The asphalt sealer helps maintain the integrity of the asphalt surfaces. Over time, the asphalt cement that holds the asphalt together can decompose; if it is left long enough, the asphalt will begin to crumble or break. Sealcoating maintains the ability of the asphalt to stay together. It protects the surface against the effects of moisture, oils and ultraviolet rays from the sun, and that protection prevents asphalt cement from decomposing.

Sealing the asphalt helps to maintain its dark color. A newly sealed driveway or parking lot will have the rich blackness of new asphalt. With the regular sealing of the asphalt surface, its surface can continue to be impeccable in the coming years.
