Discolored Grout No Longer Needs a Full Regrout
Refresh discolored cement grout without scraping or regrouting — waterproof once fully dry, 0.12 in acrylic tip, water-based formula with no added solvents
Why Is This Grout Refresh Perfect for You?
✔ Refresh grout without regrouting: Touch up discolored cement grout by drawing along a clean, dry grout line. Two coats help create an even finish, without scraping out the old grout or regrouting.
✔ Waterproof once fully dry: After the color has dried completely, the finish withstands shower water and steam. Allow it to dry fully before exposing it to water.
✔ Precise, low-odor application: The 0.12 in tip fits standard tile grout lines, and excess on tile can be wiped away with a damp cloth. The water-based formula has no added solvents and is low odor. For cement grout only; it covers mold but does not remove it.
