In Japan today, pets such as dogs and cats are kept indoors. Countermeasures against indoor pollution and maintenance of sanitation environment are important in response to rising awareness of living environment with pets. We focused on the problem that interior wall materials are damaged by pet scratching. The purpose of this study is to examine the relationship between the physical properties and visual qualities of plaster-patterned (Hikizuri) wall material and scratches. The influence of factors such as the scratch direction of the wall on impression reduction is clarified by sensory evaluation, and used as basic data for building material development with the less repairing.
