IMI Webinar Series - Tile Grouts and Expansion Joints
The performance and longevity of any tile installation depend on choosing the right grout, designing effective joints, and maintaining the assembly over time. Explore the grout categories defined in ANSI A118 standards, including Standard Cement, High Performance, Epoxy, and Premixed Grouts. Each type offers distinct characteristics that affect color consistency, cleanability, abrasion resistance, and durability. We’ll also look at how grout selection influences both performance and aesthetics, from color choice and joint width to alignment and layout. Learn the expansion joint requirements outlined by the Tile Council of North America (TCNA), including best practices for spacing, perimeter detailing, and movement accommodation. Finally, review recommended maintenance procedures, from initial cleaning and grout haze removal to sealer application and routine care, to ensure lasting performance, safety, and visual appeal.
Learning Objectives:
- Identify grout types in ANSI A118 and explain how proper selection prevents moisture issues and supports occupant health and safety.
- Discuss how grout selection, color, and joint width impact the performance, appearance, and long-term serviceability of tile systems.
- Explain how correctly detailed expansion joints prevent cracking and trip hazards while maintaining tile stability.
- Describe cleaning and maintenance practices that improve indoor health, reduce slip risks, and extend system durability.
