To Coat or Not to Coat Existing Masonry Facades

Tuesday, May 9, 2023 | 12-1 p.m. Eastern Time

Coatings are often seen as a cheap, quick, and easy way to address aesthetic improvement, water infiltration, and other common conditions. Applying coatings to a masonry building prior to other critical repairs can lead to accelerated deterioration, irreversible damage, and more costly restoration. Identifying the appropriate coating for the type of masonry, wall construction, and conditions is a complex process.

Join us to gain an understanding of masonry properties, conditions, and their sources. Learn both appropriate and inappropriate uses of masonry coatings. For the circumstances where coating masonry is appropriate, you’ll learn different types of coatings, their properties, chemical composition, methods of application, and performance. You’ll also learn when it’s downright inappropriate to use a coating and when repairs are a more suitable solution.

 Learning Objectives:

  • Investigate the porosity and water absorption characteristics of masonry building materials.

  • Verify types of repairs that are critical to carry out prior to considering coating masonry.

  • Identify the conditions and circumstances that make it appropriate or not appropriate to apply a coating to a masonry substrate to ensure a high performing building.

  • Summarize good surface preparation methods for coatings and the maintenance required after a coating is applied to masonry.
