SEALXPERT POLYETHYLENE TAPE APPLICATION PROCEDURE:

1
1. Coating the pipe surface with SealXpert Primer.
2
2. Apply SealXpert Poly Inner Wrap 980. Start at the 9 o’ clock position. Ensure that the adhesive side of tape is to the substrate.
3
3. Starting a new roll of tape. Overlap ends of tape by one tape width. Overlapping each turn by 55% gives a double thickness.
4
4. Use SealXpert Poly Outer Wrap as the final wrapping tape
