Give us a call for a Free Estimate! In some cases, if there are cracks in the pavement, we will have to repair them before we can apply a sealcoat. We will then apply a liquid tar emulsion over the surface of the asphalt. The procedure of applying the sealcoat and allowing it to dry and cure is usually done within a few hours. Not only will you dramatically extend the life of the asphalt, but you will greatly reduce the amount of money you would otherwise have to put toward future maintenance costs.
