We are an older couple and have had water damage to our living room ceiling (old roof problem---which has been resolved); however, we had (a couple of times in the past) tried to repair cracks, plaster and sand(not well) and painted our old plaster ceiling with sand paint....which has started to bubble and peel....the ceiling does have cracks....we have tried to scrap the many layers of paint....the house is over 80 years old....and besides being a tedious job...I don't think we have the strength to continue....any suggestions regarding on how to proceed, what tools to use, suggestions, etc. or how to find a reliable contractor in our area who could resolve this problem, would very much be greatly be appreciated. We are living on a limited income so that is why we tried to resolve this problem ourselves.
