DONE IN 5 EASY AND VERY FAST STEPS :
#1 Find the leak by using the usual detection methods.
#2 Once the leak is identified, turn off the system, and clean the application area.
#3 Cut with a knife a quantity of Smart Seal External which is enough to create a ring around the entire diameter of the pipe in the area of the leak
#4 Using your fingers mix the two components for a while. The color must be uniform and you should perceive a slight sensation of heat.
#5 Apply the mixture directly on the leak area, let it adhere to the whole circumference with about .5 inches on each side of the leak area. Wait 4-5 hours for the Smart Seal External to cure and harden. Curing can be accelerated with the use of a heat gun. Once the product is dried, let the system run normally again. If you need to remove the product, spray grease/seal remover on it, wait a moment, grab the ring with pliers or spanners with a little pressure that does not deform the pipe and rotate in one direction.
These are standard instructions. Like brazing, there can be many variables that come with sealing holes and cracks in the field with Smart Seal External. This includes material condition, environment, size of leak, pressure of system, and workmanship.
