After removing the tile leveler, you need to do two things

After removing the tile leveler, you need to do two things: ‌clean up the residue‌ and ‌check the flatness‌.

1. ‌Clean up the residue‌: Use a soft brush or vacuum cleaner to carefully clean the tile joints and surface, ensuring no plastic or metal debris remains. If there is stubborn adhesive in the joints, you can use a dedicated hook knife to clean it carefully, but be careful not to scratch the tile edges.

2. ‌Check the flatness‌: Use a spirit level to carefully check if the tile surface is completely flat and if the joint width is uniform. If any unevenness is found, you may need to readjust using the leveler again.

Once these two steps are completed, you can proceed to the next step of grouting.
