Wait at least 7 days after pouring (28 days for full cure) before dry diamond grinding. At 3 days you can wet-grind very lightly only if the slab can support the machine; grinding too early pulls aggregate out and burns the bond.
Grinding too early can ruin an otherwise good slab — aggregate pops out, the surface dusts, and the warranty is voided. Timing is everything.

Use a soft bond on hard, dense concrete; use a hard bond on soft, abrasive concrete. When segments glaze over too fast you need a softer bond; when they wear in minutes you need a harder bond.
No — aggressive metal-bond shoes are for early grinding, and resin-bond pads are for polishing stages. Mixing them wastes diamonds and ruins the scratch pattern.
Yes. JOY TECH manufactures trapezoid grinding shoes, PCD grinding shoes and cup wheels in custom bonds, sizes and segment shapes for global distributors and floor prep contractors.
Getting consistent results on a concrete floor comes down to matching the right diamond tool, bond and grit sequence to the job — and avoiding the common mistakes that scratch, glaze or gouge the slab. For OEM/ODM grinding shoes in your own brand, contact JOY TECH today.
