  2. Remove the damaged grout using a grout saw or scraper.
  3. Clean the joints and allow them to dry completely.
  4. Apply new grout with a grout float, pressing it firmly into the joints.
  5. Wipe away excess grout with a sponge and let it dry.
  6. Once dry, apply a waterproof sealant to the grout lines and corners.
