Asphalt sealcoating is not meant as an effective treatment for cracks any larger than 1/8th inch wide. Parking lot and driveway cracks any wider than 1/8th inch should be treated separately with a special material called crack sealant before sealcoating can be applied.

Sealant should be applied soon after the crack has been routed and cleaned with the hot-air lance. Air temperature, AC surface temperature and humidity all need to be considered during the product installation. Route and seal should not be applied following a rain event. The pavement must be as dry as possible.

Approximately 75% of cracks in asphalt pavement form into potholes within 3 years if they are not sealed. In drastic comparison, only approximately 1% of cracks that have been sealed will form into potholes within 3 years.

Hot pour crack filling and sealing is generally done on roads and highways and in many cases, on parking lots. Hot pour offers the advantage of quick set times (10 minutes or less). Once the hot pour material cools you can drive on it.

Crack sealing is the process of placing an adhesive sealant into cracks on the pavement surface, preventing the infiltration of moisture and non-compressible materials into the pavement.

Crack sealing is a more costly procedure for the pavement owner but provides substantial value due to its long life expectancy. While crack filling may only last one or two seasons depending on the cracks activity, crack sealing can last up to 8 years or more and is considered a permanent treatment.
