This paper describes a detection method of two types of exfoliations for outward tile wall. One of the tile exfoliations is an outer exfoliation separated the tile surface from mortar concrete, the other is an inner exfoliation deteriorated space between the substrate and mortar concrete. In order to research these exfoliations, we focused attention on the wavelet analysis that enables to analyze the frequency element of a waveform on time phase continuously. In part 2 of this study, comprising the conventional detection methods in which the inspection robot was applied and new method used by wavelet analysis, the characteristics of these methods were verified respectively. As a result, it found that the peak rate method detected outer exfoliation, the cross correlation method detected inner exfoliation and that the wavelet method detected this exfoliation instantly. A best effective detection flowchart inspected the tile exfoliations to apply to the inspection robot was proposed.
