Liquid Steel Kit with Gun is a professional-grade epoxy crack repair system designed to be injected into concrete cracks to repair and prep cement surfaces for decorative coatings. This complete kit provides everything needed for precise crack injection, including a dual-cartridge applicator gun, three Liquid Steel epoxy cartridges, and six mixing tips. The two-component epoxy creates a permanent, high-strength bond that stabilizes cracks and restores structural integrity in both horizontal and vertical surfaces. It is ideal for use before applying decorative concrete systems.
