4" 3-Step Wet Diamond Polishing Pads for Concrete & Terrazzo — Fewer Pad Changes, Faster Floors
Our 4" 3-Step Wet Diamond Polishing Pads are specifically engineered for wet concrete grinding and terrazzo polishing, consolidating the traditional 7-step sequence into three stages for a professional high-gloss finish. Designed for contractors who need to move fast on large floor projects without sacrificing finish quality.
Key Features:
🚀 3-Step Efficiency: Consolidates the traditional 7-grit sequence. Fewer pad changes per slab reduces labor time on large-scale concrete floor projects.
💎 Designed for Concrete & Terrazzo: Specialized resin bond formulated to handle concrete abrasiveness while maintaining controlled cutting temperature.
🌊 Wet Use: Optimized for wet polishing to eliminate dust, prevent burning, and achieve a deeper finish.
🌀 Advanced Segment Design: Flower, star, and hexagon segment options for efficient slurry ejection and reduced clogging.
🛡️ Grade A Industrial Diamonds: High-concentration diamond powder for consistent cutting performance.
The 3-Step Workflow:
- Step 1 (Coarse): Aggressive grinding, leveling, and removal of deep scratches.
- Step 2 (Medium): Honing and refining to a smooth matte finish.
- Step 3 (Fine): Final high-gloss buffing for a mirror-like finish.

Usage Tips
- Hard concrete (5,000+ PSI): Use Step 1 at 2,000 RPM with steady water flow to keep diamonds cutting aggressively.
- Medium concrete: Step 2 at 2,500–3,000 RPM delivers a smooth honed surface ready for final buffing.
- Terrazzo: Wet mode throughout all 3 steps prevents aggregate pullout and ensures a uniform finish.
Technical FAQ
Can these pads be used dry on concrete?
Not recommended. Water is essential to control dust, prevent burning, and maximize pad life on abrasive concrete surfaces.
Are these compatible with floor grinders?
These 4" pads are designed for hand-held angle grinders. For large floor grinding machines, contact us for our floor machine pad range.
What is the difference between CUST-05 (3-Step Concrete) and CUST-04 (3-Step Granite/Marble)?
CUST-05 uses a medium-hard bond formulated for concrete abrasiveness. CUST-04 uses a medium-soft bond suited for granite and marble. Using the wrong bond on concrete will cause rapid wear.
Factory Direct — OEM & Bulk Orders Available
MOQ: 100 pcs. Custom branding on Velcro and specialized formulas for different concrete hardness (Hard/Medium/Soft) available upon request.

Frequently Asked Questions
How is concrete polishing different from stone polishing?
Concrete uses a medium-hard resin bond to handle its abrasiveness. Stone polishing uses a softer bond. Using a stone pad on concrete causes rapid wear. CUST-05 is specifically formulated for concrete and terrazzo — not interchangeable with granite/marble pads.
Do I need a densifier when using these 3-step pads on concrete?
Yes. Apply a lithium silicate densifier after Step 1 (coarse grinding) and before Step 2. Without densifier, the concrete surface stays porous and the final gloss will be dull. This is the most common mistake in DIY concrete polishing.
Can these 3-step pads replace a 7-step sequence on concrete?
For most commercial concrete (3,000–5,000 PSI), yes. The 3-step system delivers comparable results with fewer pad changes. For very hard concrete (5,000+ PSI) or decorative terrazzo requiring maximum aggregate clarity, a 7-step sequence may still be preferred.
