The best wall grout depends on where the tile is installed, how much moisture it will be exposed to, and the level of durability required. For most wall applications, professionals choose between cement grout, epoxy grout, and single-component grout, with modern options like ARDEX offering strong performance with easier installation and cleanup.

If you are installing tile on walls, choosing the right grout is just as important as selecting the tile itself. The wrong grout can lead to staining, cracking, or difficult maintenance. The right grout will improve durability, enhance appearance, and make long-term maintenance easier.

What Is Wall Grout?

Wall grout is the material used to fill the joints between tiles on vertical surfaces such as:

• Shower walls
• Kitchen backsplashes
• Bathroom walls
• Feature walls and accent tile

Unlike floor grout, wall grout does not need to handle heavy foot traffic. However, it still needs to resist moisture, staining, and cracking while maintaining a clean, finished look.

Types of Wall Grout (And When to Use Them)

Understanding the different types of grout is key to choosing the best option for your project.

Cement Grout

Cement grout is the traditional option used in many tile installations.

Best for:

• Backsplashes
• Low-moisture wall areas
• Budget-friendly projects

Pros:

• Easy to work with
  
• Widely available
• Cost-effective

Cons:

• Requires sealing
• More prone to staining
• Can crack over time

Cement grout is still used, but many installers are moving toward newer options for better performance.

Epoxy Grout

Epoxy grout is a high-performance option known for its durability and resistance.

Best for:

• Showers
• Wet areas
• High-use installations

Pros:

• Waterproof
• Stain-resistant
• Extremely durable

Cons:

• More difficult to install
• More expensive
• Faster working time

Epoxy grout is often considered one of the best choices for demanding environments, especially showers.

Single-Component Grout (Modern Solution)

Single-component grout combines the best features of cement and epoxy grout while being easier to use.

Best for:

• Showers
• Backsplashes
• Residential and commercial wall tile

Pros:

• Ready to use
• No mixing required
• Stain-resistant
• Flexible and crack-resistant
• Easier cleanup than epoxy

One of the most popular options in this category is available from ARDEX.
