A well-installed window tint enhances privacy, blocks harmful UV rays, and improves the aesthetics of your vehicle. But when your tint starts turning purple or forming bubbles, it not only looks bad but also loses its effectiveness. If you’re facing these issues, you’re not alone. In this guide, we’ll break down why it happens, how to fix it, and how to prevent future tint problems.
Key Takeaways:
- Purple tinting is caused by dye breakdown due to prolonged UV exposure.
- Bubbling occurs due to poor installation, adhesive failure, or trapped moisture.
- Cheap, non-metallic dyed films are more prone to discoloration.
- Proper installation and high-quality film can prevent these issues.
- Timely replacement is the only solution for severe tint damage.
Common Reasons for Window Tint Turning Purple
1. Dye Breakdown from UV Exposure
Most inexpensive window tints use dyed film, which consists of a layer of dye that absorbs sunlight. Over time, UV rays break down the dye molecules, leading to color fading and an unsightly purple hue.
How to Prevent It:
- Choose ceramic or carbon-based tint films, which are more UV-resistant.
- Park in shaded areas or use a car cover to limit sun exposure.
- Regularly clean your tint with ammonia-free tint-safe cleaners to prevent further degradation.
2. Low-Quality Tint Film
Cheap, non-metallic dyed films lack UV stabilizers, making them more prone to fading and discoloration.
Best Solution:
- Upgrade to high-performance window films such as metallic, carbon, or ceramic tint.
- Opt for brands offering lifetime warranties to ensure longevity.
Why Is My Window Tint Bubbling?
1. Adhesive Failure
Poor-quality films have weak adhesives that fail over time, leading to bubbling and peeling.
Fix:
- If the bubbling is minor, use a heat gun and a squeegee to smooth out the tint.
- If bubbles persist, replacing the tint is the only effective solution.
2. Improper Installation
Trapped air bubbles form when tint film isn’t installed correctly, especially if the surface isn’t properly cleaned.
Prevention Tips:
- Always get tints installed by certified professionals.
- Ensure thorough cleaning of windows before application.
3. Moisture Trapped Under the Film
Water or soap residue left behind during installation can lead to bubbling as the adhesive weakens.
What to Do:
- If you just had your tint installed, allow a few days for bubbles to settle.
- For persistent bubbles, consult a professional to assess whether a reinstallation is needed.
How to Fix Purple or Bubbling Window Tint
| Issue | Solution |
|---|---|
| Purple Tint | Replace with ceramic or carbon film |
| Bubbling Tint (small) | Use heat gun and squeegee to smooth |
| Bubbling Tint (large) | Reinstall with professional help |
| Peeling Tint | Remove and install a new, high-quality tint |
How Long Does Window Tint Last?
The lifespan of window tint varies based on the type of film used:
- Dyed film: 2-5 years
- Metallic film: 5-10 years
- Carbon film: 7-10 years
- Ceramic film: 10+ years
Conclusion
If your window tint is turning purple or bubbling, the root cause is likely low-quality film, UV exposure, or poor installation. While minor bubbling may be fixable, severely damaged tint requires complete replacement. Investing in high-quality window tint ensures better durability, protection, and aesthetics for your vehicle.
For best results, always choose trusted professionals for installation and maintenance. By following these tips, you can avoid common tint issues and keep your car looking its best for years to come.
