Epoxy adhesive grout is a high-performance grout made from a combination of epoxy resins and a hardener, often used in applications requiring superior bonding strength, chemical resistance, and durability. It's particularly common in industrial, commercial, and high-traffic environments.
🔧 Key Properties of Epoxy Adhesive Grout
Feature Description
High Bond Strength Forms a strong, durable bond to tile, stone, concrete, metal, and other surfaces.
Chemical Resistance Resistant to acids, alkalis, grease, and solvents—ideal for kitchens, labs, and industries.
Waterproof Non-porous and impervious to water; prevents mold and mildew growth.
Stain Resistance Easier to clean than cementitious grout—stains don’t penetrate.
Color Retention Maintains color without fading or discoloration.
Durability Withstands heavy mechanical loads and foot traffic.
Non-shrinking Maintains size and shape after curing—no cracking or shrinking.
🏗️ Common Uses
Commercial kitchens and food processing plants
Laboratories, hospitals, and clean rooms
Swimming pools
Industrial floors with chemical exposure
Wet areas (bathrooms, steam rooms)

Part C (optional): Filler (can be silica or color pigment, sometimes comes pre-mixed)
🛠️ Application Guidelines
Surface Preparation:
Clean, dry, and free of dust, oil, or contaminants.
Mixing:
Mix components (A + B or A + B + C) according to manufacturer instructions.
Use a low-speed mixer to avoid air entrapment.
Application:
Apply with a rubber float or trowel.
Press firmly into joints.
Cleaning:
Clean excess immediately with a sponge and water (before it sets).
Curing:
Cures within 24–48 hours depending on temperature and humidity.
⚠️ Precautions
Wear gloves and eye protection—epoxy can irritate skin and eyes.
Work in well-ventilated areas.
Once cured, it is difficult to remove—apply carefully.
More expensive and harder to work with than cement grout.
