How To Stop A Windshield Crack From Spreading
What Is A Spider Crack In A Windshield?
There are different types of damage that happen to windshields. The size, shape, and depth of the damage play a big role in if it can be repaired or of the windshield needs to be replaced. The guide to the right shows different shapes and has a guide to the size of damage where you can get an idea of if the damage your windshield can be repaired, or if you will need a replacement windshield.
Spider cracks, for example, will originate from a small chip in the auto glass. The crack will start to expand across the windshield, resembling the threads of a spider web. These fissures are located on both the inner and outer panes of glass. Oftentimes, these cracks are spotted on the edges of the windshield.
Spidering happens around the point of impact, typically caused by a small piece of debris out on the road. While this can be quite small in size, the eventual long cracks will pose safety concerns when left untouched.
What Causes Spider Cracks?
In some cases, extreme temperature changes can result in these unfortunate windshield cracks. These sudden shifts in temperature can weaken the glass overall, making it susceptible to spidering.
Here are some potential causes of spider cracks:
- Sudden temperature changes.
- Collisions.
- Poorly installed and maintained windshield.
- Small debris.
- Hail, ice, and other storms.
How To Stop Windshield Cracks From Spidering
Begin this task by using one of the outlined methods below to either stop windshield cracks from spidering temporarily or over the long run. At the very least, these methods can be used as a quick fix before professional repair is available.
Method 1. Apply Clear Tape
- Use glass cleaner and a microfiber cloth to clean the area surrounding the crack.
- Remove any debris from the crack with the help of a push pin.
- Completely cover the crack with strong, transparent tape.
Method 2. Use Super Glue Or Nail Polish
- With glass cleaner sprayed onto a rack and not the crack directly, clean the cracked area.
- Use a needle or push pin to remove debris from inside the crack carefully.
- Apply a tiny amount of nail polish or super glue in order to fill this crack.
- Wipe away any excess, letting it dry for at least two hours before driving the vehicle.
Method 3. Windshield Repair Kit
- A windshield repair kit can be purchased from a local hardware store or auto shop.
- Use this to clean and dry the area while removing debris with a sharp object.
- Load the adhesive or resin into the kit’s applicator, positioning it over the crack.
- Inject this into the crack and allow it to cure according to the kit’s instructions.
How To Prevent Further Windshield Damage
To prevent any further windshield damage, it’s important to avoid driving on rough and bumpy roadways. This will reduce the vibration stress put on the crack.
Rain can also be hazardous to drive in for the windshield crack. Try to always park under shelter or in shady areas to minimize temperature fluctuations.
Repairing Vs Replacing A Windshield With Spider Cracks
Repairs can be made to these cracks, but this is simply a temporary fix. Spider cracks will only spread as time goes on, which means a full replacement is the only solution.
Keeping the windshield clear of any dirt and debris, while also applying some gentle cleaning methods can help slow the spread of these cracks.
Take these precautions in order to prevent the cracks from expanding:
- Refrain from driving in harsh weather conditions.
- Position fans away from the windshield.
- Do not park directly in the sun.
- Do not turn the AC on immediately after starting the car.
Once spidering is visible, it’s always best to contact the auto care professionals. Any repairs are simply temporary when it comes to this specific windshield issue.
