Fault
Crack does not fill
with resin.
Ray-like cracks are not
filled with resin.
Resin does not
harden.
Repair point becomes
cloudy.
Fracture appears
again.
Repair resin spilt on
the vehicle.
Possible cause
Pressure too high.
Suction holder incorrectly
positioned.
Injector applied too tightly.
Resin does not cover fracture.
Fracture cover with glass
splinters, dirt or wax.
Pressure holding time too
short.
Repair point not covered with
hardening film.
Curing time too short.
Repair resin contaminated.
Moisture.
Contamination in the fracture.
Repair resin contaminated.
Hardening film removed too
early.
Windscreen too warm.
Moisture in the fracture.
Insufficient repair resin used.
Remedy
Gradually increase pressure to 2.4 bar.
CAUTION: Pressures above 2.4 bar can
damage the film, resulting in shadowing at the
repair point.
Position the opening of the injector exactly over
the fracture.
Loosen injector by ¼ turn.
Add repair resin and draw the vacuum for two
minutes.
Loosen the brass nut of the suction holder and
push the injector off the fracture. Remove resi-
dues in the fracture using a scraper blade.
Maintain the pressure for a longer period.
Cover repair point with hardening film.
Prolong the curing time.
Thoroughly clean the injector before changing
repair resins (repair resins must not be mixed).
Do not use contaminated repair resins.
Prolong the vacuum phase until all moisture
has been removed from the repair point.
Remove all wax, soap, oil, Rain-X, etc. from the
fracture.
Use only pure repair resin.
Leave the hardening film on the repair point
longer.
Allow windscreen to cool down.
Dry fracture thoroughly.
Completely cover the fracture with repair resin
(allowing for the shrinkage during setting).
Do not try to wipe off.
Harden the repair resin using the UV lamp and
then pull off the paint surface.
