Intended for executing cement floor bases and flooring layers, as well as similar pressure, base layers, slope-shaping layers, both indoors and outdoors.

Used as base in floor heating systems, applied on thermal insulation, separating layer and binding with the groundwork.

The screed can also be used to execute other elements poured directly at the construction site, such as: foundations, lintels, stairs, ceilings - after applying sufficient reinforcement.

Minimal layer thickness: base binding with the groundwork > 25 mm; base on separating layer > 35 mm; base "floating" on the thermal and/or acoustic insulation layer > 40 mm; anhydrite base in the floor heating system -> 45 mm (external diameter of the heating element + thickness of the layer above heating elements min. 30 mm).

Applied as base for ceramic tiles, synthetic lining, panels, parquet, etc.
