For info, the chipping has only started happening because I've been going around some of the loose lining paper seams and repairing with Solvite wallpaper paste. As soon as I go over the glued area with a seam roller, unfortunately some of the paint is coming off, which hopefully you can see from the image.
I've only done a small area so far, but I to need tidy up numerous loose seams in the room so the issue will definitely exacerbate. I've been advised to use Zinseer peel stop prior to painting, so am hoping this will hopefully prevent issues longer term and future proof the walls if I want to paint again e.g. in a different colour several years from now? Am hoping I will just be able to paint over the walls due to the prep I intend to do now?
I also plan on going over the seems with some filler to make them less visible. So should I use the filler on the seams first, Zinseer second, then paint thirs? Or Zinseer, filler, then paint? Etc. Etc.
Any tips and advice would be greatly appreciated. Thank you.
