The paint is peeling away from the drywall in the upstairs of our house. It appears that a new coat of pait was added on the original coat which were never primed. We were able to use a putty knife and a heat gun and get down to the drywall fairly easily but the paint is still adhered where there was tape or putty.
We are looking for advice, should we putty and sand, or apply a spray ceiling on or hire someone to texture the ceiling? We are hesitant to do anything like popcorn, which is going out of style. We would like to DIY but we are aware that we might only get 1 shot to get it right.
