Install Mold Resistant Drywall for healthier living
I am often asked about “mold resistant drywall”. Greenboard is used in bathrooms, basements, and other areas where the drywall may be subjected to damp conditions, humidity, and the occasional minor splashes of water. It is the same as regular drywall except for its paper covering resists water (but is not water-proof). Using greenboard drywall in a wet location like a shower stall is a recipe for disaster as severe mold growth will occur. Greenboard is intended for Damp, but Not Wet, applications while it’s paper covering is water-resistant it’s not waterproof. Not only that, but the gypsum core is not suitable for wet applications. Many contractors who work on the cheap use it under tile and it’s a disaster. A cement-based board like Wonderboard is suitable for tile-covered wet applications like showers Greenboard drywall is used in damp areas. Contrary to what some people may think, it is not used in highly wet applications such as shower stalls.
As an alternative, paperless drywall has fiberglass facing on the gypsum sheets. It also is not guaranteed to be 100-percent mold-proof, but it eliminates a major food source for mold. Mold only grows on what it can eat, and its biggest food source in a home is the paper covering on the sheetrock. I suggest that this product is used in any chronically damp area of a home that you want sheetrock in, such as a garage or the closet that stores the well tank. Prevention of mold, is a lot easier than removal of mold.
