How to Stop a Windshield Crack From Spreading?
A tiny chip or crack in your windshield might not seem like a big deal at first, but it can quickly turn into a major problem if left unchecked. It may seem to be minor, and a few of us may not care much. However, it is important to stop the cracked windshield from spreading to its entire length. In this blog, we will discuss how to stop a windshield crack from spreading.
Why Keeping Your Windshield Crack-Free Is Important?
Rather than being just a piece of glass, the windshield protects you from dust, insects, UV light and wind while providing clear visibility for safe driving. A windshield is an integral part of your car and plays a role in its structural integrity. It helps airbags deploy correctly and safeguards the roof, just in case you have a collision of any sort. A cracked windshield can become a safety hazard if you are not careful. A major crack can impair your vision and lead to a loss of control while driving.
Common Causes of Windshield Cracks
Understanding the possible causes of windshield cracks can help you prevent your windshield from cracking. Some of the reasons that cause windshield cracks are:
Road Debris and Stones: This may be a common cause on a highway. If you are behind large vehicles, you may run the risk of flying stones. In fact, even a tiny pebble travelling at high speed can cause a significant crack in your windshield.
Temperature Changes: Sudden changes in the temperature can also crack your windshield. The impact of temperature on glass cracks may depend on the type of glass used, but it can significantly affect the crack and spread it further. Glass expands and contracts with temperature changes, and extreme fluctuations can lead to windshield cracks.

Improper Installation: If you have your windshield, any improper installation can result in damage. It can shake, rattle or be misaligned. In any of these cases, the glass would be more vulnerable to cracks.
Structural Stress: An older vehicle may suffer from structural stress. In fact, a vehicle that has gone through rough handling may also develop cracks.
How to Protect the Windshield From Further Damage After Breakage?
Well, you have a crack now. Can you prevent it from further damage? Yes, but we recommend checking out the steps to repair a cracked windshield as early as possible.
Here are some tips to prevent further damage:
- Avoid bumpy or rough roads. They can create vibrations and thus damage the glass further. Drive gently and stick to smooth roads until the crack is repaired.
- Do not drive in the rain. Water can seep into the crack and weaken the adhesive layer. Seal the crack temporarily if you need to drive.
- Park your vehicle under a shelter. Exposure to the external elements can cause further damage. Be it scorching sun or freezing cold, always park your vehicle in the shelter.
Temporary Fixes to Prevent the Crack from Spreading
It's best to repair car glass damage as soon as possible if you have a cracked windshield. However, until you go for the permanent fix, you can check out a few temporary fixes to help avoid the crack from spreading.
Apply nail polish or glue: This can appear to be too simple. But, it is seen working in most cases. Apply a thin layer of nail polish or glue on the crack. Let it dry in a shaded place for a while.
Use a windshield repair kit: Small cracks and chips in the glass can be fixed with a windshield repair kit. You can find it in most of the auto repair shops. It can help you achieve a quick fix for a windshield crack at home.
Use a small, sharp object to clear debris: If you are looking to apply any sort of sealant, make sure to remove the debris stuck in the crack using a razor blade or pin. This will ensure a cleaner repair.
Apply tape to the crack: A clear tape can help you seal the crack easily. This can help keep the moisture and dirt at bay. In fact, it will provide you with enough time to get professional assistance.
Long-Term Solutions for Windshield Damage
We would never recommend opting for the temporary fixes and being content. The fixes outlined above are just for the sake of getting enough time for professional and permanent solutions. The DIY fixes can be helpful, but they won't last forever. Here are a few long-term solutions that will help :
Get Professional Windshield Repair: If the crack is very small, professionals can inject a resin into it and seal the crack completely. In fact, this sort of repair is affordable, and is covered by insurance in many cases.
Windshield Replacement: For large cracks windshield replacement is the right option. A large crack may hinder the line of sight for the driver and jeopardise the safety. Such a situation may need windshield replacement.
