Last time I did it I used this after power washing.
I too live in the woods and get mildew/algae/moss on my deck. Power wash cleans off and this has done the best job so far of keeping the deck cleaner and stain free. Applies with a weed sprayer. I went over certain areas 2 or 3 times as I could see it got soaked up fast and in others didn't need it. When it pooled I wiped it up.
And I also have a concrete patio that needs power washing and sealing just like the wood deck. I used this stuff. Still looks good.
I don't expect it will last more than 2 years but it's easy to do and I do not like the look of painted wood for a deck so wanted something clear.
