Poor Gloss Retention

Causes

• Use of an interior paint for an exterior application
• Use of an oil-based paint in areas exposed to ultraviolet light, especially on a southern exposure

Solutions

• Surface preparation for a paint showing poor gloss retention should be similar to that for chalking. See Chalking for more information.
• Use a high-quality, exterior, water-based latex paint, formulated to resist ultraviolet deterioration.
