If everyday wear and tear has left your driveway looking less than its best, take a couple afternoons and reseal it. First you'll need to clean the driveway and let it dry out overnight. Then, repair any cracks with a crack filler designed for asphalt. After that, apply asphalt sealer according to the manufacturer's instructions and work it over the entire driveway in an even layer. Once the driveway fully dries, it is sure to look as good as new.
