Description: This session presents the rationale and methodology for cleaning both interior and exterior historic masonry surfaces. Cleaning can be the first type of repair measure performed on a new masonry structure to remove any construction residue. Cleaning can also be performed as part of a maintenance program or restoration project. In each of these instances, the masonry can be susceptible to damage caused by an improper selection of materials or methods. Understanding how to approach and develop a proper testing program is the first step in determining which technique will clean the building while promoting long-term performance. The program will introduce current cleaning systems and describe their general performance and applications. Specific attention will be paid to chemical, micro-abrasive, laser and latex systems.
Presenter: Roy Ingraffia, International Masonry Institute.
