Key Features
-
General Purpose Removal: Removes sealers, thin mil epoxies, mastics, thinsets (yellow only), and waterproof coatings without gouging the surface, creating a smooth, level profile.
-
Clean, Smooth Results: Designed to leave only a small amount of fine scratches (Concrete Surface Profile/CSP 1-2) while eliminating the risk of deep trenches or gouges.
-
Omni-Directional Cutting: Allows flexibility for use in all directions, supporting both straight and circular grinding passes for consistent coverage.
-
Magnetic Quick-Change System: Magna-Trap magnetic backing enables effortless, wedge-less changes between toolings—saving significant time during multi-step projects.
-
Bond Options for All Concrete Types:
Performance & Key Benefits
-
Wide Application Range: Suitable for prepping floors for overlays, removing buildups prior to refinishing, and smoothing old or patchy slabs for coatings and sealants.
-
Uniform, Professional Results: No gouging means less repair work, easier cleaning, and better finishes when recoating, polishing, or densifying concrete.
-
Tough, Long-Lasting Construction: High-quality diamonds and durable bonding ensure reliability—especially when matched to the correct concrete type and hardness.
-
Time-Saving Service Intervals: Quick tool swaps and minimized interruptions on busy jobsites, increasing daily coverage and project efficiency.
-
Eco-Friendly: Less aggressive removal with effective dust collection reduces airborne silica and prolongs floor life.
Best Practice Applications
-
Removing sealers, thin epoxy, mastics, or waterproof coatings from warehouse and retail floors.
-
Blending patch repairs with existing slab for seamless overlays or decorative coloring.
-
Prepping surfaces for stains, new coatings, overlays, or densifier treatments.
-
Smoothing newly placed or rain-marked concrete slabs prior to hand finishing or polishing.
Maintenance & Operator Tips
-
Before Use: Match the Dyma-Dot bond to slab hardness for best results (soft bond/red for hard concrete, hard bond/yellow for soft/abrasive concrete).
-
During Use: Rotate tooling between heads every few hours for even wear and to extend life; monitor for vibration or diminished performance and replace as needed.
-
After Use: Clean magnetic backing and multi-tooling disc to ensure full contact and proper magnetic holding power.
-
Vacuum Compatible: Always pair with industrial vacuum and dust shroud system for OSHA standard-compliant silica control and operator safety.
-
Storage: Keep in clean, dry area, and separate colors/bonds for efficient jobsite matching.
Frequently Asked Questions
Q: How many Double Dyma-Dots are needed per grinder?
A: Single-disc or turbo grinders use 3 per head; dual-disc grinders use 6 (3 per head).
Q: Can these prep for overlays as well as removals?
A: Yes, they level substrate for overlays, remove old build-up, and provide a perfect base CSP 1–2 profile for most polymer/resinous flooring systems.
Q: Is there a risk of gouging concrete or leaving "trenches"?
A: No; the Double Dyma-Dot design prioritizes smooth, scratch-minimal removal for professional, uniform results.
Q: Are single Dyma-Dots still available?
A: No. Single Dyma-Dots have been discontinued—Double Dyma-Dots are the current standard for Magna-Trap tooling.
