Acid concentration for cleaning old plasters and for removing sinterskin from new mineral plasters.
The sinterskin typical for lime based plasters is formed during drying of the plaster when the water used for preparation evaporates and the lime binders contained therein deposit on the plaster surface. This results in a high-tension, glass-like, brittle layer, in most cases of a characteristic shine. Sinterskin that is not removed may lead to flaking and stress cracks in the plaster. When using high-quality siciliate coating systems, the removal of sinterskin is especially important because it makes the plaster pores accessible for silicification. 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 at least a 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.
