I'm considering putting down a wood floor in my shop. I'm doing it mostly for comfort. It kills my back and feet. I've tried different shoes and the rubber mats with no luck. I have seen a couple of shops with wood floors and really liked the overall affect they have on the shop.
I wanted to run the process by you guys and get your input.
Step 1: Lay down vapor barrier. The floor is going over concrete. There is no visqueen under the slab. So the recommended practice is to put it on top of the concrete and tape the joints to stop moisture from coming through the new floor. I am not completely comfortable doing this because I think it creates moisture putting visqueen over concrete. A gentleman from Germany recommended felt over concrete which I think I like better. But I may do nothing since I'm in CA and it's pretty dry here. What do you guys think?
Step 2: Lay down 4x8 sheets of 1/2" thick sound board(fiber board). This is supposed to give the floor some cushion and resilience.
Step 3: Lay down 1 1/8" tongue and groove OSB. This is put down the opposite direction of the sound board. It is glued in the tongue and groove and the ends are biscuited and glued. It is similair to a floating laminate floor. Nothing gets fastened to the concrete.
Step 4: Sand entired floor with a floor sander. This takes out all the markings and evens the end joints.
Step 5: Apply polyurethane or similar product. Someone recommended a product called "Traffic". It is supposed to be good for high traffic areas and has a hardener in it.
I was told by my lumber suppier to go with 1 1/8" plywood sturdy floor. But the person I'm getting my info from did his whole shop (4,000 sq. ft.) with OSB and said it's holding up really good. He was told the same thing, to go with plywood. I think by using osb you get a little more cushion and comfort. Also there is no problem with putting heavy equipment right on top of the floor.
Let me know what you guys think.
