CST-22 Gun. Concrete Repair Crack Treatment Gun. Fast Cure Urethane

The CST-22 gun designed to load two CST-22 cartridges at once, and then combine the contents into one stream in the tip in order to fill cracks in concrete.

 

How to Use

  1. Use a diamond turbo blade to open up the crack and remove any loose concrete debris.
  2. Clean the squared concrete with compressed air to remove dust from grinding.
  3. Fill the crack with clean, dry sand until the surface is flush and level.
  4. Shake the cartridge for a minimum of 30 seconds, remove the cap and install the flow restrictor on top of the ports. Insert the assembled dual cartridge into the gun.
  5. Point the gun up, and gently squeeze the trigger to release the trapped air in the tip. Then continue squeezing and release a small amount of material to make sure the two cartridges are properly mixing.
  6. Apply CST-22 into the crack while applying even pressure on the trigger to dispense the proper amount of each material.
