Types of Windshield Cracks

Types of Windshield Cracks

So, how many types of windshield cracks are there? There are different types based on what has hit your windscreen. Sometimes it’s just a chip, while at other times, you might have to deal with cracks as well.

There are so many types of these cracks. There are stars, bulls-eyes, chips, cracks, and different combinations as well. Each of them needs a slightly different technique to fix. Let’s have a brief look at all these types one by one.


There are three different varieties of these cracks. There are stress cracks that can occur not from direct impact but repeated impacts over time. These can also occur with extreme cold or heat.

There are edge cracks that can extend to the center of the glass. And then, there are floater cracks that can be around a couple of inches in size from the windshield edge and extend with extreme cold or heat.


These occur due to different debris impacts on the windshields and occur with a small divot. You need to repair these chips as soon as possible, or they can turn into cracks. 


These are bullseye-shaped chips, and when they occur, the windscreen glass looks like a crater, and there are concentric circles coming out of the central divot.


When a chip has multiple tiny fissures coming out of the center in a starry pattern, it is called a star crack. These cracks are easier to repair with glass fillers.


Combo cracks are usually a mix of different cracks. They occur after multiple impacts, and a replacement becomes mandatory for the integrity of the glass. Some of them are pretty large ones as well. They can span the entire windshield, so you need to replace them immediately.

How to Fix a Crack in Your Windshield – Step by Step

How to Fix a Crack in Your Windshield

Thinking about do it yourself windshield repair? This section will list some necessary steps to fix that annoying crack in your windshield. But first, you need to address the issue of how big a crack is to repair on your own.

The rule of thumb for you to follow is that the cracks larger than three inches and the larger chips than a quarter-inch should be fixed with a do it yourself windshield repair technique.

Here are some practical steps that you need to take to get the job done.

●     Applying the adhesive

You need to begin by peeling off that paper backing on your adhesive patch for exposing a side of the adhesive. Ensure the chip is no bigger than that circular cutout present in the middle of the patch. Now center the patch right over the chip and apply it for cleaning.

But make sure the dry side is facing outside of the windshield glass. Peel off the other side and apply it to the pedestal. The pedestal is a molded plastic piece featuring a tube that is angling upward. Then line up all the tabs so you can remove them easily.

●     Mixing the resin

Mix your resin and pour the liquid into that pedestal. You need to fill it to the top. Make sure to compress the syringe down and insert it firmly right into the pedestal.

With one hand, hold the pedestal and pull up the syringe plunger with your other hand. You don’t need to worry because it won’t draw up your resin. You can continue drawing up your syringe till you reach the end of its length. Some syringes also feature a clip for stopping you from accidentally removing the syringe.

Moreover, drawing up the plunger will create a vacuum that will take the air bubbles out of the syringe and away from the chip you are working on. You will also notice the same as the bubbles are leaving the chip.

Some kits can only take a couple of minutes, while others can take up to 10 minutes. But make sure all the bubbles are gone and don’t proceed to the next step.

●     Forcing the resin into the chip

The next step is to hold the pedestal with one hand as you remove the syringe with your other hand from the pedestal. It’s time to insert the syringe again and slowly push the plunger down. This will force the resin into the chip. You need to stop pushing about halfway down or where the clip stops your syringe or as per the instructions given.

●     Freeing any trapped air

You need to free any trapped air within the chip, and for that, you have to remove any tint on the window and then knock it gently. If there is a small space within the crack or chip that is not filled, you can further push your syringe down. But be careful right from the beginning.

●     Let the resin cure

Now you need to allow the resin to cure, and for that, you can reference the instructions and see for how long you need to keep the resin just the way it is so it can cure completely. Once it is completely cured, you can remove the pedestal as well as the adhesive patch.

●     Don’t need to wipe anything just yet

When you remove the patch and the pedestal, just keep in mind that you don’t need to wipe anything just yet. You must wrap your resin tube and put a couple of drops right on the crack or chip. Now grab your curling strip and place it right on top of the chip with a couple of drops of resin.

Now place it down at an angle so that you can avoid trapping any air bubbles. You need to hold the strip using your fingers as you see that razor blade for getting those air bubbles out. After that, you can allow it to cure for the time that is recommended in the instruction.

●     Use a razor for scraping the strip

You have to use a sharp razor blade for scraping off your curing strip. And make sure you don’t just pull it off. Just place your finger right on top of your chip and use a razor blade to break the bond between the glass and the strip right around the perimeter of that crack.

You finally have to twist the trip off and make sure not to pull it out, or you will risk pulling out the resin along with it from the crack as well. Scraping should be done perpendicularly to the windscreen glass to remove any resin that is left behind.
