Sealer should be applied only in hot, summer months and when rain is not expected for at least 36 hours. Do not apply the sealer unless the temperature will be above 60 degrees for the next 24 hours.
Start by barricading the driveway against traffic and power-washing the surface. Before applying sealer, put on old clothes and tie up your feet with plastic bags to protect your shoes.
Pour about two gallons of sealer on to the driveway. Work in small areas so it won’t dry out before you get it spread. Coverage should be as thin as possible. A squeegee will help pull the sealer to the edges. Don’t walk on your new surface for several hours and let it dry overnight before driving on it. The next day, your asphalt driveway will look brand new.
