Quick Answer

For stone fabrication, use wet resin-bond diamond pads on granite and marble: start 50–100 for edge profiling, step to 200–400, then 800–1500–3000 for a mirror edge. Choose 4-inch pads for edges and 5-inch for tops, and always work wet to prevent heat fractures.

Key Features of Fabrication Pads

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

How to Choose by Stone and Step

Stone	Profiling	Polish	Gloss
Granite	50–100	200–800	1500–3000
Marble	50–100 (lighter touch)	200–400	800–1500
Quartz (engineered)	50–100	200–800	1500–3000

How to Use It

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

Frequently Asked Questions

Q: Which grit gives a mirror edge on granite?

A: Granite mirrors at 1500–3000 with wet resin pads; 3000 produces the deepest reflection.

Q: Can I use concrete polishing pads on stone?

A: Some overlap, but stone pads are formulated for wet, dense application — use dedicated fabrication pads for best results.

Q: Do fabricators use 3-inch or 4-inch pads for edges?

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

Conclusion

Match the pad line to the stone and always work wet. Profile with coarse grit, step through resin, and finish at 3000 for a mirror edge. Start with white resin polishing pads for consistent fabrication results.
