Application

Suitable for floors in homes, offices, public buildings and places exposed to similar loads. Can also be applied as a levelling screed directly onto a load bearing floor, unbonded on a separating barrier (polythene), as a floating floor, and is suited in conjunction with underfloor heating or cavity floors. Suitable substrates include concrete, thermal or acoustic insulation, and plastic membranes.

Should be covered with a floor finish such as tiles, linoleum, parquet, cork, carpet or a suitable coating. Not for use externally.
