Wall-Matte Charts

Large-area matte finish test surfaces for practical laboratory application testing of wall paints.

Request Info

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 waterborne and solventborne coatings can be applied with no penetration of vehicle into the substrate.

Wall-Matte Charts are an effective replacement for previously available Kem-Glo Test Paper and superior to that product in imperviousness and paper rigidity.
