The purpose of this study is to evaluate bond strength between sulfur polymer coating material and old concrete. Two kinds of spray casting methods are selected and compared to its bond strength by conducting bond test and measuring available casting time. As a result, the bond strength and available casting time is considerably depends on spray casting method.
