White surfaces for clean display work, gray tones for photography and color-critical mounting, and economical chipboard for everyday backing applications.

The 3X White Mounting Board features buffered, acid-free surface papers on both sides, essential when you're unsure which face will be visible or when both sides need presentation quality. Heavy-weight No. 91 Presentation Board delivers double-sided mounting capability with substantial rigidity for framed work. The 50% Gray and 80% Gray variants build high-quality surface papers over black solid cores, providing neutral backgrounds that won't distort color perception when mounting photography or color studies.

Medium-weight chipboard (.052 thickness) handles routine backing and mounting tasks where conservation properties aren't required, offering an economical alternative for studies, temporary displays, or work-in-progress mounting. When you need specific thicknesses, No. 80C provides heavy-weight .080 construction (3/32 inch), while No. 40C offers medium .040 weight in two size options. No. 15C delivers extra-heavy construction for maximum rigidity. Match the board weight to your application: lighter weights for flexible mounting, heavier constructions for unsupported display or larger works requiring structural integrity.
