Applications

Suitable for concrete polishing, surface refinement, and preparing the slab for additional polishing steps.

How to Use

1. Choose the correct grit and diameter for your application.
2. Thread the polishing cup securely onto the grinder spindle.
3. Maintain a steady RPM and do not force the cup. Keep it moving in a smooth, consistent motion to help achieve an even scratch pattern.
4. Ensure the grinder is in good condition. A clean, straight spindle and flange will reduce wobble and uneven wear.

Tips & Tricks

• Inspect your grinder’s bearings, spindle, and dust shroud. A bent spindle or dirty flange can cause wobble and uneven wear.
• If using with a dust shroud, make sure there’s only a small gap (around 1/8”) between the shroud and the floor for optimal vacuum suction.
• Follow up with the next polishing step or finer grit as needed for your desired finish.
