Resin impregnated, chemically purified wood pulp boards are bonded to both sides of a high density, smooth-cutting polystyrene core. The smooth finish board accepts screen printing, acrylic and oil paint, and is sufficiently water resistant to withstand exterior use. Uniform density allows cutting by hand and power tools, use of screw or wire fixings, and a variety of adhesives and laminating fabrics. When mounting acid-intolerant material for prolonged display it is advisable to laminate the mounting surface of Gatorfoam with an alkaline paper or board. Microchamber paper and paints could also be used for this purpose.
