Practical study of tile finishing considered safety and the maintenance of beautiful exterior

Abstract

In actual building jointing photocatalyst by organic elastic adhesive, photocatalyst against contamination tile was tested for used state and contamination in passing of time. And, durability of photocatalyst ability was tested. Further, organic elastic adhesive was tested for mortal jointing method, comparison of working efficiency, and jointing durability. In researching after two years from worked, following was found.
1. In working ability, adhesive jointing method was superior to mortal jointing method.
2. In passing of time, changing of adhesive strength was small, and inferiority tendency couldn’t be confirmed.
3. Contact angle with water of photocatalyst tile was less than 15 degrees that is initial standard. And inferiority tendency couldn’t be confirmed.
4. Actual used condition, photocatalyst tile had sufficient ability against contamination.
