Well, that will account for maybe 5 days a year. So when is the best time to do sealcoating? What is the most perfect time to sealcoat any asphalt surface?
Here are some basic standards:
Sealer is to be applied in temperatures 50 degrees or better over a 24 hour period.
Area needs to dry and free of wet conditions such as rain, fog, or overcast days with high relative humidity.
No standing water.
If temperature is over 90 degrees, the asphalt needs to be cooled immediately prior to sealer application.
