Crack Cleaning

To prepare repair windshield crack, we need to clean it and clear all dirt, moisture and excess glass and then we make 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.

Resign Filling

Auto Glass Masters windshield 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. Before 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 windshield glass.

Curing

The resin used to repair windshield, 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.

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 windshield. Clean the area afterward with glass cleaner.
