Product Description

1. Problem: "Gumming Up" on Sticky Mastics and Elastomeric Coatings

 

 

  • The Problem: When renovation contractors attempt to remove thick, rubbery carpet mastics, VCT tile glues, or elastomeric waterproofing membranes from concrete, standard Double Row or Turbo grinding wheels fail immediately. The friction heat melts the sticky glue, turning it into a paste that coats the diamonds. The wheel "gums up" (loads), completely losing its ability to grind, and forcing the operator to spend hours burning off the glue with a torch or using toxic chemical strippers.

  • The Result: Ruined diamond wheels, hazardous toxic smoke from burning adhesives, and severe project delays on residential and commercial flooring renovations.

 

2. Cause: Excessive Surface Friction and Lack of Relief Angles

 

 

  • Thermal Melting: Standard flat diamond segments generate immense friction. Because they sit flat against the material, they heat the rubbery adhesives beyond their melting point before they can turn them into dust.

  • No Escape Path: Double concentric rings trap the sticky, melted resin under the wheel, essentially "gluing" the concrete dust to the diamond matrix.

 

3. Solution: Directional Arrow Segments and "Scraping" Action

 

  • Aggressive Arrow-Tooth Geometry: Instead of flat blocks, this 115mm wheel is engineered with sharply angled, directional "Arrow" segments. These leading-edge points act like high-speed miniature plows or chisels. Rather than grinding the material, the arrows aggressively scrape, shear, and peel thick, sticky coatings off the concrete.

  • Anti-Clogging "Open" Design: The wide spacing between the arrow segments provides massive relief angles. This allows large chunks of stripped glue, epoxy flakes, and rubberized coatings to be instantly evacuated from the cutting zone by centrifugal force, keeping the wheel cool and 100% clog-free.

  • 115mm Agile Footprint: At 4.5 inches, this wheel is the perfect balance of size and maneuverability. It fits universally onto high-speed 115mm angle grinders, allowing operators to rapidly strip stubborn glues in tight residential spaces, kitchens, and bathrooms where large floor machines cannot reach.

5. Professional Industry Applications

 

 

  • Adhesive & Mastic Stripping: The definitive tool for peeling off black mastic, vinyl plank (LVP) glue, and thick carpet adhesives without gumming up the grinder.

  • Thick Coating Removal: Rapidly scraping away failing polyurea, thick garage epoxies, acrylic sealers, and painted traffic lines.

  • Aggressive Concrete Profiling: Creating a heavily textured, highly porous concrete surface profile (CSP 3 to 4) to ensure maximum mechanical bonding for new epoxy or overlays.

 

 

6. Operation and Safety Guidelines

 

 

  • Strict Directional Mounting: Arrow segment wheels are unidirectional. You MUST mount the wheel so the points of the arrows face the spinning direction of your angle grinder. If mounted backward, the wheel will drag flatly, melt the glue, and wear out instantly.

  • Pulsing the Trigger: If you are removing extremely thick, soft rubbery coatings, do not hold the grinder continuously in one spot. Use a sweeping motion and occasionally "pulse" the tool to let air naturally cool the diamond segments, preventing the rubber from reaching its melting point.

  • Silica & Chemical Dust Masking: Stripping old mastics often releases volatile organic compounds (VOCs) and hazardous concrete dust. A specialized HEPA dust shroud and a proper respirator are absolutely mandatory, especially in enclosed residential spaces.

 

7. FAQ: Expert Technical Support

 

 

Q: I have a concrete floor with thick glue. Should I use the Double Row or this Arrow wheel?

 

A: Always use the Arrow wheel first. The Arrow segments will act like chisels to quickly scrape off the thick, sticky glue without clogging. Once the glue is removed and you are down to bare concrete, you can switch to a Double Row or Turbo wheel to smooth and level the slab.

 

Q: Does the Arrow wheel leave a smooth finish on the concrete?

 

A: No. The Arrow segment is a highly aggressive "roughing" tool. It is designed to strip coatings and will leave deep, visible scratches (a heavy profile) in the concrete. This rough texture is actually excellent if you plan to pour self-leveling compound or new epoxy, but it is not suitable for polished concrete.

 

Q: Can I use this 115mm arrow wheel on a 5-inch (125mm) dust shroud?

 

A: Yes. A 115mm wheel will fit safely inside a 125mm dust shroud. However, because there is a 5mm gap around the perimeter, the vacuum suction might be slightly less efficient than using a perfectly matched 125mm wheel. Ensure your HEPA vacuum is running at maximum power.

 

Q: Why does this wheel seem to bounce or vibrate more than my Turbo cup wheel?

 

A: The "biting" action of the directional arrows aggressively digs into the concrete and coatings, which naturally produces more feedback and vibration than a smooth, continuous Turbo wheel. Maintain a firm, two-handed grip on the grinder and let the high RPMs do the cutting.
