Epoxy grout is a high-performance, durable grouting material used primarily in tile installations where maximum strength, stain resistance, and chemical resistance are required. Unlike traditional cement-based grout, epoxy grout is made from epoxy resins, hardeners, and fillers, making it non-porous and extremely tough.
Key Properties of Epoxy Grout
Feature Details
Composition Epoxy resin, hardener, and filler powder
Water Absorption Very low (non-porous)
Chemical Resistance High (resists acids, alkalis, and solvents)
Stain Resistance Excellent; ideal for kitchens, bathrooms, and industrial areas
Bond Strength Very strong; adheres tightly to tile edges
Color Retention Superior; does not fade or discolor easily
Flexibility Good flexibility; resists cracking under movement
Curing Time Typically longer than cement grout; full cure in 24–72 hours depending on brand and temperature
Where Epoxy Grout Is Commonly Used
Commercial kitchens (due to stain and chemical resistance)
Bathrooms and showers
Swimming pools
Hospitals and laboratories
High-traffic areas (airports, malls)
Industrial floors (exposed to chemicals or heavy machinery)
