The fresh sealer must remain blockaded and allowed to cure for approximately 24 hours depending on the weather conditions. In certain situations, our staff can apply more latex modifier a faster drying application that can be driven on sooner. Sometimes immediately following a sealcoating project, vehicles may leave scuffs or "power steering marks". This usually happens when a driver vehicle backs out of a parking stall, stops, and turns the steering wheel while standing still. These marks wear out in a week or two and should not require any additional work.
