Fading or chalking is another very common problem in Northern Virginia. Sunny days blast your home  with UV rays breaking down the resin in the paint. Resin is the primary component in paint that protects the  home. Pigment gives it the color. When the house starts to fade, this is an indication that the resin has broken  down in the paint and there is minimal protection on your home. Without protection on the house, moisture  will get into those boards (usually siding boards) and lead to warped siding boards which can be very expensive  to replace. We recommend a power wash to wash off any dust and residue from the chalking. For sides that  experience the most sunlight, we also recommend a second coat or a coat of primer for extra protection. This  will provide a higher level of resin and protection for that side of the home, ensuring that it will not fade as  quickly so you can avoid costly replacement costs in the future and a longer lasting paint job.
