Strip industrial paint and sealers with PCD diamond tooling, not metal bond. PCD shears epoxy, polyurethane, and acrylic sealers off in sheets. Expect 200-500 m2 per day on a push grinder, then follow with a 30/46 metal-bond cleanup pass to profile the slab for the new coating.
A metal-bond disc tries to grind through sealer, but the resin softens and loads the segment. PCD (polycrystalline diamond) does not soften: it chips and peels the coating. Our Redi-Lock PCD discs is built for this exact job.
| Coating | Thickness | PCD rate (m2/hr) |
|---|---|---|
| Acrylic sealer | thin | 40-60 |
| Epoxy paint | 100-300 microns | 25-40 |
| Heavy epoxy build-up | 1-3 mm | 10-20 |
| Polyurethane topcoat | thin | 30-50 |

For small rooms, yes. For a 500 m2 plant floor, grinding is faster and avoids chemical disposal.
No. PCD removes the coating, not the concrete. It leaves a light scratch that metal bond cleans up.
When you see uniform gray concrete instead of coating color.
Industrial sealer removal is a PCD job. Strip, cleanup, vacuum, then re-coat. contact JOY TECH for PCD discs sized to your grinder.
