Historic Terrazzo Installation & Repair

Tuesday, September 16, 2025 | 12-1 p.m. Eastern Time
1 LU/HSW

Cementitious terrazzo has served both decorative and functional purposes for centuries. This popular floor and wall finish is not only aesthetic but durable, resilient, easy to clean, and resistant to mold, bacteria, and chemicals. Learn about historic terrazzo's manufacture, installation, performance, and deterioration, along with restoration and repair methods. Since floor and wall materials typically experience the most wear in a building, maintenance and repair can differ from traditional methods. Learn long-lasting repair methodologies as we explore the evolution of terrazzo materials and current industry standards for installation.

 Learning Objectives:

  • Summarize historical methods of terrazzo mixing, setting, and finishing and how the materials and installation methods have changed over time.
  • Identify how terrazzo, both cementitious and resinous, is durable, resilient, and easy to clean.
  • Investigate how historic terrazzo surfaces can be renewed for a second life cycle and how to meet industry guidelines and standards when restoring them.
  • Explain and compare repair and maintenance methodologies of these materials and how to specify them.
