Südanit 280 Alpha Hemihydrate Screed is suitable for floors in homes, offices, public buildings, and places exposed to similar loads.

Südanit 280 Alpha Hemihydrate Screed 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. Südanit 280 Alpha Hemihydrate 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.
