Mainly, it doesn't use the traditional paper facing. Mold-resistant drywall typically comes in two forms – either with a gypsum core and fiberglass facing or with gypsum material consistent throughout the drywall (also known as homogeneous).
Adequate ventilation, proper drainage, solid surfaces, and proper cleaning are essential. If you do replace standard drywall in your bathroom, use a paperless board like DensArmor or USG Glass-Mat. Also, use National Gypsum's mold resistant joint compound. Mold will grow on standard drywall mud.
Maintaining proper humidity levels is key to preventing mold growth. Use a dehumidifier in damp areas to keep humidity between 30% and 50%. You should also ensure proper ventilation in bathrooms, kitchens, and laundry rooms, and use exhaust fans when cooking or showering to remove excess moisture.
mold resistant drywall doesnt stop mold from growing, it just slows it down. if there is a leak and no airflow mold will always grow. so do with that information whatever makes you feel better.
Blue Board Drywall
Unlike the green board drywall, blue board works great in bathroom areas or places that get in contact with water. It is perfect for wet areas because it has great mold and water resistance qualities.
Areas that experience high moisture levels or excessive humidity due to appliances, fixtures, or environmental conditions can benefit from mold-resistant drywall. Consider using mold-resistant drywall in kitchens, bathrooms, laundry rooms, mudrooms, and similar spaces where moisture is constantly present.
The Ideal Drywall Alternative for Basements
Trusscore products, made from PVC, are mold- and mildew-resistant panels for basement walls and ceilings. They reflect light, they shed water, and they won't expand or swell. And Trusscore products clean up with a simple wipe.
Additionally, there are instances when even mold and moisture resistant drywall can be compromised. If your home is flooded, the power of the water could seep through the drywall and get it wet. If there is an unfixed leak that is left to flow over time, the water can start to break down almost any material.
phasing out greenboard
This relatively new addition to the drywall market is gradually replacing green board because it's suited to the same tasks but even more water- and moisture-resistant than green board. Paperless drywall consists of a water-resistant gypsum core and a fiberglass (rather than paper) backing.
Discover Trusscore PVC wall panels – the perfect waterproof drywall alternative for your garage, basement, car wash, or any wet environment. 🌧️ 100% Water-Resistant Prevents mold and mildew damage.
Antimicrobial sprays like Microban can stop mold and mildew in their tracks, while also inhibiting the growth of other harmful bacteria.
Damaging Effects of Water behind Drywall
Mold can only grow where there is enough water to support it. This means that when you have mold growing behind drywall, you have excess water behind your wall.
Homeowners insurance doesn't usually cover mold damage or removal unless it's the result of a covered peril. If the mold in your residence was caused by something sudden or accidental, such as a bursting pipe or some other covered incident on your policy, you may be protected.
For this reason, we highly recommend Suretherm Anti-Condensation Paint. Suretherm helps prevent the route cause of the problem - the moisture! Suretherm Anti Condensation Paint is an internal water-based emulsion that is specifically designed to help deal with internal mould and damp caused by condensation.
What's the difference between PURPLE drywall and traditional green drywall? Traditional green drywall (also known as greenboard) is only moisture-resistant. PURPLE drywall, manufactured only by Gold Bond Building Products, is superior because it offers moisture, mold and mildew resistance.
If you don't replace water-damaged, moldy drywall, it could end up compromising the structure of your home. It's also a health hazard, and in some cases, the only way to get rid of toxic black mold on drywall is to remove the affected panels completely.
Nor will it prevent mold in the case of flooding, when water saturates the drywall and the organic wood framing behind it. But in rooms that experience frequent humidity and are often subject to mold and mildew, such as bathrooms or basements, mold-resistant drywall is a good choice.
How to Waterproof Drywall. To prevent costly and time-consuming repairs from water damage and improve the water resistance of drywall, there are two options you can choose from: You can apply a waterproofing primer to standard drywall, or you can buy a water-resistant version of drywall from a local retailer.
Green Board Drywall – An excellent choice for kitchens, bathrooms, basements, and attics, green board drywall is mold resistant and typically comes in 1/2-inch or 5/8-inch thicknesses. A thick layer of green paper is applied to the surface of the gypsum, and a wax coating is applied over the paper.
The green and purple board are more fro moisture and mold resistances, the blue board are specifically engineered for veneer plaster such as a imperial base coat plaster which don't need glueing or bonding agents. I apply a bonding agent over all boards except for the blue board.
Alternaria. This mold is black, brown, or purple in color and has a musty odor. It occurs mostly on organic materials such as decaying vegetation, straw, wet wallpaper, and attic insulation that becomes damp from condensation or leaks like those around windows where there are water stains on the drywall ceiling below.
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.
Add two cups of hot water, 2 tablespoons of borax, and ¼ cup of vinegar together in a bowl. Combine the ingredients, and pour the mixture into the spray bottle. Spray a generous amount onto the moldy sections of the wall. Grab your brush to scrub the affected areas well, and then wipe it clean.
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%.
