Does Ultraviolet from the sun affect Precision Board Plus?
Yes. Left in the sun unpainted, Precision Board Plus will start to discolor and turn brown in about 48 hours. Left totally unprotected Precision Board Plus will continue to turn brown and breakdown from UV at about 1/32″ per year. This means about 1″ of deterioration every 32 years. Obviously deterioration is not a problem but the brown color is not pleasing. However, just under the brown surface the cell structure is unaffected. When this surface is removed it is ready for primer and paint. Keeping the painted surface looking good will assure a very long service life.
