01Assess the Damage

  • The first step in fixing cracked grout is to assess the extent of the damage. Take a close look at the cracked grout lines and determine if the cracks are hairline or larger.
  • If the cracks are hairline and shallow, you may be able to repair them with a simple grout touch-up. However, if the cracks are large or deep, it may be necessary to remove the damaged grout and reapply new grout.
  • Additionally, inspect the surrounding tiles for any signs of damage or movement. If the tiles are loose or cracked, they should be addressed before fixing the grout.
  • Once you have assessed the damage, you can proceed with the appropriate repair method.

02Prepare the Area

  • Before starting any grout repair work, it is important to prepare the area to ensure a successful and long-lasting repair.
  • Start by cleaning the tiled surface thoroughly. Use a mild detergent and warm water to remove any dirt, grime, or grease that may be present. Scrub the surface gently with a soft brush or sponge.
  • Allow the surface to dry completely before moving on to the next step.
  • If you are planning to remove and replace the grout, use a grout removal tool or a small chisel to carefully scrape out the damaged grout. Be careful not to damage the surrounding tiles.
  • Once the grout has been removed, use a vacuum or a damp cloth to clean up any loose debris.
  • If you are planning to perform a grout touch-up, make sure the cracked grout lines are clean and dry. Remove any loose or crumbling grout with a utility knife or a grout saw.

03Repair the Cracked Grout

  • The repair method will depend on the extent of the damage and whether you are performing a grout touch-up or a full grout replacement.
  • For small hairline cracks, you can use a grout pen or a grout stain to color the cracks and make them less noticeable. Simply apply the grout pen or stain along the cracked grout lines, following the manufacturer's instructions.
  • If you are doing a full grout replacement, mix the grout according to the manufacturer's instructions. Using a grout float or a putty knife, spread the new grout over the cracked grout lines, making sure to fill them completely. Wipe off any excess grout with a damp sponge.
  • Allow the grout to dry for the recommended amount of time, usually 24 to 48 hours, before using the tiled surface.
  • Once the grout is dry, apply a grout sealer to protect the grout from stains and moisture. Follow the manufacturer's instructions for application.
  • If you are unsure about the repair method or feel uncomfortable doing it yourself, it is recommended to consult a professional.
