Football is back, the kids are in school, the air is getting cooler and … Shoot! You forgot to get the parking lot sealed at your store. This is the time of year when we often get calls asking, “Is it too cold outside to sealcoat our asphalt parking lot?”
Asphalt sealcoating season is from May – October in Ohio. May is when the pavement and air temperature are warm enough to allow the sealcoat to adhere. By November, the air temperature is typically too cold at night to allow enough time for the sealcoat to cure properly. It’s also important to consider weather conditions: Ideally, it’s best to sealcoat on a sunny, dry day.
Ideal sealcoating temperatures are between 40 to 95 degrees. And the temperature needs to stay above 40 degrees for at least 48 hours following the sealcoat. This is because the sealcoat needs time to cure. If the temperature drops below 40 degrees before the sealcoat is cured, the likelihood that it will wear off within the next year increases. A typical sealcoat should last three to four years – or longer – depending on traffic. Here is more information on signs it’s time to sealcoat your parking lot.
Customer satisfaction is our goal every time. That is why we typically do not sealcoat asphalt after October in Ohio, pending on the weather. The chances that the sealcoat will wear off is too high after this date and that’s not good for the parking lot’s longevity, you, or our customer satisfaction and retention.
If an asphalt contractor in Columbus, Ohio offers to sealcoat your parking lot after temperatures have dipped below 40 degrees, we recommend getting a signed, 1-year warranty on the condition of the sealcoat.
