I have a concrete floor I'm going to put click and lock flooring on. It is quite level and smooth but it's not perfect. I think I'm going to cover it on lauan, but I noticed that OSB is quite a bit cheaper. The concrete floor has a vapor barrier under it and also a waterproof coating on it. Can I use OSB for click and lock flooring or is it too bumpy?
