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.
The most popular way to waterproof your drywall is to use oil- or latex-based waterproofing primer. These primers are made by most paint manufacturers and are designed to prevent mold and mildew from growing on the surface of your drywall.
Drywall is essentially gypsum, with maybe some other additives, and then it has a paper face adhered to it with a water soluble glue. Both the paper and the glue are “mold food” if the drywall is constantly damp, or in unconditioned spaces.
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.
Using regular drywall in a basement is generally not recommended due to the potential for moisture and humidity issues. Here are some key points to consider:
The answer is actually twofold. We need to install a vapor barrier against the concrete foundation walls, and we also need to install an airtight vapor retarder behind the drywall, however, the wall must have the ability to dry if moisture happens to accumulate in the wall cavity.
One key difference between the two is that sheetrock is a brand name of drywall made by the United States Gypsum Corporation. Another difference lies in their production process; sheetrock has a slightly denser core than drywall due to the addition of a small amount of wood fiber to the gypsum core.
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.
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.
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.
If you find mold on your drywall, you'll most likely need to get it replaced.
Always hang PURPLE drywall with the purple side out, or facing into the room.
KILZ® MOLD & MILDEW† Primer is a water based primer-sealer-stainblocker that is specially designed for residential surfaces in high humidity, moisture and temperature environments such as kitchens, bathrooms, powder rooms and laundry rooms.
Acrylic-Based Waterproof Paint: This type of paint dries quickly and is flexible, making it a popular choice. However, it may require several coats to fully protect against moisture.
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.
PVC panels are impact-resistant, whereas drywall is prone to damage. Drywall contributes to landfill waste, decomposing into a pungent-smelling hydrogen sulfide gas. On the other hand, PVC panels are eco-friendly, have a low carbon footprint and can be recycled several times.
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.
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).
Green drywall, often referred to as greenboard, resists moisture to a lesser extent than purple and is ideal in rooms that have occasional moisture exposure, like laundry rooms.
Bleach & Water
Using a common household cleaner (like bleach) can be one of the best ways to deal with small areas of mold on your walls.
Moisture-and-mold resistant drywall is best used for interior walls, especially in areas like kitchens, bathrooms or basements. The best drywall boards for these areas have moisture-resistant cores that prevent water and moisture intrusion from seeping into the board itself.
Plaster veneer may also be applied to ordinary drywall, or over existing walls, but this requires "gluing" the existing wall surface by painting on a special adhesive compound, and then applying a thin layer of "base coat" plaster.
Hang the Ceiling First
This makes it much easier to manage and attach the panels since you will not have to fumble around with the screws, measuring tape, and so on. Screws for drywall lids should be placed no closer than 16” from the wall. This allows the drywall to have a bit of flexibility to prevent ceiling cracks.
