I have clad the outside of a shed with 9mm "exterior grade" ply, and battened over the joints to give a board & batten type appearance. After one bit of rain many patches of the ply have started to bubble, see picture for example.
Anything I can do or have I wasted my money on the ply and will it need more cladding on top of it? I haven't treated or painted it yet as it's only been on a couple of days, but I would have expected it to survive a few drops of rain :/
