Learn the parameters that surround and affect decisions on historic masonry surface treatment, including patina, soiling, weathering, cleaning, and matching – before and during the project. These include aligning the purposes of cleaning with expectations, who makes decisions and when, applicable standards, methods of specifying cleaning, developing a cleaning plan, and field considerations like sequence of work, environment conditions, protection, and field testing and mock-ups. We’ll discuss currently available treatment including water, misting, detergents, chemical, biocides, poultice methods, micro-abrasive systems, mechanical hand tool methods, and laser. Walk away with an understanding of how to select the method(s) appropriate for your projects.
