In my kitchen the previous owners wall papered over a brick chimney. We did not realize this till we took down the wall paper & noticed huge chucks of plaster coming off with the wall paper. Apparently there is moister that set in and it made the plaster crumble. I am not sure what to do. Should I just replaster the area & paint over it? Or is there a better solution?
If there are large chunks of plaster coming off, I doubt you'll be able to just re-plaster the bad places. The integrity of the plaster is likely gone. Is it "chalky" or "sandy" feeling where the pieces came off?? New mud/plaster may not adhere. You may want to get a pro to take a look at it and advise rather than attempt to fix it and just waste your time. And above all, you need to find and resolve the moisture issue. I'm not in the plastering business, but have done some plaster repairs (with drywall materials), so you may get some more replies with better advice. Best of luck...
