Large area, matte finish test surfaces for practical laboratory testing of wall paints by roller or brush application.
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 solvent borne coatings can be applied with no penetration of vehicle into the substrate. The gray stripe provides less contrast than black and white opacity charts, consistent with the practical nature off large area roller and brush application testing.
