A lthough the crew wanted to remove all dirt and grime from the exterior of the building, they did not want to remove the existing coating. According to Claus, the existing coating was to be encapsulated within the new coating system. Tis helped to keep the job green, as disposal of the old paint was not necessary. "We used a 1,200 psi [8,273.7 kPa] pressure washer that didn't disrupt the bond of the previous coating to the stucco substrate," stated Claus. Claus and Angelus CEO Shaun Geiger are quick to point out that all water was collected and pumped into a holding tank where it was then taken to a facility for proper disposal per environmental regulations. "We use a specialized service called Enviroserv to properly sort and dispose of all waste products that are generated from our work, including wastewater. We have a program in place for waste management that aligns with our clean, green strategy," stated Geiger. The crew performed most work from scaffolding, so harnesses and safety lines were used. The 8- to 14-person crew also wore hard hats and safety vests at all times and gloves and goggles when necessary.
