Application of plaster

Properly applied plaster consists of layers. There are usually three of them – this is a spray, a primer and a coating. The thickness of the spray is from 5 to 10 mm. This layer reliably adheres to the surface of the wall and ceiling, providing excellent adhesion and reliably smoothing out all defects. The spray holds the weight of the next two layers – the primer and the top coat. Before spraying, the surface is slightly moistened with water, and the plaster mortar, as it were, is thrown onto the wall. By the way, now there is a new gasoline vibrating plate, which is already used by many people, it is not expensive.

After the spray has had time to “grab” and dry, a primer is applied to the surface. They fill all the cracks and irregularities of the first layer, so that the plane turns out to be even. Primer layer thickness approx. 80 mm. After the primer has dried and is ready to apply the third layer, a covering is placed on the wall, 2-3 mm thick. It finally levels the entire working plane and gives the plaster an even appearance.

Coating has a much more liquid consistency than spray and priming mortar. The smallest sand must be added to the composition of the coating solution. This composition helps prevent scratches on the plastered surface. The last stage of plastering work is for the master to grind the coating well in a circular motion. This work is not done with a spatula, but with a special construction tool (semi-terre). The surface becomes perfectly flat and ready for further finishing work.
