Newly paved asphalt surfaces should not be sealcoated until they have sufficient time to cure. Curing allows the excess oils that are always present in new asphalt pavements to diminish through a process called oxidation. This process can take 6-12 months, depending on the percentage of oil present in the new pavement. We usually recommend that a new asphalt pavement cure one year. This ensures that the surface will be properly cured when pavement sealer is applied.
