Gator Board

Much stronger than foamcore, but about the same weight.

Gator board has a very rigid coating which is resistant to moisture,unlike foamcore board which is foam covered with light wieght paper

Gator board is an extruded polystyrene foam mounting board encased between layers of a melamine and wood fiber veneer. Gatorfoam / Gatorboard has a much harder outer surface than other foam core boards and resists warping.

Gator board is not an acid free material, so you should check before using it for items which will be displayed in museums or other permanent archives.


For miniature builders, Gator board is often used as a backing for wet materials like paper-clay or stucco finishes which require a water resistant backing while the coating dries.


Gator board is available in a white, black or natural (kraft) finish.

For special applications (mounting photos and posters) it is available with an adhesive coating already applied. See: SELF ADHESIVE GATOR BOARD

Black Gatorboard is not recommended for outdoor use as the color accelerates UV breakdown.

Working With Gatorboard

The outer surface of Gatorboard is strong and chips unless cut by fine sharp blades. Hand cutting of Gatorboard is not recommended although it can be hand cut after scoring it with a very sharp, short craft blade. (Something similar to the knives used to cut melamine counter-top material.) Hand jig saws or coping saws are preferable for hand cutting simple shapes, more elaborate cuts should be done with power tools.

Gator board is easily cut with a power saw or router using sharp, fine tooth blades. It can be glued to the face of a structural framework, or held together with wooden dowels or biscuits to build without a frame.

Before gluing or painting make sure the surface is clean and dry. If necessary, scuff the top surface using 180 or finer grit sandpaper to create a better surface for bonding (when using glues other than contact cement).
