How to prepare tiles before application?
Updated: 15.07.2026

Tiles must be degreased, roughened as needed, checked for hollow spots and treated with a reinforcement layer.
Detailed answer
Before application, check the tiles by tapping, degrease them and remove any loose areas. Joints and smooth surfaces need to be covered with a basic reinforcement layer to prevent visible lines. For non-absorbent surfaces, Primer Plus is commonly used as an adhesion layer and to secure the reinforcement mesh. The reinforcement mesh should be fixed with Primer Plus primer.
Common mistakes
- application on dusty or non-cohesive substrates
- skipping checking for hollow spots and cracks
- insufficient degreasing and priming
