Ecofirm — Professional Abrasives
Trapezoid Grinding Plate — 3 Round Segments
Soft bond diamond grinding plate · 3 round segments · 16 grit and 30 grit · For floor grinders and concrete preparation machines.
The trapezoid shape and 3-point round segment layout provide stable, consistent contact across the full grinding surface — delivering aggressive material removal with even wear across all three segments. Soft bond matrix releases diamonds faster, making it ideal for grinding hard concrete surfaces.

Grit Selection
16 Grit — Heavy removal
Use for removing thick coatings, old adhesive, paint, or leveling significantly uneven concrete surfaces. Maximum stock removal per pass.
30 Grit — General grinding
Best for general concrete surface preparation — opening the surface for coatings, overlays, and epoxy systems without excessive removal.
Key Features
Soft bond matrix
Soft bond releases diamonds continuously as the segment wears — keeps the plate cutting aggressively on hard concrete without glazing over.
3-point round segment layout
Three evenly spaced round segments distribute grinding pressure uniformly — consistent cut depth across the entire plate surface.
Trapezoid plate design
Trapezoid shape provides stable contact on planetary and single-head floor grinders — reduces vibration and plate skip during operation.
Aggressive concrete prep
16 and 30 grit options cover the full range of initial concrete preparation — from heavy stock removal to standard surface opening.
Applications
Concrete surface grinding
Coating & adhesive removal
High spot & laitance removal
Overlay & microtopping prep
Warehouse & commercial floors
Start with 16 grit for heavy coating removal or significant surface leveling, then step up to 30 grit to refine the surface before applying overlays or coatings. Always use dust extraction when grinding concrete.
Soft bond = hard concrete. Soft bond plates are designed for hard, dense concrete. On soft or green concrete, the bond releases too quickly and segments wear prematurely. Use a medium or hard bond plate for softer concrete surfaces.
