This is just in one area, everywhere else seems ok, same materials, too.
and I KNOW there is no moisture leaking etc.
One small area of resurfacing, I'm having difficulty getting the paint to
adhere to the skim coat. Multiple coats and months later snag and you can
peel off a thick sheet the size of a sheet of paper! I've done multiple
things to get paint to stick here, like even using a tack rag to wipe over
the surface first, going through several tack rages, too. I swear I've
seen this effect on multiple skim coats too where a layer simply peels off
Is the problem waiting too long before painting, or resurfacing, or not
long enough? I'm about ready to tear the whole !$#@!@$# thing out and
start over, but that is not a viable option this time.
Any ideas as to how to make the paint adhere? coat with glue? what?

other areas -- no problems.
First, never use Glidden paint. It's junk. I used
their oil base exterior solid house stain once, many
years ago. Their own specsheet said it was 30%
water! The stain went on thick but immediately
settled, as though it were pumped with air. The
result was very poor coverage. Apparently they
were watering it down by about half, adding an
emulsifier, then adding a thickener to make it seem
normal. The price was right -- $10 vs $25 for Benjamin
Moore. But paint that's no good is no bargain at
It's worth buying real paint. (Pratt and Lambert. Sherwin
Williams. Benjamin Moore has been downgraded but
still isn't bad. A lot of people like California. I haven't
tried it enough to know.)
For the current case, it sounds like you got
something onto the compound. I'd try skim
coating again and/or using a wallboard primer
thing out and

What's under the skim coat??? Sounds like perhaps something underneath
is volatile and outgassing or the like.
What about primer?
Despite the other poster's complaint re: Glidden (and not he was
complaining of a stain and not a paint, anyway), I've used their
products quite satisfactorily and believe they're in the same class as
most others as long as you compare roughly equivalent price-point products.
Depending on the answer to the previous queries, you _might_ have some
luck with a shield coat of cut shellac as a barrier before priming.

Whatever Glidden is or isn't, I agree I don't think it's the source

it's possible the mud was contaminated with something. I've never

I prime new work, but not patches. I just spot-prime
those with the finish paint before I start rolling the wall.
Many paints are now sold as self-priming for use on plaster
or compound. Personally I find the "self-priming" idea
questionable, but I've never actually seen wall paint peel
because it wasn't primed first. The main function of
priming on drywall is to provide an even, consistent
surface for the topcoat to go over, which gives better
coverage and consistency of sheen.
Priming *might* help now, but only because it might
get through whatever is on the compound.
this paint is 'self-prime' but EVERYWHERE else works great! Often I only
use a paper towel to knock the 'dust' off and paint right over, and paint
Same method on this spot, didn't work! ok, try again, but this time be

Problem is, you've still not addressed any of the ?? raised regarding
what's the actual details of the situation the fill/skim is covering;
clearly if you used the same material here as in other locations there's
something going on at that location that, unless cured, probably won't
make any difference if repeat the same process yet again (the old saw of
"the definition of insanity is..." comes to mind :) ).
There's _SOMETHING_ cause the lack of adhesion but what the cure is is
completely impossible to guess unless and until can get at least some
idea of what that causative agent might be.
If it were mine, likely I'd just cut the offending area out back to next
two adjacent studs and patch in a new piece of drywall and refinish and
quit trying to salvage a small spot.
I'd REALLY ask at a REAL paint store. That said, PVA is used as a
primer for a lot of stuff.....when I did crafts with plaster molded
stuff, watered-down Elmer's Glue was used for primer. Worked great.
PVA comes in gallons, which I have used to fasten linen to wood panels
(like the old masters did) for oil painting.

One thing you can try, and which will probably work, is to paint over
the joint compound in that area with diluted white wood glue.
Basically, you mix what wood glue into water, and use that to paint over
the joint compound in your problem area. The dry joint compound will
suck in the liquid, and the liquid will glue all the gypsum particles
together as the glue dries. There's no hard and fast rule as to how
much glue to mix with how much water. Basically, you want to solution
to be thin enough to be sucked into the joint compound by capillary
pressure. If you have too much glue, the solution will be too viscous
to do that. So, perhaps mix up a fair bit of quite dilute glue, and
apply multiple coats. That way, with each coat you introduce more glue
into the problematic joint compound, gradually making it harder and more
But, never ever paint directly over dried white wood glue because the
moisture in the new paint or primer will re-emulsify the glue causing
the joint compound to loosen up, and you'll have a mess on your hands.
So, after painting the dilute glue on and allowing it to dry overnight,
apply a skim coat of joint compound over that area (and after allowing
that skim coat to dry) THEN paint.
Or, at least that's the way I'd proceed if you don't want to scrape off
the existing joint compound and start over.

Interesting problem. I had a very similar issue with Glidden paint that a friend purchased at Wal-Mart. It actually lifted *old* paint off of joint compound. I blamed the last painter for not letting the compound completely set, but now I'm not so sure.
That's EXACTLY the answer I was thinking in terms of, except I
forgot/missed about not applying paint over the glue base! I never
thought of another skim coat to 'passify' the glue's surface.
Plus, multiple coats of glue from watery to thicker sound right, too.
Interesting. I have an area down a gallery hallway that has a patch like
that! The original Dunn-Edwards was sprayed on and adheres well everywhere
but a small patch along a doorway. As I painted more Dunn-Edwards over the
area, the stuff underneath started to roll up?! I simply stripped the
area, reskim coated, and painted with no further problems.
Now you have ME wondering.
Note, this is Dunn Edwards paint this time. [from memory the base is
versaflat, or such]
Just a light spray of solvent based paint does the job much more
easily. After doing some minor repairs and then wanting to repaint the
wall, I found the patches bubled up as soon as I applied the latex
based primer or top-coat. If I let the first coat dry the bubble would
go back down and almost dissapear, but the next coat raised the
blister again. I grabbed a can of automotive touchup paint I had left
over from the old Corolla and gave the repaired spot a light coat -
after a few minutes it was dry and I put a coat of latex over it
without any sign of a blister - and no problem with the paint sticking
or covering. Spray automotive primer in light grey would do the job
just fine as well.
