Ask Eric Stromer a question here. I had a water leak from the sink on the 2nd floor. Now I have a stain on the popcorn ceiling and some of the popcorn fell off. I dont want to paint the whole ceiling because it is open to the family room living room and kitchen. the ceiling was painted 4 years ago and it still looks good. what can I do about the stain and some of the popcorn that fell off.
