100mm Resin Bond Dry Polishing Sanding Disc 50 Grit for Concrete Floor Grinding Surface Preparation
100mm Resin Bond Dry Polishing Sanding Disc – Concrete Floor Grinding Expert
The WNRLN 100mm Resin Bond Dry Polishing Sanding Disc is purpose-built for concrete floor surface preparation and dry grinding applications. Its diamond-impregnated resin bond matrix provides aggressive stock removal at 50-grit coarseness while delivering a controlled scratch pattern that blends smoothly in subsequent finishing steps. The quick change hook and loop backing enables fast disc swaps, maximizing productivity on large-area jobs.
Key Features
- Resin Bond Diamond Matrix: Diamond grit uniformly dispersed in a flexible resin bond that wears progressively, continuously exposing fresh cutting edges for consistent performance throughout the disc's service life.
- 50-Grit Coarse Grinding: Optimized for heavy material removal—ideal for removing old coatings, leveling uneven concrete, and aggressive surface profiling prior to finer polishing stages.
- Dry Operation Design: Formulated to dissipate heat effectively during dry grinding, eliminating the need for water while preventing resin glazing and surface burn marks on the substrate.
- Quick Change Hook and Loop Backing: Peel-and-stick mounting system compatible with standard 100mm backing pads. Enables rapid disc changes without tools, reducing downtime on multi-step grinding sequences.
- 100mm Diameter: Universal 4-inch size fits handheld angle grinders and floor grinding machines, balancing coverage area with operator control for edge and corner work.
Applications
- Concrete floor grinding and leveling
- Removal of epoxy, paint, and floor coatings
- Terrazzo and screed surface preparation
