Sealing blacktop driveways is an easy job—if it’s done right. The project requires the right preparation before sealing, proper tools, supplies and an asphalt sealant you trust to get the job done. High-quality asphalt sealers, like INTEGRA-SEAL, reduce heat and UV damage and prevent water from penetrating pores and cracks during freeze and thaw cycles.
If you want your pavement to last for years, follow these steps to learn how to seal your asphalt driveway.
Preparation Before Sealing Blacktop Driveways
It can take a whole day to clean and prepare your asphalt driveway for sealing. Plus, you’ll want to budget time to apply two coats of product and allow the driveway surface to dry for at least eight hours between coats. As you plan when to start your sealing project, it’s a good idea to monitor the weather and choose two days where temperatures are expected to be above 45° F.
To get started, follow these steps:
- Clean and prime your driveway.
Use a leaf blower or broom to clear away dirt and debris. Pick weeds and remove moss. Use a degreaser or primer to remove oil and gasoline spots.
- Rinse with a power washer or garden hose.
Wash the driveway surface using a power washer or garden hose with a spray nozzle. Let the driveway dry completely before repairing cracks in the pavement.
- Fill asphalt cracks.
Asphalt cracks allow water and chemicals to permeate deep into the pavement. To prevent water damage, fill cracks with a trustworthy crack filler, such as KOLD-FLO® pourable crack filler.

- Protect and mask off driveway edges.
Asphalt sealer is messy. It splashes on clothing, garage doors and sidewalks. Before applying sealer, protect nearby doors and surfaces with drop cloths. Mask off driveway edges and use a small brush to ensure clean lines when you apply your sealer.
- Pour the sealer onto the driveway and spread carefully.
Beginning in the top corner of the driveway, pour the sealer on the driveway. Use a long-handled squeegee to spread a thin layer over the asphalt. Repeat this step until you reach the end of the driveway.
- Allow the sealer to dry and apply a second coat.
Let the first coat of asphalt driveway sealer dry for eight hours. Then, apply a second coat and wait 24–48 hours before opening the driveway to vehicle traffic.
