Depending on the preparation time of the floor and coatings used, approximately 2-3 days to completion. A typical system must be traffic free (foot) for no less than 24 hours after final coat, and, 5-7 days before vehicular traffic depending on weather conditions and coating systems used. The system is an epoxy coating needing time to cure and fully harden, allowing something heavy to be driven over and if parked prematurely may result in damage to your new floor.
