.

Frameless method

IN this option mounting occurs directly on the wall, which must first be prepared. This mounting option will hide unevenness on the wall. This method is the simplest compared to other methods.

So, let's look at how to attach drywall to a wall in a frameless manner using glue.

Wall preparation process

An important point before starting work is preparing the walls. In order for the sheets to attach well to the base, it needs to be well processed.

It is necessary to thoroughly clean off the old coating: wallpaper, paint, whitewash. We look for irregularities on our wall and mark them somehow (maybe with chalk). We apply a primer to the wall (the primer must be applied in several layers so that the wall has good adhesion) and let it dry well. You need to cut strips 10 cm wide from drywall (for cutting you can use a regular stationery knife

). Apply primer to one side and wait for it to dry. While the primer dries, you need to mix the glue for gluing in a separate bucket. It is best to use a drill with a special attachment - it is very convenient and will save you time. The consistency of the finished glue should be like the consistency of sour cream.

and progress of work

The next step is to stick the same strips only horizontally. The stripes will be interrupted in those places that are marked as unevenness, and will begin behind them. This way we can even out all the defects on the wall. Now it’s clear how smooth the wall will be. So, everything is ready, all that remains is to glue the sheets.

Wall mount

Apply a primer to the sheet and wait until it dries completely - this will ensure good adhesion of the material. After the primer has completely dried, apply glue to the sheet. It is very important when applying glue to follow the rule: in places where the material will adhere to the strips that are already on the wall, apply the glue using a notched spatula (increasing adhesion).

In other areas, the adhesive material is applied in the form of “bloopers”. After applying glue to the sheet, it must be firmly glued to the wall. And so on for each subsequent sheet. This is how frameless gluing occurs.

Installation on a metal frame

This installation option is very complex, since its implementation requires many sequential actions. The advantage of this method is that it is possible to level out large unevenness on the walls, and it is also possible to use thermal insulation between the plasterboard sheets and the wall. By using metal profiles to create the frame, we increase the service life of our structure. This installation method is best suited if you decide to make a niche for the TV out of plasterboard.

Getting started on plasterboard construction, which will eventually become a wardrobe, a shelf for books or even a TV, the first thing you need to do is measure the walls in order to have a clear picture - at what distance to place the profiles and hangers (usually at a distance of 60 cm from each other). Along the perimeter of the wall, profile guides are attached using dowels. They need to be set using a level (we are creating a flat surface).

). Apply primer to one side and wait for it to dry. While the primer dries, you need to mix the glue for gluing in a separate bucket. It is best to use a drill with a special attachment - it is very convenient and will save you time. The consistency of the finished glue should be like the consistency of sour cream. How to apply decorative plaster: tools, materials, technologies

Having installed the upper profile, from it, using a plumb line, dowels and screws, we install the lower one. Next, the side profiles are installed and the hangers are attached. The load-bearing parts of the frame are installed in the guides. The supporting profiles will support the gypsum sheets.

As a result, we should have a lattice wall created using profiles and hangers. Knowing that the width of the sheet is 120 cm, the supporting profiles need to be positioned so that there are three of them per sheet.

To ensure good sound insulation and thermal insulation, insulation is laid between the plaster and the wall. So, the frame is completely ready, you can attach the plaster sheets. It is attached using self-tapping screws (black 3.5x25 mm), the head of which is drowned. It should not stick out, otherwise it will interfere with further processing with plaster.

It is important to remember that the sheets must be fastened in such a way that their joint is on the same profile. The seams and holes from the fastening must be filled with putty.

Mounting on wooden slats

The third method of attaching plasterboard sheets to walls has a number of advantages. It is cheap because it uses wooden blocks rather than a metal profile. It is much simpler, which means it saves time. Using this method, you can also get rid of uneven walls. The difference from the method with metal profiles is that the fasteners wooden beam occurs directly to the wall itself, and not to the ceiling and floor.

The first step is to visually determine the lowest point of the ceiling; this will be the starting point. A beam is attached to the ceiling; it must be leveled using a level. Then a plumb line is thrown from it, it will determine the plane. If the plane does not coincide, you need to put a lining under the lower beam or trim the scarf a little.

Having dealt with the lower section, we move on to the side guides. It’s a little easier here, if the plane is already installed, all that remains is to adjust them to the level. The timber along the contour is installed, it’s time to start lathing. Two types of timber are used for lathing: 40x40 mm and 80x40 mm. Must be observed important rule: for each sheet you need to use three beams, one in the middle (40x40mm) and one on each edge (80x40mm).

