If you insist on only sanding and painting over it, prime with oil
base primer. This will keep the paper from getting wet and bubbling
further when
it gets wet again from painting/mudding.

Question, have you had much luck putting latex over oil based primer?
I ask because my Mom taught me that's bad juju. Pretty much put oil
over oil. It was a bear when we had to paint a chair rail and window
setup that was oil based before and we needed to put latex over it.
Had to sand the dickens out of it to make it work.



Absolutely. In one place I got there was a bathroom that was painted over
wallpaper with latex. The paper had bubbled.

Remove loose stuff.
Oil prime areas to be mudded/patched (water in mud will further
bubbling of wallpaper).
Mudd and smooth
Prime everything with oil base.
Paint with latex.

Worked like a charm...whether it's suppose to or not.
