Step-by-Step Guide to Sealing a Driveway
Preparing the Driveway Surface
Before sealing, the driveway surface must be thoroughly cleaned. Any dirt, debris, or loose materials will prevent the sealer from bonding to the surface.
Start by removing loose debris using a leaf blower or stiff bristle push broom. A pressure washer or power washer should then be used to clean the entire surface, paying close attention to edges and low spots where dirt builds up.
If oil stains are present, they must be treated to remove oil fully. A dedicated driveway cleaner, combined with a wire brush, helps break down residues that would otherwise interfere with proper sealing.
Rinse thoroughly using a garden hose or pressure washer and allow the driveway dry completely before moving on.
Filling Cracks and Repairs
Sealing does not repair damage. All cracks, including hairline cracks and small cracks, must be addressed first.
Use a quality asphalt crack filler to fill cracks and prevent water penetration beneath the asphalt.
If the driveway shows new cracks or signs of extensive damage, sealing alone may not be appropriate.
Allow all repairs to dry completely and become fully dry before continuing.
Skipping this step shortens the life of your driveway and leads to premature failure of the seal coat.
Applying the Seal Coat
Once preparation is complete, it’s time for applying sealant. Use asphalt based sealers or approved coal tar sealers, mixed thoroughly with a mixing paddle to ensure consistency.
Apply the first coat using a squeegee or brush, working evenly across the driveway surface. A spray system may be used for larger areas, but manual control is often better near edges, garage door thresholds, and adjacent surfaces such as concrete.
Avoid using a thick coat. Instead, apply thin coats to achieve better adhesion and a stronger protective layer. Allow the first coat to set for several few hours, depending on weather conditions.
Once the surface is no longer tacky, apply the second coat in the opposite direction for a more uniform appearance. In some cases, two coats are sufficient; applying one thick coat often leads to uneven curing and poor durability.
Why Proper Sealing Matters
Consistent sealing protects asphalt from uv rays, rain, and freeze thaw cycles.
Without a sealed driveway, moisture seeps into cracks, weakens the base, and shortens the life of your driveway.
However, it’s important to avoid sealing too frequently. Avoid sealing a driveway annually, as excessive buildup can cause peeling and surface failure.
Always check the weather forecast and choose dry weather with stable weather conditions to ensure proper curing and optimal drying time.

FAQs
How long should a driveway stay off-limits after sealing?
Most sealer products require sufficient drying time before traffic. Light foot traffic is often allowed after several few hours, but vehicles should wait longer until the surface is fully dry.
Can sealing fix structural cracks?
No. Sealing protects the surface, but deeper cracks and base issues must be repaired before sealing begins.
What happens if it rains after sealing?
Rain during curing can damage the seal coat. Always check the weather forecast and plan around stable weather conditions.
What happens if it rains after sealing?
Yes. Plastic sheeting helps protect adjacent surfaces, landscaping, and concrete from accidental sealer contact.
What happens if it rains after sealing?
Some environmental concerns exist around certain materials. Professional contractors select products that balance performance and environmental responsibility.
