The substrate system
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 ASOCRET-M30. 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.

1 Gypsum plaster
Suitable substrate for water penetration class W1-I. Adequately dry and not polished or finished with a felt pad in a dry environment and proven substrate.
2 Gypsum Plasterboard
Suitable substrate in internal area up to water penetration class W1-I. Tiles fixed direct. Observe manufacturer's loading statement.
3 Cement-based fibreboard
Suitable substrate in internal areas up to water penetration class W3-I. Resistant board substrate. Ideal for commercial kitchens or areas with high water penetration.

4
5 Tile
Acceptability in the system dependent on the substrate beneath the existing tile finish. Firmly bonded, free from dirt, dust, grease and plaster residues, a problem free substrate in renovation.
6 Concrete
Suitable substrate for mechanical stresses and high water penetration. Adequately old (as a rule after ca. 6 months) and free from laitance layers, binder rich areas and adhesion reducing materials. A substrate for the industrial environment.
7 Substrate with adhesive residues
Acceptability in the system dependent on the substrate beneath the existing tile adhesive.
8 Cement-lime render
Suitable substrate in internal and external area up to water penetration class W3-I. Roughly finished and not smoothed, an absolute Allrounder of substrates.
9 Cement-based render
Suitable substrate in internal and external areas up to water penetration class W3-I. The most pressure stabilized and non-sensitive amongst render/plaster substrates.
10
11 Tile
Floor
Application as a system dependent on the substrate beneath the existing tiling.
Well bonded, free from contamination, dust, grease and plaster residues, a problem free substrate for the renovation.

12 Concrete
Floor
Suitable substrate for mechanical stresses and high levels of water penetration. Adequately old (as a rule after ca. 6 months) and free from laitance layers, binder rich pockets and adhesion inhibiting materials. A substrate for an industrial environment.
Our product recommendations for you
Primer: ASO-Unigrund-GE
Smoothing compound: SOLOPLAN-30-PLUS
13 Screed (cement bound)
Suitable substrate in internal and external area up to water penetration class W3-I. Installed in conventional damp-earth consistency or as a flowable variant. Optional as a special construction as an accelerated or rapid screed.
14 Substrate with adhesive residues
Floor
Application as a system dependent on the substrate beneath the existing tile adhesive.
Our product recommendations for you
Primer: ASO-Unigrund-GE
Smoothing compound: SOLOPLAN-30-PLUS
15 Timber construction
Suitable substrate in dry internal area. Solid, screwed, free from deflection, levelled and uncoupled. Functional renovation.
16 Asphalt screed
Suitable interior substrate up to water penetration class W3-I. Adequately firm, unheated and protected from strong sunlight. Suitable to take tiles and thin layer smoothing compounds (<10 mm).
17 Screed (calcium sulfate bound)
Suitable interior substrate up to water penetration class W1-I. Applied conventionally in a damp earth consistency or as a flowing consistency. After abrading the surface and drying, it depends on the tile format!
18
Suitability for rooms with water penetration dependent on manufacturer. Suitability varies in accordance with manufacturer's information. A substrate with versatility. As a dry screed or as a hollow floor for direct installation of tiles or with wet construction with a calcium sulfate based screed. (Photo: © James Hardie Europe GmbH)
