Re: Reusing 1/2-inch Knotty Pine Paneling as Flooring
I can see a few problems with your idea. 1)the varnish is probably to soft for floor traffic so it would have to be refinished 2) if you sand it ½"is pretty thin to start with. 3) you would need to put down a vapor barrier on the concrete and install nailers 4) if you don't use tongue and grove the boards will be uneven in about a hour and a half. Personally I don't think it would be worth the effort.
