⚡ CalcWolf Insight

The best driveway sealing tip most people miss: clean the driveway with a pressure washer or strong detergent AND let it dry completely (24-48 hours) before sealing. Sealer applied over dirt, oil, or moisture peels off within a season. Proper surface prep is 70% of a good sealing job — the actual application is the easy part.
