Sanded vs. Unsanded Grout: A Comprehensive Guide

When it comes to grouting tiles, the choice between sanded and unsanded grout can significantly impact the durability and appearance of your project. Understanding the differences and knowing when to use each type is crucial for achieving the best results. Let’s delve into the details to help you make an informed decision.

What is Grout?

Grout is a type of cementitious material used to fill the spaces between tiles. It provides stability, prevents water from seeping through, and enhances the overall aesthetic of the tiled surface. Grout comes in various colors and finishes, allowing you to customize the look of your tiles.

Sanded Grout

Sanded grout is designed for larger tile joints, typically 1/8 inch or more. The presence of sand in the mixture makes it more durable and less prone to cracking. Here are some key points to consider when using sanded grout:

• Increased Durability: The sand particles in sanded grout provide added strength, making it suitable for heavy-duty applications such as floors and showers.

• Reduced Cracking: Sanded grout is less likely to crack under pressure, ensuring a longer-lasting finish.

• Improved Adhesion: The sand particles help the grout adhere better to the tiles, reducing the risk of separation.

• Available in a Variety of Colors: Sanded grout comes in a wide range of colors, allowing you to match or complement your tile choice.

Unsanded Grout

Unsanded grout is ideal for smaller tile joints, typically 1/16 inch or less. It lacks sand particles, making it more flexible and easier to work with. Here are some advantages of using unsanded grout:

• Increased Flexibility: The absence of sand particles allows unsanded grout to bend and move more easily, reducing the risk of cracking in areas with movement, such as walls or countertops.

• Smooth Finish: Unsanded grout provides a seamless, smooth finish that can enhance the appearance of tiles, especially in smaller joints.

• Reduced Weight: Unsanded grout is lighter than sanded grout, making it easier to apply and less likely to cause tiles to crack under pressure.

• Available in a Variety of Colors: Similar to sanded grout, unsanded grout comes in a wide range of colors to match your tile selection.
