you must use a good quality paint , not cheap stuff !

what would you consider to be good quality? I used one of the ranges from B&Q (I think it might have been called colours or something) and the time before it was crown or dulux or something like that - whichever one you can get mixed up to get the correct colour in the shop.

A mist coat (highly thinned) must be used on all new plaster or you can have problems, vinyl is a definite NO also.

If it was vinyl, how can it be remedied?

If it is vinyl you would be better to scrub the lot off using hot water! water based paints will disolve, hard work though...

By my own logic (which is [STRIKE]often[/STRIKE] usually flawed, surely if paint won't stick to the wall then neither would wallpaper paste? Genius I ain't though!

Eco-friendly, the house was newly built about 7 years ago and the paint on it wasn't matt but didn't look particularly shiny either. the band I painted on was a navy flat matt but this was only a few inches wide. the paint that went on top of the skimmed plaster 6 months ago was matt.

Something is telling me that whatever is on the wall is reacting to all the new paint you are putting on. By putting on lining paper you are avoiding contact with whatever it is that is making new paint flake.

I would be very concerned if the wall rejected the paste and lining paper and would probably advise getting the wall tested for moisture content.

I have just had a number of rooms plastered and was told to leave the plaster as long as I could before painting it with 70/30 paint/water which I then applied 3 times before painting with my preferred coloured paint. I left the walls around 1 month before painting.
