CEMEX Supaflo is a ready to use flowing floor screed based on alpha hemihydrate calcium sulfate. It is designed to be less labour intensive; up to ten times the area may be laid compared to traditional semi-dry screeds. It may also be laid at lesser thicknesses and the likelihood of shrinkage and curling is significantly reduced. As the system is laid on a debonding membrane, no cleaning or surface preparation need be carried out on the base surface.

Thickness (recommended minimum):

  • Floating: 35 mm.
  • Unbonded: 30 mm.
