The best temperature range for applying sealcoat is between 55 and 90 degrees Fahrenheit. Ideal temperatures are those that start around 70 degrees Fahrenheit in the morning and increase throughout the afternoon.
You can apply sealer at any time of day as long as the pavement temperature does not fall past 40 degrees at night. You can even apply the sealcoat during the nighttime. Many people choose to start their sealcoat project around 10 AM as the sun's temperatures begin to rise, and the humidity is not too oppressive.
The best time to sealcoat your driveway is during summer when the temperature is above 50 degrees Fahrenheit. It's not advisable to seal coat in the winter as the colder season will negatively affect the performance of the sealer. The sealer may not bond with the asphalt or will not cure correctly.
Seal coating should not be done when temperatures are below 55 degrees Fahrenheit or above 90 degrees Fahrenheit. And you should never seal your driveway in either extreme cold or extreme heat because it will cause the material that has been applied to break down quickly.
Upon completion, we recommend to keep vehicles off for a minimum of 48 – 72 hours. You may walk on the driveway after 24 hours.
Sealcoating is not designed to be an asphalt crack filler, it is made for sealing the surface and protecting it from the elements such as UV light, salts and oils. It is not flexible enough to fill a crack without re-cracking and it does not have adhesion quality's that Asphalt Crack Filler has.
Driveways with many cracks take longer; the more cracks and the deeper the cracks, the longer it takes to cure. 4. Thicker coats slow dry time. We always recommend two thin coats for best results.
Make sure there's no forecast for rain for at least three days. You want the driveway to remain dry for at least one day before and one day after applying each layer of sealant. Opt for late spring, summer, or early fall to do this project.
Temperatures below 50 degrees Fahrenheit are too cold to apply sealcoat. Furthermore, if the low temperatures fall to freezing or below while the coating dries, water in the sealcoat material could freeze, leading to the finished product separating and peeling.
While slathering seal coat over asphalt in a thick layer can be tempting, a “more is better” approach is detrimental to the pavement beneath. Too much sealer can lead to premature cracking, which will shorten the lifespan of your driveway.
The best time to pave or seal a driveway is typically in the late spring or early summer. Cleaning and maintaining your driveway regularly can also help to prolong its life. It's essential to repair any cracks or damage as soon as possible to prevent further deterioration and higher pavement maintenance costs.
Apply sealant every three to five years. If you've recently installed a new driveway, wait at least 90 days to a year to ensure the sealant doesn't damage the asphalt. Sealcoating a new driveway too early may trap oils within the asphalt, resulting in a driveway that is too soft or flexible.
While sealing a driveway can be done with hand tools like shovels and push brooms, it's faster and easier with a few pieces of outdoor power equipment like a string trimmer, blower and pressure washer. It's also smart to wear old shoes, safety glasses, and a pair of gloves you won't mind parting with.
Industry standards recommend that you wait one year or go through one winter before you seal coat a new driveway. How often should I seal coat my driveway? Industry standards recommend every two years; allowing the sealer to wear away before you reseal the driveway.
It can take at least 24 hours for the driveway sealant to cure completely but if you give it 4 hours to dry it should be able to resist the rain and any possible damage that could occur.
The Drawbacks of Seal Coating
One is that it can be messy and difficult to apply evenly. It's also important to note that sealants will not repair significant damage to your driveway; they will only protect it from further damage. If your driveway is damaged, you'll need to have it repaired before sealcoating it.
When sealcoating is used as part of a preventative maintenance program, it can extend the life of your driveway by up to 20 years on average.
Squeegee applications typically produce a better bond between the pavement's surface and the sealant.
But if you want to drive on it, then you have to wait a minimum of 12 hours for it to dry and cure. If it's overcast or if rain is in the forecast, then the drying and curing process will definitely take much longer. For optimum results, we recommend that you use your driveway 48 to 72 hours after sealcoat was applied.
To apply the sealer, you will need a brush and a long-handled paint roller or squeegee. To save time and maximize coverage, we recommend using a long-handle paint roller that is 18” wide with a ⅜” nap roller.
Driveway Square Footage
A 500-square-foot driveway typically requires 5 gallons of sealant, which can run between $40 and $165.
In some cases, a residential driveway will only need one coat of sealant. However, if the asphalt sealcoating has never been sealed before, it may take a second coat to give it the rich, deep finish that most homeowners prefer.
