SMET LiteFlo® Lightweight Flowing Screed is suitable 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 (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.




SUPAFLO® is the ultimate screed solution and is at the forefront of screed technology.
