Yep, that's the way to do it, use WBP ply and use an SBR primer on the UNDERSIDE and edges, if there's any movement in the floor at the moment then brace the joists, then get a good flexible adhesive suitable for ply, cement based ( bags ) not tubbed gear
You say use an SBR primer on the UNDERSIDE and edges, do you have to prime the Topside aswell of the ply ?
