Asphalt is a popular road and driveway surfacing material because of its ease of installation and long lifespan. Asphalt is made of aggregates held together by bitumen, usually produced during the oil refining process. Asphalt is strong and waterproof, and it absorbs heat and light. Traction on asphalt surfaces can be affected by moisture, freezing conditions, and oil or gasoline spills.
Apply a sand seal to your asphalt driveway to increase the overall grip of the surface and improve traction. Sand seals consist of liquid asphalt blended with fine sand. The treatment seals any existing holes or flaws and adds a layer of grit. Use a broom to sweep away any debris from the driveway surface in preparation for application.
Use asphalt cleaner to remove any spill residue or stains from the surface of the driveway. Use the cleaner according to the manufacturer's instructions, then allow the driveway to dry completely.
Use asphalt crack filler to close up any large cracks in the surface of the driveway. Apply the filler according to the manufacturer's instructions. Allow the crack filler to dry completely before you move ahead with the process.
Apply the asphalt sand sealer to the driveway surface in the morning hours. The driveway should have as much exposure to sun as possible to aid in the drying process. Mix the sealer thoroughly before application, then apply it to the surface with a squeegee. The padded side of the squeegee should be dipped into the sealer solution then used to spread the sealer across a 4-foot square patch of driveway.
Work the sealer into the surface in one direction, then turn 90 degrees, and repeat the process. Continue brushing until there is a smooth and uniform coat over the entire driveway. Allow the sealer to dry according to the manufacturer's instructions. Remove any lines or lumps from the sealer with the back side of the squeegee before it dries.
