Choosing the right grout can make a big difference to the appearance, durability and maintenance of tiled surfaces. Two common options are epoxy grout and cement grout.
While both are used to fill the joints between tiles, they have different properties. Epoxy grout is known for its strong resistance to water, stains and chemicals, while cement grout is widely used because it is affordable and easier to apply.
So, which one should you choose?
The answer depends on where the grout will be used, how much moisture and traffic the area receives, your maintenance requirements and your budget.
In this guide, we explain the difference between epoxy grout and cement grout and help you understand where each option may be suitable.
What Is Cement Grout?
Cement grout is a traditional tile grout made primarily from cement, fine aggregates and other additives. It is mixed with water before application and is commonly used for residential and commercial tiling projects.
Cement grout is available in different colours and can be used for both floor and wall tiles.
How Does Cement Grout Work?
Cement grout is applied into the gaps between tiles. Once applied, it cures and forms a solid joint that helps keep tiles properly supported and prevents dirt from collecting in the open spaces.
Depending on the product and application, cement grout may require sealing to improve its resistance to moisture and staining.
Where Is Cement Grout Commonly Used?
Cement grout can be used for many general tiling applications, including:
- Bathroom walls and floors
- Kitchen walls and floors
- Living areas
- Bedrooms
- Residential floors
- Commercial areas
- Wall tiles
It is often selected when keeping the initial project cost lower is an important consideration.
What Is Epoxy Grout?
Epoxy grout is a two-component grout made using epoxy resin and a hardener, along with specially selected fillers and pigments.
Unlike traditional cement grout, epoxy grout does not rely on cement as its main binder. Once the components are mixed and cured, the grout forms a dense and durable joint.
Epoxy grout is commonly considered for areas exposed to moisture, stains, frequent cleaning or heavy use.
How Does Epoxy Grout Work?
Epoxy grout is mixed according to the manufacturer’s requirements and carefully applied into the tile joints.
It cures to create a strong grout joint with low water absorption. Proper surface preparation and application are important because epoxy grout can be less forgiving to work with than traditional cement grout.
Where Is Epoxy Grout Commonly Used?
Epoxy grout can be suitable for:
- Bathrooms
- Shower areas
- Kitchens
- Wet areas
- Commercial kitchens
- Restaurants
- Retail spaces
- High-traffic areas
- Commercial floors and walls
Epoxy Grout vs Cement Grout: Key Differences
Although both products perform the basic function of filling tile joints, their performance can differ considerably.
Water Resistance
One of the main differences is moisture resistance.
Epoxy grout has very low water absorption, making it suitable for areas that regularly come into contact with water.
Cement grout is more porous. Depending on the product, it may absorb moisture and may benefit from a suitable sealer, particularly in areas with regular water exposure.
For wet environments, epoxy grout can therefore be an option worth considering.
Stain Resistance
Epoxy grout generally offers better resistance to stains than standard cement grout.
This can be useful in kitchens, restaurants and other areas where the grout may come into contact with food, grease, dirt or coloured liquids.
Cement grout can become stained over time if it is not properly maintained or sealed.
Durability
Epoxy grout forms a hard, durable joint after curing. It can withstand regular cleaning and heavy use when correctly installed.
Cement grout can also provide good service, but it may be more susceptible to wear, staining and moisture-related deterioration depending on the environment and maintenance.
The actual lifespan of either grout depends on product quality, installation, tile movement, cleaning methods and the conditions of the area.
Cleaning and Maintenance
Epoxy grout is relatively easy to clean because its dense surface is less likely to absorb spills and dirt.
Cement grout can require more regular maintenance. Dirt can become embedded in its more porous surface, and some applications may require periodic sealing.
For properties where easy cleaning is a priority, epoxy grout may be more suitable.
Mould and Mildew Resistance
Moisture can contribute to mould and mildew growth around tiled areas.
Because epoxy grout absorbs very little water, it can help reduce the conditions that contribute to staining and moisture absorption within the grout itself.
However, grout alone cannot prevent mould throughout a bathroom or other wet area. Proper ventilation, cleaning, waterproofing and moisture control are also important.
Appearance and Colour Options
Both epoxy and cement grout are available in a range of colours.
Epoxy grout can provide a consistent finish because its colour is integrated into the grout mixture. Cement grout also offers many colour choices, although its appearance can change over time due to staining, moisture and cleaning.
The right colour depends on the tile design and the overall look you want to achieve.
Installation Process
Cement grout is generally simpler to mix and apply.
Epoxy grout requires more careful preparation and application. The working time can be limited, and excess material should be cleaned from the tile surface properly before it cures.
For this reason, professional installation can be particularly important when using epoxy grout.
Cost
Cement grout is generally less expensive in terms of material cost.
Epoxy grout usually has a higher upfront cost because of the material itself and the more specialised installation process.
However, the initial price is only one factor to consider. Maintenance requirements, cleaning and the expected service life can also affect the overall value of a grout solution.
