Quick drying Easy to apply WEP 180 Tutorial-Clip Application range primer under STAUF PU-, SPU- and SMP-adhesives primer under STAUF levelling compounds sprinkled with sand after first coat before levelling with STAUF levelling compound (with STAUF VDP 160 as a primer) vapour barrier on cement screeds containing residual moisture up to 4.0 CM%. Suitable subfloors mastic asphalt screed concrete C 25 / 30 according to DIN 1045 (non-skid surface) calcium sulphate (flow) floors (no moisture barrier) wooden planks, wood fibre boards chipboards (P4 to P7), OSB boards (OSB/2 to OSB/4) stone, ceramic, terrazzo, tiles unlaminated gypsum fibre boards cement floors cement floors with residual moisture Product properties good adhesion to various materials very economical very low emission can be diluted with water reduction of the vapour diffusion rate on sufaces with residual moisture Hardener: yellowi

^ First coat: approx. 150 - 200 g if applied with a roller (diluted 1:1 with water) ^ Second or further coats as a vapour barrier: approx. 200 g undiluted if applied with a roller ^ thin coat application, undiluted, as a bonding agent on nonabsorbent surfaces: approx. 100 g/m2 if applied with a roller ^ the quantity required increases significantly if the substrate is highly porous Drying time ^ 1. Coat diluted with water (1:1): approx. 2 hours ^ 2. Coat undiluted or further coats applied as a vapour barrier: at Additional instructions 1 ^ If levelling layers thicker as 10 mm are to be applied,...

SUBFLOOR PREPARATION It must be ensured that the subfloor is ready for installation by performing proper subfloor preparation, floors must be clean, have sufficient surface strength, must be level, permanently dry and free of cracks. A mechanical pretreatment of the subfloor (sweeping, vacuuming, mechanical brushing, sanding, milling, shot blasting) must be performed depending on type and condition of subfloor. Cracks and joints, except expansion joints and other construction joints, shall be solidly closed with STAUF repair resin and floor brackets. Cavities and indentations can be filled with...
