CASEA Südanit 400 Thermal Anhydrite Binder
Südanit 400 Thermal Anhydrite Binder is a specially formulated calcium sulphate binder suitable for the production of top-quality, self-levelling (flowing) floor screeds, simply by blending with a suitable sand and water on site or ready-mix plant. Südanit 400 Thermal Anhydrite Binder complies with EN 13454-1: 2004 and is CE marked.
Südanit 400 Screed is suitable for floors in homes, offices, public buildings and places exposed to similar loads. Südanit 400 Screed may be applied as a levelling screed directly onto a load bearing floor, unbonded on a separating barrier (polyethene), as a floating floor and is particularly suited in conjunction with underfloor heating or cavity floors. Südanit 400 Screed should be covered with a floor finish such as tiles, linoleum, parquet, cork or carpet. If a cement based adhesive or smoothing compound is required the surface of the screed must first be sealed, using an appropriate acrylic primer/sealer.
