When planning a tile installation, choosing the right grout is just as important as selecting your tiles. Grout not only fills the spaces between tiles but also plays a vital role in the longevity, appearance, and durability of the tiled surface.

One of the most common questions DIYers and professionals alike ask is:

What’s the difference between sanded and unsanded grout—and when should I use each?

In this guide, we’ll break down the key differences, explore their best-use cases, and highlight top LATICRETE® grout products in each category to help you make the right choice for your next tile project.

What is the Difference Between Sanded and Unsanded Grout?

When to Use Sanded Grout

Sanded grout is ideal for:

• Floor tile installations

• Wider grout joints (1/8" to 1/2")

• Areas that experience heavy foot traffic

How to Choose the Right LATICRETE® Grout

Ask yourself these key questions:

1. What is the width of your grout joints?

   • < 1/8": Go with unsanded

   • ≥ 1/8": Choose sanded

2. What kind of tiles are you using?

   • Delicate, glass, or polished stone? ➜ Unsanded

   • Porcelain, ceramic, or textured stone? ➜ Sanded

3. Where is the tile being installed?

   • Wet or submerged areas? ➜ Consider SPECTRALOCK® epoxy grout

   • Walls? ➜ Unsanded is easier to apply vertically

   • Floors or high-traffic zones? ➜ Sanded or epoxy for durability
