🧪 How to Make Your Own Window Tint Solution (Pro Guide by TMR Films)
Looking to install window tint like a pro without breaking the bank? Making your own tint solution is a simple, cost-effective method trusted by real installers — and we’re here to guide you step by step.
At TMR Films, we believe in empowering the tinting community. Whether you’re just starting out or fine-tuning your technique, this guide is for you.
🧰 What You’ll Need
- 1 Clean spray bottle (32 oz or 1 quart)
- 1 teaspoon of baby shampoo (preferably no added scents or conditioners)
- Clean water
🧪 Mix Your Tint Solution
- Fill the spray bottle with 1 quart of clean water.
- Add 1 teaspoon of baby shampoo.
- Shake well until evenly mixed.
💡 Pro Tip: Avoid creating too many suds—too much soap can leave streaks or film behind.
✅ How to Use the Solution Like a Pro
Spray Bottle Technique
- Set the nozzle to a fine mist.
- Spray evenly across the glass surface.
- Don’t oversaturate; less is more.
Positioning the Film
- Mist the glass surface before placing the tint.
- Start at the top and use a squeegee to slide it into place.
- Smooth air bubbles outward using overlapping strokes.
Prevent Film From Sticking to Itself
- Always keep both sides of the film wet during handling.
- Never fold or crease the film.
- If it does stick, separate carefully with a damp, gloved hand or soft squeegee.
🔐 Safety & Storage Tips
🧴 Baby Shampoo Safety
- Keep away from eyes and kids.
- Store in a clearly labeled bottle.
- Mix new solution every 2–4 weeks for best performance.
🚫 Avoid These Mistakes
- Using tap water with heavy minerals (distilled is best).
- Using too much soap.
- Not testing the spray bottle before application.
