Seal an Asphalt Driveway

You'll get a big bang for your buck by topcoating an asphalt driveway with sealer because it's a low investment in time and money that produces a dramatic change for the better. For a typical 500-square-foot driveway, the material costs $20 compared with $60, which is what a contractor will charge to do the job. That's a savings of 65 percent.

It's an easy two-hour project, but preparing the surface and the soil around the driveway may require more time depending on their condition. Remove grease or oil spots on the surface with an asphalt cleaner and use an asphalt patching compound if there are deep cracks or pot holes. Small cracks can be filled with sand mixed with sealer.

Pull any weeds growing alongside the driveway and rake the area so it is neatly edged.

Thoroughly sweep the surface and then apply the sealer with an old push broom or applicator. Spread the sealer beginning at the garage door and work your way out toward the street. Pro vs DIY Cost and TimeBarricade the wet surface with empty sealer cans and park your car elsewhere while the coating dries.

Dress down for the job by wearing old clothes and shoes. Check the soles of your shoes before going inside so you don't track in wet sealer.
