We bought our house a couple years ago and are looking to redo the floors on the ground floor. The existing flooring is engineered wood glued to the concrete slab foundation. The question is, can we lay engineered floors or hardwood floors on top of that? What would we use, glue, nails??
The other question is if we CAN lay new floors on top of the old one (without ripping it all out), can we use an electric floor heating system in what is becoming a club sandwich of a floor?
