Varieties of decorative plaster for concrete
Decorative stucco for concrete is offered for sale in several varieties. These compositions are made of micro-concrete or microcement, which are composites and have gained popularity today among private builders due to interesting textures. The main advantage of the material is high adhesion with any base, whether it is metal, drywall, wood or concrete.
Plastering the facade of the house or internal walls can be carried out with microcement, which contains fine-grained cement and pigments, as well as modifying polymer additives. The small particle size determines the enhanced adhesion properties of the finished solution. The surface after hardening is not afraid of moisture, is not a suitable environment for the formation of mold, and also copes well with the effects of synthetic agents. Micro-concrete is made on the basis of the previous material, but among the ingredients you can also find an admixture of quartz. Due to this, the quality of wear resistance of the finished coating increases. The walls are able to undergo high loads, and it is impossible to scratch them.
Application technology
Decorative plaster for concrete should be applied in several stages, among them: surface preparation, soil application, mortar preparation, as well as plastering and creating relief. Sometimes there is a need to adjust the surface, and then paint the base and treat with glazing compositions.
Features of the preparation
If you decide to use the described composition for work, then you should ask how much the plaster costs and how to apply it. One of the first operations involves preparing walls from which it is necessary to wash off the dust, and if necessary, eliminate greasy stains, while using a solvent.
The concrete base is cleaned using special mechanical tools, for this you can put a brush on the drill for working with metal. If there is a grinder, then it is complemented by an grinding wheel made of sandpaper. In the presence of deep cracks, they need to be repaired with a solution of cement and sand, and small defects are ignored, since they can be filled at the stage of applying the main composition.
Before decorative plaster is applied to the walls, it is necessary to treat the surface with soil that penetrates deep inside, providing the maximum level of adhesion of the base surface to the finish. The primer reduces the level of water absorption, and before applying it, make sure that the plane does not have a high level of humidity.
Plastering
Next, you have to prepare a solution that is made from a dry mixture and liquid. With a mechanical method of processing walls, the consistency should be more fluid. Now the wizard can begin to manipulate. There may be several layers, but more often there are two. The first to fulfill the role of the base. In this case, the composition is poured with a trowel and distributed with a spatula over the treated area. It is important to maintain the required thickness of the finish in order to get an even plane.
Creation of a relief and its correction
Decorative plaster on the walls, as mentioned above, is applied in two layers. After the first has dried, you can proceed to the formation of the second. It is enough to leave the wall rough; for this, the plaster that is not completely dried should be wiped with a plastic trowel. If you want to get a deep texture, then you should use a steel trowel, with which the master will remove part of the material. The dried coating must be treated with fine grain sandpaper.
Final work
Imitation of concrete looks attractive not only inside, but also outside the house, however you can paint the walls treated with plaster, although this operation is not necessary. Most often, the surface is eventually painted not with a continuous layer, but with a screen pattern. Alternatively, you can paint it manually.
At the next stage, the walls are treated with a glazing compound. As the first option, you can use azure, which is a special varnish. Such a coating does not turn yellow over time under the influence of sunlight, and also does not deteriorate when steam acts on the walls. Instead of varnish, you can use decorative wax, which gives the surface an imitation of natural stone.
For reference
Concrete plaster may look like a rough finish. To do this, use 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 decisions. For example, high-tech style involves the use of concrete texture in conjunction with metal inclusions. Sometimes imitation of concrete is ennobled by Venetian plaster.
