Direction for Use

Surface Preparations

• Prepare the surface to be treated by removing any dust, laitance, grease and oil or any pre-existing finish.

Application

• Remove the pipe repair tape from the foil pouch and immerse in water for a few seconds, squeezing the roll as you do this to begin to activate the epoxy.
• Place the tape/ bandage over the repair area and begin to wrap this tightly around the pipe, overlapping as you go and ensuring the repair area is completely covered.
• Once complete, massage the wrapped pipe area using wet gloves and continue to massage for approximately 5 minutes until the repair is smooth.

Curing

• Allow to cure for a minimum of 30 minutes – for best results leave for 2 hours.

Limitations

• Do not open the repair tape/ bandage foil pouch before you are ready to use it as this can cause it to ‘cure’.
• If using multiple tapes these should applied consecutively at the time of conducting the repair and before massaging the repair.

Coverage

•  Coverage is dependent on pipe repair, pipe diameter and leak pressure.
