A pumpable high-quality calcium sulfate screed for application at thicknesses between 20-90 mm.
CASEA Sudanit 280 Alpha Hemihydrate Screed is suitable for internal use for floors in homes, offices, public buildings and places exposed to similar loads. It may be applied as a levelling screed directly onto a load bearing floor, unbonded on a separating barrier (polythene) or as a floating floor and is particularly suited in conjunction with underfloor heating or cavity floors. It 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.
Südanit 280 Alpha Hemihydrate Screed is a pumpable, high-quality screed material based on calcium sulfate. It is supplied using a pre-blended compound and is mixed on site with a special blend of approved aggregates to EN 13813: 2002. It is designed for application at thicknesses of 20–90 mm. Südanit 280 Alpha Hemi Hydrate Binder complies with EN 13454-1: 2004 and is CE marked.
