The plaster walls in the bathroom under the tiles?

What plaster used for leveling walls in the

bathroom depends on from what material the walls are made and how they are processed. All plasters are divided into two major groups:

  1. plaster gypsum-based;
  2. Plasters Cement-based.

first can be used for interior decorating only and they are absolutely not suitable for the bathroom, because the plaster is very bad moves moisture.The second type is more versatile, it is not exposed to moisture, so it's perfect for the walls in the bathroom.

Depending on the material of the walls

specific kind of plaster that we choose will depend on thewall material.Consider the options.


professional master dressers often have to apply the plaster directly on the concrete surface, as it is - a very common material for the construction of houses. For concrete walls usually choose one of the two types of cement plaster:

  • traditional cement-lime;
  • more modern, polymer.

The last option is a conventional cement mortar with the addition of plasticizers, which make the mass more elastic.

For best results, before you begin plastering, concrete walls can be reinforced with special nets, made of metal or glass.

Brick Brick walls are quite undemanding, so they can grout through a variety of compositions. most frequently for finishing a brick to select one of the following types of plaster mixtures:

  • cement;
  • cement and lime;
  • sand and lime;
  • lime-plaster (this option in the bathroom it is better not to use it).

pour speed affects the quality of the finishing plaster mix.Gypsum plaster dries very quickly, so the work should be at an appropriate rate.Time Pour the lime plaster is much smaller, but they are much more plastic.

Partitions from plaster - it's not the best solution for the bathroom, as this material does not like high humidity.However, provided that the walls are made of modern, high-quality, water-resistant (!) Gipsoblokov, such an option can be considered quite acceptable.

For gipsoblokov exclusively to gypsum plasters as mortar on such a surface is simply not hold.In order to avoid the damaging effects of moisture on the surface of the plastered walls need to be sure to handle the special waterproofing compound, and only then to lay the lining.

How to plaster?

Plastering of walls in the bathroom takes place in several stages.

  1. preliminary surface preparation.Clear the walls from contamination and remnants of the old finishing materials.If the surface has large, visible stains, you should remove them.If the surface is perfectly smooth walls, add relief.To do this, we go through it a special notch - so the plaster will stick better.
  2. initial application layer.The first layer of plaster is called a scratch coat.At this stage, the plaster mixture should be diluted to a sufficiently fluid consistency that the solution can be applied in thin layers.First you need to moisten the wall using a paint roller or conventional spray.Then take a trowel and mix in small portions throw on the wall.This layer should be a relief, and we do not dub.
  3. Application of the base layer.The second layer of plaster is also called the rough.For him, we need a more dense solution, which we will apply with a trowel, and then dub a long metal trowel.The thickness of this layer should be about 0.5 cm.
  4. Applying the final coating.The last layer of plaster called finishing or finishing.It should be substantially thinner than the other, it must therefore be applied on a flat surface as possible.Before proceeding to final finishing, ensure that previous layers of plaster dry out well.Then again, moisten the wall and begin to apply the plaster immediately leveling section by section.Apply the solution may be a spatula, and dub in the same trowel, making a circular motion against the direction of clockwise.

Do I need additional waterproofing?

In conclusion, try to answer the question of interest to many young artists, dressers, "Should provide additional waterproofing wall in the bathroom?".The answer in most cases is no.
