Sanded vs. Unsanded Grout: Choosing for DIY Tiling Projects
When it comes to tiling your home, grout plays a significant role in the finished look and long-term durability of the project. Whether you’re tackling a kitchen backsplash, bathroom floor, or mosaic accent wall, understanding the difference between sanded and unsanded grout is crucial. In this guide, we’ll explore when to use sanded vs. unsanded grout, highlight key differences, and help you choose the best grout for your DIY tiling projects.
Sanded vs. Unsanded Grout
What’s the Difference Between Sanded and Unsanded Grout?
At first glance, grout might seem like a one-size-fits-all material, but it comes in two main varieties: sanded and unsanded. Here’s the breakdown:
- Sanded grout contains fine sand particles, making it more durable for wider grout joints.
- Unsanded grout, on the other hand, is smooth and paste-like, perfect for narrow gaps and delicate tiles.
For example, the difference between sanded and unsanded grout for backsplash tiles often boils down to joint width and the type of tile used.
When to Use Sanded vs. Unsanded Grout in Shower Projects
If you’re working on a shower wall, you’ll need to consider both joint width and the tile material. Sanded grout works well for joints wider than 1/8 inch, but if you’re dealing with narrow tile gaps or glass tiles, unsanded grout is a better choice.
For example, subway tiles in a shower often benefit from unsanded grout, as it prevents scratching and fills tight spaces effectively.
Best Grout Type for Large Floor Tiles
When installing large-format tiles on a floor, durability is key. Sanded grout for large grout lines is ideal because the sand particles add strength, preventing cracking over time.
- Pro Tip: Use a grout calculator to estimate the amount you’ll need, especially for expansive areas like kitchen floors.
Mixing Sanded Grout for the First Time (DIY Tips)
If this is your first DIY tiling project, mixing sanded grout can seem intimidating. Here’s a quick guide:
- Start with clean water and slowly add grout powder while stirring.
- Aim for a peanut butter-like consistency.
- Let it rest for 10 minutes before re-stirring.
Can You Use Unsanded Grout on Floor Tiles?
In most cases, unsanded grout is not recommended for floor tiles because it lacks the strength to withstand heavy foot traffic. However, for small mosaic tiles or joints narrower than 1/8 inch, it can be an option.
Cost Comparison: Sanded vs. Unsanded Grout
If budget is a factor in your project, you’ll be happy to know that sanded grout is often less expensive than unsanded grout due to its simpler composition. That said, always prioritize choosing the right type of grout for your project over saving a few dollars.
Which Grout Should You Use for Bathroom Wall Tiles?
For bathroom walls, the choice often depends on the tile material and joint width:
- For ceramic or porcelain tiles with narrow joints, unsanded grout works best.
- For wider joints or textured tiles, sanded grout ensures a strong, durable finish.
Grout Calculator for Kitchen Backsplash Tiles
To avoid running out of grout mid-project, use a grout calculator. Simply input the tile dimensions, joint width, and area size to determine how much grout you’ll need. This is especially helpful for precise jobs like kitchen backsplashes.
