Curious as to the repercussions of laying 3/8" sheet plywood on top of the existing laminate floating floor (3/8") which would ideally create a 3/4" subfloor for a hardwood floor install. Could I make a subfloor like this??? Before laying hardwood fasten the whole thing to the concrete slab via powder accentuated nails?
Something just does not seem right about this...
