Find the Right Granite Polishing Pad for Your Job
| Best for | Recommended Pad | Bond | Machine / RPM | Finish |
|---|---|---|---|---|
| Granite countertop edge polishing (wet) | 4" Wet Pads – Granite & Marble Edge | Resin | Wet polisher, 2,000–3,000 RPM | Mirror |
| Granite sink cutouts & tight radius | 2" Wet Pads – Sink Cutouts | Resin | Wet polisher, 2,000–3,000 RPM | Gloss |
| Granite edge work on-site, no water | 3" & 4" Dry Pads – Jobsite | Resin | Angle grinder, 1,500–2,500 RPM | Satin–gloss |
| Heavy lippage / leveling | 4" Metal Bond Grinding Pads | Metal | Grinder, 1,500–2,000 RPM | Flat / level |
3-Step vs 7-Step for Granite
Use a 3-step system for maintenance, light wear, and production shops that need speed: fewer grits, less time per top, consistent satin-to-gloss finish. Use a 7-step system for new countertops, deep scratches, dark granite, and visible surfaces where a mirror finish matters. The 7-step sequence removes the previous grit's scratch pattern more gradually, so the final gloss is more uniform. If the surface is flat and only lightly dull, 3-step is enough; if you can see scratches at an angle, start coarser and finish with 7-step.
RPM & Pressure
Run wet resin pads at 2,000–3,000 RPM (the 94 GU test used 2,800 RPM). Dry pads: 1,500–2,500 RPM. Use light, even pressure — let the diamonds cut, don't bear down. Keep the pad moving, overlap passes by 50%, and maintain water flow around 2.5 L/min for wet work. If the pad grabs or the stone heats up, reduce RPM and speed up the passes.
94 GU Mirror Gloss Test
On a black granite slab, KAIYI 4" wet pads (Model 34) reached 94.02 GU average after S0–S4 at 2,800 RPM with continuous water. Measurement: 3nh 60° gloss meter, ISO 2813 / ASTM D523, 5-point grid; all five points read 94.0 GU, above our ≥85 GU acceptance threshold. Results vary by stone, operator, and machine — use this as a reference, not a guarantee.

Frequently Asked Questions
What are the best diamond polishing pads for granite?
For granite countertop edges, 4" wet diamond polishing pads with a 7-step grit sequence (50–3000) deliver the best mirror finish. KAIYI pads use high-temperature resin bond calibrated for hard natural stone, preventing heat damage at professional polishing speeds.
What grit sequence should I use for granite countertop polishing?
Start with 50 or 100 grit for stock removal and scratch elimination, progress through 200–400 grit for surface refinement, then finish with 800–1500–3000 grit for a mirror gloss. A 3-step system covers fast results; a 7-step system delivers the highest-quality finish on granite.
What is the MOQ for granite polishing pads?
Standard stock MOQ is 100 pcs per grit. Samples on request — sample fee credited on your first order. Custom OEM starts at 500–1,000 pcs.
3-step or 7-step for granite?
Use a 3-step system for maintenance, light wear, and production shops that need speed: fewer grits, less time per top, consistent satin-to-gloss finish. Use a 7-step system for new countertops, deep scratches, dark granite, and visible surfaces where a mirror finish matters.
What RPM and pressure should I use?
Run wet resin pads at 2,000–3,000 RPM (2,800 RPM recommended); dry pads at 1,500–2,500 RPM. Apply light, consistent pressure, overlap passes by 50%, and maintain continuous water flow (~2.5 L/min) for wet polishing.
Can these pads reach 90+ GU?
In our standardized test on black granite, KAIYI 4" wet pads reached a 94.02 GU average across a 5-point grid under ISO 2813 / ASTM D523. Results vary by stone hardness and operator technique, but reliably exceed the industry ≥85 GU threshold.
