4" Wet Diamond Polishing Pads — Full Grit Range for Concrete & Stone Floor Polishing
KAIYI 4-inch wet diamond polishing pads deliver consistent, professional-grade results on granite, marble, quartz, concrete, and terrazzo. Engineered with a high-concentration diamond matrix and non-staining light resin bond, these pads cover the complete polishing sequence from coarse grinding (Grit 50) to mirror finish (Grit 3000) in a single product line.
Key Features:
- Full Grit Range 50–3000: Complete progression from coarse grinding to mirror-gloss finishing in a single product line.
- Wet Use: Continuous water flow cools the pad, suppresses dust, and maximizes diamond exposure for consistent cut rate.
- Non-Staining Light Resin: Light-colored resin bond prevents staining on white marble and light-colored stone.
- High Diamond Concentration: Grade A diamond matrix ensures aggressive cutting at coarse grits and high gloss at fine grits.
- Universal 4" Hook & Loop Backing: Compatible with all standard 4-inch angle grinders and flexible backing plates.

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.
What is the difference between CUST-03 (Concrete & Stone) and CUST-06 (Granite & Marble)?
CUST-03 is optimized for concrete and stone floor polishing — the bond is slightly harder to handle concrete abrasiveness. CUST-06 uses a softer bond specifically for granite and marble countertop and edge work, with a white non-staining formula for light-colored stone.
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 polish concrete floors with wet diamond pads?
Start with Grit 50 for surface preparation and lippage removal. Progress through 100 → 200 → 400 grit. Apply a lithium silicate densifier after Grit 400 and cure 24 hours. Continue with 800 → 1500 → 3000 grit for mirror finish. Use wet method throughout for dust control.
What is the difference between concrete and stone polishing pads?
Concrete pads use a slightly harder bond matrix for abrasive concrete surfaces. Stone pads use softer resin bonds for granite and marble. CUST-03 is formulated to handle both concrete and stone in a single product line.
Can I use these pads on granite and marble as well as concrete?
Yes. CUST-03 is a versatile pad suitable for granite, marble, quartz, concrete, and terrazzo. For dedicated granite/marble countertop work with white stone, CUST-06 (non-staining white bond) is the preferred choice.
