Why do paint colours fade?
When paints are tinted, colorants are added to them, in a sufficient quantity to shade the base paint to match a particular colour. These colorants are made from either inorganic or organic ground pigments held in a dispersion liquid, and are mixed into the paint.
When exposed to UV light, such as from the sun, the resin of the paint, which holds in the pigments and protects them, begins to break down, eventually causing the pigments to become unbound and exposed to UV rays themselves. Over time, this process, which is called photodegradation, causes a bleaching effect.
What can be done to slow down the impact of photodegradation and make colours last longer?
