Asphalt sealing is a protective coat that is applied to driveways and parking lots. New asphalt should not have a seal coating for a least 1 year from installation as new asphalt needs time to set and cure. New seal coating can preserve the resilience of asphalt surfaces and help hide and seal small cracks, patches and rough spots, as well as making traffic lines on parking lot lines more visible. Another benefit of seal coating is that it helps protect the asphalt from the sun as well as the harmful effects of chemical spills; such as oil and gasoline both which are all too common on a driveway and parking lot.
Asphalt seal coating fills surface voids which reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the asphalt.
The price of asphalt will always be affected by crude oil prices which fluctuate when supplies vary. Seal coating preserves asphalt for pennies per square foot, verses costly asphalt repairs.
