How to properly align the walls in the bathroom

Walls and straight angles that are not buried vertically are a rare phenomenon. Therefore, when repairing the issue of how to level the walls in the bathroom, occurs with an enviable periodicity.

Aligning the walls with putty

If the surface is too uneven, putty put on the layer of plaster.

Basic methods

There are several methods, the use of which will make it possible to obtain smooth surfaces ready for subsequent finishing.

Aligning the walls with a cement-sand mortar is the application of a layer of plaster. By adjusting the thickness of the applied solution, the deviations of the walls from the vertical can be leveled.

The merits of this method include:

  • obtaining an even solid surface with no internal voids;
  • insignificant thickness of the plaster layer, which is very important for a bathroom of a small area.

Among the shortcomings can be noted the following:

  • the presence of wet, dirty work on the preparation and application of the solution;
  • the need for surface preparation work prior to application of the leveling layer;
  • The presence of a technological break required for solidification of the solution;
  • sufficiently large physical laboriousness of work.

Aligning the walls with plasterboard will help to avoid the negative moments inherent in plaster. The work can be carried out without preliminary preparation, and the resulting surface will be almost immediately ready for further finishing.

The main drawback of gypsum plasterboard is the presence of internal cavities in the wall. The bathroom is extremely humid, and if the waterproofing is poorly done, moisture can get inside with all the consequences: mold and fungus development and gradual destruction of wall materials.

Determination of roots of walls

The smoothness of the walls is determined with the help of a building level.

Also, unlike the previous method, the frame already eats a sufficiently appreciable area of ​​the room.

Tools and materials

Before you begin to level the walls, you need to determine the degree of their deviation from the vertical. For this it is simpler and more convenient to use a two-meter building level.

When leveling by plastering surfaces, you will need:

The scheme of installation of beacons for leveling

The scheme of installation of beacons for alignment.

  • cement and sand for the preparation of mortar or ready-made plaster mixture;
  • primer - allows to give the surface more adhesion to the applied coating;
  • reinforcing mesh;
  • beacons - their use allows you to get a smooth surface of the wall;
  • gypsum or alabaster solution for attaching beacons.

From the tools for making mortar and applying it on the walls you will need:

  • a drill with a nozzle-mixer;
  • solution capacity;
  • rule;
  • wide spatula.

Work with plasterboard, except for the material itself, will require the use of:

  • metal profiles;
  • Dowels for fixing profiles to the base of the wall;
  • moisture resistant filler and tape serpyanki for sealing joints sheets.

You may need a perforator, a screwdriver and metal scissors.

Alignment with plaster

Alignment of walls with plaster mortar first of all begins with the preparation of the surface. To do this, remove all old coatings (paint, plaster, tile). Here it is necessary to observe the principle of reasonable sufficiency: if the coating is firmly adhered to the substrate and does not interfere with the application of an additional leveling layer, then it can be left.

The surface of the wall is covered with a coat of primer.

If its adhesion capacity is not sufficient, an reinforcing mesh is additionally attached.

The procedure for repairing the plaster layer at the corners

With the help of a level and a plumb on the surface of the walls guide rails are placed. Later they will help to get a flat vertical surface.

Fastening beacons is carried out with the help of small pieces of gypsum or alabaster solution. The mortar is applied evenly throughout the entire height of the wall with small portions. A beacon is pressed into it.

Vertical position and uniformity of indentation in the fastening solution are controlled by level or plumb. The supporting edges of all installed elements must be in the same line.

Then the plaster solution is prepared and a wide spatula or trowel is applied to the wall. The rule, relying on the beacons, evenly distributes excess solutions throughout the wall surface. After leveling the walls, it is necessary to withstand a technological pause. During this time, the plaster layer will completely harden, and you can start finishing work.

Application of plasterboard

If the decision is made to level the walls with plasterboard, then the total cleaning of the wall surface can not be carried out. The degree of surface adhesion in this case will not play a role. In fact, there will be an additional gypsum plasterboard wall.

The fixing of plasterboard sheets to the wall is carried out mechanically through a pre-assembled frame. The profiles, which form the basis of the gypsum board structure, are fixed to the wall surface with the help of dowels. The verticality and correctness of the mutual position of the profiles are also controlled by the building level.

Before proceeding to the finish, it is necessary to carefully fill all the joints of the sheets and the places of their joining to the floor and ceiling. To do this, the tape is used for serpent and moisture resistant putty.

In cases where the deviation of walls from the vertical is insignificant, it is possible to fix the gypsum board with small portions of glue solution. The adhesive is applied to the surface of the sheet with small knots in small piles. The sheet is tightly pressed against the wall and then, with the aid of a level, is exposed in a vertical plane.


Sometimes the walls of the bathroom are straightened out directly with the tiling of the surface. However, remember that this is not always effective. Of course, if the differences are 0.5-0.7 cm, then it will be possible to equalize. And if more? For example, 5 cm? The tile will simply fall off, and all your efforts will go to nothing.

Basically, the errors are concealed by applying a sufficiently thick layer of tile adhesive. Each tile is applied and leveled in place. In this case, both the vertical alignment as a whole and the location of the already glued tiles are aligned.

Such a method makes it possible to exclude a number of laborious works on preliminary plastering or the erection of a frame wall, but it requires considerable time and experience in carrying out similar work.

Each method has its own merits and advantages. The expediency of applying this or that method should be determined on the basis of the specific conditions and experience of the master who conducts the work.
