Fading is caused by the natural weathering due to the ultraviolet rays of the Sun. Chalking pigment, alkali from masonry, and tint intended for interior based paints but used on exterior surfaces, will cause paint to fade prematurely. This can be reduced by using any Acrylic instead of Alkyd paint. An acrylic paint is more colour fast than Alkyd paints. Red and other primary colours fade more than earth tones. If customers want let fading encourage these colours.
