This is a case study of photocatalytic coating on the exterior walls of a detached house (anti-soiling measures).
The decomposition of organic dirt using photocatalysts and self-cleaning will break down the substances causing dirt on the exterior walls of residential houses, allowing them to be washed away by rain and creating a clean environment.
We will apply a photocatalyst coating for exterior surfaces. When it rains, the coated surface becomes hydrophilic, enabling the decomposition of organic dirt and providing a self-cleaning effect. The rain helps wash away dirt, effectively contributing to the anti-soiling measures for the building's exterior. It is also effective in reducing cleaning and maintenance costs.

basic information
● The construction will use a low-pressure hot air painting machine specifically designed for photocatalysts to minimize paint loss and ensure efficient application. ● A photocatalytic aqueous solution (titanium dioxide solution) specifically for exterior use will be applied as a coating. ● For organic surfaces such as painted areas, a primer will be coated in advance to prevent degradation of the surface due to photocatalysis. ● Different primers will be used for coating surfaces that are water-absorbing and water-repellent, respectively. ● When rain hits the photocatalytic surface, it creates a hydrophilic surface (self-cleaning effect) and decomposes organic dirt, resulting in a clean environment. ● This will be effective in reducing cleaning and maintenance costs.
