Shed Floor covering
I just had a shed built and it has a pressure treated plywood floor. The shed is mainly for storage but I still want to add some kind of protection to the flooring. I am really really confused on what I should do. The shed is already built so I cannot paint the underside. Can anyone give me advise on how I can most economincally treat and protect the shed flooring? I am mainly concerned about protecting against long-term moisture damage. Thanks for your insight!
