Epoxy and cement-based grout fill the joints between tiles, but they differ in composition, performance, price, and installation. The best choice depends on the room, expected exposure, tile, joint size, and project budget.
Five facts about epoxy grout
- It is made from epoxy resins, a hardener, and aggregate or filler.
- It is highly resistant to water and stains, making it well suited to many wet or demanding areas.
- Its dense surface does not rely on the same routine sealing schedule as typical cement grout.
- It is generally more expensive than cement-based grout.
- It sets differently and can be less forgiving to install, so careful mixing, timing, and cleanup are important.
Five facts about cement-based grout
- It is commonly made from cement, water, and sand or other fine aggregate.
- It is widely available and is used in many residential and commercial tile installations.
- It is usually less expensive and more familiar to installers.
- Because it is porous, it can absorb moisture and stains unless it is properly maintained and sealed where appropriate.
- It is available in sanded and unsanded formulations for different joint widths and tile applications.
Side-by-side considerations
| Factor | Epoxy grout | Cement-based grout |
|---|---|---|
| Water resistance | Very high | More porous; sealing may be recommended |
| Stain resistance | Very high | Varies with product, sealing, and maintenance |
| Durability | Strong and resistant to many chemicals | Reliable when correctly selected, installed, and maintained |
| Cost | Usually higher | Usually lower |
| Application | More time-sensitive and demanding | More familiar and generally easier to work with |
Which grout should you choose?
Epoxy grout can be a strong choice for showers, kitchens, and other locations where water and stain resistance matter. Cement-based grout remains a practical, economical option for many installations. A tile professional can assess the existing surface, movement, moisture, and finish requirements before recommending a material.
