Hello.. I am priming newly patched/repaired plaster walls with PVA
primer. The walls were never painted before- covered w/wallpaper. I
accidently rubbed up an area in a tight spot and a smudge occured.. I
tried to fix it, but it is peeling now. and, off comes big shards of
it off the bare plaster patch. when it fully dries, will I be ok to
sand the edges and reprime the area?
