Technical Specifications:

Grit Selection Guide:

• Grit 50 & 100: Coarse grinding, saw mark removal, surface damage repair.
• Grit 200 & 400: Honing, surface refinement, scratch removal.
• Grit 800 & 1500: Polishing, gloss development.
• Grit 3000: Mirror finish, final buffing stage.

Suitable Materials:

• Granite — ideal for edge polishing and sink cutout finishing.
• Marble & Travertine — gentle resin bond protects delicate stone surfaces.
• Quartz — non-staining formula safe for engineered stone.
• Concrete & Terrazzo — effective for detail work and tight corners.

Usage Tips

• Always maintain continuous water flow — never use wet pads dry.
• Start from the lowest grit and work progressively to higher grits.
• Apply moderate, consistent pressure — let the diamonds do the work.
• Rinse pad and surface between grit changes.
• Break in new pads on scrap stone for 30–60 seconds before use on finished surfaces.

Technical FAQ

Why use 2-inch pads instead of 4-inch pads?
2-inch pads are essential for precision finishing in tight radii — specifically for undermount sink cutouts, backsplash corners, and curved edges where 4-inch pads cannot reach.

What RPM is recommended?
Use a max of 4,500 RPM. High-speed grinders should be throttled down to prevent resin burning and ensure effective mechanical polishing.

Are these pads safe for white marble and light-colored quartz?
Yes. The high-grade light-colored resin bond is non-staining, ensuring no dark resin residue transfers to porous light-colored stones.

Do you offer wholesale or OEM pricing?
Yes. Contact us via the Contact page or Wholesale page for bulk and custom orders.

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.

What pad do you use to polish concrete floors?

For concrete floors: metal bond diamond pads (30-100 grit) for aggressive grinding and lippage removal, then transition to resin bond pads (200-3000 grit) for polishing. KAIYI offers both metal and resin bond concrete polishing pads.

Are granite and concrete polishing pads different?

Yes. Concrete pads typically use a harder bond matrix designed for abrasive concrete surfaces. Granite pads use softer resin bonds optimized for hard natural stone. Concrete polishing often requires metal bond pads for the initial grinding stages.

Should you wet polishing pads?

Wet diamond polishing pads must be used with water — it cools the pad, reduces dust, and improves finish quality. Dry diamond polishing pads are specifically designed with honeycomb segments for air cooling and should be used without water.

How to use wet diamond polishing pads?

Connect your polisher to a water source. Set water flow to a light, continuous stream — enough to carry away slurry but not so much that the pad hydroplanes. Run at 3,000-4,500 RPM. Keep the pad moving. Clean the surface between grits.

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.
