Understanding the Distinction Between Grout and Sanded Grout

When it comes to tile installation, choosing the right grout is vital to ensure a secure and aesthetically pleasing outcome. This article aims to provide a comprehensive guide to understanding the differences between grout and sanded grout, their applications, and considerations.

What is Grout?

Grout is a powder that, when mixed with water, transforms into a creamy consistency and is used to fill the spaces between tiles or for stone wall and floor coverings. It provides a smooth finished product and is commonly used in areas where low stress is expected.

Types of Grout

Non-Sanded Grout

Non-sanded grout is specifically designed for grout joints that are narrower than 1/8 inch. This type of grout is ideal for wall installations or surfaces where minimal stress is applied. Non-sanded grout typically won't scratch tile surfaces, making it a safer choice for glaze and glass tiles. However, caution is advised when using it for decorative tiles as it may damage the finish surface if overused or applied aggressively during installation.

Sanded Grout

Sanded grout, on the other hand, is used for grout joints wider than 1/8 inch. This type of grout includes small aggregate which makes it much stronger and more resilient. It is particularly recommended for floor applications due to its ability to offer some slip resistance and prevent cracking due to shrinkage.

Application Considerations

When choosing between grout and sanded grout, several factors must be considered. For example, in floor applications, manufacturers often recommend using sanded grout because of its strength and ability to provide slip resistance. However, for wall installations, non-sanded grout is typically the preferred choice due to its flexibility and suitability for areas with minimal stress.

Mixing and Consistency

Proper mixing and consistency are crucial for achieving the best results. Grout should be mixed to a peanut butter-like consistency, neither too wet nor too dry. Adding excessive water or other additives can lead to staining and poor performance.

Manufacturers’ Warranties

Manufacturers typically warrant unsanded grout for 1/8 inch joints and sanded grout for larger joints, such as 1/4 inch. This warranty difference reflects the intended use and expected durability of each type of grout. It's important to select the appropriate grout type based on the size of the joints and the expected stress on the installation.

Common Uses and Applications

Both grout and sanded grout serve the same basic purpose of filling gaps between tiles, but they differ in their composition and intended use. Grout is best for applications where joints are narrow and low stress is expected, while sanded grout is ideal for broader joints and areas with greater stress, such as floors.

Conclusion

Choosing the right grout or sanded grout for your tile installation project is crucial for ensuring a durable and aesthetically pleasing outcome. By understanding the differences between these two types of grout and considering their applications, you can make an informed decision that satisfies both your aesthetic and functional needs.
