Introduction

When you’re in the business of honing and polishing concrete, marble, granite, quartz, and other natural stone, using the right tools is critical. Diamond polishing pads have become the go-to solution for contractors, stone fabricators, and tool distributors because of their efficiency and the superior finish they deliver.

What Are Diamond Polishing Pads and How Do They Work?

Diamond polishing pads are abrasive discs embedded with industrial-grade diamond particles. These pads are designed to attach to variable-speed polishers or grinders and are used to gradually grind and polish surfaces to a high-gloss finish.

Wet vs. Dry Diamond Pads – What’s the Difference?

Wet Diamond Pads:

• Use water as lubricant

• Reduce heat and increase pad life

• Ideal for marble and large jobs

Dry Diamond Pads:

• No water needed

• Ideal for indoor/small areas

• Generate more heat and wear

Some pads are labeled “wet/dry” – always monitor heat during use.

Types of Diamond Polishing Pad Bonds

Metal-Bond Pads:

• For aggressive grinding

• Durable and ideal for initial stages

Resin-Bond Pads:

• Flexible and used in polishing stages

• Available in grits from 50 to 3000+

Hybrid-Bond Pads:

• Bridge between metal and resin pads

• Used in transitional honing phases

Concrete Polishing Best Practices

Stages:

1. Grinding (30–70 grit): Remove coatings and level surface

2. Honing (100–200 grit): Smooth and prepare for polish

3. Polishing (400–3000 grit): Achieve desired gloss

Tips:

• Use pads formulated for concrete

• Apply densifier between honing and polishing

• Use overlapping passes and control speed

Marble Polishing Tips

Grit Progression:

• 50–200: Prep and lippage removal

• 400–800: Honing

• 1500–3000+: Polishing and buffing

Recommended Tools:

• Wet resin-bond pads from Johnson Tools

• Buffing compound or crystallizer spray for high gloss

Granite Polishing Guidelines

Grits:

• Follow full sequence: 50, 100, 200, 400, 800, 1500, 3000

• Optional: Buff pad + compound for added clarity

Tips:

• Use pads designed for granite hardness

• Hand pads for edges and inside curves

Johnson Tools Pads:

• Hard resin-bond for long-lasting granite polish

Quartz (Engineered Stone) Considerations

Best Practices:

• Wet polishing only – avoid heat damage

• Start at 200 or 400 grit for repairs

• Lighter resin pads prevent staining

Johnson Tools Recommendation:

• 4" quartz pads, often labeled for marble use too

Polishing Softer Stones (Limestone, Sandstone)

Approach:

• Stop at 400–800 grit for natural look

• Use soft resin pads

• Wet polish with light pressure

Finishing:

• Use sealers/enhancers to protect and enrich color

Diamond Pad Grit Guide

Pro Tips for Better Polishing

• Keep pad flat and pressure even

• Use correct size pads for your machine

• Clean between each grit change

• Always use wet polishing if possible

• Seal surfaces post-polishing for durability
