Ability of any pigmented organic coating to hide or obscure the surface of the substrate. Hiding power is assessed by applying successively increased thickness of paint over a black/white contrast strips or checkerboard squares until the color difference in the background contrast could be no longer noted. The dry film thickness at this point refers to hiding power and it is defined in micrometers. Hiding power directly changes with the opacity of the applied coating film. See Also Opacity
