The main floor of my house is berber carpet over a water damaged and generally beat to hell oak strip floor. I think its even just 3/8″ thick-cheap stuff for a bargain house when built. I live in a late sixties (1960’s) townhouse where the modern style is there but not so vibrant. While it would be easier to freshen-up a more traditional place with mouldings, wainscote etc., I can’t get away with that in my place-at least not with a good conscience.
So, my point-I thought an interesting and inexpensive alternative might be installing 4×8 plywood as the finish floor. I’d pull up the old oak, lay down some of that Pergo type foam and then screw the plywood sheets on top.
The plywood ought to have a fairly thick top ply and the sheets could have an 1/8″ gap between them. I’d use exposed fasteners at maybe 12″OC. I might stain the whole thing grey or red -a semi-transparent stain. Top with poly and screen and re-coat every couple three years.
I wonder what anyone has to say about this. Have they seen it or heard stories about problems? I would not plan to really refinish it by sanding and would maybe crank the screws down once in a while.
