I bought an 1870 house a year and a half ago which was painted right before it sold. About half the walls are plaster and the other half have been redone with drywall. On the plaster walls, the paint is cracking and flaking off. There only appears only be one layer of paint with bare plaster behind so it was most likely wall papered before.
My question is what to do now? Obviously it’s probably going to have to be all scraped off, but what’s the cause and how can I prevent it from happening again?
