1. Surface Preparation 

Remove all soft coatings and media blast the pipe to a 2.5 mil profile (NACE 3 minimum). Wipe the surface with a solvent such as Acetone, Toluene, or MEK.


2. Load Transfer Filler 

Mix the putty or paste until uniform in color and apply to any defects. Shape the filler to near net surface profile of pipe.


3. Adhesive Primer 

Mix equal parts of the adhesive primer until uniform. Apply the primer to the pipe surface, ensuring a minimum of 30-mil coverage. Allow the primer to sit until a “peanut butter” thickness is achieved.


4. Preparing the Wrap

Mix epoxy parts A and B for at least 2 minutes. Apply the mixed resin onto the fabric evenly distribute on the fabric. Roll up the fabric and transfer to the prepared pipe.


5. Apply Wrap to Pipe

Apply cloth tightly around pipe and continue wrapping until designed layer count is achieved.


6. Constrictor Wrap


Tightly apply 4-6 layers of constrictor wrap over the repair. Then, perforate the surface of the wrap. Allow 2 hours for curing.


7. Topcoat Application 

After the epoxy has cured, remove the constrictor wrap. Apply a topcoat to the repair area, as applicable.
