Areas of application: • ASO®-Unigrund-S is used as a primer to improve the adhesion to absorbent and non-absorbent substrates prior to the installation of ceramic finishes with cementbased or dispersionbased SCHOMBURG thin or midbed adhesives. • ASO®-Unigrund-S is also suitable for priming clean, old, load-bearing tiled finishes, which have been levelled up to a maximum thickness of 20 mm with SOLOPLAN®-30 or ASO®-NM15. • ASO®-Unigrund-S reduces the porosity of the substrate and protects moisture sensitive substrates from the water in cementbased adhesives. • ASO®-Unigrund-S 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.

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.

Properties: • High adhesion strength to non-absorbent substrates • High grip primer once dried due to the silicate based aggregates • Rapid drying • Universal application • For absorbent and nonabsorbent substrates • Low emissions • Solvent free • For interior and exterior use
Product preparation: Shake thoroughly before use. Evenly apply a thin coat of ASO®-Unigrund-S at right angles with a foam or lamb’s wool roller. Use neat on non-absorbent substrates, on absorbent substrates dilute 1:1 with water. On nonporous substrates further processes may only be carried out once completely dry. Drying time approx. 1 hour. On absorbent substrates tiles can be laid as soon as the ASO®-Unigrund-S is surface dry – approx. 5 minutes – and touch-dry. The dry coating is transparent-pink and sand grey. When using externally, protect ASO®-Unigrund-S with a bonded waterproofing system for use beneath tiled finishes e.g. AQUAFIN®-2K/M or AQUAFIN®-RS300.
