Glass and mosaic tile are beautiful and unforgiving — the wrong blade shatters them. Here's how pros cut glass and mosaic tile cleanly.
The right cutting tools
- Glass-rated continuous-rim wet-saw blade — a fine, continuous diamond rim run wet is the cleanest way to cut glass; standard tile blades chip it.
- Wheeled mosaic nippers — score-and-snap small mosaic pieces and glass with carbide wheels.
- Tile nippers — for nibbling curves and small adjustments.
- Diamond hole saws — wet, for holes (see how to cut holes in tile).
Technique that prevents chipping
Go slow, keep it wet, and let the blade do the work — forcing glass cracks it. Apply painter's tape over the cut line to reduce surface chipping, and feed the tile steadily without twisting. For mesh-backed mosaics, cut between tiles where possible rather than through them.
Edges and finishing
Cut glass edges can be sharp — ease them with a diamond hand pad or rubbing stone for a safe, finished look, especially on exposed edges.
Set it right, too
Glass is transparent, so use a white thinset and full, void-free coverage — shadows and trowel lines show through. A smaller notch and back-buttering help.
