old wallboard

i have wallpaper that was put on what seems to be first generation drywall. no primer. it may come off easily as it is very old but what is underneath is like cardboard. can i paint over this with a good primer then latex? or do i need to have a skim coat on top?

Unless the original wall was sized then you will more than likely have to skim and prime or better yet prime, lightly sand off any very rough paper and skim and sand and then prime to prep for final paint.

Have you removed all the wallpaper yet? It's rare for wallpaper to come off without damaging unpainted drywall. If the wall is smooth - primer and paint might be enough. If there is any wallpaper adhesive remaining on the wall you must use either an oil base primer or Zinnser's Gardz. The same is true for any areas where the drywall paper is missing.

btw - welcome to the forums!
