A new gypsum board product has guide marks to identify the location of studs, joists, rafters, or trusses, and is intended to simplify the process of cutting and installing gypsum board. It helps installers find framing members and make accurate cuts without having to draw as many lines as conventional gypsum board installation requires. Marks are printed on the paper covering at distances commonly used for spacing framing members.
Gold Bond brand GridMarX® is National Gypsum Company's guide-marked gypsum board product. Grid marks consist of an "X" printed on the paper surface in rows parallel to the long dimension of the board. The rows run along each tapered edge and in parallel rows spaced 16, 24, and 32 inches from edges to help installers find fastening points for walls framed at 16- or 24-inches on center. The marks are spaced at 4-inch intervals along each row to facilitate fastening along studs. According to the manufacturer, marks are easily covered with standard paint.

Guide marked gypsum board is installed on walls and ceilings in the same way as conventional gypsum board. For horizontal installation (framing members perpendicular to long dimension of the board), the marks serve to help identify framing members. The installer will be able to move off the mark a certain distance to locate a framing member. In a vertical installation, guide marks can denote the exact location of framing members, since marks are located at common framing dimensions of 16, 24, and 32 inches. Installers can also use guide marks to space fasteners.
Not Applicable
Guide marked gypsum board can save time and labor costs, because installers can find framing members quickly, can easily locate cut-outs for utilities, and do not need to draw as many lines as they do without the guide marks. The product may also reduce the learning curve for new installers and expedite the code inspection process. Grid-marked gypsum board may improve installation quality due to the ease with which fasteners are accurately installed.
