What does the term "grout" refer to in tile installations?

Grout refers specifically to the material used to fill the spaces between tiles after they have been installed. This filling serves several important purposes in tile installations. Firstly, it helps to secure the tiles in place and prevents them from shifting over time. Secondly, grout acts as a barrier against moisture, which is essential in areas prone to water exposure, such as kitchens and bathrooms. Additionally, it contributes to the aesthetic appearance of the tiled surface, as it can come in a variety of colors to either contrast with or complement the tiles.

Understanding the function of grout is critical for maintaining the integrity and look of tile flooring or wall applications. Knowledge of grout helps ensure that tile installers select the appropriate type for the specific installation requirements, including considerations for water resistance, color matching, and overall durability.
