Water damage, whether by excessive rain or a plumbing leak, can be devastating to plaster walls and ceilings. Damp walls and ceilings can not only be the source of odour in your home, but can provide a perfect breeding ground for mould. You must dry the plaster as soon as possible to mitigate the propagation of mould spores. You can dry wet plaster walls and ceilings with the correct equipment and by following a straightforward procedure.

Shut off the circuit breaker that supplies electricity to the affected room. Even if no outlets or fixtures are close the damaged area, it is always best to ensure safety by shutting off the electrical current.
Locate and repair the source of the water. If there is a plumbing problem, call a professional plumber to make the repairs if you do not feel comfortable completing them yourself. Do likewise if the source of the water is a roofing problem.
Remove lighting fixtures that are located in the vicinity of a ceiling leak. Remove the outer cover, which usually is secured with thumb screws or snaps. Unscrew the light bulbs. Remove the screws that secure the fixture base to the electrical box in the ceiling. Untwist the wiring and pull down the fixture.
Move furniture away from water damaged walls to allow air flow to reach the damage.
Set up box fans to move air over water-damaged walls and adjustable oscillating fans to move air over water damaged ceilings. Open windows if the room has any and keep the fans on 24 hours a day until the plaster is completely dry.
