Green zip drywall




















According to ASTM C, after two hours of water immersion, the average water absorption for panels should not be more than 5-percent by weight. Caution should be taken when using greenboard and other water-resistant drywall panels for ceiling applications. Ceiling panels can sag when subjected to high humidity conditions or to textures and finishing materials that contain moisture. Cement-based backer boards Durock, Wonderboard, and Hardibacker are all mineral-based or cementitious materials.

Cement board is perfect for tile-covered wet applications like showers and tub surrounds. Wet or dry, such backer board provides a stable base for tiling. The organic element to drywall's paper is the chief reason why drywall may experience mold and mildew. Another advantage of the cement board is that it can be used as a base for tile flooring; drywall of any type can never be used for flooring applications.

One reason why builders may use greenboard for highly wet areas, though, is because it is faster and easier to install and less expensive on a square-foot basis. It is best to use greenboard or other water-resistant drywall in the large areas of bathrooms, kitchens, and other areas where the drywall may be subjected to lightly damp conditions, humidity, and the occasional minor splashes of water.

Using greenboard drywall in a highly wet location is possible but cementitious materials are a better product for that location. At the least, severe mold growth will occur with drywall. Sag and outright failure may occur when the drywall has been subjected to an abundance of water. Also consider a drywall product that has a fiberglass coating instead of paper. It is rated higher than "greenboard" in moisture and mold resistance. Actively scan device characteristics for identification.
