Epoxy and cement grout are two popular options when it comes to grouting tiles. But what exactly is the difference between the two, and which one is better for your project? Here’s a detailed comparison of epoxy vs. cement grout to help you decide.
What is Epoxy Grout?
Epoxy grout is a two-part grout made from epoxy resins and a hardener. When mixed together, these components form a durable, adhesive grout perfect for tiles.
Here are some key features of epoxy grout:
- Extremely durable and stain resistant – Epoxy grout forms a plastic-like seal on tiles, making it waterproof and resistant to cracks, chips, and stains from grease, oil, and dirt. This makes it a great choice for kitchens and bathrooms.
- Available in multiple colors – While cement grout is limited to neutral shades, epoxy grout comes in a wide range of colors from bright white to charcoal black. This allows you to match or accent your tile color scheme.
- Requires less maintenance – The impervious seal of epoxy grout prevents the growth of mildew and bacteria. You don’t have to seal it annually like cement grout.
- Long lifetime – With proper installation, epoxy grout can last decades without needing repairs.
- Minimal shrinkage – Epoxy grout does not shrink as it dries, reducing the chances of cracks forming.
However, epoxy grout also has some downsides:
- Difficult to install – Epoxy grout requires more precision to mix and install correctly according to manufacturer specifications.
- Expensive – The cost of epoxy grout per square foot is significantly higher compared to cement grout.
- Can be brittle over time – Extended exposure to heat and UV rays can cause epoxy grout to become brittle and prone to cracks.
What is Cement Grout?
Cement grout is a mixture of Portland cement, fine aggregates like sand, and color pigments. When water is added, it creates a paste that can be pushed into the seams between tiles.
Here are some key features of cement grout:
- Very affordable – Cement grout costs only a fraction compared to epoxy. This makes it ideal for large tiling projects.
- Easy to install – Cement grout only requires basic mixing with water and can be easily applied. Minimal skill is required.
- Matches tile texture – Cement grout is porous and mimics the texture of the tiles. Epoxy grout has a smooth plastic-like finish.
- Can be pigmented – Cement grout can be pigmented to any color. Although the color range is not as wide as epoxy grout.
- Environmentally friendly – Cement grout uses natural ingredients and is more eco-friendly compared to chemical epoxy resins.
However, cement grout also has some disadvantages compared to epoxy grout:
- Not waterproof – Cement grout is porous and can allow water seepage, leading to mildew and tile damage over time.
- Prone to cracking and shrinking – As cement grout dries, it tends to shrink and crack. This provides an entry point for dirt and stains.
- Requires more maintenance – Cement grout needs to be sealed once a year to prevent absorption of grime and oils.
- Limited stain resistance – Stains from dyes, grease, and dirt can easily penetrate into cement grout.
- Shorter lifespan – Cement grout may need repairs after 5-10 years due to cracking and crumbling.
Epoxy vs. Cement Grout Comparison
| Feature | Epoxy Grout | Cement Grout |
|-|-|-|
| Cost | Expensive, approx. $5-$10 per sq.ft | Very affordable, approx. $0.50 per sq.ft |
| Durability | Extremely durable for decades | Prone to cracks and erosion over time |
| Stain Resistance | Excellent resistance to stains | Can easily absorb stains |
| Installation | Requires precision mixing and skill | Very easy to install |
| Maintenance | Little required | Needs yearly sealing |
| Appearance | Wide range of colors, smooth plastic finish | Limited colors, matches tile texture |
| Lifespan | 20-30 years | 5-10 years |
| Moisture Resistance | Waterproof | Absorbs water over time |
When to Use Epoxy Grout
Here are some situations where epoxy grout is the best choice:
- Kitchen backsplashes – Since epoxy is stain-proof, it’s ideal to prevent absorption of oils and spices.
- Showers and baths – The waterproofing ability resists mildew and dampness.
- Floors with heavy foot traffic – The durability prevents chips and cracks under high impact.
- Stone and glass tiles – Stones and glass need maximum bonding strength to avoid cracking.
- Colored grout – Vibrant custom colors are only possible with epoxy grout.
- Countertops – For bar tops or worktables, epoxy provides enhanced stain and scratch resistance.
- Swimming pools and fountains – The high moisture resistance prevents erosion and staining.
When to Use Cement Grout
Cement grout works best in these use cases:
- Small bathrooms – For powder rooms or half-baths that see limited use and moisture.
- Floors with low traffic – Bedrooms or living rooms that do not need heavy-duty grout.
- Neutral colored tiles – If you do not require custom grout colors.
- Outdoor patios – Cement grout holds up well against the elements.
- Indoor walls – Areas not exposed to significant moisture or stains.
- New installations – Cement grout keeps installation costs low.
- Renovation projects – Old cement grout is easily replaced with new cement grout.
Tips for Choosing the Right Grout
When trying to choose between epoxy and cement grout, keep these tips in mind:
- Consider the application – Kitchens and bathrooms with stone tiles warrant epoxy grout. For walls or outdoor areas, cement grout will suffice.
- Think about appearance – For a bright white grout line or vibrant colors, choose epoxy grout.
- Factor in installation method – If you are uncomfortable mixing and applying epoxy, use simple cement grout.
- Evaluate maintenance requirements – Epoxy grout needs almost no maintenance compared to yearly sealing of cement grout.
- Look at cost per square foot – The price difference between the two is generally around $4-$5 per square foot.
- Check manufacturer recommendations – Some natural stones, like marble, require only cement grout.
- Hire a professional – For large commercial projects, specialized epoxy grout installation is recommended.
Conclusion
While epoxy grout clearly provides better performance and longevity, cement grout is the more economical choice for many homeowners and tilers. Consider the pros and cons carefully and evaluate your unique needs. In bathrooms, kitchens, and laundry rooms exposed to high moisture, the added cost of epoxy grout can be justified to get maximum stain protection and longevity. For simple renovations or outdoor patios, affordable cement grout is often the best option. With this overview of the critical differences between epoxy vs. cement grout, you can make an informed decision for your next tiling project.
