How to remove painted-over wallpaper paste?
Hi, I am new here. We just removed wallpaper in the kitchen, cleaned the glue and found a very uneven painted surface. It is clearly a thick layer of dried wallpaper paste painted over or primed over. Surprisingly, it holds really well, no pealing. It does come off when sprayed with wallpaper removal stuff, but this is very tedious and slow. I've tried to use latex paint removal paste, but that was a mistake - no progress, but a big sticky mess. I know how to patch a drywall, but have never tried to skimcoat the whole wall before.
