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.

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]
