After a year of testing by the students and faculty at Santa Anna College, MicroGuard® AD00 was selected and applied to all exterior and bathroom walls. The college, located next to graffiti prone neighborhoods south of Los Angeles, was experienced nightly graffiti paintings and was using aggressive measures to remove it at the expense of the surface aesthetics. AD00 was the solution and permitted easy removal with green cleaners time after time. The college reported areas that used to be hit weekly remained clean once the graffiti artist realized their work would not stand and was easy to remove.
