Form 26-1M Wall-Matte Chart

Form 26-1M is a white and gray wall-matte chart. The top and bottom sections are white and the middle section is gray.

These charts are coated with a flat finish similar in texture and "tooth" to a typical trade sales flat wall paint. Paints can be applied by brush or roller with assurance that there will be no surface "skid" during application. The surface is well sealed so that both water based and solvent based coatings can be applied with no penetration of vehicle into the substrate.
