Asphalt sealers contain materials that coat and protect a driveway. Different mixtures have different benefits, so a homeowner must choose a formula that protects well in his climate. Sealers must be applied when the air temperature is between 45 and 95 degrees Fahrenheit and three days of dry weather are expected.

Carefully trimming the grass edges and cleaning up gas and oil spills with soapy water and a stiff brush are the first steps in prepping a driveway for sealing. Sweeping up any debris, filling large cracks and pot holes with patching compound, and hosing the driveway off complete the process.
