Seal coat brings back the dark black color of the original pavement.
Asphalt pavement begins to deteriorate almost as soon as it is installed. As the pavement is exposed to oxygen, the asphalt oxidizes. This oxidization results in a brittle surface that eventually cracks. Seal coat protects the surface and fills surface voids, reducing pavement’s exposure to oxygen and water and extending pavement life.
By breaking down the links between the carbon bonds in the asphalt, ultraviolet rays cause pavement to deteriorate and crumble. Regularly applied sealcoat helps to prevent ultraviolet rays from penetrating the pavement.
This is especially important on driveways where cars are parked or worked on. Oil and gasoline soften asphalt. By filling surface voids, sealcoat also reduces the depth to which oil or gas can penetrate the pavement.
Seal coated pavement is also easier to clean and maintain. Because sealcoat fills surface voids, a sealcoated surface is much smoother. And a smoother surface is easier to sweep, shovel, and wash.
