Answer
For tile edges, wet sand lightly with 220 or 320, then refine with 400 or 600.
Why it happens
Fresh tile cuts leave small chips and sharp edges that need controlled smoothing.
Recommended grit
Use 220 or 320 for rough edges, then 400 or 600 for smoother edge finishing.
Wet or dry
Wet is preferred to control dust and improve finish.
Success check
The edge feels smooth without visible new chips.
What to do
- Rinse or wipe the tile edge clean.
- Sand the sharp edge lightly with 220 or 320.
- Refine with 400 or 600.
- Wipe the edge and check by touch.
Avoid: Do not press hard enough to chip the glaze.
