Component Life Expectancy
Paints and Sealant
Surface preparation and paint quality are the most important determinants of a paint’s life expectancy. Ultraviolet (UV) rays via sunshine can shorten life expectancy. Additionally, conditions of high humidity indoors or outdoors can affect the lifespan of these components. Paints and sealants should be inspected and maintained seasonally.
