The asphalt temperature must be at or above 55°F in order for the sealer to adhere. Typically, early/mid-April through early October is the sealing season. Don’t wait until it’s too cold at night to seal! Once the temperature starts to get chilly and dip below 55°F at night for an extended period of time, it is too late to seal, and the product will not adhere properly – resulting in peeling.
