Gold Bond® BRAND High Flex® Gypsum Board panels consist of a fire-resistive gypsum core encased in heavy natural-finish paper on the face side and strong liner paper on the back side. The face paper is folded around the long edges to reinforce and protect the core, and the ends are square-cut and finished smooth. Tapered edges allow joints to be reinforced with Proform® BRAND Joint Tape and concealed with Proform® BRAND Ready Mix or Quick Set Setting Compounds. For optimum mold performance, ProForm® BRAND XP® Ready Mix is recommended for use.
