The sub floor must be porous to have a strong adhesion between the glue and the sub floor.
If installed on a wooden sub floor, the moisture content of the wood shall not exceed 10%. In addition, the underside of the wood subfloor must be completely dry. If there is crawling space under the wooden floor, it must be ventilated. Remove all obstacles and ensure adequate ventilation (at least 4 cm per square meter of floor ² Main ventilation opening). The floor must be covered with plywood of at least 6 mm. Make sure that any obstructions are removed. Shaping shall be done with ring shank nails in grid format, 75 mm girth and 150 mm center.

The horizontal plate must be fixed with screws every 30 cm. The crawl space under the wooden floor must be fully ventilated. Remove all obstacles and ensure adequate ventilation (at least 4 cm per square meter of floor ² Main ventilation opening). The moisture content of wood shall not exceed 10%.
