  • Pumpable.
  • Under floor heating – full encapsulation.
  • Suitable for underlayment in wet areas.
  • Reduced drying times.
  • CE marked.
  • EN 13813: 2002.

Applications:

CASEA Casufloor C30/F6 Alpha Hemihydrate 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) or as a floating floor and is particularly suited in conjunction with underfloor heating or cavity floors.
