What is the difference in sanded and unsanded grout?
Grouting is an essential step in tile installation, as it fills the spaces between tiles, providing both aesthetic appeal and structural integrity. When it comes to choosing the right grout, one often encounters two types: sanded and unsanded. Understanding the differences between these two types can help homeowners and contractors make informed decisions for their projects.
Sanded Grout:
Sanded grout is a popular choice for tile installations, especially for larger tiles and outdoor projects. It contains fine sand particles, which add body and durability to the grout. The presence of sand increases the strength of the grout, making it more resistant to cracking and movement due to thermal expansion and contraction. Sanded grout is also less likely to shrink or crack over time, ensuring a longer-lasting finish.
Unsanded Grout:
Unsanded grout, on the other hand, does not contain sand particles. It is typically used for smaller tiles, such as mosaic tiles, or in areas where the tiles are very close together, like in shower stalls or kitchen backsplashes. The absence of sand makes unsanded grout more pliable, which can be advantageous in tight spaces or when a finer finish is desired. However, it is important to note that unsanded grout is not as durable as sanded grout and may not be suitable for heavy traffic areas or outdoor applications.
Choosing the Right Grout:
When selecting between sanded and unsanded grout, consider the following factors:
1. Tile Size: For larger tiles, sanded grout is generally the better choice due to its increased strength and durability. Smaller tiles or mosaic tiles can be grouted with unsanded grout for a more subtle finish.
2. Installation Location: Outdoor or heavy traffic areas require sanded grout to withstand the elements and wear and tear. Unsanded grout is more suitable for indoor installations, such as shower stalls or kitchen backsplashes.
3. Desired Finish: If a fine, seamless look is preferred, unsanded grout may be the way to go. However, for a more pronounced texture and a rustic appearance, sanded grout can be used.
4. Color and Stain Resistance: Both sanded and unsanded grout come in a wide range of colors and finishes. Choose the type of grout based on the color and stain resistance that best suits your project.
In conclusion, the main difference between sanded and unsanded grout lies in their composition, durability, and suitability for various tile installations. By considering the factors mentioned above, you can make an informed decision that will ensure a long-lasting, attractive finish for your tile project.
