What properties should the putty for the bathroom have?

First of all, let's see what the putty is? This is the finishing layer, which is applied before the final finishing to create a perfectly smooth and smooth surface. The main purpose of applying putty is to remove small defects and cracks. More serious irregularities should be previously corrected with plaster or plasterboard.

Regardless of what you will further trim the bathroom, the leveling layer should have the following characteristics:

• Water resistance. The bathroom is a room with high humidity. The coating should not break down or flake off under the influence of moisture even with the passage of time.
• Longevity. The service life of such a coating without loss of quality should be large.
• Resistance to temperature changes. Temperature differences should not lead to deformation of the puttying layer, otherwise - the lining on it will not hold.

These are the main criteria by which to choose the composition. All other characteristics depend on your individual needs and further cladding.

One of the main advantages of this type of mixture is high resistance to moisture. Therefore, they are recommended for use in the bathroom. The cost of such material is within reasonable limits, and the characteristics are quite high.

Important! Under the influence of moisture, the putty becomes even stronger. But this composition slowly dries and shrinks.

Polymer

At the moment, these are the most advanced developments, which, of course, affects the price. The surface is very smooth and smooth. Such putty is plastic and convenient in work, does not give shrinkage.

The putty on a polymer base can be of 2 kinds:

• Acrylic - is characterized by a high level of plasticization, so it can fill small irregularities and defects. The composition has no odor, has a high degree of adhesion to surfaces of wood or concrete.
• Latex composition - allows to obtain a mirror surface, not prone to cracking and shedding.

Gypsum

Gypsum compounds are not suitable for the bathroom, as they are unable to resist the concentration of hot steam, not to mention the possible leaks from the top.
