Side length: 40mm. Method of use: All types of coating after construction immediately position the wet film thickness indicator upright on the surface smooth of the coating, measure the thickness of the wet film thickness of the wet film and measure the thickness of the wet film. The thickness of the wet film should be between the shortest tooth and the adjacent tooth that is not immersed in the wet film. The same method is used to measure twice in different positions to obtain a certain range of representative results. After use, the wet film thickness gauge is cleaned and dried.
