<p>The invention relates to a method for the surface treatment of a metallic material, the coating being designed for creating an artificial patina in a copper-bearing material after the material is installed in its final location of use. According to the invention, in connection with the filtering and washing stage, including at least one step, of the precipitate formed of the ingredient components of the coating material, the solids content of the precipitate is adjusted within the range of 15 - 50 % by weight, as calculated from the weight of the coating material after the filtering stage, and the coating material with an adjusted solids content is stored at a temperature lower than 5 DEG C prior to applying said coating material onto the target surface.</p> |
