To preserve your new driveway or commercial parking lot, it is advisable to seal coat it after it has been paved. Count on international Paving for a professional job. The best time to seal is 3-12 months after it has been paved, and every 2-3 years thereafter depending on traffic wear conditions . Because blacktop is naturally porous, water can seep into and through the paving. This not only causes deterioration, but also results in ridges and upheaval due to frost and freezing. Blacktop is also softened and broken up by gasoline, lube oil, grease, road salts and anti-freeze that drip from cars. Sealer protects asphalt surfaces with a coating that is impervious to these harmful elements. Unprotected pavements remain porous, dry out, become rough, and lose their life rapidly.
