ProRoc® 1/2" (12.7mm) Sheathing Treated Core SE

CertainTeed ProRoc® Regular Gypsum Board accepts most types of paints, texture and wall covering materials. The surface shall be primed and sealed with a full-bodied latex primer before applying a final decorative material. This will equalize the suction between the joint compounds and the paper surface. For best painting results, all surfaces, including joint compound, should be clean, dust-free and not glossy. If glossy paints are used, a thin skim coat of compound over the entire surface, Level 5 finish, is recommended to reduce highlighting or joint photographing. This method is also recommended for areas of critical side lighting of natural or artificial light sources. A sealer application under wallpaper or other wall covering is also recommended so the board surface will not be damaged if the covering is subsequently removed during redecorating. Joint treatment must be thoroughly dry before proceeding with primer-sealer application and final decoration.

• The face and back paper used for our gypsum board consists of 100% recycled paper.
• Synthetic or “by-product” gypsum from the desulphurization of flue gases at coal-fired power plants is used where sources are available. Currently three manufacturing plants—Carrollton, Kentucky, Moundsville, West Virginia and Toronto, Ontario—use 100% synthetic gypsum. The total recycled content for these synthetic gypsum plants is 96%.
• In-plant scrap is recycled back into the process. Our 14 gypsum board manufacturing locations provide regional material coverage throughout North America.
• Although LEED rating systems do not currently address emissions for all building materials and their effects on indoor air quality, finished CertainTeed gypsum board products have no reportable VOCs and will not affect indoor air quality.
