  • How often should I have my driveway sealcoated?
    In general, asphalt should be sealed every-2-3 years to get the maximum life. Maintenance interval will depend on wear, traffic, weather, spills, etc.
  • How long should I wait before having my new driveway sealed?
    It is usually best to allow new asphalt to cure 1 year before it is sealed.
  • Do I have to be home on the day my driveway work is scheduled?
    No, as long as the driveway is clear of all vehicles and obstructions, Supreme Seal can complete your job and send you an invoice in the mail.
  • How long should I stay off the driveway after it is sealed?
    You are advised to stay off the surface of your driveway for 24-48 hours after application. Actual drying time will depend on the weather, humidity and sunlight. Shady areas will take a little longer.
  • Will Supreme Seal secure my driveway after sealcoating?
    Yes. Supreme Seal will tape off the entrance of your driveway to prevent inadvertent use while you are gone.
  • Can I water the lawn after application?
    Be sure to turn off all automatic sprinkler systems and do not water the lawn next to the driveway for 24 hours before and 24 hours after application as the water will discolor the new surface.
  • Anything else I should watch out for?
    Chemical fertilizer has been found to cause staining of partly cured seal coat. Do not fertilize your lawn or garden 2 weeks before or after seal coating.
