Paint peeling from plaster.

[DeanInEssex]

Evening all. I had the kitchen re plastered two years ago. Let it cure for six months then watered down mist coat. No probs. Kitchen fitter put cupboard up but I didn't like it so removed and holes filled. Think he used tetrion. Emulsioned it today and all fine except one small six inch section above the tetrion where the paint has lifted as in the pic. Used dulux trade white. I'm thinking some kind of contamination but it's just a guess.
The paint has lifted completely not just the top coat. When I was rolling it cracked and just peeled back to bare plaster if that makes sense. The rest of the kitchen is bang on just that small section.
Any ideas please and thank you.

It's normally down to not putting on a 'mist' coat to begin with, but you say that you did that? How loose was you mist coat?
In my experience, dampness can also lead to this problem. Even if it looks dry, it isn't always dry. I'd treat it by bursting any loose peel away, sand down, apply an oil based primer, flush fill if required, touch the dry filler with the oil primer again and then try to coat with emulsion as normal. That (eventually) worked for me after trying other things first.
