I believe there's some confusion here about what is meant by "decks." Unless I've lost the plot completely, the original poster was asking about solid plywood decking covered with a continuous polymer coating which provides total water, UV and abrasion protection as long as its integrity is maintained. This is a different approach to decking from the more typical residential wood or "Trex" planks with spaces between them. My own best experiences with solid plywood decking involved using butyl rubber sheets, a.k.a. "rubber roofing," glued in place to form a continuous weather barrier. This material lasts essentially forever. The butyl was covered with floating wood decking consisting of sleepers and deck boards. This is probably far more elaborate (and expensive) than desired, but because the wear surface in such a system is distinct from the weatherproofing membrane, expected lifespan much greater. By using treated or composite materials for the walking surface, a deck might last decades without further attention. Hope this helps.
