The plaster of the facade of the house or internal walls can be carried out with a micro cement that contains fine cement and pigments, as well as modifying polymer additives. An insignificant particle size determines the enhanced adhesion properties of the finished solution.

Features of training

The concrete base is cleaned with special mechanical tools, for this purpose a brush can be put on the drill to work with metal. If there is a Bulgarian, then it is supplemented by a grinding wheel made of sandpaper. In the presence of deep cracks, they must be sealed with a solution of cement and sand, and small defects are ignored, as they can be filled at the stage of application of the basic composition.

Before decorative plaster is applied to the walls, it is necessary to treat the surface with a soil that penetrates deeply, ensuring maximum adhesion of the base surface to the finish. The primer reduces the water absorption level, and before applying it, make sure that the plane does not have an elevated humidity level.

Application of plaster

Further it is necessary to prepare a solution, which is carried out from a dry mixture and a liquid. With a mechanical method of wall treatment, the consistency should be more liquid. Now the master can start manipulating. There can be several layers, but more often there are two. First perform the role of the base. In this case, the composition is thrown by the trowel and distributed by a spatula over the treated area. It is important to maintain the required thickness of the finish, in order to obtain an even plane.

Creating a relief and correcting it

Decorative plaster on the walls, as mentioned above, is applied in two layers. After drying the first one, you can proceed with the formation of the second one. It is enough to leave the wall rough, for this not completely dried plaster should be wiped with a plastic trowel. If you want to get a deep invoice, you should use a steel trowel, with which the wizard will delete some of the material. Dry the coating should be treated with sandpaper with fine grain.

Final work

Imitation of concrete looks attractive not only inside, but also outside the house, but you can paint walls treated with plaster, although this operation is not mandatory. Most often, the surface is eventually stained not with a continuous layer, but with a stencil pattern. As an alternative, you can manually write it.

This coating does not turn yellow with sunlight and does not deteriorate when steam is applied to the walls. Instead of varnish, you can use decorative wax, which gives the surface an imitation of natural stone.

Concrete stucco may look like a rough finish. To do this, use a synthetic liquid wax, which has excellent protective properties and guarantees a light matte shine. In general, the decorative effect should be selected depending on the interior solutions.
