How to Repair the Grout on Ceramic Tile


Ceramic tile can be a beautiful covering for a floor or wall. But the grout between tiles can get dirty or chipped, making it look dingy and ugly. Repairing ceramic tile grout can make a surface look new without having to pay for an entirely new tile floor.

Things You'll Need

  • Grout removal tool
  • Rubber float
  • Bucket
  • Sponge
  • Identify areas where grout has chipped and scrape it out with a hand-held grout removal tool. You can find one for less than $5 at home centers. The tool has teeth or a carbide blade you can use to scrape out damaged grout. Make sure all the grout is removed, and the joint is free of dust.

  • Clean the joint with clean water. Moisture can help the new grout stick, but avoid leaving any standing water.

  • Choose a grout color that matches the nearby existing grout. Premixed grout often comes in white and various shades of gray.

  • Scoop grout onto the joint. Use a rubber grout float to drag the grout into the joint. Move the float at a 45-degree angle to the joints to pack it in.

  • Remove the excess grout with a wet sponge once it sets and hardens. Later, after the tile dries, remove a haze that will remain with a dry towel.

Tips & Warnings

  • Use knee pads when working on a tile floor. Your knees could hurt after working for a while.
  • Read the safety instructions on the grout.