No renovation nowadays is complete without drywall. Walls are constantly sheathed with this material, various structures are made from it, and ceilings are finished with it. As a rule, to install plasterboard sheets, a frame is first mounted on which the material is fixed. However, more and more often people are trying to attach drywall to the wall without a profile. What is this connected with? First of all, with the desire to save time, money and labor resources.

But is it possible to attach drywall directly to the wall? The question is ambiguous. Experienced craftsmen It is recommended to mount metal or and then attach gypsum sheets to it. However, when correct installation, you can install drywall on walls without a frame. However, it is better to think everything over several times and unless the decision has no alternatives, proceed with the matter, since fastening gypsum boards without a frame just for the sake of saving money can result in large costs in the future. fasten gypsum board this way You can, for example, if you are renovating small rooms, such as bathrooms, toilets, balconies, then the frame will steal precious space.

One of the exotic ways to attach drywall without a profile is.

What is this article about?

Conditions for fastening without profiles

In order to attach gypsum plasterboard or gypsum fiber board directly to the wall, you need to follow a series of necessary conditions, Without which this procedure is simply impossible.

The wall must be vertical and perfectly level, that is, not have even the slightest slope. There are situations when the wall is not level enough and in such cases the frame is partially installed. Metal profiles in this installation option serve only as a leveler for the wall.

The height of the room should not exceed the length plasterboard leaf. The problem here is that when installing plasterboard sheets, it is assumed that the joints of different pieces of plasterboard will be located along the transverse metal profiles. If you attach the sheets directly to the wall, then you should not have transverse joints at all, since there will be nothing to attach them to.

If the wall has minor unevenness from two millimeters to two centimeters, then there is an option to level it with starting putty, to which ten to fifteen percent of gypsum must first be added. To attach drywall, it is recommended to use ready-made adhesive mixtures. The mixture must be applied around the perimeter of the entire sheet, as well as in one continuous strip in its center.

If the unevenness is much greater, then instead of frame profiles you can use plasterboard beacons. They are plasterboard, cut into squares or rectangles of ten to twenty centimeters and serve to level the wall plasterboard sheets without frame.

After glue mixture When dry, the plasterboard sheets are again secured with dowels in the corners and in the center. The dowels are attached so that they extend into the wall by at least forty millimeters.

After the final installation of the sheets has been carried out, it is necessary to putty the connecting seams, and also glue the mesh.

Required Tools

For finishing you will need some non-standard tools. It's better to prepare them in advance.

• Knife with replaceable blades for cutting plasterboard sheets;
• Electric jigsaw or saw for working with drywall;
• Strong thread. It will be useful to create a plane level;
• Nails or screws;
• Building level;
• Simple pencil;
• Plumb;
• A scraper to clean up the edges plasterboard leaf;
• Drill, whisk and bucket to dilute and stir the solution;
• Putty knife. It is better to take two spatulas - wide and narrow;
• Rubber hammer;
• Regular hammer;
• Pliers;
• Phillips screwdriver.

Let's also consider the materials that will be used during the work.

• Plasterboard sheets;
• Glue, for working with plasterboard sheets. You can also use starting putty if you add ten percent gypsum or PVA glue to it;
• Water;
• Primer;
• Dowels. The size of each dowel should be from eighty to one hundred and twenty millimeters;
• Serpyanka;
• Glue.

Preparation for installation

If you are going to finish a brick or concrete wall with plasterboard, then you must first clean it and spray it with a solution. Then the surface needs to be primed. The soil must be diluted strictly in accordance with the instructions provided by the manufacturer. If it says on the package that the primer is ready for use, then there is no need to dilute anything. You can immediately begin processing the wall.

If preserved on the wall old plaster, it is tedious to carefully examine it in order to identify weak points and treat them with a solution and then with a primer.

It is strictly forbidden to attach plasterboard sheets to walls in rooms where there is constant dampness. And also, this type of repair cannot be carried out if condensation remains on the walls of the room. This will seriously damage the fastening of the sheets. In such rooms it is necessary to use special moisture-resistant plasterboard and attach it only to the frame.

Before attaching drywall, it is necessary to inspect using a level and plumb line for deviations from the vertical and in alignment. If this is possible, then all convex areas must be knocked down and the depressions covered with mortar in order to perfectly level the surface before installation.

