Grouting is a construction process that involves filling the gaps or spaces between tiles, bricks, or stones with a thick paste called grout. This paste is typically made from a mixture of water, cement, and sometimes sand. Grouting helps to secure the tiles in place, prevents moisture from seeping behind them, and enhances the overall appearance of the surface. There are different types of grout, including sanded grout and unsanded grout, each suited for specific applications. Sanded grout is used for wider joints, while unsanded grout is ideal for narrow spaces. Proper grouting is essential for the durability and longevity of tiled surfaces.
