Had this before. If the walls ain't been mist coated the new paint just sits on the wall and is not properly bonded cos it doesn't 'soak' into the wall. U can literally peel the paint off with a paper scraper. Surprising how many 'decorators ' (lol) don't understand this

Mist coat is applied with vinyl free contract matt emulsion, can even be applied before fresh plaster has fully dried as it allows any moisture to travel through and out of the paint work
