Application

SMET LiteFlo® Lightweight Flowing Screed is suitable for floors in homes, offices, public buildings and places exposed to similar loads. Suitbale for application in high-rise buildings and over timber suspended floors.

It 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 suited in conjunction with underfloor heating or cavity floors. However, when using LiteFlo® in combination with underfloor heating, it should be noted that LiteFlo® has a low thermal conductivity. LiteFlo® 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.
