Tools and Supplies

There are a few tools and supplies you’ll need to accomplish sealing your driveway. 


  • Squeegee
  • Paintbrush
  • Broom


  • Weedkiller
  • Crack filler
  • Driveway sealant 

You can purchase most of these materials at your local home improvement store. There isn’t much difference between Home Depot’s driveway sealer and Lowes’s driveway sealer, so you should have plenty of options wherever you decide to go. 

There is a variety of weed killers as well. Make sure you give the weeds enough time to die so they can be pulled up and scraped off the cracks. The area must be completely dry before you begin the sealing process.

Before You Seal

Make sure you have at least three days of sunny skies forecasted before beginning. The concrete driveway sealer needs time to dry and set. More details about how long you need to wait for the driveway sealer given below. 

After the sealing is finished, keep in mind you will need to wait 24 hours before walking on it and 72 hours before driving on it. Make sure you have an alternate parking spot for your car during that time.

If you have large holes in your driveway, you may need to use a driveway patch to fill those in. If so, those need 4 – 6 weeks to cure and would need to be done prior to the filling of small cracks and the actual sealing process.

A clean surface is required for the sealant to adhere. That’s where the broom comes into play. Where you’ve used the weed killer, remove the dead weeds. Sweep the driveway clean of any rocks, stones or dirt. Alternatively, you can use a leaf blower to blow the dirt and debris away. 

Filling the Cracks

Using the crack filler, fill the 1″ to 2″ wide cracks in the driveway. Take care not to use too much product as any bumps it creates will show through the sealant. You can use a scraper to level the filler if necessary to make it smooth and flush. Let the crack filler dry completely for 6 -8 hours before applying the sealant. 

After the resealing is done, it would be a good idea to use preventative measures to avoid new cracks from forming.

Use Your Driveway Sealer

Now it’s time to apply the driveway sealant. Make sure to mix the sealant by turning the tubs upside down before opening them.

Use the paintbrush to do the end of the driveway first. This ensures a seamless finish along the edge that lays against the garage or house. After that, pour the sealant in small sections across the width of the driveway and use the squeegee to spread the sealant evenly.

Use consistent pressure to ensure an overall seamless finish. Let the driveway cure for 24 hours before applying a second coat if needed. 

Things To Remember

Using driveway sealer yourself to fill minor cracks can be an easy way to increase the life of your driveway. Keep in mind that due to the multiple drying times involved, this job is best done in a warmer, more moderate time of year.
