1. Clean the pipe surface, to be wrapped, of all dirt, rust and foreign elements by the normal wire brush method.
2. Remove about 2" of kraft paper from each end of the mill or yard coating.
3. Apply Protecto Wrap 1170 primer to the cleaned surface with a paint brush and about 2" back on each end of the factory coating.
4. Remove the backing seperator from the tape for about 6" ; when the primer becomes tack free, begin the spiral wrap with the film covered side of the tape up.
5. Remove and discard the backing seperator from the tape as you wrap.
6. Use only enough pull on the tape to conform it properly to irregular surfaces of the pipe or fitting.
7. When the end of the wrap is reached, release all pull on the tape, cut the tape and if desired prime the end with Protecto Wrap 1170 primer. Smooth the end into place over the previous lap.
8. Lightly press overlap seems to insure a firm contact and bond.
9. When using a cigarette wrap for Protecto Wrap 200 & 200GT tape, follow all instructions above and brush the tack side of the tape lightly with Protecto Wrap 1170 primer where it forms a seam, smoothing it down with your hand.
10. When wrapping pipe to be jacked or pushed under crossings, always start and end joint with tape at a 90° angle to the pipe and use a minimum of primer at the overlap seam.
