• Manifestations
  1. This is when the paint color lightens excessively and/or prematurely.
  2. It most frequently happens on surfaces that have sunny southern exposure.
  3. It can also result from chalking of the painted surface.
• Causes
  1. Using a grade of paint intended for the interior on an exterior surface.
  2. Using a low-quality paint that will result in rapid degradation (chalking) of the painted surface.
  3. Painting with a color particularly susceptible to damage from UV radiation.
  4. This includes bright shades of yellow, blue and red.
  5. Tinting white paint that is not manufactured to be amenable to tinting.
  6. Adding an excessive amount of tinting to paint that has a light or medium base.
• Solutions
  1. Removal of the chalk to the greatest extent possible.
  2. Then repaint the surface with a high-quality house paint manufactured for exterior use. Select a color that is appropriate for outdoor use.
