Tile grouting is the process of filling the gaps between tiles with a cement-based mixture, which helps to hold the tiles in place and provide a clean, finished look. It is an essential step in tiling, as it helps to prevent moisture and dirt from getting between the tiles and damaging the surface beneath them.
Grouting can also enhance the overall appearance of the tiled area, as it can be customized with different colors and finishes to match the tiles or create a contrasting effect. Proper preparation and application are important to ensure a durable and long-lasting grout job.
