Sopro AFS 561 CA Levelling Compound

Sopro AFS 561 CA Levelling Compound is a white, pumpable, flow-applied, self-levelling, rapid-set, alpha-hemihydrate-based filler used to level out gypsum-based/calcium sulphate-based (anhydrite and self-levelling anhydrite) screeds and board subfloors and to produce smooth, level, unbroken surfaces for subsequent laying of all kinds of flooring, e. g. ceramic, natural stone, textile and elastic coverings. The product can also be used on mastic asphalt and is suitable for floor heating systems. Optimum flow qualities by Superplasticizer (high performance liquefier).

Sopro AFS 561 CA Levelling Compound is a low-stress, flow-applied, alpha-hemihydrate-based filler used to produce smooth, unbroken surfaces for subsequent laying of floor coverings.  The product can be used on calcium sulphate-based (anhydrite and self-levelling anhydrite) screeds, gypsum-based screeds, alpha-hemihydrate-based screeds, cavity floor systems and board (e. g. gypsum plasterboard or gypsum fibreboard) subfloors. Also for use with cement screeds, magnesium oxychloride (magnesite) screeds and concrete. Particularly suitable as floor-levelling compound for mastic asphalt screeds. Sopro AFS 561 is only suitable for dry interiors. Building elements in contact with ground shall be waterproofed/damp-proofed by others in accordance with relevant standards.
