Attaching the finished plywood on pressure treated plywood??
I am making a shed and for flooring I am using pressure treated plywood and then finishing it with AC grade plywood.
How should I attach the finished plywood on top of the pressure treated subfloor plywood. Since there is a moisture difference, do I need to put some sort of vapor barrier in between? If yes what kind of?
What kind of adhesive I should be using to attach these? Or should I just nail it on the joists locations?
