Mayayana submitted this idea :
Try scraping off the paint and use a stone or metal wall scraper to get
the old paint off, then use driwall topping compound and a trowel to
smooth the wall.


Are you serious? He said most of it's stuck. What
you're proposing probably means several *days* of
scraping work, then skim coating the entire wall
with joint compound after getting it hacked up.
All for no good reason. Anyone who had to do such
a thing for some reason would be better off drywalling
over it.

I never said it would be easy. Are you afraid of a little work? ^^

OP asked about primer. Not how to do the work.
