Introduction
A small chip in your windshield may not seem like a big deal, but if left untreated, it can quickly turn into a large crack—requiring full windshield replacement. Learning how to repair chip on windshield can save you time, money, and the hassle of more serious damage down the road. This guide breaks down everything you need: what kind of chips can be repaired, tools required, step-by-step instructions, and tips for preventing further damage.
What Types of Windshield Chips Can Be Repaired?
Not all chips are the same. Repair kits and professional services can usually fix:
- Bullseye chips (round, dark center)
- Star breaks (spider-like cracks)
- Combination chips (small cracks from a central break)
Chips That Are Repairable:
- Less than the size of a quarter (about 1 inch)
- Not in the driver’s direct line of sight
- Not at the edge of the windshield
- Not too deep or penetrating multiple layers of glass
Tools and Materials Needed
- Windshield repair kit (available at auto parts stores)
- Clean, lint-free cloth
- Razor blade or safety pin
- Glass cleaner
- UV light (optional, but helpful)
- Masking tape (optional)
Step-by-Step: How to Repair Chip on Windshield
Step 1: Inspect and Clean the Area
- Use a flashlight to assess the depth and shape of the chip.
- Clean the area using glass cleaner and a lint-free cloth.
- Remove loose glass particles with a pin or razor blade.
Step 2: Position the Repair Device
- Apply the adhesive base from the kit directly over the chip.
- Attach the bridge or injector from the kit on top of the adhesive base.
Step 3: Inject the Resin
- Load the resin into the injector.
- Tighten the injector screw to apply pressure and force the resin into the chip.
- Let it sit for 5–10 minutes (follow your kit’s instructions).
Step 4: Release Pressure and Let Resin Settle
- Loosen the injector slightly to allow air bubbles to escape.
- Re-tighten to reapply pressure for another 5 minutes.
- Repeat if necessary to fill the entire chip.
Step 5: Remove the Device and Apply Finishing Resin
- Detach the repair tool.
- Apply a small drop of finishing resin to the surface of the chip.
- Place a curing strip (included in the kit) over the area.
Step 6: Cure the Resin
- Let the resin cure in direct sunlight for 15–30 minutes.
- Use a UV light for faster curing if you’re indoors or it’s cloudy.
Step 7: Clean and Polish
- Remove the curing strip.
- Use a razor blade to scrape off any excess dried resin.
- Wipe clean with a glass cleaner and cloth.
Tips for Best Results
- Work in a shaded area to prevent resin from curing too quickly
- Don’t repair in freezing or very hot conditions
- Perform the repair as soon as possible after the chip forms
- Avoid washing the car or exposing it to moisture for at least 24 hours
When to Call a Professional
- The chip is in the driver’s line of sight
