The original heavy-duty graphics art board, GatorFoam has a polystyrene foam center bonded between a wood-fiber laminate. It is rugged and durable, and resists dents and punctures. It works well for mounting photos or murals because of its flat surface and warp resistance. It can be directly printed or painted with no special preparation. The surface accepts both digital printing or screen-printing. It can be used for latex, oil-based or acrylic paints, and is suitable for both indoor and outdoor signage. Gatorfoam is 3/16" thick.
