Plaster that is excessively liquid, or thick, does not set properly and may come loose from the surface as it dries.
Since cement plasters cannot be tinted or thinned with paint, facade paint must be applied separately to the plaster after it has dried.

- high price.
Silicate

- environmental friendliness;
- strength;
- resistance to temperature changes;
- good thermal insulation;
- can be applied to any material without additional reinforcing elements.
- high price;
- very fast drying, working with it requires speed and skill;

Bark beetle
A highly coveted and widely used texture is the bark beetle texture.
It is created by the inclusion of various fractions of minerals and resembles wood that has been eaten by a beetle. The size of the cracks will increase with the fraction of pebbles.
After applying the plaster to the prepared base, the composition must be allowed to set for a while; otherwise, you can scrape off the entire layer of plaster rather than creating decorative cracks. After that, the surface is rubbed with a trowel based on personal preference. can be randomly rubbed in a circular motion in both vertical and horizontal directions.
Fur coat
Lamb is another name for it. The addition of tiny (between 1 and 3 mm) pebbles to the composition produces the volume effect. The fur coat can be made by machine or by hand, pressing and removing the fur against wet plaster with a trowel or roller.
