My best friendy, debs, her fella is plastering a wall that needs redoing. The plaster looks still wet after 24 hours how long will it take to dry out and can we put paint straight on top please?

Is the plaster a skim coat over plasterboard???? if so a couple of weeks will be fine as long as the plaster is a uniform pink when dry.

You must ensure any wet/damp patches are fully dry.
