Skimmed plaster walls with joint compound primed with Kiltz not adhering
We have a 1942 house with plaster walls. To repair them, we skimmed with a joint compound. Then to prep for painting with primed with Kiltz latex. The Kiltz is adhering to the wood trim, but is coming off on the walls. What the heck do we do?

Welcome to the forums!
I never use that primer. When stain hiding is needed, there are better choices [solvent based] otherwise I'll use one of the primers [or type of primer] recommended for the top coat to be used. Because I don't use latex kilz, I can't say from experience but kilz 2 has a reputation for having adhesion problems
Is the the joint compound coming off with the primer or just the kilz primer? Was the sanding dust removed from the walls prior to priming?

The jont compound is intact - just the Kiltz is peeling when tape was applied. Even switched to a low adhesive tape and it still happened. Yes, we clean the walls twice to eliminate dust, etc.
I believe Kiltz is the problem here. If a couple of more days doesn't resolve the problem, I guess we will have to lightly sand to remove as much of the Kiltz as possible without damaging the "mud" we have applied and start over with another primer...

Yep, sand off the Kilz and go with something from Zinnser.
Original Kilz (oil based) is an ok primer for sealing a surface but the latex stuff you used has a poor reputation.

Water Based Kilz is your problem
Yes,
I've had similar problems with Kilz waterborne drying either to slowly or drying out to quickly to hold to drywall over a vapor barrier or plaster.
Good Luck I would change to a Cover stain primer and simply paint over the effected areas.
