I went with the 3/8 cdx plywood, over top the now fixed 3/4 inch plywood sub floor. What’s the best way to fasten it down? Glue? Nails? Screws? Combination? I am afraid over time, nails will pry up. I have 16 gauge 1 inch nails/gun. Deck screws don’t come in 1 inch that I know of. I want to avoid at all costs, the original screws I used to fasten the sub floor to the joists, those caused me a lot of problems.
