The chief innovation in mold-resistant drywall is the substitution of fiberglass mat for the paper facing used in traditional drywall. This way, moisture cannot adhere to the organic paper material, creating an attractive food source for mold.
Use a material other than paper for the outer layer on the drywall panels. This form of mold-resistant drywall typically uses fiberglass mesh instead of paper for the facing and backing. Because fiberglass is a non-organic material, mold has no food source necessary to colonize.
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.
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.
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.

The best way to dry wet drywall is to dry it from the inside out. This can be done by using a fan or a dehumidifier. Use a moisture meter to check the moisture levels. Once you have started drying the drywall, checking the moisture levels with a moisture meter is important.
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.
If you find mold on your drywall, you'll most likely need to get it replaced.

Green board is called that because the face side paper is sea-foam green. The color is only used as a means of identifying this particular type of drywall. What makes this type of drywall different is that it is moisture resistant. Its core is impregnated with water resistant materials.
mildew and mold will develop within 24-48 hours of water exposure. Even worse, it will continue to grow until steps are taken to eliminate the source of moisture, and effectively deal with the mold problem. Use the diagram on the facing page to assess the extent of mold in your home.

Steps you can take include using mold-resistant building materials and adhesives, insulating pipes to prevent cracks and leaks, and using an HVAC system with filters to catch or prevent mold spores from coming into the home. In order to inhibit mold growth, keep relative humidity below 65%.
If it is moldy, there has been enough water/moisture to ruin the drywall, even without the presence of the mold. The mold has warned you to replace it.
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.

While drywall repair is usually perfectly acceptable for cracks and holes up to and around six inches, a complete replacement is often required in the event of major disaster (ie.
Mold-resistant drywall works by creating an inhospitable environment for mold. Even if the surface of the drywall becomes damp due to moisture or humidity within the room, mold can't embed or feed on this type of drywall.
Dry the water damaged walls
Use high-efficiency blowers and dehumidifiers and open the windows and doors. Use fans to increase air flow behind walls and leave them running for at least two days so the studs and flooring can completely dry.
Use fans to move air around the damp walls. Also use dehumidifiers, which can help remove moisture from the air and walls. Professionals use tools like moisture meters, infrared imaging devices, dehumidifiers and heavy-duty fans. That ensures the walls are truly dry before further repair, painting or refinishing.
There are several options for moisture-resistant and moisture-proof drywall. 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.
