BEECK ETCHING FLUID thoroughly removes sinterskin from new lime and lime based cement plasters and, thus, creates a silicification-active surface for subsequent treatment using BEECK silicate systems.

Appropriate for all mineral building materials of an at least partially calcareous character, especially plasters of the mortar categories PI-PIII acc. to DIN 18 550 indoors and outdoors. Also for cleaning weathered mineral plasters including old lime and silicate coatings. Unsuitable for gypsum or natural stone.
