When embarking on a tiling project, choosing the right grout can make a significant difference in both the look and longevity of your tiles. At Plus Plumbing, we often get asked about the difference between epoxy grout and normal (cement-based) grout.

Both serve the essential function of filling spaces between tiles, but they differ greatly in terms of composition, durability, application, and maintenance. In this article, we’ll delve into the key differences to help you make an informed decision for your next tiling project.

What is Grout?

Grout is a material used to fill the spaces between tiles after they’ve been laid. It serves both aesthetic and functional purposes, ensuring tiles are aligned and providing stability. There are two main types of grout used in construction: cement-based grout, also known as normal grout, and epoxy grout.

Cement-Based Grout (Normal Grout)

Composition

Cement-based grout is made from a blend of cement powder, water, and often sand. The mixture is applied between tiles and then left to set. It’s the more traditional choice, used in many tiling projects for decades due to its ease of use and affordability.

Pros of Cement-Based Grout

1. Affordability: Normal grout is less expensive compared to epoxy grout, making it a cost-effective option for large-scale projects.
2. Ease of Application: It’s easier to work with because it has a longer setting time, allowing more time to adjust tiles.
3. Variety of Colours: Cement grout can be mixed with pigments to create a range of colours, enhancing the aesthetic appeal.

Cons of Cement-Based Grout

1. Porous Nature: Cement grout is porous, meaning it can absorb water and stains. This can lead to mould growth and discolouration over time, especially in areas exposed to moisture, like bathrooms and kitchens.
2. Prone to Cracking: Cement grout can shrink and crack as it dries, requiring regular maintenance and sealing to prevent damage.
3. Maintenance: To keep it looking fresh, cement grout needs to be regularly sealed and cleaned, particularly in high-moisture areas.

Epoxy Grout

Composition

Unlike cement-based grout, epoxy grout is made from a mixture of epoxy resins and a filler powder. This gives it a much stronger and more durable structure than traditional cement grout.

Pros of Epoxy Grout

1. Durability: Epoxy grout is extremely durable and resistant to cracking, making it a great long-term solution. It’s also resistant to water, stains, and harsh cleaning chemicals.
2. Waterproof: Since it’s non-porous, epoxy grout is perfect for wet areas such as showers, kitchens, and outdoor spaces. It won’t absorb water, meaning less chance of mould and mildew.
3. Stain-Resistant: Spills and stains are much easier to clean from epoxy grout as it doesn’t absorb liquids. This makes it ideal for areas prone to staining, like countertops and kitchen splashbacks.
4. No Sealing Required: Unlike cement-based grout, epoxy grout doesn’t need to be sealed, saving you time and effort in maintenance.

Cons of Epoxy Grout

1. Higher Cost: Epoxy grout is significantly more expensive than cement grout. It can cost up to three to five times more than traditional grout.
2. Difficult to Apply: Epoxy grout sets much faster than cement grout, meaning there’s less working time during application. It also requires more precision and care, making it more difficult to apply, especially for beginners.
3. Appearance: Some homeowners dislike the glossy, plastic-like finish of epoxy grout. It can look different from the traditional matte finish that cement grout provides.

Where to Use Cement Grout vs Epoxy Grout

At Plus Plumbing, we recommend cement grout for most indoor spaces, especially where the tiles won’t be frequently exposed to moisture. This includes areas like living rooms, bedrooms, and hallways. Cement grout can also be used in bathrooms and kitchens, but it requires regular sealing and maintenance to prevent water damage and stains.

On the other hand, epoxy grout is ideal for wet and high-traffic areas. It’s particularly useful for:

• Showers and bathrooms: Epoxy grout’s water-resistant properties make it perfect for areas where moisture is prevalent.
• Kitchens: The stain-resistant nature of epoxy grout ensures that spills won’t permanently damage the grout.
• Outdoor spaces: Because it’s resistant to weather changes and moisture, epoxy grout is a great choice for patios, walkways, and pool surrounds.

Inside Plus Plumbing

Recently, we were called out to a home in Lane Cove where a client was struggling with their bathroom’s grout. They had their bathroom renovated and the builder used normal cement grout, and within 2 years, it had started to crack and deteriorate. We stepped in with our expertise in epoxy grout, which is far more durable and resistant to moisture. After delicately grinding and removing the old grout and injecting the epoxy grout, the bathroom looked brand new.

As licensed plumbers, we also conducted in-depth pressure and dye leak tests to ensure everything was watertight. To top it off, we gave her a free set of shower taps with our service as part of a monthly promotion. Plus, with our 7-year warranty, the client now has peace of mind that their bathroom will stay in top condition, something other companies don’t offer.

Key Differences Between Epoxy and Cement Grout

1. Durability: Epoxy grout is much stronger and more durable than cement grout. It’s resistant to cracks, stains, and water, whereas cement grout is prone to these issues unless it’s properly sealed and maintained.
2. Cost: Cement grout is far more affordable than epoxy grout, making it a better option for those on a budget. However, epoxy grout’s durability may offer better value in the long run for high-use areas.
3. Ease of Application: Cement grout is easier to work with due to its longer setting time. Epoxy grout sets quickly, which can make it tricky for those without experience.
4. Maintenance: Cement grout requires regular sealing and cleaning, while epoxy grout is virtually maintenance-free once applied.
5. Appearance: Cement grout offers a wider variety of finishes and colours, while epoxy grout has a more uniform, plastic-like appearance.

Common Myths About Epoxy Grout

1. Epoxy Grout is Too Difficult to Work With: While epoxy grout can be tricky for beginners, experienced professionals like those at Plus Plumbing are well-equipped to handle the application process. As long as you hire a skilled tiler, epoxy grout is an excellent choice.
2. Epoxy Grout is Only for Commercial Use: While epoxy grout is popular in commercial settings, its durability makes it suitable for residential use as well, especially in bathrooms and kitchens where durability and water resistance are paramount.

Conclusion

Both epoxy grout and cement-based grout have their place in tiling projects. Cement grout is affordable, versatile, and easier to apply, but it requires more maintenance over time. Epoxy grout, while more expensive and harder to work with, offers unmatched durability, water resistance, and low maintenance.

At Plus Plumbing, we recommend assessing your specific needs—whether it’s a budget-friendly option for dry areas or a durable, water-resistant solution for high-moisture zones. For any tiling project, whether residential or commercial, it’s always best to consult with professionals to ensure the best materials are used.
