Concrete Joint Cutter - Ninja Joint Cleaning Blades

Designed for contractors who need to clean out control joints and saw cuts before sealing, these Ninja Joint Cleaning Blades from Diamond Products remove debris, old sealant, and spalled concrete from expansion joints. The blade configuration cuts clean edges along joint walls, preparing surfaces for proper sealant adhesion in parking structures, warehouse floors, and commercial slabs. These blades work with standard joint cutters to restore joint integrity without damaging surrounding concrete. The system handles both new construction cleanup and maintenance work on existing joints that need resealing. Use them to prep joints before applying polyurethane or silicone sealants in applications where joint performance matters. Built for commercial concrete contractors and facility maintenance crews who maintain large floor systems.
