What is Epoxy Grout and Why is it used for Tile Joints?
Mar 3, 2025

Noticed how the grout between your bathroom tile joints tends to darken over time, no matter how much you clean? These are cement-based grout that, while essential for holding tiles together, are naturally porous. This means it can absorb moisture and dirt, which may lead to stains, mildew and gradual wear over time.
That is where epoxy grout makes a difference. With its non-porous, stain-resistant, and waterproof properties, it keeps your tiled spaces looking fresh and flawless with minimal upkeep. But what exactly sets it apart from traditional grout, and what are the benefits of epoxy grout?
What Is Epoxy Grout?
Epoxy grout is a high-performance grouting material made from epoxy resins and hardeners, unlike traditional cement-based grouts. Epoxy grout forms a waterproof, chemical-resistant bond that effectively seals tile joints. Epoxy grout is used for tile joints in areas exposed to moisture, stains, and heavy traffic. Epoxy grout is ideal for kitchens, bathrooms, swimming pools, and commercial spaces where durability and hygiene are essential. Now that we know what is epoxy grout, let’s understand how epoxy grout differs from cement grout.
Cement Grout vs. Epoxy Grout
Traditional cement grout is a mixture of cement, sand and water. While affordable and easy to apply, it is porous, which requires regular sealing to prevent water penetration and staining. It is also susceptible to cracking and deterioration over time, particularly in high-moisture environments.
Epoxy grout, by contrast, creates a non-porous, waterproof seal that resists stains, chemicals and bacteria. Though slightly expensive initially, epoxy grout eliminates the need for periodic sealing and offers superior longevity. The application process is more demanding than cement grout, which requires precise mixing and quicker application before the epoxy grout begins to set. However, the trade-off in durability and reduced maintenance makes epoxy tile grout cost-effective in the long run.
Advantages of Epoxy for Tile Joints
These are the benefits of epoxy grout that make it worth considering for your tiling project:
-
Superior stain resistance
Unlike porous cement grouts, epoxy for tile joints won’t absorb coffee, wine, oils or other common household stains.
-
Waterproof properties
Epoxy for tile has a non-porous nature and prevents water penetration, which makes it ideal for wet areas like showers and swimming pools.
-
Enhanced durability
Epoxy grout resists cracking, shrinking and deterioration, maintaining its integrity even in high-traffic areas.
-
Chemical resistance
Epoxy for tile withstands exposure to cleaning chemicals, making maintenance easier without compromising the grout’s integrity.
-
Antimicrobial properties
Epoxy for tile is a non-porous surface that inhibits mould and mildew growth, contributing to a healthier environment.
How to Apply Epoxy Grout for Tiles?
-
Preparation
Ensure tile joint surfaces are clean and dry. Mix the epoxy components according to manufacturer instructions. Typically, epoxy resin is mixed with a hardener to create a chemical reaction that cures the material.
-
Application
Using a rubber float, apply the grout diagonally across tile joints, which ensures complete filling. Work in small sections as epoxy sets faster than cement grout.
-
Initial Clean-up
After about 20-30 minutes (follow specific product guidelines), use a damp sponge to remove excess grout from tile joint surfaces. Rinse the sponge frequently and change water as needed.
-
Final Clean-up
Once the epoxy tile grout has cured for 24 hours, remove any remaining haze with a clean, dry cloth. For stubborn residue, use an epoxy haze remover recommended by the manufacturer.
