Grouting tiles is the process of filling the gaps between tiles with a thin, cement-based mixture called grout. Grout serves several purposes, including protecting the edges of tiles from damage, preventing water from seeping between tiles, and enhancing the overall appearance of the tiled surface. Here is a step-by-step guide on how to grout tiles:

  1. Prepare the tiles: Before you start grouting, make sure that the tiles are clean and free of any debris. Use a damp cloth to wipe down the tiles, and let them dry completely.

  2. Mix the grout: Follow the manufacturer's instructions to mix the grout. Typically, you will need to mix the grout powder with water in a bucket until it reaches a smooth and creamy consistency.

  3. Apply the grout: Using a rubber float or a grout trowel, apply the grout to the joints between the tiles in a diagonal pattern. Make sure to push the grout firmly into the joints to ensure that they are completely filled.

  4. Wipe off excess grout: Once you have applied the grout to all of the joints, use a damp sponge to wipe off any excess grout from the surface of the tiles. Rinse the sponge frequently to avoid spreading grout across the tiles.

  5. Allow the grout to set: Let the grout set for at least 20-30 minutes, or according to the manufacturer's instructions. During this time, do not walk on the tiled surface or allow water to come into contact with the grout.

  6. Remove any haze: After the grout has set, use a clean, dry cloth to remove any haze or residue from the surface of the tiles.

  7. Seal the grout: Once the grout is completely dry, you may want to consider sealing it to protect it from stains and moisture. Use a grout sealer according to the manufacturer's instructions.

By following these steps, you can successfully grout tiles and create a durable and attractive tiled surface. Keep in mind that grouting can be a time-consuming and labor-intensive process, so it is important to be patient and thorough to ensure the best results.
