Concrete Polishing Pads by Grit Sequence

Concrete floors are polished in stages: grind to level, hone to refine, polish to shine. Each stage uses a progressively finer grit — skipping stages leaves swirl marks that the fine pads cannot remove.

DIAMTO concrete pads are specified for grinding and polishing concrete, in wet or dry use depending on the SKU. The table below lists the real, orderable range with sizes and grit options from the product master.

How to build your grit sequence

  1. Start with the floor condition

    New or flat floors can start finer; damaged, coated or uneven floors need coarse grinding first. Match the starting grit to the worst defect, not the average surface.

  2. Follow the stage logic

    Grinding (coarse) → honing (medium) → polishing (fine). Move up only when the previous grit has removed the scratches of the one before — inspect under raking light.

  3. Choose wet or dry per SKU

    Some SKUs are specified wet/dry, others dry-only (e.g. superhard-concrete and floor-polishing variants). Check the application column before ordering.

  4. Size the pads to the machine

    3 inch pads suit edge grinders and small areas; 4 inch pads are the standard for walk-behind and planetary machines with the right backing.

Frequently asked questions

Wet or dry — which should I choose?

Wet use controls dust and cools the pad; dry use is faster on site but needs dust extraction. Several SKUs are specified for both; superhard-concrete variants are dry-use.

How many steps to a high-gloss concrete floor?

Typically 6–8 steps from grinding to polishing. The exact count depends on the starting condition — tell us about the floor in your RFQ and we will suggest the sequence.

What are transitional polishing pads?

Transitional pads — copper-bond or ceramic-bond — sit between metal-bond grinding discs and resin polishing pads in a concrete sequence: they erase the deep scratches left by metal tooling so resin pads can start at a finer grit. Whether your floor needs them depends on the slab and the sequence; describe the job in your RFQ and we will recommend the right tooling from our grinding and polishing range.

Can I use these pads on terrazzo?

Terrazzo responds to the same grind-hone-polish logic as concrete. Our concrete pads are specified for grinding and polishing concrete and stone floors — tell us whether the terrazzo is cement- or resin-based in your RFQ and we will confirm the starting grit.

What is the minimum order quantity (MOQ)?

The standard MOQ is 100 pieces per SKU. Mixed-grit sets can be combined within one order — tell us the grit breakdown you need in the RFQ.

What is the lead time?

Standard lead time is 15–30 days after order confirmation. Samples and repeat orders are usually faster. Sample orders and small quantities can ship by air freight to shorten delivery time.

Do you offer OEM / private label?

Yes. OEM and private-label production is available, including custom packaging. Send your artwork or requirements with the inquiry.

How fast do I get a quote?

We reply to RFQs within 24 hours on business days. The more detail you give (SKU, size, grits, quantity), the faster the quote.

I’ve never imported from China before. Can I still order?

Yes — many of our customers placed their first China order with us. Mention it in your inquiry and we’ll recommend freight forwarders experienced with small B2B shipments, and help you plan the order step by step.
