 Yeah, there's actually a special roller for that. It's like a slitted roller. It's a very thick roller that's got slits in it, and it's designed to squeeze the paint into that popcorn area, and that's exactly what I would do with it. I would paint it. It's going to look a lot better than cleaning it. You just can't clean that stuff. There's nothing cleanable about a popcorn ceiling. You've got to paint over it. Good luck with that project. Thanks so much for calling us at 888-MONEYPIT.
