Concrete Joint Cutter - Ninja Joint Cleaning Blades

Designed for contractors removing failed joint sealant and debris from control joints before resealing operations, the Ninja Joint Cleaning Blades from Diamond Products deliver consistent cutting performance in both fresh and cured concrete. These specialized blades remove old elastomeric sealants, dirt accumulation, and damaged joint edges to establish clean sidewalls for proper adhesion of new sealant materials. The blade configuration handles joints in warehouse floors, parking structures, and plaza decks where seasonal movement requires periodic maintenance. Use with standard walk-behind saws or handheld grinders depending on joint depth and accessibility requirements. Each blade maintains cutting depth consistency to avoid damaging the joint reservoir geometry. Built for concrete restoration crews and facility maintenance teams handling recurring joint repair schedules.
