Not to freak anybody out or anything, but I happen to have noticed that someone found this blog this morning by googling the phrase "joint compound won't stick to walls." I followed up with google and discovered that the answer isn't really there. So, herewith (which seems to be my favorite word these days):
A Tip From Johnny:
Whoever you are, if you're still out there, Johnny says make sure you wash it first with a bleach solution (1/4 cup or so per gallon), let it dry completely, sand it well, then dust it off (a soft paintbrush will do the trick).
When you apply the joint compound, make sure you're using skim-thin coats. You'll have to do it, let it dry, then do it again at least twice, and maybe more if your walls are really bad. (Don't forget to sand in between -- but lightly, or you'll sand off all your hard work). If you try to make it cover in one coat then it will just fall off.
If you've already done all that, or if you do it now and it still falls off, leave a comment here and I'll ask him what to try next.
I'm about to embark on my first joint compounding experience any minute now, so--hey...
You don't think that was me, googling myself from the future, do you?
(Ooh, hey, PS -- Johnny reminds me that the above advice only goes for old walls, walls that have been painted at least once already. If you've got new, unblemished blueboard, for god's sake don't wash or sand it! And in that case, if it won't stick, then all he can think is that you're slathering it on too thick.)

PPS Johnny says if it STILL won't stick then the walls are probably greasy -- or sometimes a build-up of nicotine has the same effect -- in which case you want to wash with DirtEx (I just looked it up and discovered that it comes in a spray, but I've never known Johnny to use anything but the powder, and you can trust that if that's what he uses then there's a good reason).
Well, almost 15 years later here I am. We hired a dry-waller to scrape a popcorn ceiling and create a painted one. The popcorn was 24 years old. He did a great job but the plaster doesn't want to stick in the kitchen area above the island. The area above the sink was first so he scraped it back and added Kilz primer. It seemed to work until he had a fellow in to spray paint. This paint is apparently really thick and so goes on in one coat. By last night it was falling off in chunks over the kitchen island (not primed). The room has been really humid and very warm through the whole process due to large windows and wet plaster. Any ideas to fix the problem so that it immediately sticks and so that we don't have chunks falling throughout the area over the next ten years? Our guy is at a loss.
