I first removed wallpaper and marked the walls pretty badly in the process. So I patched with spackle, sanded and primed with an oil base Kilz primer. I let it dry for 48 hours and painted with a semi-gloss deep purple Glidden paint.
Needless to say, every blemish and imperfection showed when the paint dried. Four weeks later, I decided to change the color and the sheen, so I started to scuff/sand the existing wall. As I was doing this, the paint started peeling like rubber on most of the wall, but not all. What do I do next to prepare to paint again while avoiding peeling? I bought a Ralph Lauren textured paint to hopefully hide most imperfections this time around.
Also, why did the paint peel like this? I’ve never seen this happen, it came off in sheets in some places.
