Asphalt pavement fades in appearance over time due to exposure to the environment. Asphalt looks better when a new sealcoat has been applied, and it also performs better. More importantly, seal coating safeguards and up to 300% increases the lifespan of asphalt surface. Sealcoating works as a barrier to ward off gasoline, oil drippings, grease, and de-icing salts as well as acting as a protection against weathering effects and oxidation from harmful UV radiation.
