I always say leave the plaster to dry for at least a week before painting, if you can leave it for longer the better. Leave it to dry naturally and leave windows open if you are at home and not to put the heating on hoping to dry quicker this will result in the plaster to crack. Once it's dried apply 1 mist coat of water/emulsion the seal the fresh plaster.

Anything from a day to week or more. Once the plaster has dried it will be a uniform pink colour. Plaster on plasterboard will dry much quicker than plaster that has been applied to internal render, after damp proofing. Do not leave heating on to dry it quicker as this could cause shrinkage resulting in cracks in the plaster. Once fully dried apply a mist coat of water/emulsion paint to seal the fresh plaster.
