Decorative plasters are one of the most recently used materials for finishing facades and exterior walls.

For this reason, the plaster itself must be:

- elastic - to retain its elasticity and not crack as a result of temperature changes;
- to have a high water repellency and at the same time to pass freely water vapor and carbon dioxide;
