Engineering concrete floating slab flooring.
As needed use a concrete grinder you may want to rent one to remove any coating and to slightly roughen the concrete surface so the adhesive will stick.

Boards adhere well to the rough surface of the concrete subfloor and therefore lead to less gaps or planks lifting and buckling.
To avoid that and other problems there are steps we follow to ensure the slab is clean flat and relatively dry.
