How to Seal Your Driveway Like a Pro

Seal your driveway by cleaning thoroughly, filling cracks, applying primer if needed, then spreading sealant evenly with a squeegee or brush in thin, overlapping coats.

1. Start with a spotless surface. Remove all dirt, oil stains, weeds, and debris from the surface. Use a pressure washer or garden hose with scrub brush for stubborn spots. Let the driveway dry completely for at least 24 hours before proceeding. Any moisture trapped under the sealant will cause it to fail prematurely.
2. Seal every imperfection first. Use crack filler or patching compound to fill any cracks wider than a quarter inch and holes deeper than half an inch. Smooth the filler level with the surrounding surface using a putty knife. Allow repairs to cure according to manufacturer instructions, typically 24-48 hours.
3. Block stains before coating. If your driveway has old oil stains, apply an oil-blocking primer to these areas first. This prevents the oil from bleeding through and compromising the sealant. Use a brush to work the primer into the stained area and let it dry completely.
4. Mix for consistency and color. Stir the sealant for at least five minutes with a mixing paddle or stick. Most sealants separate during storage, so proper mixing ensures even color and protection. If using multiple buckets, mix them together to avoid color variations across your driveway.
5. Spread thin and even coats. Start at the far end of the driveway and work toward your exit. Pour a ribbon of sealant across the width of the driveway, then spread it evenly using a squeegee or application brush. Work in 4-foot sections, maintaining a wet edge to avoid lap marks. Apply thin, even coats rather than one thick application.
6. Give it time to set. Allow the first coat to dry completely, typically 4-8 hours depending on temperature and humidity. The surface should feel dry to the touch and not tacky. Avoid walking on it during this time and keep pets and vehicles off the surface.
7. Cross-apply for maximum protection. Apply the second coat perpendicular to the first coat direction for maximum coverage and durability. Use the same technique as the first coat, working in manageable sections. Two thin coats provide better protection and appearance than one thick coat.
8. Stay off until fully cured. Keep the driveway clear of traffic for 24-48 hours after the final coat. Full cure time depends on weather conditions, but the sealant should be completely hard before normal use. Mark the area with cones or tape to prevent accidental traffic during curing.
