How To Fix A Star Crack In Windshield?

A star-shaped crack on your car’s windshield is definitely a point of concern that requires immediate attention. If you continue to delay getting the crack fixed, it will only worsen over time and even end up being a safety hazard! Here’s what you have to do to fix star cracks in windshield:

• Get a windshield repair kit. 
• Clean the damaged area. 
• Apply the adhesive from the kit. 
• Let the adhesive dry.
• Remove excess adhesive with a razor blade.

Let’s shed more light on this process in this blog.

What Are Star Cracks In Windshield?

A windshield crack can be of various types - bullseye, hairline, halfmoon, and whatnot. But for the sake of this blog, we will narrow the topic down to star cracks. Just as the name suggests, star cracks are the ones that vaguely resemble the shape of a star. 

Why Do Star Cracks Form On Windshields?

This happens when a rock or some other hard object hits the windshield, and the crack that forms spreads out from a focal point. It can be challenging to repair a star crack because the damage affects the outer layer and penetrates the inner layer of the glass, too. That is why it is best to leave these cracks to professional windshield repair technicians to fix. If you're looking to fix a hairline crack in windshield, it's important to address it promptly before it spreads and becomes more difficult to repair."

Steps to Repair a Star Crack In Windshield

To repair a star crack, windshield repair specialists first rid the region in question of dust and debris. Then, a specific resin is used to fill the cracks. After this, the resin is bonded with the glass through ultraviolet radiation, restoring its original glory. Let’s have a look at the steps to repair a star crack on the windshield.

Sep 1. Get A Windshield Repair Kit

DIY enthusiasts should get a windshield repair kit before they attempt to repair the star crack. The kit typically consists of repair resin, a razor blade, an adhesive patch, a pedestal, and syringe curing strips.

Step 2. Clean The Damaged Area

Thoroughly clean the damaged area to remove any trapped moisture or dust. You can also use a glass cleaner.

Step 3. Apply the Adhesive Patch From The Kit

Place the adhesive patch on top of the crack. Ensure the crack is not bigger than the cut-out in the adhesive patch!

Step 4. Fill The Crack With Epoxy Resin

Follow these instructions to fill the crack properly:

• Mix your repair resin and pour it into the pedestal till the brim.
• Then, firmly attach a compressed syringe to it. 
• Hold the pedestal firmly as you slowly pull the syringe plunger to fill the syringe.
• Next, force the syringe plunger down and fill the crack with resin. 

Step 5. Place The Curing Strips On The Filled Crack

Once the resin settles, remove the adhesive patch. Then, put two drops of resin on the filled crack and wrap it with the curing strips. Gently hold the curing strip as you use a razor to draw out the air bubbles. 

Step 6. Use A Razor To Scrape Off Excess Resin

Next, use the razor blade to remove the curing strip. Twist it as you remove it so that you do not accidentally pull the filled resin. Once the strip comes off, use the blade to scrape in the opposite direction to remove any remaining resin. 

If you have followed the steps and made it here, congratulations! The star crack on your windshield is fixed for good.
