Masonry Cleaning Approach and Methodology - 1 LU/HSW

Tuesday, June 15, 2021 | 12:00 - 1:00 p.m. Eastern Daylight Time

Presented by: IMI

This presentation considers several parameters that surround and affect decisions on historic masonry surface treatment, including patina, soiling, weathering, cleaning, and matching - beforehand 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 such as sequence of work, environment conditions, protection, and field testing and mock-ups. A general overview of currently available treatments will be presented: water, misting, detergents, chemical, biocides, poultice methods, micro-abrasive systems, mechanical hand tool methods, and laser. Understand how to select the method(s) appropriate for the project.
 
 Learning Objectives:
  • Participants will have an introductory knowledge of historic masonry materials, their properties, and use in exterior construction.

  • Participants will gain insight into the more common types of soiling and deterioration phenomenon and specific intervention methods and materials.

  • Participants will be able to identify types of appropriate cleaning methods and repairs for potential testing programs.

  • Participants will be able to define appropriate methodology, field and environmental considerations, and specifying historic masonry cleaning projects.
