CASEA RADDIPLUS NA Rapid Alpha Hemihydrate Floor Screed Binder
RADDIPLUS NA Rapid Alpha Hemihydrate Binder is a specially formulated calcium sulphate binder suitable for the production of rapid self-drying, top-quality, self-levelling (flowing) floor screeds, simply by blending with suitable sand and water on site. CASEA RADDIPLUS NA Rapid Alpha Hemihydrate Binder complies with EN 13454-1:2004 and is CE marked.
RADDIPLUS NA Rapid Screed is suitable for floors in homes, offices, public buildings, and places exposed to similar loads. CASEA RADDIPLUS NA Rapid Screed 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. CASEA RADDIPLUS NA Rapid 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.
