Concrete Joint Cutter - Ninja Joint Cleaning Blades

Cleaning out control joints and saw cuts before sealing requires blades that won't damage existing concrete while removing debris and old sealant. These Ninja Joint Cleaning Blades from Diamond Products handle the precise work of preparing joints for fresh sealant application. The blade design cuts through compacted dirt, failed sealant material, and vegetation without widening the joint or chipping edges. Use them to restore expansion joints in parking structures, warehouse floors, and commercial slabs where proper joint maintenance prevents water infiltration and extends concrete life. The cutting action clears joints to proper depth for new backer rod and sealant installation. Built for concrete restoration contractors and maintenance crews who need clean joints for reliable sealing work.
