Areas of application: • ASO®-Unigrund-K reduces the absorption of substrates, binds surface dust, consolidates, prevents rapid water loss from levelling compounds. • ASO®-Unigrund-K is used for priming absorbent and lightly sanded substrates e.g. gypsum-based construction materials (plaster, interlocking gypsum slabs, boards, screeds), concrete, masonry work and similar. • ASO®-Unigrund-K is suitable as an adhesion promoter for surface applied waterproof membranes (e.g. SANIFLEX, AQUAFIN®-2K/M), thin-bed adhesives as well as wall and floor levelling compounds such as SOLOCRET®-50, SOLOPLAN®-30 and ASO®-NM15. It is also suitable for exterior use.

Product preparation: ASO®-Unigrund-K is diluted 1:3 to 1:6 with water dependent on the substrate condition, the application involved and the absorption. Beneath wall and floor levelling compounds use at a mix ratio of 1:3 with water. Application is with a paint brush, brush or a fine-pored sponge roller but it can also be sprayed with suitable equipment. Avoid applying too thickly or forming puddles. ASO®-Unigrund-K must be fully dry before further work can be carried out on the primed surface.
Properties: • Concentrate, highly dilutable • Rapid drying • Universal application • Resistant to water and alkalis • Low emission • Solvent free • For interior and exterior use
Application: The substrate must be load-bearing, clean, dry and free from materials, which will impede adhesion. Flow screeds must be abraded and vacuumed. Remove unstable or weakly bonded layers e.g. release agents, residues of old adhesive, levelling layers, surface finishes and paints, by mechanical scrubbing, planing, scabbling or shot-blasting.
