Car windscreen repair procedure 1. Don’t ignore a small windscreen crack caused by a stone or minor impact. This can be a mistake, since small cracks can
spread on a car windscreen, especially in very cold weather. This is because manufacturers make toughened auto windscreen
glass under intense pressure. The glass has very high density and this causes cracks to spread progressively. In other words, even
small car windscreen cracks and chips can be a serious matter
2. Decide between repair and replacement. First our technician inspect your vehicle windscreen damage for stability and to
determine either your car windscreen need repair or replacement.
3. Preparation. To prepare the windscreen crack for repair, it first needs to be cleaned and cleared of dirt and moisture and excess
glass and then made into a bull’s eye crack, if it’s not already one. This is done to keep individual cracks and prevent it from further
widening and spreading. To prevent damage, a cover or protective drape is applied to your vehicle
4. Resin injection: New auto windscreen chip repair method include the revolutionary PRISM (pre-resin injection suspension
method) technology and various techniques that involve injecting resins into the cracks with or without vacuum.
After loading the specified amount of resin into the injector, the bridge is positioned so that the injector is directly above the crack.
Then the bridge is secured in place and proceeded with operating the injector to force resin into the crack. Alternately the pressure
and vacuum controls of the injector is applied to suck out air from the crack and force resin in. After the crack has been completely
filled, the bridge will be removed. The resin has the similar optical properties to windscreen glass.
5. Curing: The resin used to repair windscreen, is an anaerobic substance which means that, instead of air, it requires ultraviolet or
UV light to dry and harden completely. The chipped area is sealed and the resin is cured by Ultra-Violet Light.
6. Resurfacing and Finishing: After the filler resin has finished curing, a sufficient amount of resurfacing resin will be applied directly
to the repaired crack. This will be covered with a cellophane patch (usually supplied with the repair kit) and be cured using a UV
lamp or direct sunlight. After the resurfacing resin has finished curing, the excess will be scraped off with a blade to level it out with
the rest of your car windscreen. Clean the area afterward with glass cleaner.
7. Once the windscreen chip and crack area is repaired, the damaged area will not disappear completely. There will usually be a
small mark in the damaged area and it resembles a small dried rain drop.
8. The windscreen will be restored back to full strength and the chip will no longer be vulnerable to spreading. A windscreen
repair usually takes 30 minutes to complete.

Before calling us, please keep your car windscreen dry as much as you can. Dry is really essential. We don’t want any water
trapped in the repair.
But don’t worry if it was not possible, we do it by using a hair dryer if your car windscreen is wet. If the surface is dirty, don’t use any
detergents or window cleaner. Lighter fluid or acetone can help dry and clean the surface.
In the next stage, the adhesive patch is burnished to a perfectly clean windscreen and adapter.
The image below also illustrates the schematic windscreen repair in details. Alternating cycles of vacuum and pressure will push
adhesive into the chip, and evacuate air from the bottom of the chip.
