How Do You Seal a Blacktop Driveway?

After preparing the surface of the driveway by removing any debris and fixing any cracks or holes, pour your choice of sealer onto the asphalt and use a long-handled squeegee or thick-nap roller to fully spread it across the surface of the driveway. Depending on the type of sealer used, the driveway dries completely within four to 24 hours. The length of a particular sealant's drying time is often specified in the product's instructions.
