The objectives of this study were to evaluate the water transport resistance of exterior tile finishing based on experiments and the results of the experiments and to examine its performance of concrete structure protection and its behavior in moisture absorption environment, and ultimately, to establish a system for preventing the peeling and exfoliation of exterior tile finishing. We predicted the distribution of absorbed water diffusivity and change in stress development over time using finite factor analysis in connection to the absorption volume change rate and mechanical properties of exterior tile finish materials and concrete structures with the same mixing conditions. In order prevent the peeling and exfoliation of exterior tile finishing, we need to collect and analyze more accurate data on the mechanical properties of the materials of exterior tile finishing and bond strength among the materials, to formulate models through analyzing the data, to predict stress or deformation in real conditions using the models, and to develop measures in response to expected problems.
