But we are painting our ceilings. This summer I opened a cupboard door and a jar of V-8 juice fell out on to the counter, the cap cracked, it did another bounce on the counter and about a quarter of a cup splashed up and hit the ceiling. You wouldn't think a quarter cup could cover to much space but it sure did. The only way to clean it was to paint. Since our kitchen, dining room, living room and hall ceiling are all connected we are committed to painting the whole thing.
