Why is a Cracked Windshield Dangerous?

A cracked windshield can be a major safety hazard. Windshields are designed to provide structural support to your vehicle and protect you from the elements.

When a windshield is cracked, it weakens the structural integrity of the car, making it more vulnerable to being crushed in a crash or other impact. Furthermore, a cracked windshield can impair the driver’s vision, making it difficult to see the road and other drivers.

Finally, a cracked windshield can cause the driver to be more exposed to the elements and can easily shatter in an accident, potentially causing serious injury. 

Prevent Windshield Crack From Spreading

Windshield cracks can quickly spread from a minor chip to a major problem. This can be dangerous and costly if you have to replace the entire windshield. Fortunately, there are a few things you can do to prevent the crack from getting worse. 

Seal the Windshield Crack

Fortunately, there are a few simple steps you can take to seal the crack and help stop it from getting worse. 

First, clean the area around the crack with a damp cloth to remove any dirt and debris. This will help ensure a secure seal when you apply the repaired product. Then, use a razor blade to scrape away any loose pieces of glass that may have broken away from the crack.

Next, apply a sealant specifically designed for windshield repair. There are many products available on the market for this purpose. You can find them at most auto parts stores. Apply the sealant according to the instructions on the package. 


Once the sealant has dried, you can use clear silicone caulk to cover the windshield crack. This will provide an extra layer of protection and help keep moisture from entering the crack. Allow the silicone caulk to dry completely before driving the vehicle. 


Try a DIY Windshield Repair Kit

A DIY windshield repair kit is designed to fill the crack in your windshield and stop it from spreading. The kit contains a resin that is injected into the crack. This resin will harden and form a seal that will keep the crack from spreading. The kit also contains a curing strip that is placed on the windshield in order to hold the resin in place.

To use the DIY windshield repair kit, first, clean the windshield with glass cleaner. Then, apply the resin to the crack using the syringe provided in the kit. Once the resin is in place, secure the curing strip to the windshield. The curing strip should be held in place for at least 30 minutes. After this time, the windshield repair is complete.

Avoid Exposing Your Windshield to Drastic Temperatures

Parking in the shade can help protect your windshield from the sun’s rays and keep the temperature more consistent. This can help avoid thermal shock, which can cause a crack to spread.

Drive Your Car Cautiously

Driving your car cautiously can help to prevent a windshield crack from spreading and becoming even more costly to repair. Avoid sudden and abrupt stops, turns, and accelerations, as this can cause the windshield to flex and cause further damage.
