Facade plaster solves several tasks at once: it levels the walls, protects the base from atmospheric influences and prepares the surface for decorative finishing or painting. At the same time, the durability of the coating depends not so much on the thickness of the layer as on compliance with the technology. Before starting repairs, owners often specify, upon request, the price of plastering the facade, which makes up the cost of such work. The total amount depends on the condition of the walls, the area and height of the building, the need for reinforcement and the type of finish chosen.
Preparation of the foundation
The facade must be carefully prepared before applying the mixture. Dirt, dust, peeling paint, fragile areas of old plaster and other materials that can impair the adhesion of the new layer to the surface are removed from the walls.
If you simply close the defects with a fresh compound without removing the weak base, over time the plaster may begin to peel off along with the old coating.
At the same stage, cracks and surface changes are assessed. Significant damage requires separate repairs before the start of the main plastering.
Why do I need priming?
After cleaning, the substrate is treated with a primer. Its task is to reduce and even out the absorbency of the surface and improve the adhesion of subsequent layers.
The primer is selected taking into account the wall material and the plaster system used. This step is especially important for porous or highly absorbent substrates.
Skipping priming is one of the common causes of premature cracking and peeling of the coating.
Applying plaster
If there are significant differences, the walls are aligned according to the lighthouses. This allows you to get the correct geometry of the facade and maintain the required layer thickness.
At PromAlp76ru facilities, plaster is applied in stages: first, the first layer is formed, then the next, after which the surface is leveled.
In areas with less rigid foundations, reinforcing mesh may be required. It is especially important in places where different materials meet, as well as for insulation, mounting foam and other bases prone to deformation.
Grout and finishing preparation
After applying the material, the surface is brought to the required condition using a grater or a half-grater. The quality of this stage depends on how evenly the paint or decorative layer will subsequently fall.
It is important to follow the correct grout technique. If pronounced tool marks remain on the surface, they may become even more noticeable after staining.
