Support the tile while cutting so it does not break at the corner.
Use the correct blade/tool for the tile type.
Make corners clean — no wild overcuts.
Vacuum/wipe dust and reinstall the tile without dirty fingerprints.
Ask foreman
Do you want me cutting these tiles now, or are we waiting for final ceiling/layout approval before finish install?
Do not
Stop if the tile location is not verified, the device/frame type is unknown, or the area is protected/finished and you do not have dust-control direction.
Why it matters
Finish work is where rough-in becomes visible, inspected, balanced, serviced, and turned over. Clean install and access matter.
