In November, we painted 2 rooms semi-gloss, over satin. We did not prime, not knowing we had to. Now it peels off super easy. It’s not peeling on its own, just if it’s nicked or scratched, but I am able to peel it off in chunks, like nail polish. We obviously need to fix this. So question is; Do we have to scrape off all the new paint, THEN prime? Or can we prime over the existing paint and repaint again, and not have this issue? We used Glidden.
