Preparation of walls in the bathroom under the tile: in the panel house

Preparation of walls in the bathroom under the tile is a guarantee of successful work. If the walls are even, then laying the facing material will be much easier, and the glue consumption will decrease. However, not only the absence of vertical drops determines the success of these manipulations, but also the proper dismantling of the old cladding.

Removing old trim

Preparing the walls for the tiles in the bathroom should begin with the removal of the old coating, only after that you can begin to level the surface, and also cover it with compounds to improve the adhesion of materials. For example, the old tile must be removed together with the adhesive solution, and to facilitate the process, you need to clean the seams and soak the wall with water, leaving it in this state for several hours. If you will be preparing the walls for the tiles in the bathroom, the photo is recommended to be previewed, they are presented in the article.

Beginning to remove the old finish is necessary with an extreme tile, which is pierced by a chisel or with a hammer. The solution by this time will be softened, so removing the tiles will not be accompanied by difficulties. Moreover, the tile will remain intact, if this is fundamentally for you. When there is no need to preserve the old finish, it is possible to speed up the process by using an electric tool, which is equipped with a bit-shaped attachment. Whereas the remains of glue can be removed with the help of a Bulgarian.

Preparation of walls in the bathroom under the tile can provide for the removal of the paint layer, it should be disposed of with a grinding wheel, reaching the layer of plaster. If this is not possible, then the surface should be cut, this will improve the adhesion to the future coating. If the walls were whitewashed, in this case the lime layer must be disposed of, as the glue solution will not stick to such a surface. The base should be well washed, during which time it is possible to use a spray gun to soften the layer. Then a scraper enters the case. From the divorce you can get rid of rags. It is not suitable for tiling and decorative plaster, which is especially true for its relief variety. It can be knocked off the wall by hand or using an electric tool. From the wallpaper, whatever the material is, it is also necessary to get rid of them, they are soaked with water, and then removed with a scraper along with the glue. Leaving even the smallest particles of paper, you will reduce the strength of the adhesion of materials.

Aligning walls

Preparation of walls in the bathroom under the tile in the next stage provides for leveling. Perform these works in several ways, but the most common is the application of putty. Preliminarily, the wall is cleaned of dust, degreased and primed. After that, you should set up beacons and determine the amount of material required. If the differences are less than a centimeter, then one layer of putty will suffice, some masters do without it at all. If you are thinking about what kind of plaster to use, then you can prefer a cement-sand mortar or a ready mix, which is sold in the store. It is important to choose such a filler, which has a lower water absorption level. The finished mortar is applied to the wall with a spatula, and after that the layer is leveled, thus it is necessary to be guided by the beacons. Due to the fact that later you will lay the tile, there is no need to smooth out the composition, moreover, it will increase the quality of the clutch.

Recommendations for applying a mixture for leveling

Preparation of walls in the bathroom under the tile provides for several stages. If you need the leveling, then for this, as mentioned above, you can use plaster, which is applied to the primed wall, which eliminates the excessive absorption of water by the material. If there is an excessively smooth surface, it will be necessary to strengthen the plaster grid, which will prevent the solution from shedding. The application of the mixture must be accompanied by the use of a trowel, which must be moved from the bottom upwards, by typing small portions of the mixture on the working part of the instrument. At the final stage, it is necessary to use the level, but after the main layer has dried, grouting and grinding is carried out.

The final stage

After the plastered wall dries, it is covered with a layer of antiseptic, which will prevent the emergence and further development of mold and fungus. After all, they are the main problem in rooms with high humidity. As an additional protection will make a primer that will help increase the adhesion properties of surfaces and prevent excessive absorption of moisture from the solution. After its application, a protective film is formed on the wall, which increases the density of the wall. Continue further work on laying the finish coat can be after all the layers have dried.

Three steps to reduce the consumption of glue mixture

The preparation of walls for tiling in the bathroom can be done by a technique that will reduce the consumption of glue to a minimum. For this, the plaster will need to be applied in three stages. The first is called a spray and forms a layer, the thickness of which does not exceed 0.5 centimeters. This method is excellent for reinforced concrete panels and brick walls. If it is necessary to level the wooden wall, then the thickness of the spray should be 0.9 centimeters, but this includes a stuffed shingle or a metal mesh. The solution should have a consistency of liquid sour cream, it will be needed for rough alignment. Before the beginning of the work, the protruding elements are knocked off, the surface is dust-free, and the cavities are filled with a cement-sand mortar. This is important for depressions more than 5 millimeters. The purpose of the spray is to increase the adhesion to the subsequent layers.

Priming coat application

Alignment of the walls under the tile can be carried out until the base is not devoid of changes, then even a novice master can work on the work. Priming layer of plaster is applied two to three times, as the main task of these works is full leveling of the walls. The thickness of the intermediate layers should not be more than 5 millimeters, this applies to heavy cement mortars. If you are working with calcareous or gypsum compounds, the thickness should be 7 millimeters or less. The final thickness of the soil should not be more than 15 millimeters, all subsequent layers are applied after the previous ones dry out. It is important to align them.

Cover

The preparation of the walls in the bathroom under the tile in the panel house is completed with a covering, which is a finishing layer having a thickness of 2 millimeters or less. Work should begin when the previous lineup is not yet completely dry. If this happens, then the wall should be slightly moistened with water from the sprinkler.

Nuances of primer application

The preparation of the walls in the bathroom under the tile in a new building is no different from the technology used in old houses. After the completion of the above described step, it is possible to start applying the primer, while the air temperature should be in the range of -5 to +30 degrees. Humidity should not exceed 75%. In order not to use a stepladder, it is best to use a roller or brush with a telescopic handle, you need a tray for the soil itself. Mixing of the solution is best done with a mixer or drill, set at low speed. If there are no such tools at hand, you can mix the composition manually. A small amount of soil should be poured into the tray, and then a few brushes with a brush or roller. In this case, the liquid should not be sprayed on the sides.

When preparing the walls in the bathroom under the tile, the photo is recommended to be considered in advance, they will allow you to understand that applying the primer should not assume dry or excessively saturated areas. To hard-to-reach places can be reached with the help of a brush. After completion of the treatment, the wall should be left for 3 hours, during which time the soil will dry, and it will be possible to start applying the second layer.

Average priming consumption

Before you start preparing the walls for the tiles in the bathroom in Khrushchev, you need to ask what the consumption of the primer of different types. The numbers can vary, depending on the material in the base. If you want to apply on the plastered, brick or concrete surface primer of high penetration, then you need 1 kilogram of a dry mixture for 7 square meters of the base. The same amount of universal composition will be needed for 15 square meters, but the mixture on a water basis in the amount of one kilogram will be enough for 10 square meters. When the preparation of walls for tiles in the stalinka, then one kilogram of adhesive primer can be sufficient even for 3 square meters. Everything will depend on how intensively the substrate will absorb the mixture.
