How long does it take for J-B Weld to set?

Make sure to work quickly, as the J-B WELD sets very fast. Apply your mixed J-B WELD all over the leak area liberally with the wooden tool. The mixture will set in 4 to 6 hours and be completely cured in 15 to 24 hours. Replace the radiator plug on the bottom of the radiator and refill the fluid to the appropriate level.
