In order for corrosion-resistant coatings to perform properly, they must first properly adhere to the substrate they are applied onto. The cross hatch adhesion test is a standardized test conducted to ensure that the paint coating applied on its substrate adheres properly. A cutting guide and blade or a special crosshatch cutter are used to cut the surface coating, and to ensure that the cuts are parallel to each other with the proper spacing. Afterwards, a piece of tape is applied over the cross-hatch markings, and then quickly peeled off to examine if the coating remains on the substrate.
