Fading-Poor Color Retention:
Premature and/or
excessive lightening of the paint color, which often
occurs on surfaces with sunny southern exposure.
Fading/poor color retention can also be a result of
chalking of the coating.
Possible Causes:
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.
Solution:
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 colors recommended for exterior
use. |
