Asphalt Sealing is a heavy duty protective coating. Technically speaking, it is a high solids colloidal dispersion of selected coal tar pitch in water. Sealer can be applied without heating at temperatures above 50° F. Upon curing, the mixture forms a tough, charcoal black barrier of coal tar pitch heavily fortified with inert minerals which is highly resistant to the prevailing elements that damage asphalt pavements. Continuous laboratory control, as well as high volume production advantages, are your assurance of consistent quality. All of the sealer used for seal coating is federal spec. rubber fortified material with approximately 4-6lbs. sand per gallon.
