Application:

• self-leveling leveling compound for floors, for making a 10-40 mm thick layer
• as a floor underlay combined with the base, on the distribution layer (screed thickness min. 25 mm)
• on calcium sulphate based substrates (also on heating floor underlays)
• in thin-layer floor heating combined with the ground, on the distribution layer and the insulation layer
• for uniform and smooth floor surfaces,
• for leveling unevenness of floor screeds before laying ceramic tiles, flexible and carpet floor coverings, natural stone panels, laminate and parquet.

Consumption / Performance:

• 10 mm 18 kg / m2

It turns out that KNAUF Screed Leveling N440 40KG is an effectively prepared dry mortar based on calcium sulfate, selected aggregates and special additives, which is ready to be made. Thanks to it, making smooth surfaces of floors and leveling the unevenness of floor underlays becomes much easier!
