I just spent two weeks covering the floor of my 18' × 54' cedar deck with Behr's Deck Over. I live in Atlanta. Looks good in the morning when it's cool. As it gets warmer it starts showing white blotches all over my deck which is now ruined.
I ran a little experiment. I took an ice cube and placed in the middle of one of the white blotches and almost immediately it turned darker.
I'm no scientist, but I believe that there is something in this paint that has an adverse reaction when the temperature goes up.
