SEALCOATING PROTECTS FROM OXIDATION
Oxygen reacts with the tar in asphalt to make it hard and brittle, even¬tually leading to cracks in the pavement. As air and rain¬water fill the cracks, the surface continues to dete¬ri¬orate. Seal¬coating seals off the asphalt from the air, protecting it from the harmful effects of oxygen and water.
SEALCOATING PROTECTS FROM ULTRAVIOLET RAYS
The same rays that cause sunburn also damage pavement by destroying carbon bonds in the asphalt, resulting in crum¬bling. Seal¬coating can be thought of as putting two years’ worth of sunscreen on your driveway.
SEALCOATING PROTECTS FROM GASOLINE AND OIL
Gasoline and oil eat away at pavement, slowly soft¬ening it and causing it to dete¬ri¬orate. Seal¬coating resists gas and oil, thus preserving the life of the asphalt underneath.
SEALCOATING MAKES YOUR DRIVEWAY BETTER LOOKING AND EASIER TO MAINTAIN
Seal¬coating restores the deep black color of new pavement. It also results in a smoother surface which looks good and is easier to clean or shovel.
WHEN SHOULD YOU SEALCOAT?
A new asphalt driveway should be sealed between ninety days and a year after its completion. After that, a driveway should be seal coated every two or three years in order to maintain a good level of protection. Seal¬coating wears away over time, and once it is gone there is nothing standing between your paved surface and the elements.
