Possibly dust on the wall, from carpentry work or general building work, possibly plasterboard turned wrong way, possibly boards too dried out from heat .thats show business

plasters drying before its had chance to properly adhere to the substrate, think about it, its a wet material that will naturally shrink back/tighten up as the water draws out, if its drying out in a couple of hours its not getting enough time to bite into the board before all the lifes taken out of it:RpS_thumbup:

Still once its set it should be fine if its crazing when its not long been on problemo , how long has it been boarded ?

sounds like the boards were weather-beaten had they changed colour??? better to pva if they were

Hi Gemma
You hit the nail on the head, hot day wind blowing with no windows or doors the plaster dried to quick end of story.
