I want to lay down a wood floor in my 24'x24' garage. It has a reasonably clean slab, 7 years old, and the house plans called for a vapor barrier under the concrete. My goals are a comfortable and safe work surface and moisture control. I live on the eastern Shore of Maryland some 300 yards from the Chesapeake and with the high humidity the existing slab is frequently wet with condensation. My rough plan is to lay out a vapor barrier then float Advantec over 3/4 ridged green foam from Lowes. I was also considering using strips of 3/4 pressure treated plywood as floating sleepers, with the idea of still being able to drive a vehicle into the shop if necessary. An added challenge is that the shop is presently full of piled full of tools and shop stuff, that will stay in the garage and have to be moved at least twice during the installation.
I would appreciate any feed back about the feasibility of this plan. Thanks, Woody
