Premature and/or excessive lightening of a paint colour, which often occurs on surfaces with high levels of sun exposure. What happens to be a fading/poor colour retention issue can also be a result of chalking (see Chalking).
Use of an interior grade of paint for an outdoor application
Use of a lower quality paint, leading to rapid degradation (chalking) of the paint film
Use of a paint color that is particularly vulnerable to UV radiation (most notably, certain bright reds, blues and yellows)
Tinting a white paint not intended for tinting, or over tinting a light or medium paint base
When fading/poor color retention is a result of chalking, it is necessary to remove as much of the chalk as possible (see Chalking). In repainting, be sure to use a quality exterior house paint in colours recommended for exterior use.
