ASO-Unigrund-P reduces the absorption of substrates, binds surface dust, consolidates, prevents rapid water loss from levelling compounds. ASO-Unigrund-P is used for priming absorbent and lightly sanded substrates e.g. gypsum-based construction materials (plaster, interlocking gypsum slabs, boards, screeds), concrete, masonry work, marble, granite and similar substrates. Suitable as an adhesion promoter for surface applied waterproof membranes (e.g. SANIFLEX, AQUAFIN-2K/M), thin-bedadhesives such as LIGHTFLEX, MONOFLEX-XL, SOLOFLEX, AK7P, UNIFIX as well as wall and floor levelling compounds such as SOLOCRET-15, SOLOPLAN-30-PLUS and ASO-NM15. It is also suitable for exterior use.
