Ive recently had the bathroom renovated which included having the walls skimmed. After letting it dry (around 3 weeks) I've applied 2 matt emulsion mist coats and 2 top coats of bathroom paint. Two days later I noticed the paint edge by the door frame was lifting away, and with some gentle scraping it peeled right off. Its peeled away about 2-3 cm but the rest of the room seems ok. It doesn't seem to want to peel back further than 2-3cm so not sure if that area of plaster just wasn't fully dry?! Its peeled right back to plaster so clearly the must coat hasn't taken in that area. What is the correct way to fix this? The bathroom paint is soft sheen and tin says it can be diluted for fresh plaster. Do I remist the affect area or apply something else instead/ as well? any help or reasons why it happened appreciated. The white in the picture is the door frame.
