Driveway Sealcoating questions, answered by experts
Oil-based sealers generally offer longer results for driveways in cold climates. If you experience extreme temperatures, oil sealants offer a level of flexibility that makes them expand and contract along with the freeze-thaw cycle instead of cracking.
New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.
During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.
The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.
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.
Sealcoating asphalt costs$0.14 to $0.25 per square foot. Doing so prevents erosion in harsh weather and keeps your asphalt from cracking or getting potholes. It’s a good idea to hire a professional sealcoating company with positive reviews to do this work rather than do it yourself.
There are more pros than cons, but there are a few disadvantages to sealing your driveway to be aware of. Sealant can make the surface slippery, which can be a hazard, especially when the driveway gets wet. Look for sealants with abrasive additives to help counteract this. You’ll also need to remember to reapply your sealant every two years and budget for the expense that comes with it.
