Using plasterboard, you can level almost any wall. For small irregularities or in a small room, it is better to attach the sheets using glue.
Plasterboard walls will help hide unevennessor existing communications. Frameless installation will allow you to save space significantly and simplify the work of wall cladding. However, depending on the degree of curvature of the walls, different gluing methods are used. It may happen that in one room you will have to combine installation methods.
Surface preparation, necessary materials and tools
One of the advantages of frameless installation is the absence of a preparatory stage as such. Minimal processing is required beforehand.
Tools for finishing walls with plasterboard.
With the use of a plumb or rule, the baseMeasure and determine whether it is curved or deflected from the vertical. This is necessary in order to determine which of the methods of gluing will be optimal.
From the surface you need to remove all the protruding elements: nails, screws, dowels, etc.
Walls should be cleaned of dust and grease stains and markings should be made.
On the floor, draw lines along which the finishing material will be leveled. With significant unevenness it will be necessary to do the same on the ceiling. This will allow you to set the sheets in the same plane.
If the surfaces have poor adhesion, thentreat them with a primer that enhances this quality. If the walls absorb moisture very much, then a tool that reduces this property should be used. Also, when choosing a primer, you need to take into account the material of the walls.
Once the walls are prepared, you can begin work. For this you will need:
- spatulas;
- drywall;
- glue or gypsum plaster;
- container for solution guidance;
- plumb bob;
- knife;
- 2 or 3 wooden blocks;
- pencil;
- sealant;
- reinforcing tape.

What else you need to know before you glue the drywall; preparation of sheets
Scheme of frameless method of finishing walls with plasterboard.
Frameless method can be used only in cases where the size of the walls does not exceed the dimensions of the sheet. Substituting small pieces is not desirable.
Do not glue GCL on lime plaster.
All work with the wiring must be completed before gluing the GCR.
Glue sheets can only be on the supporting base. It should not crumble or exfoliate. For more reliable bonding to the surface, you can use 4-5 anchors per plate.
Do not use gypsum board if it is exposed to weathering (snow, rain, etc.).
Work can be carried out at room temperature + 10 ° C.
Plates should stay in the room in which they will be glued for 2-3 days.
It is necessary to cut out the GCR in such a way that up toThere was a small gap (approximately 10 mm). It is necessary in order to exclude the contact of plasterboard with the floor from which the sheet can receive moisture.
It is easiest to work with gypsum board if the unevenness of the base does not exceed 4 mm. The sequence of actions is as follows:
Scheme of leveling walls using plasterboard.
Usually the decoration of the walls starts from the corner.
The solution is made according to the instructions.manufacturer. You should not prepare a large amount at once, since its shelf life is usually short. Most often, Fugenfüller is used for these purposes.
On the perimeter sheets a notched trowel is appliedsolution. They also carry 1 or 2 bands in the center. If it is planned to hang shelves and other furniture, the sizing should be continuous. However, putty should not go to the junction.
Along the wall are installed pads (2-3 pieceson the sheet), which will ensure the preservation of a gap of 10 mm. The support must provide ventilation, since air needs to dry out. As linings, you can use gypsum board trimming.
The plate rises and mounts on the supports, then presses against the wall. It will be more convenient to take the finishing material, if it is put on a small flooring of wooden bars (2-3 is enough).
With the help of a fist or a rubber kiyanka, the sheet is aligned vertically. As a guide, lines drawn on the floor are used.
In this order, the entire room is trimmed around the perimeter. Using the rule, the smoothness of the GCR setting relative to each other is checked. Seams should be smooth and dense.
In gypsum cardboard, it is necessary to provide openings for communications, sockets and switches. Cutting is best done locally.
After 3-4 days, after the glue dries, the supports are removed, and the gaps are sealed with sealant.
When a tree is allowed to use nails with wide hats. The glue here will be used more for alignment.

If the unevenness of the walls varies from 5 to 20 mm
In this case, it is practically no different from the first method: the sequence of actions remains the same, only the glue and the method of its application are replaced.
For large uneven surfaces, use"Perlfix". This glue is applied to the sheet in small piles. Their diameter is 100-150 mm, and the height should be slightly larger than the depth of the depressions (from 100 to 300 mm). These cakes are planted quite often: every 300-350 mm, first along the perimeter, and then in the central part.
Then the sheet is lifted and installed on the substrates. It is also aligned vertically (for this purpose lines drawn on the floor and ceiling serve).
When the glue leaves the joints, it is removed with a spatula. The solution in the seam should not be.

What to do if the roughness is 20-40 mm
The most difficult thing is to finish walls with plasterboard if there are large depressions or bumps.
Scheme of wall covering with plasterboard on a metal frame. In this case, fastening by "beacons" is used.
From the plasterboard you need to cut strips 10 cm wide andglued to the wall vertically. They need to be fastened every 40 or 60 cm. The more frequent the step, the more reliable the fastening. For this, it is better to use the glue "Perlfix".
The bands are aligned so that they are inone plane. Thus, it turns out a kind of skeleton from the GKL. Aligning the walls with gypsum boards occurs exactly at the stage of attaching the base. The glue will be applied in groups, but the height will be different for everyone: somewhere 10 mm, and somewhere 30 mm or more.
When a frame is assembled on all walls (or places with large gaps), it is left to dry.
After 2-3 days, gluing is done.plasterboard. It is attached using "Fugenfüller". Some people prefer liquid nails. Both methods provide high-quality adhesion between the frame and the plasterboard.

Completion of work
The glue under the drywall must dry.This takes 2-3 days. Then you can proceed to the final stage: filling the joints. First, a leveling layer of mortar is applied, then reinforcing tape is pressed into it. After drying, a second layer is applied - leveling. Also, if screws or nails were used somewhere, they also need to be covered. To do this, the heads are sunk into the finishing material. You can use the same filler as for gluing. Gaps along the floor are sealed with sealant. It is possible to use different methods even within one wall. When the joints are dry, you can proceed to the final finishing of the room.
