We painted our greed screen wall this past weekend with very good results. We ended up putting a third coat on because we are a little nutty, but 2 coats would have been plenty. One wall/3 coats used a half gallon of paint. This paint doesn't have a strong odor which was a nice surprise. I was afraid the room would need a lot of ventilation and it's been so hot I wasn't looking forward to having to prop the door open. We put it on a primed wall. The first coat barely covered and I was concerned, but the second coat did the trick. Even so I did put on a third coat. Our space isn't done but we tested it out and it worked perfectly. The picture shows our messy work counter, sorry, but this was after 2 coats.
