Definition: A rigid sheet of foam core that has been coated with adhesive, such as sticky or heat-activated, and used for mounting posters.
Adhesive coated boards are a specialized type of foam board that come pre-applied with an adhesive layer, saving time and materials in the mounting process. They are available in both pressure-sensitive (sticky) and heat-activated varieties, each suited to different applications. These boards are popular in picture framing and display work because they streamline the process of attaching artwork, posters, and photographs to a rigid backing surface.
Framers often use adhesive coated boards when working with posters, inexpensive prints, or commercial displays where conservation-grade methods are not required. The adhesive backing ensures smooth, uniform contact with the artwork, reducing bubbling and warping that can occur with manual adhesive application. Heat-activated boards, in particular, provide strong long-term bonds when used with a heat press, making them a preferred choice for permanent mounting projects.
While adhesive coated boards are effective for general mounting purposes, they are not recommended for valuable or irreplaceable artwork. The adhesives used can degrade over time, leading to discoloration, brittleness, or difficulty removing the artwork without damage. For conservation framing, reversible mounting methods such as hinges or archival corners are preferred.
