Have you discovered a big crack or a wide chip on your vehicle’s windscreen? However bad you might feel, you have no other option but to replace it.
Are you surprised at how auto glass service professionals ensure that the replaced windshield always stays in place?
We’ll go over the step-by-step procedure for windshield replacement and the best approach to applying urethane windshield adhesive to help it stay in place.
Materials and Tools Needed
So, what are the tools required to replace your windshield? Besides the obvious new windshield and the auto glass adhesive, you might need the following:
- Utility knife for cutting the rubber gasket and removing the windshield from the pinch weld
- Glass cleaner to clean the new windshield and the windshield perimeter
- Working gloves for safety
- Lint-free cloth for cleaning
- Razor blade to remove the old urethane
- Urethane primer, which is to be applied before the urethane windshield adhesive
- A caulking gun to lay a bead of glass adhesive around the windshield frame
Preparing the Surface
Make sure to prepare the installation area before windshield replacement.
- You can remove the wipers from the windshield.
- Detach the rearview mirrors as well.
- Remove the damaged windshield from the pinch weld.
- Use a knife to remove the urethane shield from the windshield frame.
- Clear the empty windshield frame of rust using sandpaper or a stiff nylon brush. Vacuum the area to clear any debris.
Once you are done with prepping the surface, you should follow up with the next steps.
Applying the Primer
Clean the windshield perimeter with glass cleaner, and then apply the urethane primer. It is generally applied to the place where the windscreen adhesive and the windshield are fixed to protect the frame from rust and damage.
Applying the Adhesive
This is the most important segment of the windshield installation process. The success of your windshield installation depends on whether the urethane windshield adhesive has been applied correctly.
Here are the things you need to keep in mind while applying the car window adhesive.
- The right application method for a glass adhesive is known as a V bead, and the windshield adhesive is in the shape of a pyramid or an upturned “V” (^).
- The wide base of the pyramid lies on the pinch weld, while the tip of the pyramid points out towards the outside of the vehicle.
- Make sure to place the pyramid-shaped urethane windshield adhesive bead upright on the windshield surface. The tip of the pyramid should touch the windshield glass for proper adhesion and bonding.
Here is a detailed insight into how to apply the urethane windshield adhesive.
- You can either start at the bottom or top of the windshield frame. You need to hold your caulking gun (electronic or air-powered) at a 90-degree angle to the pinch weld. This ensures that the V bead of the glass windshield stands straight up when dispensed.
- If the vehicle is too big, it becomes difficult to apply the V bead in a perpendicular direction in certain places. Dont worry! Just place the bead on the windshield glass and use a setting tool.
- Also, it is advisable to apply the bead continuously to the pinch weld. Make sure the ends of the beads touch when you start with the next tube after you run out of windshield adhesive.
Setting the Glass
Once you are done applying the windshield adhesive, place your new windshield on the frame and align it correctly. Press on it softly to ensure a snug fit.
Curing Time and Post-Application Care
Your new windshield glass is most vulnerable to damage within 24–48 hours after replacement.
- To avoid damage, allow the glass to sit for at least 24 hours, if not longer, for the windshield adhesive to cure.
- Make sure not to drive, expose to rain, or wash the car within 24 hours of applying the windshield adhesive.
- Removing the plastic covers from the windshield before the glass adhesive has cured is a strict no-no.
- Do not lean on the windshield within 24 hours of applying the windshield adhesive.
Things to Remember
Remember not to use the wrong adhesive. Steer clear of bathroom caulking or silicone, and use products specifically designed for use as windshield adhesives. Always use Urethane windshield adhesive, which is 90 times stronger than other adhesives. This prevents the windshield from coming off the frame during an accident.
Caring for Your Adhesive
You can care for your windshield’s adhesive with these simple tips.
- Try not to park your windshield in direct sunlight, which can weaken the adhesive over time.
- Always prefer professional windshield replacement. Adhesives available in stores don’t serve the purpose.
- Follow through with the advice of your auto glass repair technicians to care for your windshield’s adhesive.
Conclusion
Urethane windshield adhesive is the first choice of professionals. It can withstand extreme temperatures and weather conditions. However, the glass adhesive needs to be applied correctly for the best results.
It is always advisable to seek professional auto glass service for windshield replacement. You can be assured of a perfect installation and the right adhesive application.
