- If necessary, use a plastic scraper to remove any dirt or debris from the crack.
Apply Windshield Repair Kit:
- Follow the instructions provided with the windshield repair kit. Typically, this involves injecting a resin into the crack.
- Use the applicator found in the kit to fill the crack completely, ensuring there are no air bubbles.
- Allow the resin to cure as per the manufacturer’s instructions (generally a few hours).
Finish the Repair:

- Clean the area again to remove any excess resin.

For Large Cracks (Replacement)

Prepare the Workspace:
- Park the vehicle in a shaded area and ensure it is on a flat surface.
- Gather all tools and have the replacement windshield ready.
Remove the Old Windshield:
- Use interior trim removal tools to carefully remove any trim or molding around the windshield.
- Use suction cups to lift the windshield slightly.
- Cut the urethane adhesive using a utility knife or windshield removal tool. Work your way around the edges until the windshield is free.
Install the New Windshield:
- Clean the frame of the vehicle to remove old adhesive and debris.
- Apply a bead of new urethane adhesive around the frame where the windshield will sit.
- Carefully position the new windshield onto the frame using suction cups. Ensure proper alignment with the frame.
- Press down firmly to ensure the adhesive makes contact with the glass.
Secure the Windshield:
- Reinstall any trim or molding removed earlier.
- Allow the adhesive to cure as per the manufacturer's instructions (usually 24 hours).
Final Checks:
- Inspect the installation for any gaps or misalignments.
- Check for any leaks by pouring water over the windshield and watching for any drips inside the vehicle.
