I have a 5-year-old unfinished 18X20' P.T. deck that hasn't been water treated since we bought the house. It's looking kind of water . We live in Dartmouth Nova Scotia, we have our share of damp weather. You mentioned a new product coming on the market and to hold out on applying anything on the deck 'til spring.
Answer:
New products are always coming onto the market but about the best you'll find is a bid-degradable product that is a fairly recent arrival and its available at most good paint stores across the country (continent?).
