This subject is almost as hot as politics - people are so passionate about it! In my opinion there is nothing uglier than a brick fireplace! I want to paint mine, but every time I ask someone what to use I get nothing but insults and outrage! I have an identical fireplace upstairs that is painted and it looks so much better than the one in the living room. It never looks dirty and it never peels or chips - I'm surprised by the level of vitriol here! I'm just going to buy a bucket of paint and hope for the best!
