When contractors grind or prep concrete floors, the hardest area to keep consistent is almost always the perimeter: edges, corners, door lines, and tight transitions. A full-size grinder may flatten the field quickly, but edging marks and scratch patterns can ruin the final look—or slow the whole job down.
A repeat customer in Kansas (Sundek of Wichita) asked for a practical solution: a 110V edge grinder that can run common Lavina diamond tooling, plus a simple step-by-step tooling flow that avoids random trial-and-error.
1) The real job problem: edges that don’t match the field
On many coating and resurfacing jobs, crews fight three problems at the perimeter:
• Heavy scratch marks left by aggressive metal tools
• Uneven bite when concrete hardness changes along the edge
• Visible “halo lines” after coating, stain, or polish
The goal is not only removal—it’s control: controlled scratch pattern, controlled flatness, and predictable productivity.
2) The solution: a customized edge grinder that fits Lavina diamonds
This order included a custom 110V edge grinder with a Lavina-fit plate. The key point is compatibility: crews can keep using the same Lavina tooling style they already trust, instead of switching systems.
3) The tooling workflow: Metal → Hybrid (simple and repeatable)
To keep the process fast and consistent, the customer chose:
• Lavina X Metal Grinding Discs (Soft Bond)
• 30 grit (12 pcs) for faster cutting
• 100 grit (12 pcs) to refine scratch pattern
• 3” Hybrid Polishing Pads
• 50 grit (12 pcs) for metal scratch removal
• 100 grit (12 pcs) for surface refinement
• 400 grit (12 pcs) to reduce visible swirl and prep for the next step
Why this matters: hybrid pads are often the “bridge” that saves time. Instead of jumping directly from metal to resin, hybrid tooling helps remove metal scratches efficiently—especially on edges.
4) What to confirm before choosing bond and grit
If you want this workflow to perform on real jobs, confirm three things before ordering:
• Concrete hardness (soft / medium / hard)
• What you are removing (coating, glue, sealer, bare concrete)
• Your target finish (prep for recoat, stain-ready, polish-ready)
5) If you run Lavina tooling and need an edge setup
If your crew already uses Lavina diamonds and you want a dedicated edge system, we can build a Lavina-compatible edge grinder setup and match your metal/hybrid sequence to your concrete conditions.
