Concrete Floor Polishing Pucks Sharp Diamond Copper Bond Grinding Disc

In this review the ComeFloor Concrete Floor Polishing Pucks are evaluated for contractors and facilities teams who need a reliable transitional polishing tool. The bottom line: these 3 in hook-and-loop diamond copper discs deliver an aggressive, consistent scratch pattern that makes them ideal for the stage between metal bond grinding and resin polishing. They stand out for durable copper-reinforced segments and a 50# grit that efficiently removes metal grinding marks while preparing concrete for further densifying and polishing.

Key Features

• Diamond copper bond: The mix of diamond powder and copper powder provides aggressive cutting to remove scratches left by metal grinding discs.
• Consistent scratch pattern: Produces a uniform surface texture that speeds up subsequent densifying and resin polishing stages.
• Hook-and-loop backing: Easy to attach and remove on compatible grinders for quick pad changes on the job.
• 3 in diameter with 0.3 in thickness: Compact size and working thickness suited for detailed work and edge areas where larger pads cannot reach.
• 9-piece pack: Multiple pads in the kit reduce downtime from wear and help maintain consistent performance across a project.

Who It's For

The ComeFloor polishing pucks are aimed at professional concrete grinders and maintenance crews using ride-on or walk-behind grinders who need a transitional tool to bridge metal bond grinding and final resin polishing. They work well for contractors who run machines from manufacturers like Sase, Lavina, Edco, HTC, and Werkmaster and require pads that grab and remove grinding marks quickly.

Those seeking a final high-gloss finish without intermediate steps should look to resin polishing tools instead, and hobbyists with only occasional small repairs may not need a full 9-piece industrial pack.

Pros & Cons

Pros

• Durable copper-reinforced diamond segments remove metal grinding scratches effectively.
• Hook-and-loop backing enables quick changes and compatibility with many fast-change systems.
• Consistent scratch pattern simplifies the transition to densifying and resin polishing.

Cons

• At 3 in diameter these pucks are small for large open areas and require more passes than larger discs.
• They are a transitional tool and not intended to produce final high-gloss finishes on their own.

Frequently Asked Questions

Are these pads compatible with my grinder?
They fit most hook-and-loop systems and list compatibility with common brands like Lavina, Edco, HTC, Werkmaster and others.

What stage of polishing are they for?
They are designed as a transitional stage after metal bond grinding and before resin polishing to prepare the surface for densifying.

How long do the pads last?
Durability is good due to the copper-reinforced diamond bond, but life varies with concrete hardness and machine pressure.
