We had an abatement company remove popcorn ceiling in our house last year, but I discovered that popcorn ceiling was also sprayed into the air duct opening. I don’t want to touch this stuff. Spray area is about the size of an air vent opening so I’d rather not have to hire anyone to look at it. Can I just use an aerosol can of paint to enclose better? If so what kind is best? via /r/DIY https://ift.tt/3b8UNyH
