You'll turn heads in the neighborhood when you seal a driveway, as even the most handsome house looks shabby when surrounded by a driveway pockmarked with cracks and crevices. But sealcoating is more than a cosmetic change: It prevents damage from the sun and moisture, both conditions that creates cracks and crumbling in the driveway surface.
A sealing company will charge $341 to seal a typical 20-by-50-foot driveway in good condition, which includes the labor and material; but you can do it yourself for $200 and save 42 percent. You'll get the best results sealcoating if you spend time preparing the surface and the lawn along its edges. Pull weeds, rake and edge so the soil is neatly trimmed back from the driveway surface. Fill any cracks and potholes with an asphalt patching material and use an asphalt primer or cleaner to remove any grease spots. Sweep the driveway, and then scrub it with soapy water before applying sealer. The actual application of the blacktop sealer is the finale and takes much less time than the prep work.
Use a push broom or applicator to spread the blacktop sealer working your way from the garage out to the street. To give the seal coating time to bond to the surface and dry quickly, apply two thin coats instead of a heavy one. Asphalt is messy stuff, so be careful where you step. Before walking inside the house, check the soles of your shoes for sealer.
If you’re sealcoating in the summer and the temperature of the pavement is above 85 degrees, give it a light mist with the garden hose to cool the surface which makes the blacktop sealer easier to apply and spread.
