Why Does Your Car Windshield Crack From The Inside?

Have you ever gone to get into your car and found that the windshield has developed a crack overnight? While it may seem like magic, there’s a scientific explanation for why this happens.

It all has to do with the rubber sealant that holds the windshield in place. Over time, this sealant dries out and becomes brittle. So when the temperature outside fluctuates – such as when you turn on the A/C on a hot day or the defroster on a cold day – it causes the windshield to expand and contract.

Eventually, this repeated stress leads to a crack forming in the glass. While there’s not much you can do to prevent this, it’s vital to have any cracks repaired promptly. Otherwise, they will only continue to grow and could eventually cause the entire windshield to collapse.

How Long Can You Have A Crack In Your Windshield?

If it’s cracked from one side, from the outside only, it’s not a problem to solve immediately. You can wait until it’s more convenient for you to take care of it.

But, if the windshield is already cracked from both sides, you need to act now. Windshields that are cracked from both the inside and outside need to be replaced as soon as possible.

How to fix a cracked windshield?

It’s not as difficult as it may seem. With a few simple steps, you can fix a cracked windshield yourself.

First, clean the area around the crack with a glass cleaner and a lint-free cloth. Then, use a razor blade to remove any loose pieces of glass.

Next, apply a thin layer of resin to the crack. You can buy resin at any auto parts store. Then, use a UV light to cure the resin.

Finally, apply a clear sealant to the area to prevent the crack from spreading.

You can quickly fix a cracked windshield yourself if you follow these steps. But this is a temporary fix. If the crack is severe, you should have it professionally repaired. Please don’t wait too long to fix the problem, as it will only get worse over time.

Can A Crack On The Inside Of A Windshield Be Repaired?

Most cracks can be fixed with a special resin. The resin is injected into the crack and then cured with ultraviolet light. This process fills the crack and prevents it from spreading.

While it will not completely restore the windshield’s strength, it can significantly improve its stability and prevent further damage.

How Do I Stop My Windshield From Cracking Further?

If you have a crack in your windshield, it is essential to take action to prevent the damage from spreading.

One way to do this is to apply a layer of clear nail polish to the crack. This will help seal the crack and prevent dirt and moisture.

It would also help avoid sudden temperature changes, such as turning on the heater full blast when the car is cold. This can cause the glass to expand and contract, making the crack worse.

By taking these simple steps, you can help to prevent your windshield from further damage.
