Ways to Repair a Cracked Windshield

Why we need to repair the cracked windshield?

The damage of auto glass is mainly caused by the small stones carried or left by the front and side vehicles hitting the front windshield. If the force is not enough to make it break but only cracks, the glued layer of glass in the middle will split into a long shape or a round shape due to the entering air and atmospheric pressure. If it is not handled in time, windshield crack will increase, as the glass expands and contracts with heat. If you continue to drive, the crack area will become larger, which will affect the structural integrity of your car and driving safety. Your view will be affected as well. Therefore, once the car windshields cracks, it is recommended that you must go to a professional auto glass repair shop to get it professionally repaired, stopping cracks from spreading.

The process of windshield repair

Step 1: Before repairing, professional need to clean up the damaged parts and remove the glass ballast or other pollutants. The best condition is that there is no dust, water, and impurities in the cracked area. In some cases, it is necessary to expand the cracks, for the repair glue to enter the inside of the crack more easily.

Step 2: Professional uses an electric drill to drill a hole in the center of the crack. The purpose of drilling is also to make it easier for the repair glue to enter the cracks.

Step 3: Professional uses the suction cup to fix the plastic injection head above the centre of the crack and presses it tightly.

Step 4: Technician injects the repair glue and do pressurize treatment. Depending on the brand and type of the repair glue, the amount of dripping varies, and it is often necessary to drip 4-5 drops. In addition, it is often necessary to use a vacuum method to extract the air in the crack at this step to facilitate the entry of glue.

Step 5: Technician has the pressure injection of repair glue; this step usually takes 20-30 minutes. The next step can be performed only after the repair glue has completely entered the crack.

Step 6: Professional repairs the vertical cracks, usually by direct dripping. Due to the principle of liquid expansion, the repair glue needs to drip from bottom to top. When dripping, the film should be smoothed in time to prevent air from entering the cracks.

Step 7: Worker uses UV or direct sunlight to heat the crack for 5-10 minutes.

Step 8: Worker need to scrape off the residual glue with a razor blade, and finally treat the glass surface with a polishing agent to complete the work.

A small round mark or crack is usually left in the repaired crack, which can only be seen at a special angle. We need to know that due to impact conditions, it is almost impossible to glass repair without traces.

We should understand that not all windshield chips can be repaired. The crack repair is better used in the case of small damage. Once the glass separates or breaks into pieces, which affects the driver’s main viewing area, it is not recommended to be chip repaired. You may consider the windshield replacement.

Precautions after car windshield repair

1. It is best to repair within 3 days
2. Crack area should not touch water or dust after damage. Therefore, it is recommended to seal the damaged area. If moisture enters, the water removal step will be added, which will increase the repair time.
3. If it is damaged and exposed to water, it is recommended to dry it naturally for about 10 hours before repairing, otherwise the repair will be like unrepaired after the water dries out for a while. After the repair, the car glass will not continue to crack or explode, and there is no problem in normal use. The entire repair process takes about 30-50 minutes.

The maintenance of windshield

In the usual glass maintenance process, the appropriate glass cleaner should be selected according to the specific conditions of the season and weather. When the surface of the windshield is found to be blurred, it will be brighter if it is cleaned with suitable glass cleaner. If you find the problem of chaotic light reflection on the glass at night, you can also wipe it with glass cleaner.

Some car owners think that clean the windshield is just cleaning and decontamination, so they use washing powder or detergent instead of glass cleaner. Ordinary detergents will continue to corrode the rubber tube and accelerate the hardening of the wiper strip. When the hardened rubber strips scratch the windshield, it will make the surface of the windshield to be shaved and scratched. The cost of replacing rubber strips will be much more expensive than the price of glass cleaner.

Although ordinary clean water is very clean, there are many chemical residues in it. Long-term use will increase the friction of the mirror surface, which will easily lead to slight scratches on the mirror surface when the blade is working.
