Determine the grout color of your choice. For best results, choose on the color-coordinates with the tile.
Carefully read all instructions and precautions on the package. Mix grout according to instructions. Make only enough to use within about 30 minutes. Wear protective gloves to protect your skin. Spread the mixed grout on the tiled surface, forcing grout down into joints with a rubber grout float or squeegee. Tilt the float at a 45 degree angle to aid the compacting action. Remove excess grout from the surface immediately with edge of float. Tilt float at a 90 degree angle and scrape it diagonally across the tiles. Continue the process of compacting, then scraping off excess, until you have grouted for approximately 30 minutes or when the mixture begins to stiffen. Discard stiffened grout mixture and begin cleanup procedure.

Cleanup:
Wait 15 to 20 minutes for grout to set slightly, the use a damp sponge to clean grout residue from the surface and smooth the grout joints. Rinse sponge frequently and change water as needed. Let the area dry until grout becomes hard and a haze forms on the tile surface, then polish with a soft cloth. If haze is stubborn, you may want to rinse again with a sponge and clean water. Wait 72 hours before heavy use. Do not apply sealers or polishes for three weeks until fully-cured, and only in accordance with manufacturer's recommendations.
