Application

In the interior, especially in ecological-biological building construction and preservation of historic monuments. On masonry of all types, concrete and plaster supports. May be used on all suitable substrates in one or several layers. Excellently suitable as priming plaster for our CAREMA® lime-clay fine plaster (2-layer plastering system for the interior).

Plaster substrate

The plaster substrate must be dry, clean and free from loosely attached particles. Always carry out plaster substrate test according to VOB/C and DIN 18350. Smooth substrates and concrete surfaces must be pretreated with CALCEA® lime bonding plaster. Any surfaces not suitable as plaster substrates must be spanned with plaster supports. Wet well strongly absorbing substrates in relation to their absorbencies.

Processing

Process with all commonly used plaster machines or by hand. After absorption, sharply level with metal straight edge or smooth with grated scraper. In case of plaster thickness of > 15 mm, it is compulsory to apply several plaster layers with a sufficient waiting period.
