You’re finally ready to finish your gorgeous tile floor, but then you hit a snag: the grout. Unsanded grout is cheap and easy to use, while sanded grout seems more complex. But can you use unsanded grout on your floor? The answer isn’t as simple as a yes or no.

I recently renovated my kitchen and opted for a rustic, farmhouse look, choosing wide plank tile for the floor. I was so excited to get started but quickly realized I needed to do my research on grout. While I initially thought unsanded grout would be a breeze, after some digging, I realized it wasn’t the right choice for my project. Let’s dive into the world of grout and figure out whether unsanded grout is a good fit for your floor.
Understanding Grout
Grout is a cementitious paste that fills the gaps between tiles, offering a cohesive aesthetic and protecting the substrate from moisture and wear. The key ingredient is cement, which binds with water and creates a hardened mixture that resists water damage. Along with cement, other ingredients include fine sand, pigments for coloring, and sometimes polymers for added flexibility. There are two main types of grout, sanded and unsanded.
Unsanded grout, the more common type, is made from a fine paste of cement, water, and pigments. It is perfect for thin grout lines, ideal for creating a smooth, sleek finish, especially on tile surfaces with tight spaces. Its lack of sand makes it easy to apply and clean, requiring less effort for smoothing and wiping away excess material. Unsanded grout can be your best friend if you’re a DIY enthusiast or if you prefer a clean, minimal look. It’s typically chosen for walls, countertops, and even certain floors, depending on the tile size and the type of foot traffic.
Sanded grout, on the other hand, consists of cement, water, pigments, and the addition of fine sand. This sand allows the grout to remain stable, preventing it from shrinking over time, which makes it an excellent choice for larger grout lines and high-traffic areas where the grout is susceptible to stress and wear. The sand’s presence also strengthens the mixture, making it more durable and less prone to cracking. If you’re working with a floor with grout lines wider than 1/8 inch, sanded grout is the more reliable option to achieve long-lasting results.
The Role of Tile Size and Grout Line Width
One crucial factor in determining whether to use unsanded or sanded grout is the size of your tiles and the width of the resulting grout lines.
Smaller Tiles and Narrow Grout Lines
Unsanded grout is generally considered ideal for smaller tiles, particularly those with grout lines under 1/8 inch. In these cases, the sand in sanded grout could create a gritty texture that detracts from the overall aesthetic, especially if you’re looking for a smooth, minimalist finish. The finer consistency of unsanded grout blends seamlessly with smaller tiles, leading to a uniform and elegant appearance.

Larger Tiles and Wider Grout Lines
When working with larger tiles, like those found in many modern homes, the use of unsanded grout becomes riskier. Since the grout lines tend to be wider than 1/8 inch, unsanded grout can shrink over time, leading to unsightly cracks and gaps. The fine sand in sanded grout, along with its higher cement content, provides greater strength and stability, making it the better option to withstand the stress of wider grout lines. It’s crucial to consider the high-traffic areas where the tiles are placed, as movement and weight can exacerbate the shrinking issue with unsanded grout, leaving you with a less than perfect finish.
Foot Traffic and Environmental Considerations
The amount of foot traffic your floor receives also plays a big role in determining the type of grout. Unsanded grout is less durable than sanded grout and can deteriorate quickly in areas with heavy foot traffic, like kitchens and hallways. The absence of sand makes it more vulnerable to abrasion and scratching, which can lead to a dull and unappealing appearance over time. Sanded grout, however, is designed to withstand the rigors of heavy foot traffic, providing a more durable and long-lasting solution.
Environmental factors can also impact the longevity of grout. If your floor is exposed to moisture or constant temperature fluctuations, sanded grout’s superior strength and water resistance come into play. The sand in sanded grout acts as a barrier against moisture penetration, preventing deterioration and preserving the integrity of the grout lines. Unsanded grout, lacking this protective element, is more susceptible to moisture damage, leading to cracking, discoloration, and even mold growth if not properly sealed.
Tips and Expert Advice for Choosing the Right Grout
The choice between sanded and unsanded grout is often a delicate balance of aesthetics, practicality, and durability. Here is a summary of some vital considerations:
- Tile Size and Grout Line Width: For smaller tiles and narrow grout lines, use unsanded grout. However, for larger tiles and wider grout lines, use sanded grout.
- Foot Traffic: If your floor has high traffic, use sanded grout. Unsanded grout is less durable and may not hold up to heavy foot traffic.
- Environmental Factors: For high-moisture environments, such as kitchens and bathrooms, use sanded grout for enhanced protection against water damage.
- Aesthetic Appeal: Unsanded grout offers a smooth, seamless finish, perfect for modern minimalist designs. Sanded grout provides a sturdier finish but may have a slightly rougher appearance.
- Ease of Application: Unsanded grout is easier to apply and clean, which might be an advantage for DIY enthusiasts.
- Cost: Unsanded grout is often cheaper and easier to find than sanded grout.
In the end, choosing the right grout is determined by a combination of factors. Consider the tile size, grout line width, foot traffic, and moisture exposure. While unsanded grout can be tempting due to its ease of use and affordability, it is often not the best choice for floors, especially those with wider grout lines or high traffic. Sanded grout offers superior durability and protection against cracking and moisture damage, making it a more reliable option for most floors. But ultimately, research and careful consideration are essential to selecting the perfect grout for your project.
Frequently Asked Questions
Q: Can I use unsanded grout for floor tiles with thin grout lines?
A: It is generally safe to use unsanded grout for floor tiles with thin grout lines, especially if the foot traffic is minimal. However, remember that unsanded grout offers less durability and is more susceptible to cracking and discoloration, especially in high-traffic areas or in places exposed to moisture.
Q: What are the drawbacks of using unsanded grout on the floor?
A: Unsanded grout lacks the strength and durability of sanded grout, making it more vulnerable to cracking, shrinking, and discoloration. It also tends to be more sensitive to moisture and can deteriorate rapidly in high-traffic areas.
Q: What are some good alternatives to unsanded grout for floors?
A: If you want a smooth, seamless finish but need the strength and durability of sanded grout, consider using epoxy grout. Epoxy grout offers superior resistance to moisture, staining, and wear, making it a great choice for high-traffic areas and outdoor applications.
Q: How do I install unsanded grout if I decide to use it?
A: If you are using unsanded grout, it’s crucial to follow the manufacturer’s instructions carefully. Ensure you use a smooth trowel and work in small sections, avoiding overworking the grout. Allow the grout to dry completely and seal it after installation to protect it from moisture and staining.
Can I Use Unsanded Grout On Floor
Conclusion
Choosing the right grout for your floor tile project is an important decision that impacts both aesthetics and durability. While unsanded grout can be an appealing option for its ease of use and affordability, the lack of sand makes it less resistant to cracking, moisture, and wear. For floors, especially those with larger tiles or high-traffic areas, sanded grout generally offers a more reliable and long-lasting solution. Always research and consider your specific needs and circumstances before making your final decision.
