Q: Does Painting Over Mold Kill It
Use the strongest bathroom fan you can find to prevent mold from growing. Test the airflow of a fan by holding up a tissue if the suction from the fan causes the tissue to stick, the fan is strong enough to clear humid air.
A: Unfortunately, no. There are coatings that claim to kill mold, but you still need to clean the mold off the surface beforehand by killing the organism and mold spores with a mold-killing detergent. Its feasible that mold can grow underneath paint coatings and put the health of your family at risk, especially if the mold is inside your home. So unfortunately, no, painting over mold does not kill it.

Landlord Responsibilities For Mold
Landlord responsibilities for mold are not explicitly outlined in building codes, ordinances, statutes, or regulations. However, landlords can still be held accountable for mold problems, even if the law isnt mold-specific. Only a few states, including California, Indiana, Maryland, New Jersey, and Texas, and a few cities, including New York and San Francisco, have regulations for mold and indoor air quality. You should check your state laws and the EPA website for any mold standards or guidelines.
Remember that it is a landlords responsibility to provide a habitable living space to their tenants. Depending on the situation, if mold is present in the rental, the tenant may be able to withhold rent or file a lawsuit. For instance, if you fail to repair a leak and mold begins to grow in the soaked area, any health problem caused by it would be your fault. Some landlords choose to include a mold clause in their lease that relieves them from any liability related to mold growth. A smart landlord will work to prevent mold from growing and inform their tenants of the hazard. If your tenant notices mold, make sure to act on it immediately and use an effective mold cleaner. Improving your indoor air quality and maintaining it, with products like the Moso Bag, will ensure that your property is always in the best condition. If you take the right steps now, you can avoid having to pay for mold remediation services.

Mold Killing: How To Fight Mold In The Home
Mold is a top concern for indoor air quality and remains a common problem in homes across the country. Mold and mildew are both types of fungi and are similar in many ways. From causing musty smells to serious allergic reactions, indoor mold and mildew can be a pesky nuisance or a real health hazard. EHT offers a few handy tips to help fight these problems around your house.
Spot the Spores
Mold is typically fuzzy in appearance and can be seen in many colors, including blue, green, yellow, brown, gray, black or white. Mold can cause structural damage to homes over time and lead to health problems, including respiratory problems, migraines and more.
Mildew usually grows in a flat pattern and may appear either powdery or downy. Powdery mildew usually starts out white and may later turn yellow, brown or black. Downy mildew usually starts out yellow and later turns brown. Like mold, it can also cause respiratory problems and allergic reactions.
Look for visible signs of mold and mildew around your home. Musty odors can be a sign of mold growth, but such a smell may also indicate mice infestation. Microfungal growth of mold and mildew can sometimes be difficult to see. One trick is to shine a flashlight nearly parallel to the lower portion of wall or leg of furniture. Look for fuzzy white, pale yellow or blue-green spots. These are likely mold colonies, and when disturbed these spores can become airborne.
