Step-by-Step Guide on How to Fix Mosaic Tiles in Swimming Pool

1. **Assess the Damage**: Begin by identifying which tiles are damaged. If you find any loose tiles, carefully check for cracks or breaks underneath.

2. **Remove Damaged Tiles**: Use a chisel and hammer to gently remove broken tiles. Be cautious not to damage adjacent tiles.

3. **Clean the Area**: Once the damaged tiles are removed, clean the surface thoroughly to ensure proper adhesion. Remove any old adhesive and debris.

4. **Apply Adhesive**: Use a trowel to spread tile adhesive or thin-set mortar onto the surface where the new tiles will be placed. Ensure the adhesive is evenly distributed.

8. **Clean Excess Grout**: Use a damp sponge to gently wipe away excess grout from the tiles. Be careful not to displace the grout from the joints.

9. **Cure the Grout**: Let the grout cure fully as per the manufacturer’s guidelines, typically 48-72 hours.
