There are several ways to enhance the aesthetics of a building. One of the ways to achieve this is by adding plaster to the walls or ceiling. It provides smoothness to the surface and also protects the wall from any kind of damage. A professional plasterer will spread the wet plaster over the bricks and then use the right equipment to smoothen the surface. It creates a seamless surface for painting.
The wet plaster that is spread on the surface should not be more than 0.3 cm. But in case the base surface is uneven, then the thickness of the plastering layer should be more than .3cm. If the walls are made of different sized stones, then the plasterer will increase the number of coats.
Also, the plasterer will ensure that the first layer completely dries out before applying the second coat, as the wet surface may sag, and if not dried properly, the final coat will not be smooth.
