Recently I've been refinishing the walls in my bathroom - I peeled the
gloss-finish wallpaper off the greenboard, which was quite easy but
pulled the paper surface off the board in a few spots. I've been
skimming a thin coat of joint compound over the walls to even out
stuck-on adhesive, low spots, joints, etc., and where the paper was
pulled off the moisture from the compound seeps in and ripples the
paper surface under the new finish. I've been trying to prep these
ripped spots with paper drywall tape or drywall primer, without much
luck. Anyone know what I should be doing (or if what I'm doing I'm not
doing right)?

I've also noted the compound sets up very quickly on this job, probably
due to the thin application. I can get in maybe three swipes before it
gets unworkable. Any way to extend the work time?

The only way I've found is to take a box cutter and cut the delaminated
paper away. For example, if you have a quarter sized area that is bubbling,
take your knife and cut out the paper for a 1/2 inch all the way around the
bubble. Go ahead and cut down into the limestone and dig a little of that
out too. You need to remove all of the delaminated (bubbling) paper.

This can be a long process. You fill, find a bubble, cut it out, and fill
some more.

I wouldn't try. Just get a thin coat on the wall as best you can, let it
dry, and then do it again.

Different kinds of compound dry faster or slower. However you may try
spraying a little water on the wall before you patch. No standing water,
just some to help bring the moisture content of the wall up a bit so it does
not wick so much out of the compound you are using.
