Choose a Grout Color

Standard grout comes in a variety of colors. 

  • Pick one that complements the color of your tiles. 
  • For a strong and colorfast grout, get the right consistency by using as little water as possible. 
  • Mix thoroughly to help minimize color variation. 
  • Only make as much as you can use before it begins to set.

Tip: Darker grout is a better choice for high-traffic areas.

Apply the Grout

  • Pour a quart to half gallon of grout on the tiles. 
  • Use a hard-edged rubber grout float, and hold it 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. 
  • Use this method for both pre-mixed and powdered grout.

Wipe the 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.
  • Be careful not to drag out any of the grout from the corners of the tiles.
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.
Apply the Sealer

  • Let the grout dry for the length of time recommended by the manufacturer before applying sealer. 
  • Spread the sealer with a small paintbrush or a sealer applicator. 
  • Clean off any smears within the first five minutes. 
  • Let the grout dry for at least 24-hours.
Caulk Along Baseboards and Walls

  • Caulk acts as both a sealer and as an expansion joint: 
  • It will flex if the floor expands or contracts as the weather changes. In wet areas, fill the gap with caulk and smooth with a wet finger.
  • This includes in front of a bathtub or shower, or wherever the expansion gap will not be covered with shoe moulding.
