How To Fix Cracked Glass

Cracked glass can be an eyesore and a safety hazard. Whether it’s a window, a mirror or a phone screen, a crack can quickly become a bigger problem if not addressed. In this article, we will go through the steps on how to fix cracked glass and save yourself the trouble of having to replace the whole thing.

Assess the Damage

Before you start fixing the crack, you need to assess the damage. Is it just a small crack or a larger one? If it’s a small crack, you may be able to fix it yourself. However, if it’s a larger one, you may need to seek professional help.

Types of Cracks

There are different types of cracks that can occur on glass surfaces. Some of the most common ones include:

  • Single crack
  • Spider web crack
  • Edge crack
  • Star crack

DIY Fixes for Small Cracks

If the crack is small, you can try fixing it yourself. Here are some DIY fixes that you can try:

Super Glue

Apply a small amount of super glue to the crack and hold the edges together until it dries. This will prevent the crack from spreading and make it less noticeable.

Nail Polish

Apply a clear nail polish over the crack. This will fill in the crack and prevent it from getting worse.

Baking Soda and Super Glue

Mix baking soda and super glue together to make a paste. Apply the paste to the crack and let it dry. Sand the surface until it’s smooth and the crack is no longer visible.

Professional Help for Larger Cracks

If the crack is too large to fix yourself, you may need to seek professional help. Here are some options:


If the glass is severely damaged, you may need to replace it. This is the most expensive option, but it ensures that the crack is completely gone.

Resin Injection

Resin injection is a process where a special resin is injected into the crack to fill it in. This is a cheaper option than replacement and can be done quickly.

Window Film

If the crack is on a window, you can apply a window film to cover it up. This won’t fix the crack, but it will make it less noticeable.


Can I fix a cracked phone screen myself?

Will a cracked windshield pass inspection?

It depends on the severity of the crack. If it’s a small crack, it may still pass inspection. However, if it’s a larger one, you may need to get it fixed before it can pass.

Can I still use a cracked mirror?

Yes, you can still use a cracked mirror. However, it’s not recommended as it can be a safety hazard.


In conclusion, fixing cracked glass can be done yourself if it’s a small crack. However, if it’s a larger one, you may need to seek professional help. It’s important to assess the damage and choose the right option for your situation. With these tips, you can fix cracked glass and make it look like new again.
