Concrete Floor Adhesive

what type of adhesive do i use to glue a solid wood floor to a concrete floor?
You should always use the manufacturers’ recommended adhesives for any flooring product. The flooring manufacturer will require you to go to the adhesive manufacturer for any warranty issues. However, if there is no recommended adhesive, we use Bostik’s Best for the majority of our wood installations. Before you install, make certain to allow the solid wood flooring to acclimate in the area in which it is to be installed for at least 48 hours prior to installation.
Be warned. Although we do install wood flooring directly to concrete slabs on a regular basis, if you decide to change floors later on, demo of the wood is a painstaking process.
