Preventing Mold Growth Nonporous materials such as plastic, metal, and glass are less likely to support mold growth but may do so if organic material is available in the dust or dirt coating these materials. Uncoated masonry is also less likely to support mold growth but may do so under special conditions.
Options such as porcelain tile, vinyl plank, and engineered wood are highly recommended by Buffalo Restoration for their durability and resistance to moisture. These materials are easy to clean and maintain, making them ideal for areas susceptible to water exposure.
Metal and plastic are top contenders for being highly resistant to mould because they do not hold moisture.
It is well known, however, that clean fabrics are less likely to mildew than soiled ones. Because most synthetic fibers, such as acrylic, polyester and nylon, are resistant to mildew, clean fabrics of these fibers will not support mold growth.
According to the CDC, mold is found both indoors and outdoors, and can grow on almost any substance when moisture is present.
While mold cannot get nutrients from inorganic material such as concrete, glass and metal, it can grow on the dirt present on these surfaces. Molds prefer damp or wet material. Some molds can get moisture from the air when the air is very damp, that is when the relative humidity is above 80%.
Hydrogen peroxide, commonly used to disinfect wounds, is active against a wide variety of micro-organisms including mold. It acts by releasing oxygen at a rapid rate, which kills mold by oxidizing the surface and breaking down proteins and DNA.
There are, however a number of surfaces where mold will not grow. Treated surfaces and drywall have been found to resist growth, even when wet.
Mould will even grow on synthetic fibres such as nylon and polyester if they are soiled or if they have finishes that provide food for the organism. Although mould spores are always present in the air, they are able to grow only if environmental conditions are suitable.
Mold-Resistant Insulation
Fiberglass insulation helps resist any water damage and mold growth. Fiberglass is resistant to mold by its nature, and some companies produce an added layer of protection by treating their products with an EPA-approved fungicide.
It is impossible to get rid of all mold and mold spores indoors; some mold spores will be found floating through the air and in house dust. The mold spores will not grow if moisture is not present. Indoor mold growth can and should be prevented or controlled by controlling moisture indoors.
Black mold grows where there is water damage such as shown in the photo. It grows on a range of materials, including drywall, wood, paper, carpet, painted walls, and cardboard.
When materials like drywall and insulation may have absorbed moisture and fostered mold growth, you may have to discard them because mold infestations can compromise their functionality and reduce their strength.
If you're already dealing with grout stains and shower mold, or if you're planning a bathroom remodel to prevent those problems, acrylic shower walls that look like tile are the ideal solution.
Polyester is a tough, versatile fabric. Polyester works well outside because it is resistant to stretching, abrasion, mold/mildew, and rot - it's also lightweight and flexible. Polyester can come vinyl-backed which adds to its inherent durability.
Extensive Mold Growth: Clothes that have been heavily affected by mold, particularly delicate or porous materials like silk or wool, may need to be discarded. Extensive mold can weaken fibers and cause irreversible damage.
Mold can only grow on plastic under certain conditions. If the plastic is clean and sanitized, mold will not be able to grow. However, if any grease, food residue, or dirty water gets left on the plastic for an extended period of time, it could get moldy. Take bathroom and pool toys like rubber ducks, for example.
Most yeasts and molds are heat-sensitive and destroyed by heat treatments at temperatures of 140-160°F (60-71°C).
Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash (dermatitis). Allergic reactions to mold are common. They can be immediate or delayed.
Mold prevention
DO put exhaust fans in kitchens and bathrooms. DO clean your bathrooms with bleach and other mold killing products. DO add mold inhibitors to wall and ceiling paints before application. DO inspect hoses, pipes and fittings to insure leaks won't cause dampness.
The only effective way to permanently get rid of mould problems is by reducing the build-up of moisture in your home.
Vinegar is natural and safe mild acid that can kill 82% of mold species. Plus it doesn't give off dangerous fumes like bleach. If you want to use vinegar to prevent mold growth on surfaces, spray vinegar on the surface and leave it. Repeat every few days to keep the surface mold-free.
