Hoping for some insights. We've painted plenty of walls in the past using basic Sherwin Williams or Lowes interior latex paints, never had any real problems.
moved into a new house this summer (new to us, built in the 60s) and got to painting. some of the rooms had very faint/subtle cigarette odor and so on some of the walls, after cleaning them with some TSP and water, we used BIN Shellac based primer first.
Anyway, we're finding now a couple months later, in more than a few spots (but not everywhere, and not everywhere even on a given wall) I think mostly in bathrooms (which are well vented) that the paint seems to be cracking. One one ceiling a quarter size piece peeled off. Here's a closeup photo that shows exactly what I mean. Any thoughts on why this happened and how to fix and prevent it elsewhere? I was thinking that maybe we painted acrylic over oil based, but I'm not sure what the pre-existing coatings were or how to tell. Even if it were, wouldn't using the shellac in between solve for that?
thoughts?
Thanks!
