Today, a variety of materials are used to level walls. Some prefer to use plaster solutions. Other owners of their own homes use drywall (photo finishes are presented in the article). Next, let's look at the nuances of work.
GCR advantages
Drywall is considered by many experts to be a universal coating. And this is quite understandable. With it, you can quickly and accurately align the corners of the walls. At the same time, not so much time will be spent on work. Another advantage of GKL is the ability to apply it on almost any surface. So, for example, drywall is often sewn onto wooden walls, brick and concrete surfaces.
Mounting Options
The most commonly used wireframe method. As elements of the crate, metal profiles or wooden bars are used. The disadvantage of this option is the reduction of the usable space of the room. However, between the supporting structure andsheathing can be laid heat and waterproofing. Leveling walls with drywall without a frame is used relatively infrequently. Meanwhile, this finishing option allows you to save space in the room. In addition, less time will be spent on work than in the case of a crate. However, leveling the walls with drywall without a frame has its drawbacks. In this case, it will not be possible to additionally insulate the room, 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, there is much less debris than in the case of preliminary arrangement of the crate.
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 subject to the negative effects of moisture and freezing. On the basis of normal importance, the installation of GKL is carried out on mixtures such as Fugenfüller or Perflix. Before gluing drywall to the wall, the concrete is treated with a special primer "Betonokontakt". This mixture will significantly improve surface adhesion. Bases that absorb moisture are treated with a Tiefengrund or Rikombigrunt primer. These compounds will prevent the adhesive from penetrating into the surface.
Select option
There are several ways to attach drywall to a wall without using a crate. Let's take a closer look:
• When the height difference is more than 4 mm, the sheets are fixed on the gypsum putty"Funenfüller". It is applied directly to drywall around the entire perimeter with a thin layer.
• At differences up to 20 mm, Perlfix mixture is used to fix sheets. It is applied in small piles at a distance of 30-35 cm.
• For unevenness up to 40 mm, plasterboard strips are first glued to the wall. Their width is 10 cm. Next, the sheets are already fixed on the Fugenfüller putty.
Progress of work
It should be remembered that, regardless of how the walls will be leveled with drywall - without a frame or with it, the work is carried out before laying the flooring. GKL should be mounted indoors at a temperature not lower than 10 degrees. Before fixing, the sheets should be kept in the room for at least 2-3 days. Simple drywall is suitable for rooms with moderate humidity and constant temperature conditions. For places such as a bathroom, a corridor, a kitchen, moisture-resistant sheets are used. They differ from the usual green surface color.
Preparation
Before you attach drywall to the wall, you should assess the condition of the base. To do this, you need to use a plumb line and level. Depending on the condition of the surface, one of the installation methods described above is selected. Markings are made on the ceiling and walls with a plumb line. If the base is damp, 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 sticking drywall to the wall, the sheets should be tried on and cut. In this case, you should immediately mark the holes for switches and sockets. There should be a gap of 8-12 mm below. During attachment, if gaps remain, they can be sealed with silicone.
Laying sheets with 4 mm differences
Gypsum putty is applied to the wall along the marked perimeter using a notched trowel. For greater reliability, 1-2 vertical stripes are also made in the center of the rectangle. Next, plasterboard linings are installed around the entire perimeter of the walls. The bottom of the sheet is fixed to the strip. Then, using a level, lightly tapping with a rubber mallet, the drywall is put in place. Many try to drown the sheet deeper, assuming the likelihood of a bump further on the surface. However, experts do not recommend doing so. Better spare no glue and apply more.
Installation of sheets with differences of 4-20 mm
In this case, a more reliable Perlfix mixture is used. Glue is applied in heaps. They can be made with a craftsman. 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.
Fixation of sheets with differences of 4 cm
In this case, experts recommend not saving not only on glue, but also on the drywall itself. As mentioned above, firststripes are fixed. They are glued at a distance of not 60, as it is customary to mount the profile, but 40 cm. In this case, the whole 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. Be very careful when tapping drywall.
Alternative
This method involves the use of mounting foam instead of adhesive. In addition to it, you will need a drill, wooden plugs and screws with washers (self-tapping screws), foam rubber (thick pieces) to work. As in the previous version, the condition of the surface is preliminarily assessed and all necessary preparatory work is carried out.
Fixing GKL on mounting foam
A drywall sheet is applied to the wall. In 8-10 sections, holes are drilled to the base. The points should be distributed as evenly as possible. Next, the sheet is removed, and holes are made in the marks made on the wall and wooden plugs are hammered into them. You can also 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 self-tapping screws (screws with washers). The regulation of drywall to take it to the desired position is carried out by loosening or tightening the fasteners. This operation is carried out with allsheets. After they are fixed on the base, you should use an electric drill to make holes near all the screws. Their diameter is 5-7 mm, and the depth is 2-3 cm. Mounting foam will be pumped into these holes. Before filling, it is recommended to try with the 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 cylinder. If there are sockets or switches, holes for them are cut out in drywall before fastening.
Advantages and disadvantages of foam fixation
First of all, it must be said that this method of attaching drywall to the wall is used when there is not much time for installation. At the same time, the work should be carried out as efficiently as possible. The disadvantage of this method is the inability to place heavy and bulky items on the wall.
