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 I choose a gypsum-bound plaster mortar or a cement-bound plaster mortar? And can I combine these?

The choice between gypsum mortar and cement mortar depends on the application. Plaster mortar is a good choice for dry indoor applications where a smooth finish is important. Plaster mortar is not ideal in wet areas. Cement mortar is resistant to moisture and extreme temperatures and is a better choice for wet areas and outdoor applications. Cement mortar has much higher strength and is more durable than gypsum mortar. 

Never simply apply a cement-based plaster mortar to a plaster-based surface. Use specially suitable plaster mortars, such as our 90GR omnimix, W100 R omnimix or W100R LIGHT omnimix.

What determines whether the leveling compound is suitable for the chosen final finish?

The combination of flatness, smoothness and hardness of the top layer determines whether a soft or hard covering can be placed, such as tiles or PVC. A rougher top layer is much less important for a finish with tiles, while for a floor finish with, for example, PVC and marmoleum, an extremely smooth top layer is necessary. The flow rate may differ per grade or type of leveling compound. But with proper use, all our leveling compounds will become perfectly flat.

What temperature should the subfloor be during leveling?

During processing it is necessary to keep the temperature of the subfloor, space and material between 15 °C and 25 °C. In addition, the relative 65% of the lager must be before, during and a few days after maceration!
