How can I remove ceiling popcorn?
Mia, I pretty much agree with Maya. There are tools made just for the project. They have a scraper blade and a frame to hold a bag. They also have a long handle receptor. The idea is attach a bag to the frame, wet the ceiling with some water, then sctape the popcorn off. You will damage the rockwall and you will also find out the original contractor didn’t do a good finish job. You will have to do some sanding, mudding or repair work and possibly finish the seams properly. Best to remove all furniture and expect many hours of work.
