The first application of sealer on a new driveway should occur around one year after installation. This will allow some of the new oils to evaporate and promote good sealer adhesion. The very first application of sealer may only last one to two years as the new asphalt will soak in the first coat of sealer. Thereafter, we recommend sealing every two to three years. In most cases, it is unwise to seal a driveway every year as you can build up too much sealer which can lead to surface cracking of the sealer. Some poorly laid or older asphalt driveways need sealing every 1-2 years to prevent additional cracking and pot holes. Cracks and pot holes should be filled and repaired every year.
