In this program, participants will gain a comprehensive look at the tools and techniques of cleaning historic architecture. Learn how “Restoration Cleaning” categorizes types of contaminants and how it compares and contrasts abrasive, water and chemical cleaning. The program concludes with 10 “must know” tips for successful restoration cleaning.  


Learning objectives include:

  1. Identify 4 levels of contaminants
  2. Explain the 3 main methods of restoration cleaning.
  3. Name the 4 main types of chemical cleaners.
  4. List 10 tips for cleaning historic buildings.


Additionally, this course will provide architects, engineers, designers and specifiers with the necessary tools to make an informed selection and specification of the demonstrated materials for the repair of masonry. The preservation of existing concrete and masonry facades will also be discussed and actual applications for a variety of masonry repair methods will be demonstrated. 


Learning objectives include:

  1. Understand the process of evaluating and determining the material selection process for the preservation of concrete and masonry facades.
  2. Service, performance and constructability issues will be analyzed, and then balanced by the owner and engineering requirements.
  3. This course will review the different types of masonry coating technologies, analyze their benefits and allow for informed selection.
  4. Proper preparation of the substrate, bonding procedures, finishing for vertical repair, color matching and crack repair will be demonstrated to promote structural integrity.
