Key Facts

The substrate system from SCHOMBURG helps recognition of wall and floor substrates and supports you in the correct selection of primer and leveller. On perfectly prepared substrates, further application systems can be built such as for example the bathroom system.

Within the substrate system, you will find the ideal product for preparing and levelling your substrate. Alongside ASO-Unigrund primers, the system also offers the smoothing compound SOLOPLAN-30-PLUS and the compatible levelling mortar SOLOCRET-60. Your solution to levelling walls and floors.

As an accessory, the system is extended with the rapid hardening silicate-based casting resin ASODUR-GH-S. The product for effective sealing of cracks in the substrate. The substrate system from SCHOMBURG makes it simple for you to level substrates and prime the areas.

The “wall” and “Floor” substrate systems are the basis for further systems from SCHOMBURG.
