HDPE Pipe Repair Steps:

  1. Rough the HDPE around the problem area with sandpaper.
  2. Drill a hole at each end of the crack so that internal pressure will not cause the crack to expand.
  3. Clean with any cleaner that will not leave a residue. Dry thoroughly. Apply Poly Prep adhesion promoter on the area of pipe to be bonded.
  4. Spray the Activator/Accelerator (AA) on the prepped area. Let the AA dry.
  5. Apply the SI Blue to the Tech-Patch with continuous circles EXCEPT on diagonal corners. Paying special attention to having the adhesive reach the edges.
  6. Grab the diagonal corners on the Tech-Patch, apply tension.
  7. Press the Tech-Patch to the problem area on the HDPE.
  8. Use the glue squeegee to apply firm pressure to the Tech-Patch from the center out.
  9. Bond the diagonal edges to the HDPE with the SI Blue Spray with AA.
  10. Apply a bead of the SI Blue to the perimeter of the Tech-Patch. Spray with AA.
  11. Visually inspect.
