Hardwood Floor Installation On Concrete Slabs
May 1st, 2008
It is not a good idea to install solid wood floors over a concrete slab. Concrete is a porous substance that allows moisture to seep through. Solid hardwood floors can be severely damaged by moisture. Installing hardwood floors on a slab may void the warranty. In some very dry climates, it is acceptable to install solid hardwood floors over a slab if care is taken to protect the floor. First, plastic should be put down on the slab and all seams taped thoroughly. After the plastic is in place, three quarter inch marine plywood should be used as a subfloor. Marine plywood is water resistance. Once the plywood is down, the solid hardwood floors can be nailed down directly to the plywood.
