How to use

SURFACE PREPARATION

Remove any dirt, oil, grease, rust by suitable methods.
Remove any metal burrs or weld spatter. The minimum
requirement for surface preparation of pipe/steel surface
is by mechanical/power wire brushing to remove any
rust scales. Grit blasting can also be done in heavily
contaminated areas

PRIMER

Bitutape Primer* (solvent based bitumen primer) shall be
used for priming the steel surface prior to the application
of the wrapping tape. Stir the contents of the primer for
1-2 minutes to remove any sediment. Apply the primer
at the rate of 4-6m2/L with a brush or roller evenly to
ensure complete sealing of all small undulations and
imperfections, particularly around weld beats. Reseal the
containers when not in use. 

WRAPPING

Application instructions are for guideline only and are
subjected to alterations for specific project requirements.
Wrapping should not commence until the primed surface
has become touch dry. Apply strips of tape 100mm wide
along the weld beads and press firmly. Peel back 150 to
300 mm of the release film and apply the tape, adhesive side, to the pipe. The angle of the tape must be such as
to produce the specified overlap. Apply only sufficient
tension to ensure good conformation avoiding air pockets
and bridging. Ensure end lap area of at least 150 mm
when splicing the tapes. Backfill with care. Use of an
Bitustick R protection membrane is recommended to
prevent any damage from backfilling. Avoid use of rocky or
agglomerated backfill.
