  1. Wash and degrease the driveway

    Wash the asphalt with a pressure washer, and inspect it for oil stains. Scrub the stains with a scrub brush and degreaser. Use the pressure washer to clear vegetation and dirt from cracks in the asphalt.

  2. Repair damaged areas

    Insert asphalt backing rods into the cracks, and cover the rods with asphalt filler putty. Smooth the surface and dry the putty according to the manufacturer's instructions. Use a pry bar to remove large damaged sections of asphalt, fill the holes with 1 inch of fresh asphalt and tamp it down. Continue adding and compacting 1-inch layers until the repaired area is level with the surrounding asphalt.

  3. Apply sealer

    Trim the edges of the driveway and cover adjacent hard surfaces with masking tape. Apply sealer to the driveway perimeter with an asphalt brush, and use a floor squeegee to coat the rest of the asphalt. Let the sealer dry according to the manufacturer's recommendations.
