Step 1: Mix the Grout

Mix the grout per the manufacturer's instructions, and be sure to pick a color that complements your tile selection. Go by the grout chart at the retail store. Mix the grout with clean, cold water to the consistency of a milkshake.

Step 2: Apply the Grout

After moistening the tiles with a nearly dry sponge, apply the grout with a laminated grout float. Push the grout into the joints with the flat edge of the float. Push the grout over the face of the tiles diagonally with the flat edge of the float to cut off the excess grout.

Step 3: Let the Grout Set

Work in small manageable areas, and continue the process over the entire area until all joints have been grouted. Allow the grout to set and haze over. With a nearly dry sponge, tool the grout to eliminate pinholes, voids, highs and low spots.

Note: Grout should set for 24 hours.

Step 4: Remove any Residue

Do a final wipe with a nearly dry sponge pulled diagonally over the face of the tile to remove any grout residue.

Step 5: Seal the Grout

After the grout has cured for a minimum of 48 hours, or whatever the manufacturer recommends, seal the grout with a sealer.
