Paints are generally applied to aluminum at a thickness of between 20 and 25 µm, primers and reverse coatings at between 3 and 5 µm. These coatings can have a more or less glossy or matte appearance, depending on their use: for example, bodywork is in the high-gloss range, construction in the semi-gloss and satin range, and ceilings in the matte range.
