Concrete Joint Cutter - Ninja Joint Cleaning Blades

Cleaning out control joints and expansion cuts before sealant application requires blades that remove old material without damaging concrete edges. These Ninja Joint Cleaning Blades from Diamond Products handle the dirty work of clearing debris, failed sealant, and compacted dirt from existing joints in parking lots, warehouse floors, and commercial slabs. The blade design cuts through hardened material while maintaining clean vertical walls in the joint. Works with standard joint cutters to prepare joints for proper resealing, extending pavement life and preventing water intrusion. Saves time over manual cleaning methods like wire brushes or chisels when you're prepping hundreds of linear feet. Built for concrete contractors and maintenance crews handling joint restoration work on existing flatwork.
