We have a house that was built in 1956 with sheetrock walls and ceilings. 10 years ago we bought it and painted every surface. A few years ago we noticed places on the ceiling where paint was peeling. When I started pulling the pieces seemed to be the paper off of the sheetrock ceiling and every layer of paint ever put on. I chipped until no more would come off. I scimmed on drywall mud to smooth the edges and bond to the bare drywall, sanded and painted. Now some of the places are starting to peel again.
Does anybody know what would cause the peeling down to the bare drywall?
Thanks for your help.
