When I purchased my house, unbeknownst to me the ceilings, except kitchen and baths, were painted with Calcimine sp? Later I painted the kitchen and baths with mildew proof paint and of course no problem. Some years later I painted one of the bedroom ceilings and later the paint began to peel in spots. I can scrape around the edges of the peel and it looks sort of OK for a while but then those edges begin to peel again.
Now I know that there are special primers available which might have helped me. My problem now is that I can’t get the latex ceiling paint off to start over. I have tried wetting it first and scraping keeping it wet overnight but I can’t get it to peel. This ceiling has blown in insulation and is a heated space above.
Boy am I glad I didn’t paint all my ceilings… What can I do ??
Realize that a “perfect” job is IMPOSSIBLE… then scrape off as much as possible to firm edges, then prime the whole ceiling with a Pigmented Shellac Sealer Primer, then top coat with a Sherwin Williams product (color of choice, flat finish)…
