Application

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.
