落書きの実態と建築材料の落書き除去性に及ぼす試験条件の影響 : 建築材料の落書き除去性評価方法に関する研究(その1)

Abstract

To establish the evaluation method for removability of graffiti on the building materials, following two investigations was carried out. One is, the actual condition of graffiti was investigated at 20 parks in Funabashi-city. Other one is, the effects of test conditions were examined on the removability of graffiti. In the parks, the graffiti were almost colored with black, blue, red and white of paint and marking pen. The graffiti was written on test material in paint or a marking-pen. The graffiti on test materials was removed by rubbing with a dry cloth while spraying ethyl alcohol.
