How to prevent bathroom mould forming

Once established, mould around a bath or shower can be hard to get rid of, but using these techniques for eliminating bathroom moisture can help keep it at bay.

No matter where you live, a high moisture level in your bathroom makes mold almost impossible to get rid of, no matter how much you clean. Eliminating bathroom dampness is the key to keeping mold from growing. To do that, follow these steps:
  • After a bath or a shower, squeegee water off the shower walls. That eliminates at least 75% of the moisture that supports mould and mildew growth.
  • Run your bathroom fan during your bath or shower and for 15-30 minutes after to flush out moisture. Or add a timer switch to make this step automatic.
  • If you have tiled walls or floor, seal the grout lines annually with a standard grout sealer to waterproof them.
To get rid of the current mold, scrub with detergent and water, then let the surface dry completely. Or use a solution of 10 percent bleach and 90 percent water (a stronger bleach solution will not give better results). Spray or brush on the solution, let it sit 10 minutes, then rinse it off and let dry.

If the fans aren’t clearing out most of the moisture in your bathrooms after five to 10 minutes, your fans may not be moving enough air. Fans are certified by the volume (m3/h, or litres per second) of air “extracted” from the room. To find the recommended fan capacity for your bathroom, simply multiply the bathroom square metreage by 1.1 (assuming an 2.4m ceiling; 3m high ceiling, multiply by 1.7).

Fan rating, type and location together ensuring adequate air flow can make it into the room all play a part in effective moisture control. Fans with an overrun timer that continue to operate for a set period, even after the lights are turned off are highly recommended.

Fan location is critical…  You can install the most powerful fan and find it’s ineffective in moisture elimination if the location of the fan doesn’t promote a circulation of air within the overal space of the room. Fans should be located in most cases furthest point from the door, to eliminate a ‘short-circuit’ of air flow between the fan and the door.

Tight fitting doors can prevent sufficient flow of air into the room, thus restricting the required amount of air to be exhausted from the room. A good test of this is to run the fan with the bathroom door closed, then open the door and see if the pitch of the noise of the fan changes. If it does, you may need to trim the door to incease the flow of inbound air.
