as my name says, im not plaster so i got someone to do the job for me.
i took old plaster out all way back to brick walls. plasterer applied hardwall coat left it to set few hours before skimming. he used pva.
after few days cracks appearing only in places where wooden joists are located (above windows and doors).
before plastering we have installed metal mesh everywhere wood was found, so no plaster was applied direct on wood.
1. why these cracks appearing now ?
2. and are they only on skim coat or likely to be all way back to hardwall coat ?
3. any thought of best method to fix ?
