Was the plaster fully dry? Any picture of this? All i can think of is that its not been dry and is leaving a damp area of paint.

hi, we have just done the very some thing which is why i decided to log on for help!!!!!!!!!!!! We too did not prime the newly plastered wells in the extension and painted straight on with normal white paint on all walls an ceilings. The plan was to then paint over 2 to 3 coats for the finished look on the ceiling. Not attempted the walls yet. As we are rolling on the paint the pervious layers of paint are peeling off into the roller bringing all the paint layers with it, creating a void in the paint making patches too. We too feel gutted and are devistated that we may now have ploblems forever. Our beautiful kitchen/dinner may now be ruined because stupidly time and cost was playing a big part. Shot ourselves in the foot there i think! Any solutions at all, are welcome. thanks C

Hi happyhour, you needed to mist coat them first. This is why the paint is peeling off. You will probably be better off scraping the first layer off, it should come off fairly easily as it doesn't sound like it has adhered properly. If you put the second coat on the bare patches without mist coating which it sounds like you have that will probably peel off too. Then you will have your nice new ceiling again. Then sand off any rough bits. After this give the ceiling and walls a mist coat or two, this is a coat of watered down emulsion around 25- 50% water to paint. This will soak into the plaster, seal it and will stop further coats of emulsion from peeling. After doing this give them two further coats of emulsion in in the finish colour. Good luck.
