A cracked windshield is one of the most common car issues drivers face. While small cracks may not seem serious at first, they can quickly spread and compromise both safety and visibility. Replacing a windshield can be costly, so many drivers look for temporary solutions to stop the damage from worsening until they can get a professional repair.
In this guide, we’ll explain how to fix a cracked windshield temporarily, the tools you’ll need, and when to seek professional help.
Why You Shouldn’t Ignore a Cracked Windshield
Even a tiny crack can:
- Obstruct your view while driving
- Reduce the structural strength of the glass
- Spread due to temperature changes or vibrations
- Lead to fines if your local laws require windshield integrity
That’s why temporary windshield crack fixes are useful — they buy you time until a permanent replacement is possible.
Temporary Fixes for a Cracked Windshield
1. Clear Nail Polish or Super Glue
- Clean the cracked area with mild glass cleaner and a microfiber cloth.
- Apply a thin layer of clear nail polish or super glue over the crack.
- Allow it to dry completely before driving.
This prevents dirt and moisture from entering and slows down crack expansion.
2. Windshield Repair Kit
Available online or at auto stores, these kits include resin and an applicator.
- Follow the kit instructions to inject resin into the crack.
- Let it cure under sunlight or UV light.
This creates a stronger seal compared to nail polish and works best on small chips or short cracks.
3. Clear Packing Tape
For larger cracks, apply clear packing tape over the surface.
- It won’t stop the crack from spreading but prevents dirt and water from entering.
- Only use transparent tape to avoid blocking your visibility.
4. Avoid Stress on the Glass
- Park your car in the shade to reduce heat stress.
- Avoid slamming doors, which can vibrate the crack.
- Drive carefully over bumps to reduce windshield pressure.
When to Get Professional Help
Temporary solutions only work for small chips and cracks (usually under 6 inches). You should immediately contact a professional if:
- The crack blocks your line of vision
- The damage is on the driver’s side
- The crack has spread across the windshield
- The glass shows multiple chips or spiderweb cracks
In such cases, windshield replacement is the safest option.
Final Thoughts
Fixing a cracked windshield with temporary solutions like nail polish, resin kits, or tape can help prevent further damage, but these are not long-term fixes. To ensure your safety on the road, schedule a professional repair or replacement as soon as possible.
