What Is Resin Injection?
Resin Injection is a windshield repair process that fills a chip or small crack with clear resin. The resin enters the damaged glass through a controlled opening or repair bridge. Pressure helps the material reach the air pockets inside the break. The resin then cures and bonds within the glass, improving appearance and limiting further spreading.

Key Takeaways About Resin Injection
- Resin flows into hidden air spaces inside damaged laminated glass.
- Clean, stable damage gives the repair material better access.
- Resin Injection isn't the same as replacing the windshield.
How Resin Injection Works
Resin Injection moves repair resin into the open spaces within a windshield chip or small crack. A repair tool creates a sealed path over the damage. The technician may alternate pressure and vacuum so the resin reaches areas that contain trapped air.

After the resin fills the break, curing changes the liquid material into a solid bond. The finished repair can improve clarity and help stabilize the damaged area. Results depend on the damage pattern, its location, cleanliness, and whether moisture or dirt has entered the break.
Windshield Repair commonly uses this process for impact damage in laminated glass. Surface resin may be added after injection to fill the entry point and smooth the repaired area.

When we assess Resin Injection, we check the damage pattern, location, cleanliness, and signs of moisture. We clean the impact area before placing the repair tool. After injection, we inspect the cured resin and the surrounding glass for remaining air or visible changes.
Resin Injection in Practice: A Real-World Example
A vehicle arrives with a fresh stone chip in the windshield. The technician cleans the impact point, places a repair bridge over it, and injects resin until the open spaces are filled.
