This study aims to clarify a relationship between the degradation of exterior finishing and carbonation progress of concrete. The degradations of exterior finishing of reinforced concrete multi-family dwellings were investigated from the view point of cracks of coating systems and air permeability of finished concrete. The progress of the cracks was simulated based on Markov Chain Model.On the other hand, good relations were found on the carbonation progress, air permeability of concrete and cracks of finishing. Based on these findings, authors proposed a service life of the finishing from the view point of protection of concrete against carbonation.
