How to Seal a Driveway: DIY Guide for Asphalt & Concrete
Sealing your driveway every 3–5 years extends its life by 10–15 years and costs just $50–$200 in materials vs. $200–$500 to hire a pro. This is one of the best value-for-money DIY projects you can do.
Asphalt Driveway Sealing
Materials Needed
- Asphalt driveway sealer (1 bucket covers ~250 sq ft)
- Crack filler (for cracks over 1/8 inch)
- Long-handled squeegee or brush applicator
- Stiff broom for cleaning
- Garden blower or leaf blower
Steps for Asphalt Sealing
- Clean thoroughly – Sweep, blow out debris, remove oil stains with degreaser
- Fill cracks – Use rubberized crack filler for any cracks; let cure 24 hours
- Check weather – Apply only when temp is above 50°F and no rain expected for 24–48 hours
- Apply sealer – Pour a ribbon across the top of the driveway and spread with squeegee in long, even strokes
- Apply second coat – In the perpendicular direction after 4–8 hours
- Stay off driveway – 24 hours for foot traffic, 48–72 hours for cars
Concrete Driveway Sealing
Concrete sealers penetrate and protect against water, stains, and freeze-thaw damage. Use a penetrating silane-siloxane sealer for driveways — apply with a pump sprayer, let soak for 10 minutes, then spread evenly with a broom. Reapply every 3–5 years.
Pro Tips
- Don\’t seal a new asphalt driveway for at least 12 months
- Over-sealing causes premature peeling — stick to every 3 years
- Morning is the best time to apply — cooler temps allow better penetration
