CASEA Casufloor C25 F5 – Alpha Hemihydrate Flowing Screed
Alpha Hemihydrate screed CASEA Casufloor C25/F5 is a pumpable, high-quality screed material based on Calcium Sulphate. It is supplied as a pre-blended dry powder and is designed for application at thicknesses of between 30 and 90 mm. Casufloor C25/F5 complies with EN13813: CA-C25-F5 and is CE-marked.
CASEA Casufloor C25/F5 – Alpha Hemihydrate Screed is suitable for floors in homes, offices, public buildings and places exposed to similar loads. The product may be applied as a levelling screed directly onto a load bearing floor, unbonded on a separating barrier (polytheen), as a floating floor and is particularly suited in conjunction with underfloor heating or cavity floors. Casufloor C25/F5 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.
