Martco Limited Partnership, Alexandria, La., announces the availability of MoldShield™ Mold-Resistant Barrier System, an oriented strand board panel manufactured with a protective mold-resistant coating that is custom blended by Kop-Coat Inc. The panels are coated on all surfaces to effectively defend against mold growth through shipping, storage and construction. They inhibit mold growth before it starts, eliminating the need for costly on-site treatment or remediation. Because MoldShield is factory-applied, it is bonded to the OSB, and does not require repeat field treatments. The panels can be cut, drilled, sanded and disposed of in the same manner as uncoated panels.
