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.

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.

Apply either one or two coats, depending on the manufacturer’s instructions.
