Gatorfoam Solutions Near Baltimore, Gatorfoam is a lightweight, rigid display board with a polystyrene core and white surface. The core is very dense and firm and the surface is a wood fiber veneer laminate impregnated with resin for water resistance. Gatorfoam cuts cleanly with a knife, saw, or router.
Foamcore, foam board, or paper-faced foam board is a lightweight and easily cut material used for mounting of photographic prints, as backing for picture framing, for making scale models, and in painting. It consists of a board of polystyrene foam clad with an outer facing of paper on either side, typically white clay-coated paper or brown kraft paper.
The surface of the regular board, like many other types of paper, is slightly acidic. However, for modern archival picture framing and art mounting purposes, it can be produced in a neutral, acid-free version with a buffered surface paper, in a wide range of sizes and thicknesses.
Foam-cored materials are also now available with a cladding of solid (non-foamed) polystyrene and other rigid plastic sheeting, some with a textured finish.
Foamcore does not adhere well to some glues, such as superglue, and certain types of paint. The foam tends to melt away and dissolve. Some glue works well in casual settings, however, the water in the glue can warp the fibers in the outer layers. Best results are typically obtained from higher-end spray adhesives. A hot glue gun can be used as a substitute, although the high viscosity of hot glues can affect finished projects in the form of board warping, bubbles, or other unsightly blemishes.
Self-adhesive foam boards, intended for art and document mounting are also available, though these can be very tricky to use properly; this is because the glue sets very fast. It is considered cheaper to buy plain foam boards and use repositionable spray mount adhesive.
