The structure was constructed in the 1960’s with exposed aggregate precast concrete panels. Over the years the concrete yellowed with age and darkened in appearance. Our approach was the determined how to clean the building with most effective yet least aggressive method. We tested our special apparatus that allows us to clean surfaces much butter than with a regular wand.

We essentially cleaned the entire building with water pressure only. This provided superior results while protecting the surrounding landscaping and pedestrians. Note that evidence of previous signage is removed.
