Mold is one of the most resilient organisms around and performs some essential functions such as breaking down organic matter. When mold gets into the home it can mean health problems and an unpleasant aesthetic appearance. Mold prevention sprays are one tool the homeowner has to reduce this often dangerous fungus. However, mold prevention sprays are just one part of a comprehensive mold remediation plan.
Mold prevention sprays either reduce mold indirectly by preventing moisture from building up on materials, or kill mold directly by use of a fungicide--such as paradichlorobenzene--that kills the actual mold spores, according to the University of Missouri Extension's home maintenance website. Both these may be necessary to provide the greatest amount of mold protection.
A water-resistant mold prevention spray functions by reducing the moisture essential for the growth of the fungus that causes mold and mildew, reports the University of Missouri Extension. Fungicidal sprays destroy the structure of mold and stay on the surface of the material to prevent further mold growth. Some germicides and water-repellents may also have fungicidal properties.
Mold prevention sprays can alleviate some of the health risks caused by mold growth. Mold spores travel in the air and enter the lungs, resulting in respiratory problems or increasing the symptoms of allergies, such as a runny nose and wheezing, reports the Georgia Division of Public Health. Mold can sometimes produce toxic chemicals.
Most mold prevention sprays use chemicals that can cause serious illness when breathed in, according to University of Missouri Extension. In addition, do not use paradichlorobenzene on plastic materials, only use on metal or wood. Never spray a mold or mildew fungicide near or on a open flame as most mold removal chemicals are flammable.
Do not just rely on mold prevention sprays to handle any fungal problems. Reduce moisture in the air with a dehumidifier. Look for leaks around the house than might collect pools of water. Dry out any clothes that become damp or soiled. Wring out shower curtains instead of letting them stick to the bathtub.
