THE SIX DIFFERENT TYPES OF WINDSHIELD BREAKS

The Six Different Types of Windshield Breaks and How The Affect Your Repair Strategy

If you need advice on how to tackle the different types of windshield breaks, you need to know what to look for. With the price of replacing a windshield getting more exorbitantly expensive, most people are left with only one option: an auto glass business that has a windshield crack repair kit. We know that finding the best windshield crack repair kit for your customers can take a bit of homework to find, but it can go much more smoothly when you know exactly which windshield repair technology works best for which type of damage.

The Six Kinds Of Breaks

Surface Pit

These are typically the size of a pinhead and can be repaired but not charged for especially not billed to an insurance company because it technically is not a break.They only involve a chip in the glass that not extended into the middle tension zone has been removed a minute piece of glass to form a very small crater, or a 'pit'. These surface pits are easily repaired using the windshield repair resin 90 cps and a solid uv cure. After each repair you do, we always top of with a drop of 90 cps to ensure a good seal.

Bullseye Break

This kind of break looks like it sounds. A circular cone shaped break that usually stems from a small rock kicked up by traffic that collides with your windshield. These are larger than surface pits and can always be repaired with a windshield crack repair kit and never require a glass replacement. This is the only break that a DIY (do-it-yourself) kit can effectively repair. The bullseye was very common when windshields were thicker. Nowadays the outer lite is only 2mm thick and combination breaks more often bullseyes.

Half Moon Crack

These are essentially half a bullseye and leave the same black-like appearance, but they aren't circular but shaped like a half moon instead. In most cases this type of break is caused by a stone and thus makes this more of a chip. These are not too common. Most of the time you will see the other break, bees-wing break, but has very similar characteristics. Neverthless its more of an advanced chip to repair.

Star Break Break

Much like different types of bullseye breaks, a star break leaves an indentation at the impact site. The difference is the outward break pattern which here takes the appearance of a star. Straight cracks come out of the center of the crater rather than circles. This can be more time consuming to repair than bullseyes. In more situations you will need to use special tools to fill the legs of a star-break with resin. Some of these star breaks will have up to three to four legs. Ultra Bond has the Wonderbar to help you open up the windshield.

Long Crack

When you see a straight single line in your windshield, this is a crack. 9 out of 10 will be coming off the edge of the windshield called an edge crack. Edge cracks are easy to repair up to about 18 inches long with the right tools and resins. The other crack is called a floater crack. This one is a chip or stone-break that cracked out. This crack will not run to the edge of the windshield. The floater crack is more time consuming to repair and takes more crack-opener tools than an edge crack.

Combination Crack

These are the most visible of all breaks and cracks after repair. A combination break is where you see a round shaped bullseyes break with a star-break inside of it. It will often have crushed glass around the impact point. This break should not be repaired if it is in the driver's vision. To repair this one, you will need the Ultra Bond Crack Master Bridge. This type of break will also need the use of the Wonder Star Flexor that will keep you from having a harder time with the legs in this combination crack.

The best types of windshield crack repair resin to use for repairing glass can vary. Viscosity plays a big role in how restorative the resin will be. Less viscous resins will work alright for smaller dings, but you will need much more viscous and resilient resin for professional jobs. In addition, long cracks will require specific types of tools and resins that are in our windshield crack repair kits, whereas bullseyes, stars, combination breaks and other small chips can be restored with our standard windshield repair kits.


Always evaluate a break or crack before rendering services to repair it, because sometimes the windshield must be replaced.
