Substrate preparation
The substrate must be dry, load-bearing, free from grease residues, adhesives, cement milk, and other contaminants that could impair the adhesion of the product to the substrate. Old paint, epoxy, tar, and asphalt layers must be removed. Plywood panels must be free from paraffin residues, roughened, and cleaned with soapy water. New and old (repaired) concrete must be cured and matured. The substrate must not be frozen or covered with frost, and there must be no water pockets. Damaged or cracked substrates must be repaired. BEKATEQ Quarzgrund is not intended for substrate consolidation. If the substrate is absorbent and must first be consolidated, it must be pre-treated with the BEKATEQ BE-518 primer. In this case, wait for the primer to dry, then apply the quartz primer using a roller or brush.
