Is drywall mold and moisture resistant?

Also called &#;greenboard&#;, mold-and-mildew-resistant 1/2-in. drywall is a somewhat different animal. Manu­facturers use various methods to eliminate or treat the paper that covers the gypsum core. Getting rid of the organic paper food source was supposed to keep mold and mildew from growing. Builders used to install it in wet and damp locations, placing it behind tile in shower and bath enclosures. Those enclosures have already been or soon will be replaced as the greenboard fails.

Pro Tip: Although you&#;ll still find greenboard at home centers, we advise against using it, especially for tile backing in wet areas. There are much better alternatives for tile in wet locations&#;cement board, for one.

Construction Pro Tips

Half-inch drywall

1/2-in. drywall is the best choice for most walls and some ceilings. There are standard and lightweight versions. Lightweight is stronger and weighs 25 percent less.

Pro Tip: Spend a few extra bucks and get &#;ultralight&#; or &#;lightweight&#; drywall. It is easier to handle and stiffer, so it can cover ceilings that have joists spaced at 24 in. That&#;s why some stores no longer even carry standard 1/2-in. drywall. Get to know about different types of drywall.

3/8-in. and ¼-in. drywall

If you&#;re doing repairs in a house that was built in the &#;50s or &#;60s, you may very well have 3/8-in. drywall. You&#;ll want to match that thickness to patch an existing wall. Measure the existing drywall or take off a switch plate cover to find out.

Pro Tip: Unless you&#;re matching existing drywall, there&#;s rarely a good reason to use 3/8-in. drywall. Remember that window and doorjambs are generally sized to be flush with 1/2-in. drywall.

1/4-in. drywall is a very thin material so it is mostly used to cover bad walls: cracked plaster or unremovable wallpaper, for example. Because it is more flexible, it is also sometimes used on arches or applied in two layers on curved walls. Specialty stores carry drywall that&#;s super bendable&#;flexible enough to drywall the inside of a barrel!

Pro Tip: Screws don&#;t countersink well in 1/4-in. drywall, so construction adhesive is a better choice if you&#;re covering bad surfaces. Tack it in place with a few nails until the adhesive sets.
