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.


Description

A factory-produced, pumpable, high-quality screed material based on calcium sulphate. It’s supplied to site in pre-mixed 27kg bags or site silos. LiteFlo® is designed for application at thicknesses of between 20 and 70 mm, complies with EN 13813: 2002 and is CE marked.


Features and benefits:

  • Lightweight - high yield, 43kg per m2 @ 40 mm.
  • 30% weight reduction compared to normal CA screed.
  • Smooth laitance-free finish.
  • Pumpable.
  • Full encapsulation of pipes and services.
  • Yield: 1.08 kg/mm/m².
  • CE Marked.
  • EN 13813: 2002.
  • Absolutely ideal for application in high-rise buildings.
  • For application at thicknesses of between 20 and 90 mm.
  • Perfectly level floors.
  • Installed nationwide by Smet Supported Partners.
  • Pumpable – first of its kind available.
  • Installed nationwide by Smet Supported Partners.
  • EPD certified – certificate available here.
  • Sustainable – as this calcium Sulphate binder naturally embodies less carbon than a cement-based binder.
  • German made EN 13813: 2002
