Fading/Poor Colour 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 the result of chalking of the coating.

Possible Cause:

• Use of an interior grade paint for an outdoor application.

• Use of a lower quality paint, leading to rapid degradation (chalking) of the paint film.

• Use of 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 overtinting a light or medium paint base.

Solution:

When fading/poor color retention is the result of chalking, it is necessary to remove as much of the chalk as possible (see chalking). If repainting, be sure to choose a quality exterior latex house paint in colours recommended for exterior use.