After priming, markings are applied to the wall using a pencil or chalk. If you do this before priming, then all the drawings will simply be washed away. Drywall sheets on the side attached to the wall also need to be coated with a primer before fastening. Beacons need to be cut out of waste plasterboard sheets and coated with primer on both sides.

If this is necessary, the next stage of installation is the installation of electrical wiring. In cases where the wire must run on wall projections, it must be buried in drywall. To do this, you will have to make special grooves in the sheet.

Mounts on flat and curved surfaces

If the wall surface is relatively flat, then there is no need to use beacons. Use a mixer to dilute the dry powder in water and make glue. If you don't have a mixer, you can make glue by hand, but then the process will take much more time and effort.

If you decide to add PVA glue to the putty, then first you need to dilute the glue in water, and only then add the dry powder. If you do the opposite, the putty will very quickly harden and turn into stone. Naturally, after this, it will no longer be able to be used for its intended purpose.

Apply glue to plasterboard sheets in one continuous strip around the entire perimeter on all edges. You also need to apply several cakes of the solution in a checkerboard pattern in the center of the sheet. The distance between the cakes should be about forty centimeters. To make the fastening sufficiently reliable, you need to coat more than a tenth of the surface with glue. plasterboard leaf.

Attach the sheet to the wall strictly vertically. It must be applied and pressed against the wall. It is best if someone helps you with this, since it is problematic to complete this process alone. Check how firmly the sheet is attached. If you have any doubts, press it harder in those places where the lag occurs. It is to take into account such subsequent adjustment that enough solution is applied to the sheet. If the solution is not enough, then theoretically the sheet can be peeled off, but it is better to avoid such situations, since during the peeling process the plasterboard sheet may simply break.

If the wall is tilted or rotated, you will have to use beacons. Use strong thread to create a net that indicates the desired verticality and plane. Next, the beacons are installed in the right places. They need to be installed so that they touch the thread frame. Then the drywall sheets are attached in the same way as in the first option. After this, secure the problem areas with dowels, and seal the seams with putty and sickle.

If you are attaching plasterboard sheets to wooden wall or the ceiling, then everything is much simpler. To install such sheathing, it is enough to screw the sheets to the wall with self-tapping screws or self-tapping screws. If the wooden wall is not level, this can be corrected by applying additional wooden overlays, and all bulges can be removed with a regular plane.

As you can see, there are different ways installation of plasterboard sheets, however, the most reliable way installation of gypsum boards - installation on metal carcass. This is the only way the sheets will hold firmly enough.

Installation of plasterboard sheets is carried out in two main ways: on the frame or directly on the wall surface. In most cases, plasterboard is mounted on walls without a frame in rooms with small area, since the lathing takes up a lot of space and narrows the space. How and in what way frameless installation is carried out will be discussed in this article.

The frameless method of installing drywall is most often used in rooms with small areas.

Advantages and disadvantages of frameless drywall installation

The frameless fastening method has the following advantages:

• Saving money spent on installation of sheathing.
• Quick installation. Mainly duration installation work caused by the construction of a frame, and in its absence the process accelerates.
• This method allows you to save more free space, since the lathing takes up at least 5 cm usable area every wall.

Flaws:

• If the humidity of the walls is high, drywall will quickly become unusable, even taking into account the use of moisture-resistant material.
• Finishing walls with plasterboard without a frame and profile is possible only with minor surface unevenness.
• The maximum permissible difference is 2 cm, but no more. For more significant differences, it is necessary to level the surface or use another method of fastening finishing material.
• When using the frameless method, there is no way to hide communications.

Preparing everything you need

To attach drywall without a frame, you need to plan the work and prepare everything you need:
Tools and material:

• Jigsaw.
• Drywall (the quantity is calculated taking into account the area of ​​the walls of the room).
• Gypsum mixture.
• Level.
• Roulette.
• Container for diluting adhesive solution.
• Metal brush.
• Plaster mortar.
• Putty knife.
• Primer.
• Hammer.

Take measurements of the room and, based on the results obtained, cut the material. Measurements are also necessary to select the most appropriate option for the location of the material. If the standard height of the room is exceeded (2.5 m), it is necessary to prepare special inserts that will close the resulting gaps.

