The EDCO QC2B-HC-0120 is a 120-grit double diamond grinding dot built for hard concrete and sold as a pack of three. Concrete grinding contractors run these Dyma-Dots on EDCO Magna-Trap floor grinders to strip coatings and prep slabs, leaving a clean, level surface ready for the next step. The 120-grit rating delivers a finer scratch pattern for smoothing and refining after coarser passes.
Use Cases
Coating removal. Take off general-purpose epoxy, mastics, thinsets and waterproofing coatings during floor prep.
Leveling and smoothing. Remove high spots and level concrete without gouging, leaving a controlled, even surface.
Surface refinement. Use the 120-grit dots to refine the scratch pattern ahead of finishing or polishing.
Choosing the Right Bond
This QC2B-HC-0120 is the hard-concrete bond. Matching diamond bond to slab hardness is key: harder concrete generally calls for a softer bond and softer concrete a harder bond. EDCO also offers medium and soft concrete versions of this dot if your slab differs.
