INSTRUCTIONS
ThistleWrap is a specially treated woven glass fabric impregnated with
a polyurethane resin, which is activated by immersion in water. ThistleWrap
is ideal for pipe repairs to low pressure systems. As a general guide,
a repair build up to a thickness of approximately 12 mm (½”) over the
leak can withstand a maximum service pressure of 10 bar (150 psi). Higher
pressures, up to 50 bar (725 psi), can be achieved by first applying
over the leak, a ‘plug’ of ThistleBond twist-stick grade metal-filled
epoxy putty (TRK No. 19060)
INSTRUCTIONS FOR USE
- Prepare pipe surface around repair area by wire brushing loose rust,
paint etc. or if smooth, abrade with coarse emery cloth or similar.
- Wearing protective gloves, remove roll from the foil bag and immerse
in water (preferably fresh) for approx. 10 to 20 seconds, squeezing
two or three time.
- Remove roll from water and wrap quickly and tightly as follows:
Centre tape over leak site, wrap from bottom of roll, putting firmly
throughout application. After several windings of tape, which should
extend 1.5 to 2 pipe diameters each side of the hole, resin foam will
come through the tape which is desirable and aided by pulling tightly.
The tape should be wound on with a half width of tape overlap keeping
it flat and even, maintaining tightness. Apply one or more rolls,
as the repair dictates. Firmly press and smooth end of rolls into
wrap in the direction of application. Wet gloves in water, smooth
and firmly press the wet resin back into the wrap.
Keep hands moving quickly and wet gloves frequently to avoid sticking.
As the repair cures it will warm up very slightly, which is normal.
- Continue rapid hand movement pressing and polishing resin in motions
around and parallel to the pipe. Continue process until resins are
no longer tacky. The repair should now have a smooth, hard surface
and an enamel like appearance with no fiberglass substrate showing
through the resins.
Notes:
- If a thicker application is needed, spend a little less time finishing
the first roll and immediately begin the application of the next.
Finish the final roll as if a single roll application.
- If the hole in the damaged pipe is larger than 3mm, you can use
Thistlebond TRK19060 Metal Repair Stick to first “plug the hole”.
After curing you can then processed as in step 1.
- If the fluid in the pipe can not be turned off – you can use the
TRK19060 Metal Repair Stick to first plug the hole and then proceed
to wrap as above.

HEALTH & SAFETY
As long as normal good practices are observed, ThistleWrap can be safely
