Webinar Recording: Understanding the Causes and Significance of Facade Degradation


A recording of this webinar is now available.

Why has your building’s facade changed in appearance? Is discoloration or other visible degradation limited to an aesthetic concern or does it signal something more serious? What are the risks and can your facade be cleaned and/or repaired?

In this webinar, WJE petrographer George Reo and chemist Kimberly Steiner discuss the effects of chemical incompatibility, staining, and degradation on a variety of facade materials, including glass, stone, metals, and coatings. Illustrated by case studies, they describe typical field and laboratory investigation techniques and offer recommendations for reducing the risk of degradation in your building facades.

By the end of the webinar, you will be able to:

  • Identify the primary types of facade material failure due to chemical incompatibility
  • Explain how time affects material degradation
  • Describe various field and laboratory investigation techniques to assess your facade materials
  • Reduce the risk of degradation to your facade
