Regrouting over old grout is a practical solution for revitalizing tiled surfaces without a full renovation. This process, however, depends on the condition of the existing grout and the method used. In this guide, we’ll explore when and how regrouting is feasible, tips for ensuring success, and why grout cleaner is crucial for the task.

- Moisture Exposure: Prolonged water contact erodes grout.
- Wear and Tear: Daily use and cleaning weaken grout lines.
- Improper Installation: Poor techniques lead to early damage.
