Can someone please suggest a type of ply to use for the flooring? I went to Lowes this evening and they did not have 3/4 of anything. (not to mention I didnt see anything that was exterior grade) I asked for help and the dude started scratchin his head so I left.
I used exterior grade NON treated plywood for my floor. I sealed it with 2 coats of Olympic water seal before I built the shed. The support boards/posts are all treated, but the plywood is not. I have not had any issues with the plywood.
