2" Wet Diamond Polishing Pads, Granite Marble & Concrete | KAIYI

2" Wet Diamond Polishing Pads — Precision Finishing for Stone & Concrete

Engineered for tight spaces and edge work, KAIYI 2-inch wet diamond polishing pads deliver professional-grade results on granite, marble, quartz, and concrete surfaces. The compact 2" diameter is ideal for sink cutouts, countertop edges, and detailed stone fabrication where larger pads can't reach.

Key Features

• Diameter: 2 inches (50mm)
• Working Layer: 3.0mm
• Diamond Grade: Grade A
• Max RPM: 4,500 RPM
• Use: Wet only — always use with water for best results and pad longevity
• Backing: Standard hook-and-loop (Velcro) — fits most angle grinders and polishers
• Resin: Light-colored, non-staining resin bond — safe for light-colored stones
• Grit Range: 50 – 3000

Engineered for Professionals

Our 2" wet diamond pads are a staple in stone fabrication shops across North America. Specifically optimized for granite edge profiling and concrete countertop restoration, the 3.0mm diamond layer provides 25% more usable life than standard 2.0mm pads — making them the most cost-effective solution for high-volume sink cutout projects.

Grit Guide — Full Polishing Sequence

• Grit 50 — Coarse Grinding: removes scratches, saw marks, and surface damage
• Grit 100 — Medium Grinding: levels surface and removes Grit 50 scratches
• Grit 200 — Fine Grinding: smooths surface, prepares for honing
• Grit 400 — Honing: refines surface, removes fine scratches
• Grit 800 — Pre-Polish: develops initial sheen and clarity
• Grit 1500 — High Polish: brings out deep gloss and transparency
• Grit 3000 — Mirror Finish: achieves maximum reflectivity and gloss

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 Instructions

• Always use with water — wet polishing extends pad life and prevents heat damage
• 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
• Compatible with standard 2" hook-and-loop angle grinders and polishers

Frequently Asked Questions

Q: Why use 2-inch diamond pads instead of standard 4-inch pads?

2-inch diamond polishing pads are essential for precision finishing in tight radii, specifically for undermount sink cutouts and tight backsplash corners. While 4-inch pads are for flat surfaces, the 2-inch diameter prevents over-grinding on curved edges and provides better visibility for detail work.

Q: What is the recommended RPM for 2-inch wet polishing pads?

For optimal results and pad longevity, use a max RPM of 4,500. High-speed grinders should be throttled down to prevent resin burning and ensure the diamond grit performs effective mechanical polishing rather than heat-induced glazing.

Q: Are these pads safe for white marble and light-colored quartz?

Yes. Our pads use a high-grade, light-colored resin bond that is specifically formulated to be non-staining. This ensures that even under the friction of high-grit polishing (1500–3000), no dark resin residue is transferred to porous light-colored stones.

Q: Can I skip grits in the polishing sequence?

For a professional mirror finish, we recommend following the full sequence: 50, 100, 200, 400, 800, 1500, to 3000. Skipping more than one grit stage can leave microscopic scratches that reduce the final gloss level of the stone.
