I "restored" a bathroom that had had a heavy wall paper that did not come off neatly. I repaired the walls and ceiling and skim coated much of the wall. I also sanded and repainted a shower ceiling. I found numerous recommendations for Zinsser BIN primer and rolled that over all of the prep'ed areas. There were one or two coats on the primer, depending on initial coverage. The primer was allow to dry at least a day. The walls and ceilings were then painted with at least two coats of normal household wall paints.
Three months afterwards, the shower ceiling started cracking and pealing. A year or so later other areas started to do the same. From the chips, it looks its the primer that pealed away, not the paint from the primer.
So, I now have to redo the entire bathroom.
Did I get a bad batch of primer?
Is there a better product to use?
Even in areas that from a distance look good, a closeup reveals that the cracks are everywhere.
And an unrelated question ;-) all of the pictures got rotated 90 degrees when I uploaded them. Is that normal here?
