We installed lumber liquidators, bellawood bolivian rosewood over a concrete floor using lumber liquidators instructions and products, in 2 mos. the floor buckled and warped badly, they not only would not stand behind it, they denied telling us we could install it over concrete, i called back and have them on tape telling us we could over concrete using their products,unfortunately, we can not use that tape in court, we ended up removing the wood, having a $8000.00 fire to dispose of it and installed Anderson pre finished flooring, this was 4 years ago and the Anderson floor has held up wonderful.I suggest to stay far away from lumber liquidators, they lie.
