How to Temporarily Repair a Cracked Windshield
It's a scenario I've been in before – you're driving along, and suddenly, a rock or piece of debris strikes your windshield, causing a crack. In my case, I was on a long road trip, and I didn't have the time or resources to get it fixed immediately. So, I needed a way to manage the cracked windshield until I could get it professionally repaired. If you find yourself in a similar situation, it’s essential to know how to repair a cracked windshield temporarily to prevent further damage and ensure your safety.

1. Why It's Important to Address a Cracked Windshield Quickly
The windshield of your vehicle is a crucial safety feature. It protects you from debris, weather elements, and even in the event of a crash, it helps to keep the integrity of the cabin intact. When a crack appears, it can compromise the windshield's ability to protect you, especially if it’s in the driver’s line of sight. Additionally, the crack can worsen over time due to temperature fluctuations, pressure, or even simple vibrations from driving. I learned this lesson the hard way when a small chip turned into a large crack on my windshield during a hot day. That’s why it’s essential to address the issue as quickly as possible.

2. Identifying the Type of Crack
Before attempting any repairs, it's crucial to identify the type of crack you’re dealing with. There are several types of windshield cracks, and knowing which one you have will help determine the best approach for a temporary fix. Here's a breakdown of common types of cracks I've encountered and the ones I suggest looking out for:
- Star Break: This is when the crack spreads outward from a central point, resembling a star. It can easily worsen if left untreated.
- Chip: This is a small, round damage that doesn’t extend very far but can be a gateway for bigger cracks if it isn’t sealed quickly.
- Long Crack: These cracks are longer than a foot and are the most difficult to repair temporarily. It’s important to address them quickly to prevent further damage.
- Edge Crack: These types of cracks occur at the edge of the windshield and can spread quickly if not handled properly. This was the type of crack I had to manage on a trip out of town.
3. Temporary Repair Solutions
When you find yourself with a cracked windshield and need a quick fix, there are several methods you can try. Here are the steps I took when I encountered a cracked windshield, and I found them to be effective for temporary repairs:
Step 1: Clean the Area Around the Crack
Before applying any kind of sealant, cleaning the crack and the area around it is essential. Dirt or debris can interfere with the bonding process and prevent the repair from being effective. I used a soft cloth and some water to gently clean the area around the crack. Make sure to dry it completely, as any moisture can affect the repair materials.
Step 2: Apply Clear Tape Over the Crack
One of the most common and simplest methods I used was applying clear tape over the crack. This temporary fix works by holding the crack in place and preventing dirt and moisture from getting in. Use a strong adhesive tape, like clear packing tape, to cover the crack. Make sure the tape is smooth and securely attached on both sides of the crack. This is a quick fix to keep the crack from getting worse while you arrange for a more permanent solution.
Step 3: Use a Windshield Repair Kit
If you’re looking for a more solid temporary fix, a windshield repair kit is a great option. These kits usually include resin that you apply directly into the crack, which can help seal it temporarily. I used a windshield repair kit that I bought from an auto parts store, and it was surprisingly effective. The kit included a special applicator and resin that filled the crack and hardened it. It doesn’t restore the strength of a new windshield, but it helped to prevent further spreading of the crack until I could schedule a professional repair.
Step 4: Apply Superglue for Small Cracks
For smaller cracks or chips, I found that applying superglue was an effective method. First, clean the crack thoroughly, and then apply a small amount of superglue. Gently press the crack together and hold it for a minute to allow the glue to bond. This is a quick and easy fix for small chips, although it should only be used temporarily and doesn't work for larger cracks.
4. When to Call a Professional
While temporary fixes are great in an emergency, I always recommend getting professional help when possible. Windshield repair specialists have the proper tools and resins to fix the crack completely. They can ensure the repair is durable and safe. If the crack is large or if it’s located in your direct line of sight, it’s best to consult a professional as soon as you can. I learned this after my temporary fix started to wear off, and I needed to have the windshield replaced entirely.
5. How to Prevent Further Damage
After performing a temporary fix, there are a few steps I took to prevent further damage to my windshield until I could get a permanent solution. Here are some preventative tips:
- Avoid Sudden Temperature Changes: Extreme heat or cold can cause the crack to expand rapidly. On hot days, try to park your car in the shade, and avoid using your defroster or air conditioner directly on the windshield.
- Don’t Drive at High Speeds: Driving at high speeds can put pressure on the crack, causing it to expand. I made sure to drive slowly and avoid any bumpy roads.
- Avoid Direct Impact: Try not to hit any bumps or potholes while driving, as the shock can worsen the crack.
Taking these precautions can help prolong the life of your temporary repair, but I recommend scheduling a permanent fix as soon as you can to ensure your safety on the road.
