To Coat or Not to Coat: Evaluating Coatings for Existing Masonry Facades

Tuesday, July 7, 2026 | 12-1 p.m. Eastern Time
1 LU/HSW

Coatings can enhance the appearance and weather resistance of masonry facades, but their success depends on proper assessment, timing, and application. Explore how coatings interact with different masonry materials and wall systems and how environmental conditions influence their performance. Learn why premature coating applications, without addressing underlying repairs, can lead to accelerated deterioration and higher long-term costs. We’ll also review best practices for selecting compatible coatings, evaluating existing substrate conditions, and exploring alternative moisture mitigation strategies. By understanding the science behind coatings and their proper use, you’ll be equipped to make informed decisions that protect both the structure and its occupants.

Learning Objectives:

  • Describe common masonry wall types and explain how their construction methods manage moisture and vapor to maintain building health and durability.
  • Identify moisture-mitigation strategies beyond coatings that protect masonry facades from deterioration and safeguard occupant welfare.n.
  • Evaluate coating options for compatibility with masonry materials, environmental conditions, and long-term performance requirements.
  • Compare coating systems commonly used on existing masonry walls and assess their properties, advantages, and limitations in preserving envelope integrity.
