CASEA RADDIPLUS T – Thermal Anhydrite Floor Screed Binder (was previously Sudanit 400)

CASEA RADDIPLUS T – Thermal Anhydrite Binder is a specially formulated thermal calcium sulphate binder suitable for the production of top-quality self levelling (flowing) floor screeds, simply by blending with suitable sand and water on site or ready-mix plant. RADDIPLUS T complies with EN 13454-1 and is CE marked.

RADDIPLUS T Screed is suitable for floors in homes, offices, public buildings and places exposed to similar loads. RADDIPLUS T Screed may be applied as a levelling screed directly onto a load bearing floor, unbonded on a separating barrier (polythene), as a floating floor and is particularly suited in conjunction with underfloor heating or cavity floors. RADDIPLUS T 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. Contact SMET for advice on which to use.
