Frequently Asked Questions

Does this listing include all six micron grades?

No. Each micron grade is sold separately in a pack of 10 sheets. Select the grade you need from the available options.

Which micron grade should I choose?

Lower micron numbers provide a finer abrasive finish, while higher micron numbers remove material more aggressively. Choose 30 or 15 micron for initial surface refinement, then progress through finer grades as needed.

Can these polishing sheets be used wet?

Yes. These sheets are designed for both wet and dry sanding and polishing.

What is the difference between aluminum oxide and silicon carbide grades?

The 1, 2, 3, and 9 micron grades use aluminum oxide abrasives. The 15 and 30 micron grades use silicon carbide abrasives. Both provide controlled surface refinement for a variety of materials.

Can I cut these sheets into smaller pieces?

Yes. The flexible sheets can be cut into strips for sanding sticks or adapted into bands for compatible finger sanders.

Are these suitable for curved surfaces?

Yes. The flexible backing conforms to both flat and contoured surfaces, making these sheets useful for detailed finishing work.
