ApplicationIn the interior and exterior, in particular in biological, ecological building as well as cultural heritage protection. 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 CALCEA® fine lime plaster, CAREMA® lime-clay fine plaster and CALCEA® fine lime coat as well as all mineral finish plasters. If CALCEA® lime priming plaster shall be used in exterior areas, please contact our technical consultants.
Plaster substrateThe 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 pre-treated with a suitable bonding bridge. Any surfaces not suitable as plaster substrates must be spanned with plaster supports. If a bonding improvement or regulating of the absorbency of the substrate will be required, a net-shaped or full-surface preliminary splatter-dash with CALCEA® lime bonding plaster must be applied.
ProcessingProcess with all commonly used plaster machines or by hand. After absorption, sharply level with metal straight edge or smooth with grated scraper. Waiting period before further coating: per 1 mm layer thickness 1 day at suitable drying conditions. In case of plaster thickness of > 15 mm, it is compulsory to apply several plaster layers with a sufficient waiting period.
Special notesProtect fresh plaster against fast drying-up. The air and surface temperature must be at least 5 ° C and maximum 25 ° C. CALCEA® lime priming plaster shall only be used in the original state without additives.
StorageDry, if possible on wooden shelves and protected against draft.
