CASEA Casufloor DE is a calcium sulfate based, polymer-modified, levelling screed compound, ideal for renovations or levelling cementitious, calcium sulfate and concrete based floors. The composition of the material makes it ideal to use over heated floor systems, layer thickness 10–30 mm. The material complies with EN13813:2002 and is CE marked – Designation: CA-C30-F7.


  • Smooth laitance free finish.
  • Pumpable – High flowability.
  • Easy trafficking.
  • Very low shrinkage.
  • Reduced drying times.
  • CE marked.
  • EN 13813:2002.


Casufloor DE is used in renovation of apartments, offices and public buildings as a levelling material and with Roth’s QE Underfloor Heating System. The screed is for internal use and can be covered with all common floor coverings. If a cement based adhesive or smoothing compound is required, the surface of the screed must be sealed first using an appropriate acrylic primer/ sealer. It is not suitable for wetrooms.
