Editor's Review: New Antimold Drywall, Same Green Color

review date: January 1, 2008

United States Gypsum introduced green-faced, moisture-resistant drywall back in 1963, and "green board" began its long run as the preferred wallboard in bathrooms, laundry rooms, and basements. In 2003, USG introduced a companion product called Humitek, designed specifically to resist mold. In 2007, USG stopped producing both and introduced its latest weapon: Mold Tough drywall.

The new panels have the same green color as the old stuff, but with a perfect score on the ASTM D3273 mold-resistance test, they are better at their job. Plus, a paper facing means you won’t have to skim-coat the surface of the wall as you do with many competitive fiberglass-faced moisture-resistant panels. Mold Tough can also be attached to wall and ceiling framing spaced 16 in. on center or wider; older versions tended to sag if spacing was that wide.

Mold Tough is available in 1/2-in.,5/8-in.,3/4-in., and 1-in. thicknesses, with 1/2-in. fire-rated panels in both type C and type X. Although this product resists mold, it’s not a substitute for the cementboard panels used in wet areas such as tub surrounds and tiled showers.
