What deck stain would you suggest for cedar decks in Portland, OR? I am moving back soon and recently bought a house that has 3 separate decks that have not been well-cared for and have mold/mildew on them. Once I get them cleaned, I want the best product to prevent mold/mildew in the future (and, of course, I'll take better care of them myself by cleaning/staining them regularly). Unlike some of the other brands you reviewed, your top-choice TWP brands were not rated in terms of mold/mildew. Would appreciate your help as the online reviews for deck stains are some of the most contradictory of any product on the market, it seems! Thanks.
TWP do rate very well with mold and mildew. They are the only stain in the market that contains a EPA registered mold preservative. The TWP works better then any other brand of oil based wood stain when it comes to mold. Besides that I would also look at the Defy Extreme. It is great at mold prevention.
