Quite often, home craftsmen andprofessional builders resort to the solution of leveling walls using plasterboard. The material can be installed on the surface in two ways, the first of which involves the use of a lathing system, and the second - glue. In the latter case, the master faces the question of how to glue plasterboard to the wall. They try to refuse the first method of carrying out work, especially if the room where the walls are leveled has limited space, because after installing the frame system, the room will have an even more cramped area.
Drywall is used to level walls in rooms.
Preparatory work
Before gluing drywall to the wall,you should check how even the surface is. The permissible deviation is 2 cm, otherwise it will not be possible to fix the gypsum board. The surfaces that are supposed to be leveled with gypsum board should not freeze. This is due to the fact that additional use of insulation is allowed only by a system based on a hollow space under the frame. Concrete panels will be an excellent base for gluing the material. This is true, even if their installation was not carried out very vertically, the main plane of the plate has a sufficient degree of evenness.
Methods of applying glue to plasterboard.You can glue plasterboard using Knauf brand compounds, which were specially developed for covering surfaces with this material without using a frame. To carry out the work, you need to prepare some materials and tools:
- glue;
- drywall;
- level;
- roulette;
- knife;
- a primer;
- sealant;
- notched trowel.

Features of the work on gluing GKL on smooth walls
Analyze how even thethe wall, you can use a long level, a rule or a stretched cord. As a composition for fixing the material, you can use gypsum putty made on the basis of glue. Initially, the walls should be cleaned of dirt, dust, and greasy stains. The surface should be dry, if necessary, you can use a heat gun for drying. After the wall, it is necessary to prime it, this will reduce the surface's ability to absorb moisture and will guarantee more impressive adhesion.
Knauf glue is made specifically for gluingplasterboard on the walls. If necessary, wiring is carried out along the wall. Electric power cables should be buried in pre-prepared grooves. Before gluing the plasterboard to the base, the material should be cut, while the height of the sheets should be such that after installing the sheets, about 10-15 mm remains to the floor surface. First, holes should be prepared in the sheets for installing switches and sockets. In order to avoid errors in complex areas, it is preferable to trim during installation. After that, you can begin to apply the adhesive mixture to the surface of the plasterboard sheet. To do this, a strip of putty 12-15 cm wide should be applied along the entire perimeter of the sheet using a notched trowel. Using the same technology, about two strips should be placed in the center of the sheet. If the work uses a sheet with a thickness of 12.5 mm, then one strip located in the center will be enough, whereas when using a thinner sheet, there should be two strips.
Scheme of puttying plasterboard joints.Often the surface of the walls is then finished with tiles, which means that this part of the base will be subject to additional load. At the same time, when installing the sheets, the adhesive composition must be applied to the entire surface. For example, a shelf or a cabinet that is supposed to be hung on the wall can act as a significant load. The application of glue should be done very carefully, as this can cause the sheet to break. In order to avoid this, it is recommended to place a frame of bars near the gluing point and under it. At the next stage, you can start gluing the drywall to the wall. In this case, the sheet must be lifted, placed on pads and pressed well against the wall along the entire base. Now you can use the level, which will allow you to determine the protruding areas. They can be eliminated by gradually pressing. In addition, the evenness of the base must be checked vertically. After you have completely managed to glue the drywall to the walls, you should leave the surface until the composition has completely dried. Only then can you start processing the joints with a putty compound, which can be replaced with a sealant. Before carrying out the work, it is preferable to enlist the help of a second master, this will facilitate the process and speed up its completion. This is also true because it can be quite problematic to cope with a sheet weighing 30 kg on your own. Return to contents</a>
GKL gluing technology to uneven walls
Essential tool for working withplasterboard. The wall that has some unevenness can still be used for gluing plasterboard. The principle of the work will be to apply the composition to the plasterboard sheet pointwise. Such work can be carried out with walls whose difference in level does not exceed 2 cm. For this, you can use the Knauf brand composition, represented by the Perlfix dry mix. When gluing plasterboard to the wall using this technology, you must follow the following instructions. Initially, you will need to make markings, this will allow you to strengthen the material in one plane during installation. To do this, a straight line should be drawn on the surface of the floor and ceiling with some indentation from the wall. To mark, use a plumb line and a tracer, the latter of which is a thread with dye applied. These marks will serve as a guide when installing the sheets. You can glue plasterboard to the walls using gypsum glue, which should be applied with a trowel. The composition must be laid in small mounds along the entire perimeter of the sheet, the distance between them should be about 20-25 cm. On the remaining part of the sheet, you will also need to lay out mounds of glue, but in this case the step should be increased to 30-40 cm. After that, the sheet must be carefully lifted and applied to the wall surface, aligning it with the reference points. After the composition dries, you can begin to seal the seams between the sheets. Gluing drywall to the walls can be done if they have a flat surface or minor irregularities. In this case, the process will be much cheaper and less labor-intensive, compared to the one that involves preliminary installation of the frame system. In addition, only a professional craftsman can install the frame. After gluing the material to the walls of the room, you can begin finishing work, and if alignment using this technology is supposed to be carried out in the space of the bathroom, then you need to purchase a water-repellent material that has a green color.
