ToughRock® Mold-Guard™ Gypsum Board
ToughRock® Mold-Guard™ gypsum board is designed for use in interior wall and ceiling drywall applications. Featuring 100% recycled, green treated face paper and a moisture-resistant core, this wallboard provides extra protection against mold and mildew compared to traditional paper-faced gypsum wallboard products in high humidity areas such as kitchens, bathrooms, basements and laundry rooms (not for use in wet areas*).
No special tools are needed. The board scores and snaps easily. With proper surface preparation, it will accommodate a variety of decorative treatments such as paint and wallpaper.
ToughRock Mold-Guard Gypsum Board has a noncombustible (as described and tested in accordance with ASTM E 136), dimensionally stable gypsum core. It has 100% recycled paper coverings on the face, back and long edges; with a green face paper. When tested, as manufactured, in accordance with ASTM D 3273 ("Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber"), ToughRock Mold-Guard Gypsum Board has scored a 10**, the highest level of performance for mold resistance under the ASTM D 3273 test method.
These products are GREENGUARD Indoor Air Quality (IAQ) Certified® and GREENGUARD Children & Schoolssm Certified for low emissions of volatile organic compounds (VOCs).

Q:
Can ToughRock® Mold-Guard™ Gypsum Board be used in wet areas?
A:
ToughRock® Mold-Guard™ is manufactured to meet ASTM C 1396 section 7 for moisture resistant gypsum board. If your local code allows for the use of ASTM C 1396 section 7 in wet areas then ToughRock Mold-Guard may be used in this application.
Q:
Can ToughRock® Mold-Guard™ Gypsum Board be used in pre-rock conditions?
A:
While ToughRock® Mold-Guard™ is a moisture and mold resistant product, it is not recommended or warranted for exposure to the elements. We would recommend DensArmor Plus® Interior Panels for pre-rock conditions.
Q:
What should we do if the gypsum board gets wet?
A:
According to the Gypsum Association publication GA-231, gypsum board should not
be allowed to get wet; it should be covered if stored outside. However, there are
situations where the board could get wet in transportation/storage or installed
in-place. If the board gets wet in an installed in-place situation, first remove
the sources of moisture. Lay the board on a flat surface and allow it to dry out
thoroughly. Once the board is dry, examine it for paper-to-core bond failure, mold
and mildew growth, nail pops and sag (in the case of ceilings). Paper-to-core bond
failure and board sag are irreversible damages and the board should be replaced.
Mold can be cleaned using vinegar and water solution or alternates (use care when
using bleach or chlorine solutions). For nail pops, place a fastener an inch above
or below any popped-up nail.
Q:
Should gypsum board be installed vertically or horizontally?
A:
While gypsum boards are stronger in one direction, they may be installed either
vertically or horizontally on wood or steel studs. If the boards are to be used
in a fire rated assembly then use the board orientation that is stated in your specific
rated assembly.
Q:
How often is a control joint required?
A:
The requirement for ceilings and walls is the same. A control joint should be installed
every 30 feet when there is not perimeter relief. When there is perimeter relief,
control joints can be installed every 50 feet.
