I live in Phoenix, Az, where it is Hot and Dry. I moved into my house about 5 years ago. I have a large redwood deck that was painted (not stained) when I moved in. The deck was probably installed around year 2000. The paint is peeling and I now need to repaint it. As well, I need to fill in large gaps in the wood (we are also replacing some boards). I read that the latex super deck peels in big chunks within a year and is a mess to remove. I went to Sherwin-Williams Williams, & they recommended their floor and porch enamel. After reading reviews, I don’t think that’s a good choice. Some say it is tacky & collects dirt. Mesquite leaves, pollen, & beans will fall on this deck & is subject to weather. Another Sherwin-Williams Sales kguy recommended Supreme Bond Primer, and paint over that with SW A-100. I don’t see how a flat latex paint is durable or cleanable enough for a deck. Hoping the wisdom of experienced painters can help me find the best products for this application. Thanks, all!
