The most common type of driveway sealant is blackjack. This sealant is a two-part system that is applied to the driveway with a sprayer. The first part is a liquid that is applied to the surface of the driveway.
The second part is a foam that is applied to the liquid and set with a roller. After the foam has set, the sealant is sanded down to the desired level. .
The blackjack sealant can be used on both concrete and asphalt driveways. It can be used in cold or hot weather, and will last for up to two years.
The blackjack sealant can be painted over if desired, but should not be sanded down again.
