Troubleshooting

Flat surface stays dull after first-stage polishing

The first-stage route may be too mild for the contact area.

Symptoms

  • The flat surface becomes cleaner but does not become bright.
  • The surface looks dull even after repeated base-route passes.

Likely causes

  • The first-stage route may be too mild for the contact area.
  • Wheel may be overloaded or too soft for the job.

Checks

  • Check whether the surface is prepared to the expected grit.
  • Check wheel cleanliness and contact area.

Recommended fixes

  • Use a more aggressive first-stage route and inspect after short passes.
  • Clean the wheel and avoid adding compound overload.

Prevention

  • Estimate contact area before choosing the first-stage route.
  • Inspect after short passes and avoid indefinite pressure increase.
