A small portion of my ceiling bubbled up (unfortunately I keep getting an error and am unable to attach an image). It measures about 4 inches long. I had a contractor in to assess the damage for repairs. He said the entire rooms ceiling needs to be removed and re-sprayed otherwise a patch wouldn't match the rest of the room in terms of color. I certainly think this is overkill as last year I patched a small portion of the ceiling in another room and to this day it's nearly impossible to see. Any advice? Thanks!
