Quick Answer

The gloss comes from the sequence, not from any single pad. For stone fabrication, use wet resin-bond diamond pads on granite and marble: start 50–100 for edge profiling, stage to 200–400, then 800–1500–3000 for a mirror edge. Select 4-inch pads for edges and 5-inch for tops, and always work wet to prevent heat fractures.

Key Features of Fabrication Pads

The practical details.

• Grit stage set: 50–3000 covers profiling to mirror finish.
• Backing: hook-and-loop or fixed; match to your hand grinder backing plate.
• Wet application: water cools the stone and flushes swarf, preventing burns.
• Resin-bonded matrix: flexible resin pads follow edge profiles and radius work.

Crews that rush this part rarely get a mirror finish.

A Practical Guide to Choose by Stone and Step

Key points for the polishing sequence.

This stage decides how much reflection the floor finally shows.

Use It: Step-by-Step

What matters most in this stage.

• Finish edges with 1500–3000 on a small pad holder for a mirror edge.
• Stage through white resin burnish pads to strip router marks.
• Profile the edge with a router or hand pad at 50–100 grit stage, wet.
• Keep the stone wet throughout; dry pads burn granite and dull marble.

Miss this step and the gloss will not come up evenly.

Frequently Asked Questions

Q: Which grit gives a mirror edge on granite?

A: The practical answer is, Granite mirrors at 1500–3000 with wet resin pads; 3000 produces the deepest reflection.

Q: Is it possible to use concrete polishing pads on stone?

A: For most jobs, Some overlap, but stone pads are formulated for wet, dense application — use dedicated fabrication pads for most suitable outcomes.

Q: Is it necessary to fabricators use 3-inch or 4-inch pads for edges?

A: In short, 4-inch is the standard for most edges; 3-inch fits tighter radius work and sinks.

Conclusion

The finish is the sum of the stages - stay disciplined and the floor shines. Profile with coarse grit stage, stage through resin, and finish at 3000 for a mirror edge.