When calculating and cutting the material, you need to take into account that the arrangement of the sheets should be offset - to prevent the appearance of cross-shaped joints.

Before installing drywall, you need to prepare the wall: clean it of whitewash, wallpaper and paint. Existing holes must be plastered.

Wall alignment

Preparation and leveling of walls plays an important role in the long-term operation of plasterboard coating. The complexity of their preparation lies in the material from which they are made.

The most suitable and convenient option are the walls made of brickwork, which will only need to be coated with a primer.

If the walls are plastered, it is necessary to remove this coating, as it may fall off over time and deform the slab from the inside.

All other coatings, such as whitewash, old wallpaper, paint, also need to be removed.

The surface preparation process should be carried out in the following sequence:

• Tapping walls to identify weak spots and remove them.
• Removing the old coating.
• Plastering the resulting pits during the tapping process.
• Cleaning the surface from dust.
• Prime the walls with a deeply penetrating compound.
• Plasterboard sheets should also be primed.

A primer is necessary in order to preserve the finishing material from the appearance of mold, since primers have antibacterial properties that prevent the growth of fungus.

Solution and methods of its use

Gypsum is used as a fixing solution. As an option, you can use starting putty or alabaster, but to increase adhesion you need to add wallpaper glue or PVA to the solution.

How to apply the solution for different unevenness:

• If the difference in unevenness is 5 mm, the solution is applied to a sheet of drywall in a thin layer along the edges and in the center.
• With differences from 5 to 20 mm, a special adhesive composition is applied pointwise, in increments of 25 - 30 cm.
• If the differences reach 40 mm, then you first need to attach small pieces of plasterboard to the wall using glue, onto which, after the glue has dried, the main slabs will be attached.
• If it exceeds 40 mm, the method of frameless installation of finishing material is unacceptable.

Methods for frameless fastening of drywall

Sheathing walls with plasterboard without a frame is carried out in two ways, the choice of which is made based on the characteristics of the room being repaired.

There are several cladding options: gluing sheets to the wall and using self-tapping screws.

Gluing plasterboard sheets to the base of the walls

This is the easiest way to finish interior surfaces.

Gluing technology:

• First of all, you need to prepare wooden pegs for placing them under the sheets of drywall. They are necessary to obtain small gaps between the sheet and the floor (1 cm). Gaps must also be made between the sheets - no more than 0.5 cm.
• The adhesive is applied to the sheet in the manner that is most suitable.
• As quickly as possible, but very carefully, the material is glued to the wall.
• Using a level, the unevenness of the coating is adjusted by tapping problem areas with a rubber hammer.
• After tapping, you should again carefully check the entire surface for evenness before the solution hardens.
• After leveling the surface, the plasterboard board is supported with a wooden plank.

The alignment of the sheets must be done very carefully, since drywall is very fragile and can easily become deformed.

Once the finishing material is attached, the joints are covered with fiberglass mesh and puttied. The roughness resulting from the work is smoothed out with sandpaper. After cleaning the surface from dust, it is primed and covered with the chosen method.

Installation of drywall with self-tapping screws

This method is more practical than the previous one, but the installation technology is also a little more difficult. When applying this method, you need to add polyurethane foam and thick foam rubber to the base materials.

Fastening technology:

• Attaching the cut plasterboard sheets to the wall, drill holes in 10 places that will serve as a marker.
• After removing the slab, anchors are driven in at the marks.
• Pieces of foam rubber (10 cm from the holes) are glued to the plate, which will serve as a shock absorber.
• If there are sockets and switches on the wall, holes are immediately cut in the drywall for them.
• Leaning the sheet against the wall, fasten it using self-tapping screws.
• Leveling the surface is done by unscrewing or tightening screws.
• For high-quality fixation, holes with a diameter of 5 mm are made next to the screws, through which the mounting foam will be poured.
• After the sealant has hardened, the self-tapping screws are removed, and the holes after them are filled with putty.
• The final stage is gluing the seams and puttingty them, followed by sanding the surface.

Before pouring polyurethane foam, you need to first practice with the dosage. After the sealant comes out, you should get a spot no larger than 15 cm in diameter.

To summarize, we can say that installing drywall without a frame is a fairly acceptable way to level walls, which can be done by almost anyone without any special skills. To do this, it is necessary to correctly calculate and cut the material, as well as decide on the method of frameless fastening of drywall. If all requirements for the wall surface are met, the material will last a long time.
