Application

Used as a substrate for the following flooring types:

  • Wooden.
  • Vinyl.
  • Linoleum.
  • Carpet.
  • Ceramic tiles.
  • Stone floors (if using materials that do not exert excessive weight on the structure).

The screed moisture content should be measured using a carbide hygrometer before applying the floor coverings; this must be less than 3%.

Must be used in its original state, without the addition of other materials.

Consult manufacturer's literature for details on recommended substrate preparation and mixing instructions.
