The forces of nature do their best to break down asphalt, creating cracks and potholes. Repairing driveway cracks is a lot simpler than you may think.
Cracks up to one inch wide can be repaired with a pourable or tubed asphalt patch product. (Note that a tubed product requires a caulk gun for application.)
During the drying process, the filler may soak into the crack and may need a second coat. Allow the crack to dry 24 hours before applying a second coat.
In addition, you will need to wait at least 24-48 hours before driving or walking on the repaired area to allow the material to dry. The product may take up to 6 months to fully cure.
