How to Prepare Your Driveway for Sealing

Prepping the Surface

Before you begin sealing your driveway, it’s crucial to prepare the surface properly. Start by removing any debris, such as leaves, branches, and dirt, using a broom or leaf blower.

Next, use a pressure washer to clean the entire driveway thoroughly. This step is essential to remove any stubborn stains, grime, or oil spots that could prevent the sealer from adhering properly. If you don’t have a pressure washer, you can rent one from a local hardware store or hire a professional driveway sealing ottawa┬ácompany to do the job for you.

Repairing Cracks and Holes

Once your driveway is clean and dry, it’s time to address any cracks or holes. Small cracks can be filled with a crack filler, which can be found at most hardware stores. For larger cracks or holes, you may need to use a patching compound.

Be sure to follow the manufacturer’s instructions carefully when applying the filler or patching compound. Allow ample time for the repairs to dry completely before moving on to the next step.

Choosing the Right Sealer

There are two main types of driveway sealers: coal tar and asphalt. Coal tar sealers are more durable and resistant to oil and gas spills, but they have a strong odor and can be harmful to the environment. Asphalt sealers, on the other hand, are more environmentally friendly and have a milder odor, but they may not last as long.

Consider your budget, environmental concerns, and the condition of your driveway when selecting a sealer. If you’re unsure which type to choose, consult with a professional or visit your local hardware store for guidance.

Applying the Sealer

Once you’ve chosen your sealer, it’s time to apply it to your driveway. Begin by pouring a small amount of the sealer onto the driveway and spreading it evenly using a squeegee or brush. Work in small sections, overlapping each pass slightly to ensure even coverage.

Be sure to follow the manufacturer’s instructions regarding the number of coats needed and the drying time between coats. Typically, two thin coats are better than one thick coat, as this allows the sealer to penetrate the surface more effectively.

Allowing Adequate Drying Time

After applying the sealer, it’s crucial to allow sufficient time for it to dry completely before using your driveway. The drying time will depend on the type of sealer you used, as well as the temperature and humidity levels.

As a general rule, allow at least 24 hours for the sealer to dry before walking on it, and wait 48-72 hours before parking vehicles on the surface. If possible, plan your sealing project during a stretch of dry, sunny weather to ensure optimal drying conditions.

Maintaining Your Sealed Driveway

To maximize the lifespan of your newly sealed driveway, it’s important to maintain it properly. Avoid parking heavy vehicles or equipment on the surface, as this can cause the sealer to crack or peel prematurely.

Clean your driveway regularly to prevent the buildup of dirt, grime, and oil stains. If you notice any cracks or damage, address them promptly to prevent further deterioration.


Sealing your driveway is an excellent way to protect it from the elements and extend its lifespan. By following these simple steps and maintaining your sealed surface properly, you can enjoy a beautiful, durable driveway for years to come.
