Most grinding failures trace back to a bond mismatch, worn tooling, or the way the grinder is being run. Most concrete slab projects run metal-bonded matrix for surface prep (16#-80# grit stage) and resin-bonded matrix for burnishing (100#-3000# grit stage). Use metal-bonded matrix tools for aggressive abrading, coating layer stripping and sawing — they last 5-10x longer and strip material fast.

Metal-bonded diamond tooling use a sintered metal matrix — in most cases copper, iron, cobalt or nickel alloys — that holds diamond particles in place.
This is where most crews get it right - or lose time.
A closer look at the details.
Resin-bonded tools (frequently called resin pads) use a phenolic or epoxy resin matrix with a much softer structure.

Contractors who skip this stage usually end up redoing the floor.

Typical sequence: metal-bonded matrix at 30#-40# to abrade and level → metal-bonded matrix 80# to even → resin-bonded matrix 100#-200# to refine → resin-bonded matrix 400#-800# for sheen → resin-bonded matrix 1500#-3000# for high mirror finish.
Contractors who skip this stage usually end up redoing the floor.
A: For most jobs, No. Resin pads are too soft for coating layer stripping. Use metal-bonded matrix or PCD tools first, then switch to resin for burnishing.
A: In short, Metal-bonded matrix tools typically last 5-10 times longer than resin pads. Resin pads wear because they are designed to break down for a fine finish.
A: The practical answer is, Metal-bonded matrix tools burnish only up to a medium sheen (about 120#-200# equivalent). For a high-gloss finish, you require resin-bonded matrix pads from 400# up.
A: For most jobs, Switch after the surface is level and scratch mark-free from metal abrading (typically after 80#-120# metal-bonded matrix), then start resin burnishing at 100#-200#.
