3-Part Guide Specs




Extra protection against mold and mildew

Fights the effects of moisture before damage can occur

  • For use in all rooms.

XP® Gypsum Board was designed to provide extra protection against mold and mildew compared to standard gypsum board products. The face paper is folded around the long edges to reinforce and protect the core, and the ends are square-cut and finished smooth. Long edges of the panels are tapered.

With PURPLE paper on the face side and heavy, mold/mildew/moisture, 100% recycled gray paper on the back side, you can count on XP Gypsum Board to help protect your projects from mold.
