| Fading / Poor Color Retention |
 | | | | DEFINITION
Premature and/or excessive lightening of the paint color that typically occurs on surfaces with southern exposure. Fading/poor color retention can also be a result of chalking of the paint film.
PROGRESSION
Newly painted surface loses its fresh appearance over time. Once vibrant colors seem to become dull; dark colors seem to lighten in appearance.
CAUSES
- Use of a low quality paint, or interior grade of paint for an exterior application.
- Use of a paint color that is prone to ultraviolet deterioration (e.g., certain bright reds, blues, and yellows).
- Painting masonry surfaces, such as stucco and concrete, that are not cured properly, resulting in alkali “burn” (see Poor Alkali Resistance).
- Tinting a white paint that has not been designed to be tinted, or adding too much colorant to a light or medium paint base.

| FIXING PROBLEM | | DUNN-EDWARDS SOLUTIONS | | | | | When fading/poor color retention is a result of chalking, it is necessary to remove as much of the chalk as possible (see Chalking). | | | | | | | When fading/poor color retention is a result of alkali “burn”, the surface should first be primed with an alkali-resistant primer before applying the finish coat. | |
Dunn-Edwards' "Eff-Stop, W 709" acrylic masonry primer provides very good alkali resistance.
| | | | | When repainting, be sure to use a high quality exterior paint and colors that are recommended for exterior use. | |
