This paper is a experimental study to make clear about the relation between removement conditions and the environment condition and the inspection precision about the finish of external wall. On the thermography method. Author did outdoor experiment, using the examination wall which has artificial removements which changed the thickness of removements, the thickness of mortar finish, the area of removement. Author classed the easiness of distinction into 5 degrees for each removed part on the thermographs. And author considered each relation about the change of the precision along time, the difference of temperature between the removed part and the sound part, the solar radiation , and the temperature of outdoor air. When the thickness of removement and the removed area were larger, and the thickness of mortar was smaller, it became more easy to distinguish the removed part. As for the removement without air space to the back, it wasn't possible to distinguish. In the daytime the temperature was higher at removed part than the sound part, and in the night it became opposite. At the wall which receives the solar radiation, the temperature difference between the removed part and the sound part was larger in the daytime than in the night. However, to distinguish the removed part on the thermograph, it needed about 1.0℃ or more between the removed part and the sound part at the daytime, whereas it needed about 0.5℃ or more than at the night. Therefore in the night, it was easy to distinguish in the smaller temperature difference. In several conditions, the thickness of the mortar had the largest influence on this experiments.
