I have a 400 squard foot deck, in northern California, it gets very cold with little snow in the winter, and hot during the summer months. My problem is that I used BEHR Premium Wood-Toned Deck, Fence & Siding Weatherproofing Wood Finish. Everyyear I have to re-coat the stain on my deck, because the stain peels. I was told that I am using too much stain on the deck, and I have to sand all the stain off the boards and re-stain. Any suggestion???
