What is the primary purpose of grout in tiling?

To enhance color
To fill gaps between tiles and provide structural support
To waterproof the installation
To improve slip resistance

The correct answer is: To fill gaps between tiles and provide structural support

The primary purpose of grout in tiling is to fill the gaps between tiles and provide structural support. Grout serves as a bonding agent that helps hold the tiles together, ensuring that they remain stable over time. By filling the spaces, grout prevents dirt, debris, and moisture from accumulating between the tiles, which can lead to damage and mold growth. In addition to its structural roles, grout can also help distribute weight evenly across the tiled surface, minimizing the risk of cracking or displacement of the tiles themselves. This is particularly important in high-traffic areas or in installations that may experience movement, such as floors. While other factors such as color enhancement, waterproofing, and slip resistance may be considerations in certain applications of grout, they are secondary to its fundamental role in providing structural integrity to the tiled installation.
