Application

LiteFlo® is suitable for floors in homes, offices, public buildings, and places exposed to similar loads. LiteFlo® may be applied as a levelling screed directly onto a load-bearing floor, unbonded on a separating barrier (polyethene), as a floating floor and can be used 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.

SMET LiteFlo^® is supplied to sites in convenient 27 kg pre-mixed bags or in bulk site silos.
