Temporary Solutions for Stopping Windshield Cracks From Spreading

For a quick fix to a tiny crack, you can use super glue, nail polish or tape to stop the crack from spreading.

Using Superglue

Superglue can act like a quick fix for your windshield crack. Before you start, make sure the glass is clean. Use auto glass cleaner and paper towels to wipe it down. Then, take the super glue and carefully put it on the crack.

This helps hold the crack together so it doesn’t get bigger. It makes a strong bond that stops the crack from growing when there’s stress or movement.

Keep in mind, super glue is just a temporary solution to keep things under control until you can get professional help. It won’t last forever but it’s good for making sure things don’t get worse right away.

Always handle superglue with care and use only a small amount on the cracked area to avoid any mess or further damage to your car windshield.

Clear Acrylic Nail Polish

Clear nail polish can be a quick and convenient way to temporarily stop a windshield crack from spreading. This common household item, when applied over the damaged area, can help prevent the crack from getting longer before you have the chance to seek a permanent solution.

It’s important to remember that while clear nail polish can be effective in halting the progression of cracks, it is only a temporary fix until you can pursue more lasting repair options like windshield repair kits or professional auto glass repair services.

Applying Tape

Tape, particularly clear tape, is a simple but effective temporary fix for preventing windshield cracks from spreading. By carefully applying the tape over the crack, you can stop debris and moisture from seeping into the crack and causing more damage.

This affordable solution acts as a barrier that helps to maintain the integrity of the windshield until a permanent repair can be made.

Permanent Solutions for Stopping Windshield Cracks

Windshield repair kits, mobile auto glass repair, and replacement are permanent solutions for stopping windshield cracks.

Windshield Repair Kits

Windshield repair kits are a practical and cost-effective solution for preventing the spread of cracks and chips in your windshield. These kits work by filling in the damaged area with a special resin, which helps to restore the structural integrity of the glass.

It is essential to choose a windshield repair kit that matches the size of the crack or chip, ensuring an effective and lasting repair. Some advanced repair kits can even fix long cracks and chips, offering a more robust solution than opting for a new windshield.

Additionally, chemical treatment provided by these kits replaces lost grains of glass, providing a durable and stronger fix.

Mobile Auto Glass Repair

When addressing a windshield crack, mobile auto glass repair services offer a practical and convenient solution for repairing the damaged windshield.

Truth is, mobile auto glass repair offers the advantage of getting their windshield fixed without having to drive to a specific location. This service ensures that the crack is dealt with using professional repair techniques, preventing further damage and ensuring driver safety on the road.


When the crack in your windshield becomes too large to repair, it’s time for a replacement. With numerous windshield replacement providers available, it’s important you choose a windshield that matches the features and specifications of your original one.

This helps maintain the integrity and functionality of your vehicle.

Understanding Windshield Cracks

Windshield cracks can be caused by a variety of factors, including flying debris, temperature changes, and structural damage. There are different types of windshield cracks, such as edge cracks, bullseye cracks, and floater cracks.

Understanding what causes these cracks and the different types can help in finding the right solution to stop them from spreading.

Causes of Windshield Cracks

Different things can lead to cracks in your car’s windshield. Sometimes the glass is not put in right, and this can make it crack from stress. Other times, a big change in temperature makes the glass expand or shrink too fast, causing it to break.

Things hitting your windshield while you drive can also cause damage. Stones flying up from gravel roads or something falling on the glass are common ways cracks start.

Even after a small crack happens, it might get worse. Weather that changes a lot can make small cracks grow into big ones. If you’re driving and debris hits these weak spots, they could spread out or split apart even more.

It’s important to know that once there is any damage, being careful with how you handle your car is key to keeping that little chip from turning into a big problem.

Types of Windshield Cracks

Cracks in a windshield can come from many things like rocks or changes in temperature. They can get bigger over time if you don’t fix them.

  • Crack Chip: This is a small crack that can be around the size of a quarter. It usually comes from a rock hitting the window.
  • Stress Crack: This type of crack happens without anything hitting the glass. It can come from a big change in temperature, like when it gets very hot or very cold fast.
  • Bullseye Crack: This looks like a target or bullseye. Something round hits the windshield and makes a circle with lines coming out from the center.
  • Hairline Crack: These are thin lines that can be hard to see. They might seem small but can spread quickly across your windshield.
  • Star Break: This kind has little lines coming out a small hole from a point, looking like a star. Just like with bullseye cracks, something hitting the window causes this shape.

Preventing Windshield Cracks from Spreading

Avoiding extreme temperatures, driving cautiously, and parking in the shade can help prevent windshield cracks from spreading. Find out more about how to protect your windshield by reading the full blog post!

Avoiding Extreme Temperatures

Extreme temperatures can cause windshield cracks to spread. Cold weather can make the glass contract, while heat causes it to expand quickly. This expanding and contracting can force the crack to grow longer and wider.

Therefore, parking in shaded areas and avoiding sudden temperature changes are essential for preventing windshield cracks from spreading further.

Driving Cautiously to Help Stop a Windshield Crack From Spreading

The best way to prevent windshield cracks from spreading, driving cautiously is key. This means avoiding bumpy roads and speed bumps whenever possible, as the jolts from these can cause the crack to spread.

Additionally, when shutting car doors, do so gently to avoid putting pressure on the already cracked windshield.

Being mindful of your driving habits and taking extra care when navigating rough terrain or closing doors can significantly reduce the risk of further spreading a windshield crack.

Parking in Shade

Parking your car in the shade can help prevent windshield cracks from spreading. This is because direct sunlight, extreme temperatures, snow, and rain can all contribute to the growth of existing cracks.

By choosing a shaded spot, you can maintain moderate heat levels that are more favorable for preventing cracks from worsening on your windshield. Additionally, parking in shade provides a stable environment for your vehicle, reducing the risk of vibrations caused by driving which could lead to small chips or cracks expanding quickly.

By avoiding direct sunlight and opting for shaded parking areas whenever possible, you can play an active role in minimizing the risk of windshield damage spreading further.

Closing Thoughts

Understanding how to stop windshield crack from spreading is essential for ensuring the safety and longevity of your vehicle’s windshield.

Temporary repairs like using superglue or clear nail polish can help stop windshield cracks from spreading. But it’s important to seek a professional windshield repair shop quickly to prevent further damage.
