Many homeowners or renters will eventually have to deal with mold in their lifetimes. Mold grows where there is little light, but plenty of moisture, making bathrooms, basements, cellars, north-facing outdoor spaces, etc. very likely to develop mold growth. External walls, sidewalks, and even furniture can develop mold. If you have a mold and/or mildew infestation, either inside or outside, there are some steps that you can take in order to prevent that mold from spreading and to prevent it from taking a toll on the health of anyone who comes into contact with it.
How to Remove Mold and Mildew from Painted Surfaces
If you see a colony of mold growing on a painted service, bleach is a great tool to remove it. Mixing a solution of one part bleach to one part water and then spraying it onto the mold colony can neutralize the issue. First, spray the colony with clean, warm water, and once it is thoroughly damp, spray it with the solution of water and bleach. After it is allowed to sit for fifteen minutes, the mold should be brown, indicating that it is dead.
Another mixture you could try is a one part bleach to three parts water solution, and let it soak into the mold colony for twenty minutes. A gallon of water, mixed with a fourth cup of trisodium phosphate is also a good mixture to kill mold.
Once the colony has been thoroughly soaked and has begun to change color, it is time to take a brush to it. Find one with stiff bristles and clean the mold or mildew away by scrubbing it with the brush. It is not recommended that you use a power washer, simply because power washers can damage the surface underneath the colony.
Throughout this process, be sure to wear eye and hand protection. Once the mold is removed from the surface, use clean water to thoroughly rinse the area and then let it dry for at least a day. To prevent further growth, cover the area in a paint that is mold or mildew resistant and keep the area as clean and dry as possible. Oil-based primers with stain-blocking additives can also help to prevent the return of a mold colony.
