Today, a variety of materials are used to align the walls. Some prefer to use plaster mortars. Other owners of their own homes use drywall (photo finishes are presented in the article). Next, we will understand the nuances of work.
Advantages of GCR
Drywall is considered by many experts as a universal coating. And this is understandable. With its help, you can quickly and accurately align the corners of the walls. At the same time, not so much will be spent on work. Another advantage of GCR is the ability to apply it on almost any surface. So, for example, plasterboard is often sewn onto wooden walls, brick and concrete surfaces.
Mounting options
The most commonly used wireframe method. As elements of the lathing, metal profiles or wooden bars are used. The disadvantage of this option is to reduce the usable space of the room. However, in this case, heat and water insulation can be laid between the supporting structure and the casing. Aligning walls with drywall without a frame is used relatively infrequently. Meanwhile, this finishing option saves space in the room. In addition, less time will be spent on work than in the case of the crate. However, leveling the walls with drywall without a frame also has disadvantages. In this case, the room cannot be additionally insulated, since there simply will not be room for laying insulation. However, such a frameless method of fixation takes place without noise and dust. After work, the debris is much less than in the case of preliminary arrangement of the crate.
The first stage of work
Before you start leveling the walls with drywall without a frame, you need to prepare the surface. It should not be exposed to the negative effects of moisture and freezing. On the basis of normal importance, the installation of gypsum plaster is carried out on such mixtures as Fugenfüller or Perflix. Before gluing drywall to the wall, concrete is treated with a special primer "Concrete Contact". This mixture will significantly improve surface adhesion. Moisture-absorbing substrates are treated with Tifengrund or Rikombigrunt. These compositions will prevent the penetration of glue into the surface.
Option selection
There are several ways to attach drywall to a wall without using a crate. Consider in more detail:
• For height differences of more than 4 mm, the sheets are fixed on the gypsum putty "Funenfüller". It is applied directly to drywall along the entire perimeter with a thin layer.
• For differences up to 20 mm, Perlfix mix is used to fix the sheets. It is applied in small piles at a distance of 30-35 cm.
• For irregularities up to 40 mm, strips of drywall are first glued to the wall. Their width is 10 cm. Next, the sheets on the Fugenfüller putty are already fixed .
Working process
It should be remembered that, regardless of how the walls will be aligned with drywall - without a frame or with it, work is carried out before the flooring is laid. GCR should be mounted indoors at a temperature of at least 10 degrees. Before fastening, sheets should be held in the room for at least 2-3 days. Plasterboard is suitable for rooms with moderate humidity and constant temperature. For places such as a bathroom, a corridor, a kitchen, moisture-proof sheets are used. They differ from the usual green surface.
Training
Before attaching drywall to the wall, the condition of the base should be assessed. To do this, use a plumb line and level. Depending on the surface condition, one of the installation methods described above is selected. Marking is made on the ceiling and walls using a plumb line. If the base is moist, it must be thoroughly dried, remove all protruding elements and dirt. The surface should also be degreased. Next, the base is covered with a primer.
Important points
Before gluing drywall to the wall, the sheets should be tried on and cut. In this case, you should immediately note the holes for the switches and sockets. A gap of 8-12 mm should remain below. During fastening, if gaps remain, they can be repaired with silicone.
Laying sheets with differences of 4 mm
Using a notched trowel, plaster putty is applied to the wall along the marked perimeter. For greater reliability, 1-2 vertical stripes are also made in the center of the rectangle. Next, plasterboard linings are installed around the perimeter of the walls. The bottom of the sheet is fixed to the strip. Then, using the level, easily tapping with a rubber mallet, drywall is put in place. Many try to drown the sheet deeper, suggesting the likelihood of a hillock appearing further on the surface. However, experts do not recommend doing this. It is better not to regret the glue and apply it more.
Installation of sheets with differences of 4-20 mm
In this case, a more reliable mixture of Perlfix is used. Glue is applied in heaps. They can be made a trowel. The diameter of the heaps should be approximately the same. Their height is no more than 25-30 mm. Further actions are the same as in the previous case. Be sure to install lining around the perimeter. Sheets are fixed on them.
Fixing sheets with differences of 4 cm
In this case, experts recommend not saving not only on glue, but also on drywall itself. As mentioned above, the bands are fixed first. They are glued at a distance of not 60, as is customary to mount a profile, but 40 cm. In this case, the entire structure will become more reliable. After the strips are glued, you need to let them dry for 2-3 days. Then, using putty, the sheets are fixed to this frame. When working, you should also use a level and a rubber mallet. Tap on drywall should be very careful.
Alternative option
This method involves the use of mounting foam instead of adhesive. In addition to it, you will need a drill, wooden corks and screws with washers (self-tapping screws), foam rubber (thick pieces) to work. As in the previous version, the surface condition is preliminarily evaluated and all necessary preparatory work is carried out.
Fixing GKL on polyurethane foam
A sheet of drywall is applied to the wall. In 8-10 sections, holes are drilled to the base. Points should be distributed as evenly as possible. Next, the sheet is removed, and holes are made in the marks on the wall and wooden corks are hammered into them. You can use plastic inserts. Foam rubber is glued onto a drywall sheet at a distance of 10-12 cm from the holes. During installation, it will serve as a control spring. Next, the sheet is again applied to the wall and fixed with screws (screws with washers). Drywall regulation for the adoption of the necessary position by loosening or tightening the fasteners. This operation is carried out with all sheets. After they are fixed on the base, holes should be made with an electric drill near all the screws. Their diameter is 5-7 mm and the depth is 2-3 cm. Foam will be pumped into these holes . Before filling, it is recommended to try with a dosage in any area. As a result, it is desirable to ensure that the foam forms a spot of 10-15 cm when leaving the container. If there are sockets or switches, the holes for them are cut out in drywall before fixing begins.
Advantages and Disadvantages of Foam Fixing
First of all, I must say that this method of attaching drywall to the wall is used when there is not much time for installation. At the same time, work should be carried out as qualitatively as possible. The disadvantage of this method is the inability to place heavy and dimensional objects on the wall.
