I'm currently doing a job with extra white solid deckscapes from sherwin Williams. There are 36 five by ten decks stacked three high = 12 sets. We apply mostly by brush and the undersides by airless spray. Two coats is a minimum with this deckscape product on cedar at least. Sometimes some tanin still bleeds through brown, and another coat is needed. They reformulated the Cuprinol when they changed it to deckscapes somewhat I think, because the Cuprinol was slightly thicker and didn't bleed through as easily.
The story on these decks is the contracter put alkaloid white paint on them. They are peeling terribly because most of the paint will not stick on cedar, so we have to knock off all of the paint we can with a PW, scrape, sand and restain with multiple coats all of them. What a pain in the butt. Just my experience with the new Deckscapes.
