Technical FAQ
Can these dry pads be used with water?
These pads are optimized for dry use. For wet applications, see our dedicated wet polishing pad range.
Will dry polishing leave burn marks on marble?
Keep the pad moving at all times and avoid excessive pressure. The honeycomb geometry actively dissipates heat to protect delicate stone surfaces.

Frequently Asked Questions
What to use to polish stone surfaces?
Diamond polishing pads are the professional standard for stone fabrication. Use wet diamond pads (grit 50-3000) with a variable-speed polisher for granite, marble, and concrete. For on-site work, dry diamond pads with honeycomb cooling design require no water.
How to use diamond polishing pads?
Start with the coarsest grit (50 or 100) and work through progressively finer grits (200 → 400 → 800 → 1500 → 3000). Keep the pad moving at all times. Use light to moderate pressure — let the diamonds do the work. Run at 3,000-6,000 RPM depending on grit. Clean the surface between grit changes.
Where to buy diamond polishing pads?
Diamond Pads Factory (KAIYI) offers factory-direct diamond polishing pads with wholesale pricing. No middleman markup. Free samples for qualified B2B buyers. Ships globally from Quanzhou, Fujian, China.
Do you use water with diamond polishing pads?
Wet diamond polishing pads require water for cooling and dust control. Dry diamond polishing pads are designed with honeycomb segments for air cooling and require no water. Check your pad type before use.
How to clean diamond polishing pads?
Rinse pads with clean water after each use to remove stone slurry. For resin bond pads, avoid aggressive brushing. Allow pads to air dry completely before storage. Replace pads when the diamond layer is worn below 1mm.
What are the best diamond polishing pads?
The best diamond polishing pads depend on your application. For granite — high-temperature resin bond. For marble — non-staining white bond. For concrete — metal bond for grinding, resin bond for polishing. KAIYI offers OEM customization.
How to use diamond polishing pads on granite?
Start with 50 grit for shaping and saw mark removal. Progress through 100 → 200 → 400 → 800 → 1500 → 3000 grit. Use wet polishing pads with water feed for best results on granite. Keep RPM at 3,000-4,500. Break in new pads on a scrap piece for 30-60 seconds.
How to polish granite with diamond pads?
Begin with coarse diamond pads (50-100 grit) for lippage removal. Move to medium grits (200-400) for honing. Finish with fine grits (800-3000) for mirror polish. Wet diamond polishing pads recommended for granite.
How to polish marble with diamond pads?
Use non-staining white bond diamond pads for marble. Start at 100 grit to remove scratches and etching, then progress 200 → 400 → 800 → 1500 → 3000 grit. Always use wet polishing for marble — dry heat can cause thermal shock. Light pressure only.
How to use diamond polishing pads on marble?
Begin with 100 or 200 grit on marble (skip 50 unless there is severe damage). Marble is softer than granite, so use lighter pressure. White resin bond pads prevent gray discoloration on Carrara, Calacatta, and Thassos marble.
How to use dry diamond polishing pads?
Run at 3,000-6,000 RPM with light to moderate pressure. The honeycomb segments draw in air for cooling — keep the pad moving, do not dwell in one spot. Allow the pad to cool between passes. Break in new dry pads on scrap stone. Always wear P100 respirator.
Can you use wet polishing pads dry?
No. Wet diamond polishing pads rely on water for cooling. Using them dry will cause rapid heat buildup, pad delamination, and stone damage. If you need dry capability, use KAIYI dry diamond polishing pads with honeycomb cooling design.
How to use diamond hand polishing pads?
Diamond hand pads are used for edge profiling, seam blending, and detail work. Hold the pad flat against the surface with consistent pressure. Start with coarser grits and work through to finer grits. Use wet for best results on granite and marble.
How to clean polishing pads by hand?
Rinse thoroughly with clean water immediately after use. Use a soft brush to gently remove stone slurry. Air dry completely before storing. Do not stack wet pads together.
