Fitment Note

Before ordering, confirm your machine type, backer pad size, hook-and-loop backing requirement, polishing method, and required quantity.

Use this pad with a compatible 4 inch hook-and-loop backer pad. Do not order by diameter alone; confirm that your wet polisher, handheld grinder, or backer pad setup accepts 4 inch polishing pads.

If fitment is unclear, check adapters and plates or send your machine model and backer pad photo through Contact Us.

Polishing Workflow

Use this pad set after shaping, grinding, or earlier surface preparation is complete. Start with lower grits when scratch removal is needed, then move step by step to finer grits for refinement and finish development.

For concrete or terrazzo floors that still need heavy preparation, use metal bond grinding tools before polishing.

If visible scratches remain before final polishing, use hybrid pads to refine the scratch pattern.
