Leveling and smoothing of concrete floors, cement screeds, calcium sulphate screeds, tile and slab coverings and other load-bearing substrates.

Manufacture of plane and smooth surfaces for laying tiles, natural stone and other floor coverings.

As a wear layer in cellars, basements, hobby and games rooms, corridors, attics, storage rooms and storage areas.

Manufacture of wear layers in commercial and industrial areas.

For the indoor application.


Gray powder with special cements, good dispersible plastics and selected fillers. When mixed with water, a smooth, self-leveling, smoothing and pumpable mortar is produced, which can be processed for approx. 30 minutes and can be walked on after approx. 2 hours.

The mortar hardens by hydration and drying to a low-stress mass so that cracking is nearly eliminated.
