Proper floor base preparation is one of the most important factors for a successful installation of a wooden floor or a parquet.
You can start floor base installation only after making sure the humidity levels of the room and the concrete slab are appropriate. The relative humidity of the indoor area should preferably be 40 to 60 percent and the indoor temperature should be 15 to 25° C.
Wooden floor can be installed on the following bases:
– A concrete base with a moisture content of no more than 3%.
– Subfloors, panels or plywood with a moisture content of no more than 12%.
If a wooden floor is installed in a room with moisture sources (a basement, a swimming pool, etc.), waterproofing is required in order to prevent moisture from entering the wood.
A concrete base must be level, firm and even. A parquet is glued to the concrete base using a special adhesive which does not contain any water (SMP-930, WFR-T).
When installing a wooden floor over underfloor heating, the underfloor heating should be switched off 24 hours before the start of the installation.
