Anhydrite screed designed for application thicknesses between 20–90 mm.
The 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, or as a floating floor and is particularly suited in conjunction with underfloor heating or cavity floors.
Can 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.
Südanit 300 Anhydrite Screed is a pumpable, high-quality screed material based on calcium sulfate. It is designed for application at thicknesses of between 20 and 90 mm.
