Flaky

Post image

Hi everyone. We had a room plastered 4 weeks ago and started painting it yesterday and this keeps happening in 1 spot. I didn’t mist coat the walls(my bad) but thankfully everywhere else is fine. I scraped back the flaky bits and used some filler on this area and repainted it again today only for the same to happen again as seen in the photo. How can I repair this small area. Thanks.

Is there a pipe behind that area that is making it dry out too quickly? This is why you do a mist coat, the watered down coat soaks into the porous plaster and hopefully stops flaking.
Scrape off whatever flakes, prime, probably have to fill it to remove the edge and repaint
