Fred, Very timely post! We just paved our driveway this summer and Iâve been asked several times by folks in the neighborhood when we should seal it. The company I work for has an entire paving division so I asked the experts and they all agreed that you need to wait at least 90 days.
When you do seal the driveway, use a high-quality coal-tar based sealer. These typically should be applied every 3 to 5 years. The driveway should be sealed when either the original black asphalt has worn off the stones or the subsequent coat of sealer has worn off revealing the actual pieces of stone aggregate.
