Q: I would like to install hardwood in my basement. I understand the moisture problems with basements, is there not a product out there that would seal the cement making it water proof? I was thinking of an epoxy paint, like the one they use on garage floors.
Would this stop ground moisture from penetrating the concrete? I would then use a plywood subfloor prior to installing the hardwood.
A: I would not suggest a paint, as it may also interfere with a proper bond with the adhesive for the engineered floor. There are numerous products on the market that serve to retard moisture. One such can be found at www.bostik-us.com. Follow the hardwood flooring links for bostik products to the surface preparation link. You can even watch a video telling us all about MVP sub floor treatment. Don’t forget to make some popcorn! Perhaps a less expensive approach would be to glue plastic sheeting (at least 4 mil) to the concrete using one of the Bostik adhesives which are all moisture resistant.
