Features and Advantages

  • Treats moving cracks
  • Used to fill tooled interior/exterior control joints or new construction saw joints on horizontal concrete surfaces
  • Protects joint edges from spalling due to wheeled traffic

  • Minimum depth can be reduced to 1/2 in. (13 mm), for foot traffic
  • May be used for exterior applications when minimal joint movement from thermal cycling will occur
  • Keeps joints free of debris and provides a continuous surface for weight loading

  • VOC compliant formulations
  • Shore A hardness supports traffic
  • Self-leveling, low viscosity system
  • 18 month shelf life
