Has anyone pressured washed your boards with a zero tip point? Honestly, that what it looks like has happened.....washed and peeled the finish off. Like Wright Construction, we are almost exclusive CPG Products as well, and have never seen this type of problem before. This is our oldest Brownstone deck...5 yrs old now....since this photo was taken, the homeowner's have cut their only backyard tree down, and now get full sun all day. Once I read this thread, checked with them and same homeowners say it still looks great. The biggest problem they have is keeping the scuff marks off the darker board.
