Problem painting a skimmed wall.

[pz8d3r]

I'm having a problem painting a wall that was skimmed about 2 months ago.

I used a general purpose primer but when it dried it cracked in areas and peeled away in thin flakes. I've removed the flakes and sanded those areas back to a clean surface and repainted with a primer that specifically mentions plaster, but the problem keeps occuring at the junction with the earlier primer.

Any ideas?

what was the earlier primer you used? almost sounds like it was an oil based one from the problem you described

Yep....why did you use an oil based primer on new plaster? was it an exterior? or was you intending to finish the wall with an oil paint?

If the wall was skimmed two months ago, it should have dried out pretty much by now, especially if it's only skimmed. Skim coats only need days to dry out. All it would have needed is a wash coat of emulsion/water followed by a couple of coats of emulsion.
