Grit Selection Guide:
- Grit 50 & 100: Coarse grinding, lippage removal, saw mark elimination.
- Grit 200 & 400: Honing, surface refinement, scratch removal.
- Grit 800 & 1500: Polishing, gloss development.
- Grit 3000: Mirror finish, final buffing stage.
Usage Tips
- Always maintain continuous water flow — never use wet pads dry.
- Inspect surface under raking light between each grit stage before advancing.
- Use 2,000–4,500 RPM depending on grit: lower for coarse, higher for fine finishing.
- Apply 10–20 lbs of downward pressure. Excessive pressure accelerates pad wear.
- Break in new pads on scrap stone for 30–60 seconds before use on finished surfaces.
Technical FAQ
Can I use these pads on concrete?
Yes. For concrete, follow up with a lithium silicate densifier after Grit 400, cure 24 hours, then continue to 800 and 3000 for a high-gloss finish.
Are these pads compatible with standard angle grinders?
Yes. The hook & loop (Velcro) backing is compatible with all standard 4-inch angle grinders with a flexible backing plate.

Frequently Asked Questions
How to use wet diamond polishing pads?
Connect your polisher to a water source. Set water flow to a light, continuous stream. Run at 3,000-4,500 RPM. Keep the pad moving. Progress from 50 grit through 3000 grit for mirror finish. Clean the surface between grit changes.
What pad do you use to polish concrete?
For concrete: metal bond diamond pads (30-100 grit) for aggressive grinding and lippage removal, then resin bond pads (200-3000 grit) for polishing. KAIYI offers both metal and resin bond concrete polishing pads. For countertops, start at 100 grit wet diamond pads.
How to diamond polishing pads for concrete?
Start with 50 grit for surface preparation. Progress through 100 → 200 → 400 → 800 → 1500 → 3000 grit. Apply concrete densifier after 400 grit. Use wet method for best results and dust control.
Are granite and concrete polishing pads different?
Yes. Concrete pads use a harder bond matrix for abrasive concrete surfaces. Granite pads use softer resin bonds for hard natural stone. Concrete polishing often requires metal bond pads for initial grinding stages.
How to use diamond polishing pads on stone?
Start with the coarsest grit and work through progressively finer grits (50 → 100 → 200 → 400 → 800 → 1500 → 3000). Keep the pad moving. Use light to moderate pressure. Wet method recommended for stone surfaces.
Should you wet polishing pads?
Yes — wet diamond polishing pads must be used with water for cooling, dust control, and finish quality. Dry pads are designed with honeycomb cooling and should not be used with water.
Can you use wet polishing pads dry?
No. Wet diamond polishing pads rely on water for cooling. Using them dry causes rapid heat buildup, pad delamination, and stone damage. Use KAIYI dry diamond polishing pads for water-free applications.
How to clean diamond polishing pads?
Rinse pads with clean water after each use. Use a soft brush to remove slurry. Air dry completely before storing. Replace when diamond layer is worn below 1mm.
