In order for the seal coat or surface treatment to be applied as planned, it usually requires three inspectors. The application of the seal coat is a fast-paced process, and requires alert inspectors to ensure that it is done properly. The inspectors must work together as a tightly knit team, because it is difficult to monitor every detail. If one inspector misses a detail, one of the others must pick it up. Communication and coordination must be excellent.
