How easy is it to crack a windshield?Windshields are made of glass and plastic components, so naturally, they can only withstand so much pressure. Even though a surprise crack in your windshield can be frustrating, you should know that windshield repairs are not difficult and are often covered by your car insurance.
What household items can you use to fix a cracked windshield?
Grab Clear Nail Polish
If your windshield has a small chip or crack in it, you might be able to quickly fix it with clear nail polish. Crazy right? By using this household item you're already saving crazy amounts of money. All you need is a bottle of this stuff and a nail polish brush and you are good to go.
Does Super Glue work on cracked windshield?
Use Super Glue or Nail Polish as a Temporary Fix
These household products should only be used to stop a windshield crack from spreading if the crack is small. Superglue: Very gently apply the glue in an even layer over the crack. Wait for it to completely dry before using your car.
What can cause a windshield crack to spread?
5 Reasons Windshield Damage Spreads
- Moisture. One of the top causes of spreading windshield damage is rain, snow and ice.
- A Bumpy Ride. If you drive over a pothole, slam on your brakes or shut your car door a little too firmly, you could make your windshield damage worse.
- The Hot Sun.
- Extreme Cold.
Another thing to keep in mind is to avoid pressing on a broken windshield from the interior of the car. The entire windshield's concave shape can severely weaken the structure of the windshield when it is cracked, and pushing on it can only make it worse.
It typically takes 20,000 to 24,000 pounds per square inch (psi) of force or pressure to break a car window.
The design pressure for a basic residential window is 15 pounds per square feet. Under most conditions, the window can hold up to 15 pounds of pressure for every square foot of its surface before it breaks.
Use Super Glue or Nail Polish as a Temporary Fix
Superglue: Very gently apply the glue in an even layer over the crack. Wait for it to completely dry before using your car. Clear Nail Polish: Clear nail polish can work in a similar way to superglue.
Spread Nail Polish on the Crack
Like superglue, clear nail polish can serve as a temporary fix to stop a windshield crack from spreading while you're on the go. And, like superglue, nail polish can be highly difficult to remove once it's been applied.
UrethaneUrethane – The Windshield Glue
The glue, or adhesive, used for windshield installations is called urethane . It is a deep black type of glue that gets onto everything it touches.
There are a couple of methods auto owners can try to stop or slow the spread of a windshield crack.

- Use a Windshield Repair Kit.
- Avoid Sudden Temperature Changes.
- Schedule Windshield Repair or Replacement.
Cracked windshields not only reduce the aesthetic appeal of your vehicle, but also reduce visibility on roads while you're driving. These cracks usually spread over time—if not tended to. This makes your car unsafe to drive, especially if the chip is more than 12 inches long.
Can your windshield crack from cold? It's possible. Cold temperatures cause contraction—even in glass—and if it's cracked or chipped the added pressure can cause further damage. The sun can also make the crack or chip worse, as it can increase the temperature of the windshield, causing the crack or chip to expand.
Changes in Temperature
When this happens, your windshield's structure tends to shift, thus weakening the corner of each crack or chip. In one day, these cracks will start spreading on a microscopic level. Within a few days, you will see marked differences in the crack with the naked eye.
It is impossible to break a double glazed window with your bare fist. If it were possible, someone would have done it by now. The problem with your bare fist and a window is that both your fist and the window will move under impact, reducing the force of your blow. Your fist squashes, and the window bends outwards.
Tempered glass can withstand a pressure of 24,000 psi without breaking. A piece that is 11 by 16 inches with a thickness of 3/16 inch can support about 240 pounds.
Through the annealing process of hardening tempered glass, the force required to break the window is much more than breaking a normal pane. Depending on the manufacturer, the force required to break tempered glass ranges from 20,000 to 24,000 PSI (or pounds per square inch).
We're here to tell you that glass isn't really unbreakable, but there are two popular window materials that are marketed as “unbreakable” that help keep your home and family safe from broken shards and break-ins.
Apply Superglue or Clear Nail Polish
Then, as a low-fidelity solution, apply clear nail polish or superglue to the chip. Allow the polish or glue to dry, and then place a piece of clear packing tape over the area to help keep dirt out until you can have the chip repaired.
