<human>:  How do I repair a loose tile on the floor?
<bot>: First, you will need to remove the loose tile. Carefully use a pry bar or flathead screwdriver to dislodge the tile. Next, clean the area in preparation for a new tile. Use a broom, vacuum, and mild cleaner to get the area free of debris. You may also need to scrape away leftover adhesive, if any. Finally, install the new tile. Apply adhesive in sections to ensure sufficient coverage, and use a level to get the tile straight. Let the adhesive set for the manufacturer’s determined time before walking on the new tile.
