How to Grout Tile

Grouting is the process of filling the spaces in between tiles. Most options come in powder form, but premixed containers are available as well. Whichever option you choose, follow the manufacturer’s instructions on how to mix grout. Keep any leftover dry mix for future repairs, but make sure to store it in moisture-free areas.

This guide details how to apply tile grouting, how use the float and sponge and how to apply sealant and caulk.

1. Mixing Grout

Pour water into the container, pour the powder while stirring with a stirrer, stir for 3-5 minutes (water and powder 1:4 ratio), let it stand for 10 minutes, stir again and use.

2. Applying Grout

Holding a hard-edged rubber grout float at a 45-degree angle, spread the material in sweeping arcs, pressing it into the joints to fill them completely. Work in a small area at a time, roughly a 3 x 3-foot section. Stir frequently during construction for maximum maneuverability.

3. Wipe Tile With a Damp Sponge

Wait a few minutes while the grout begins to harden. Wipe the tiles in a circular motion with a damp sponge, taking care not to drag out any of the grout from the corners of the tiles.

4. Use a Damp Cloth to Remove the Haze

Once the grout has hardened, the tiles will be left with a slight haze on them. Clean it up by going over the area lightly with a damp cloth, then buff immediately with a dry cloth.

5. Let Grout Dry 

After 24 hours of caulking, it is recommended to use watering for curing to improve product strength.
