As far as I'm concerned the only covering for a deck is vinyl
Never use that roll on rubber crap that they say will last for 10-15 years. That is the biggest load of horse manure you'll ever see ![icon_evil.gif](upload://1gvq2wV2azLs27xp71nuhZOKiSI.gif) I've see newer homes 3-5 years old, that the deck is in far worse shape than if they would have left it totally uncovered
MY theory is that the plywood expands and contracts causing cracking on the joints... then the moisture gets in there and the coating actually encourages
rot by holding the moisture under the areas where the coating actually sticks...ruining the deck faster than nothing at all.
Also, never use pressure treated plywood...it is only
designed to be used in a vertical position like a foundation wood wall. They won't guarantee it if it's used laying flat.
I believe good old fir plywood is still the best choice!
