Brick Building
This building was Photo-Catalyst TiO2 treated in year 2000.
The surfaces were pristine clean after 3+ years of exposure to pollution from autos and trucks on this high traffic city street.
The above picture is of the adjacent building on this busy street. Note the amount of dirt that is on the front surface of the building compared to the Photo-Catalyst TiO2 treated building. The owners of the treated building are very pleased with the results and performance of the TiO2 treatment. As you can see, it greatly enhances the appearance of their building.
