Mildew grows mainly in damp, humid, or moist areas of your home, but the best form of prevention is using mildew-resistant paint. Keeping mold away once it becomes prevalent in your home is harder than actually preventing it in the first place. It can mean having to replace entire walls or ceilings, so preventing, rather than curing, is a better way to keep mold at bay.
Clean the Affected Area
If you have an area in your home which is becoming infected by the growth of mold, the best thing to do first of all is to address growth before it gets too out of hand. Mold and mildew have potentially dangerous spores that can cause health issues, so clean the area thoroughly with a mold or mildew fighting cleaner. Use soft cloths or soft-bristled brushes instead of hard brooms or abrasives to reduce the spores that can become airborne and create a health hazard. Remember to wipe rather than a brush.
Once you have cleaned the area thoroughly, allow it to dry with good ventilation and fresh air. If you can use a dehumidifier to dry out the air and moisture in the atmosphere, you will give yourself an advantage in the fight and a fresh base to start from.
Lower parts of the walls in bathrooms, basements, or mudrooms tend to be breeding areas for mold and mildew and also the tops of corners and edges near the ceiling. Use soft bristle paint brushes or foam brushes to brush a coat of mildew-resistant primer as your primary source of protection. Let that coat dry before applying the first coat of paint.
Paint Moisture-prone Areas
Use mildew-resistant paint on the lower parts of walls and floors in basement areas. This will also help if you live in a flood-prone area, as even an inch of floodwater can be difficult to remove and the damp that seeps into the walls and floor will cause mold and mildew. Paint the area with foam or soft-bristled brush and lay on at least two coats. The chemicals in the paint will not only kill and disguise any old mildew stains but it will also prevent any potentially new growths from occurring.
Pay Special Attention to Bathrooms
Bathrooms especially are very prone to mildew. If your bathroom does not have an extractor fan or window then you are without a doubt going to be in for a battle with mildew and mold. The high humidity area has no way to breathe, so if possible, use mildew and mold-resistant paint on the walls and ceiling to keep the risk of growth to a minimum. Shower areas are not so easy to keep under control, but if your shower area has painted walls or a plastic, all-in-one shower fitting, you may get away with just painting the ceiling. However, the mold and mildew will still need to be kept off of the unit itself by using appropriate cleaners.
