Product Details
A MOLD-RESISTANT WALL BOARD IDEAL FOR HIGH-HUMIDITY INTERIOR RESIDENTIAL AND COMMERCIAL APPLICATIONS.
Manufactured to meet ASTM C1396 Section 7. ToughRock® Mold-Guard™ Gypsum Board is designed to provide extra resistance against mold and mildew compared to traditional paper-faced gypsum board products. When tested, as manufactured, per ASTM D3273 (“Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber”), ToughRock Mold-Guard Gypsum Board achieved a score of 10 – the best possible score for this test.1 It’s ideal for high humidity interior areas such as kitchens, bathrooms, basements and laundry rooms.
1The score of 10 in the ASTM D3273 test, indicates no mold growth in a 4-week controlled laboratory test. The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled, laboratory setting. No material can be considered mold proof. For additional information concerning mold resistance, see www.buildgp.com/safetyinfo. When properly used with good design, handling and construction practices, ToughRock® Mold-Guard™ Gypsum Board provides increased mold and moisture resistance compared to standard paper-faced wallboard products. However, the product is not intended for immersion in water or prolonged exposure to moisture. As with any building material, avoiding water exposure during handling, storage and installation, and after installation is complete, is the best way to avoid the formation of mold or mildew.

FAQs
While ToughRock® Mold-Guard™ has enhanced moisture and mold resistance compared to traditional paper-faced gypsum board, it is not recommended or warranted for exposure to the elements. We would recommend DensArmor Plus® Interior Panels for pre-rock conditions.
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.
