Levelling mortars
Floor leveling: mortars for leveling subfloors
A perfect end result starts with a good foundation. That also applies to choosing the right self-leveling compound. There are two types of self-levelers: cementitious and gypsum-based. Both have important differences between them. But they share an important characteristic: they greatly please the flooring installer, as our leveling mortars are almost immediately ready for the final finish layer. Our cementitious self-leveling mortar is sought after for its precisely predictable drying and curing process. Our gypsum-based self-levelers excel on sensitive substrates and exhibit less shrinkage or expansion.

When do you use plaster leveling compounds and when do you use cement variants?
- On anhydrite surfaces you always use a plaster-based leveling compound.
- In addition, the fiber variant is the solution for the so-called Screed floor such as Fermacell and Rigidur.
- On standard stony surfaces, cement-based leveling compounds are the most common choice. In general, they are quickly ready for the next floor finish.
What is the waiting time before a coating can be applied over the leveling compound?
With almost all variants it is possible with a layer thickness of 3 mm. Apply a finish after 12 hours (at 20 degrees and between 50%-70% RH). Thicker layers and higher humidity require more drying time.
