Tile grouts are materials used to fill the spaces between tiles, providing both aesthetic appeal and structural support. They help to prevent moisture from seeping beneath the tiles, which can lead to mold and damage. Grouts come in various types, including cement-based, epoxy, and urethane, each offering different levels of durability and flexibility. In addition to their functional role, tile grouts can enhance the overall look of a tiled surface. They are available in a wide range of colors, allowing homeowners and designers to create contrasting or complementary effects with the tiles. Properly applied grout can significantly extend the lifespan of a tile installation.
