We currently have a 1960s house with a hodgepodge of flooring....parquet floor, carpet, and pergo (under which is linoleum), all installed on a (mostly) concrete subfloor. There are sections of the subfloor that are particle board and plywood where an addition to the home had been built in the 70s but otherwise the majority of the floor is concrete. In any event, the subfloor is not level in many places and humps and bumps are visible.
We want to rip everything out and put down hardwoods. We recognize that proper floor prep and leveling will be essential. However, we are getting very conflicting information as to the types of wood we should install. Some flooring companies recommend engineered wood glued to the concrete and others recommend short boards of solid hardwood glued to the concrete. We're getting so much conflicting advice that we're not certain as to which would be a better product to install onto concrete. We'll have a moisture test done first, and assuming everything is ok, what would you recommend?
