Grinding a concrete slab is important because it helps to create a smooth and level surface for the wood floor to be installed on. Any bumps or uneven areas in the concrete can cause problems with the installation and may lead to a floor that is not level or stable. Additionally, grinding the concrete slab can help to remove any existing coatings or adhesives that may interfere with the installation of the wood floor.

Applying a vapor barrier, such as Wakol PU280, is also important because it helps to prevent moisture from seeping up through the concrete slab and into the wood floor. Moisture can cause the wood to warp, buckle, or otherwise become damaged, so it is important to take steps to prevent moisture from penetrating the floor. The Wakol PU280 barrier is specifically designed to provide a strong moisture barrier that can protect the wood floor from damage caused by moisture.



Overall, grinding the concrete slab and applying a vapor barrier like Wakol PU280 are important steps to take when installing a wood floor. By doing so, you can help to ensure that the floor is level, stable, and protected from moisture, which can help to extend its lifespan and prevent costly repairs down the line.
