Quick Answer: When Should You Seal A New Asphalt Driveway

Apply sealant every three to five years. If you’ve recently installed a new driveway, wait at least 90 days to a year to ensure the sealant doesn’t damage the asphalt. Sealcoating a new driveway too early may trap oils within the asphalt, resulting in a driveway that is too soft or flexible.

Is oil based driveway sealer better?
