No. You cannot use asphalt products on concrete driveways. To seal a concrete driveway, use acrylic, epoxy, polyurethane, silane, siloxane, and silicate sealers or deep penetration sealers made specifically for concrete. Meanwhile, asphalt sealers contain refined coal tar (asphalt emulsion), water, sand, clay, polymers, and additives and are incompatible with concrete’s surface texture and higher density.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

When hiring an asphalt paving contractor to install your driveway, ask as many questions up front as possible. Here are a few questions to ask a prospective driveway contractor:

• How many years of experience do you have?

• Are you licensed, bonded, and insured?

• Do you have worker’s compensation?

• Do you use subcontractors on your projects?

• Do you clean up after the job is done?

• Who is responsible for any damage to lawn or landscaping?

• Do you provide a guarantee or warranty on your work?

• Do you give free estimates?

• What is the timeline for completion?

• How do you handle change orders?

• Can you provide at least three references?

• Can I see some of the work you’ve done?

The best time to seal a driveway is during periods of mild, dry weather, typically from late spring through early fall. For the sealant to bond and cure properly, it needs warm conditions. Avoid sealing in the winter when temperatures are too low.

For optimal results, follow these guidelines:

• Temperature: Apply sealant when air and surface temperatures are consistently above a minimum of 50-55°F. The ideal range is often between 60°F and 80°F. Avoid applying sealer in extreme heat (above 90-95°F), as it can cause the sealant to dry too quickly and improperly.

• Weather: Choose a time with no rain in the forecast for at least 24 to 48 hours after application. Rain can wash away the sealant before it has fully cured.

• Timing and Cost: While spring and fall offer ideal temperatures, they are also the busiest seasons for driveway sealing companies, which may lead to higher costs due to increased demand. The best specific month will depend on your local climate.
