Mold in the Home
Mold is everywhere in the environment. Some molds, yeast for example, are beneficial. Other molds can destroy surfaces on which they grow. In interior spaces mold can be kept to a minimum by ridding the space of conditions favorable to the mold spores. Other than allergic reactions, mold usually is not harmful to a healthy person, but care should be taken if there is any question about your safety and health. Small areas of mold should be safe to clean. If the mold has covered a large area or was caused by a septic or sewage problem, a professional should be consulted. Mold can be prevented if you will:
- Regulate the humidity in the space. The ideal relative humidity is between 30 and 50 percent.
- Check for and repair leaky faucets and pipes.
- Periodically inspect inside of closets and behind all furniture for signs of mold growth.
- Keep your carpet dry. If carpet becomes wet, immediately raise it and the pad up, allow them to dry and then reinstall the carpet. Use fans to speed up the process.
- Increase ventilation and air movement by opening windows and using fans.
Do not paint over actively growing mold. It should be cleaned and the surface allowed to completely dry before painting. Sometimes mold will penetrate drywall enough that it will have to be replaced. To clean small areas of mold keep these things in mind:
- Wear a properly fitting N-95 respirator mask.
- Wear chemical resistant gloves and non-vented eye protection.
- Use chlorine bleach carefully, taking all precautions pertaining to its use.
- Rinse the surface with clean water and allow to dry before painting.
Mold spores will multiply when the conditions are favorable. They will thrive in areas of high humidity or moisture, dark areas, and in spaces lacking ventilation and air movement. Keep your home beautiful, healthy and mold free by keeping these factors to a minimum.
