How many layers of Aqua Base are applied?
Updated: 15.07.2026
✓
Usually one layer; two layers may be applied for reinforcement and covering old tiles.
Detailed answer
Apply Aqua Base with a stainless steel trowel in a thin layer, pressing it into the substrate. The correct thickness is determined by the grain size of the material, typically up to 1 mm. For the reinforcement layer or old tiles, two layers might be necessary. On floors, it is advisable to allow the layer to cure longer before proceeding, typically until the next day.
Common mistakes
- applying a thick layer instead of a thin grain-sized coat
- sanding without thorough dust removal
- rushing between layers and not allowing proper drying time
