Purchase a high-quality windshield adhesive specifically designed for your vehicle. Follow the manufacturer’s instructions for mixing and applying the adhesive. Typically, the adhesive is applied to the frame of the vehicle, not the windshield.
Use a sponge or a brush to apply the adhesive evenly along the frame. Apply a thin, continuous bead of adhesive, avoiding any gaps or thick spots. Make sure the adhesive is applied to all contact points between the frame and the windshield.
Once the adhesive is applied, carefully place the windshield into the frame. Align the windshield correctly and press it firmly into place. Use a rubber mallet or a tapping block to ensure proper adhesion and seating of the windshield.
Allow the adhesive to cure completely before driving the vehicle. The curing time varies depending on the type of adhesive used and the environmental conditions. Consult the manufacturer’s instructions for specific curing times.
| Product | Curing Time |
|---|---|
| Urethane Adhesive | 1-2 Hours |
| Silicone Adhesive | 6-12 Hours |
Additional Tips:
- Use a primer on the windshield frame and the new windshield to enhance adhesion.
- Apply masking tape around the windshield frame to prevent adhesive from getting on the paint.
- If the windshield is large or heavy, consider using suction cups or a hoist to assist with the installation.
- Do not drive the vehicle until the adhesive is fully cured.
Reattaching Windshield
Once the new windshield is in place, it’s time to reattach it. This process is similar to removing the old windshield, but in reverse order.
1. Apply a bead of urethane around the perimeter of the windshield frame.
2. Carefully lower the windshield into place, making sure that the urethane bead is evenly distributed around the frame.
3. Use masking tape to hold the windshield in place while the urethane cures.
4. Allow the urethane to cure for at least 24 hours before driving the vehicle.
Special Considerations for Reattaching Windshields with ADAS Systems
If your vehicle is equipped with an Advanced Driver Assistance System (ADAS), there are a few additional steps you need to take when reattaching the windshield.
1. Calibrate the ADAS system after the new windshield is installed.
2. Make sure that the windshield is properly aligned with the ADAS sensors.
3. Test the ADAS system to make sure that it is working properly.

Finishing Touches
After the windshield is set in place, use clean cloths or paper towels to wipe away any excess Sikaflex from the edges of the glass and the frame. You can also use a plastic scraper to carefully remove any stubborn residue. Be sure to clean both the interior and exterior of the windshield.
Once the windshield is clean, apply a bead of silicone sealant around the edges of the glass, both inside and out. This will help to seal the windshield and prevent leaks. Allow the silicone to dry completely before driving the vehicle.
Curing Time
The curing time for the Sikaflex adhesive will vary depending on the temperature and humidity. In general, it will take around 24 hours for the adhesive to fully cure. However, it is best to allow the adhesive to cure for as long as possible before driving the vehicle. This will give the adhesive time to fully bond to the glass and the frame, and will help to prevent the windshield from leaking.
The following table provides an overview of the curing time for Sikaflex adhesives at different temperatures:
| Temperature | Curing Time |
|---|---|
| 77°F (25°C) | 24 hours |
| 68°F (20°C) | 48 hours |
| 59°F (15°C) | 72 hours |
If the temperature is below 59°F (15°C), it is best to wait until the temperature rises before applying the adhesive. This will help to ensure that the adhesive cures properly.
