Fitting a windscreen is a precise job that ensures the structural integrity and watertight seal of your vehicle. It typically involves several key stages performed by trained technicians after the old windscreen has been safely removed.
Overview of Windscreen Fitting
The process of installing a new windscreen is more than just placing glass into a frame. It requires careful preparation, the correct application of specialized adhesives, and precise placement to ensure safety and prevent leaks. While the specifics can vary slightly between vehicle models, the core steps remain consistent.
Key Steps in Fitting a New Windscreen
Once the damaged windscreen is out and the aperture is clean, fitting the new one involves these critical stages:
- Surface Preparation: The frame or aperture where the windscreen sits must be meticulously cleaned and prepared. This includes removing old adhesive residues and ensuring the metal surface is sound. Crucially, this stage includes preparing the surface for any areas that may need treatment, such as minor corrosion spots, to ensure the adhesive bonds correctly and prevents future issues.
- Primer Application (if required): Depending on the adhesive system used and the vehicle's frame material, a primer may be applied to enhance the bond between the glass and the adhesive.
- Adhesive Application: A high-strength adhesive, typically a specialized urethane or glue designed for automotive glass, is applied. This adhesive is applied in a continuous bead. As noted in the process, the glue or urethane is applied to the edge of the frame or aperture, creating the seal that holds the glass in place and makes the vehicle airtight and watertight.
- Windscreen Placement: The new windscreen is carefully lifted and precisely placed into the adhesive bead on the vehicle's frame. Proper alignment is vital for a good seal and correct fit.
- Securing and Curing: The windscreen is gently pressed into the adhesive and may be temporarily taped or secured to hold it in position while the adhesive cures. The curing time allows the adhesive to harden, forming a strong, durable bond. The specific curing time varies depending on the adhesive type and environmental conditions.
- Refitting Trims and Components: Once the adhesive has adequately cured (often to a point where the vehicle is safe to drive), surrounding components are refitted. This includes exterior trims, wipers, and mirrors. Additionally, as part of the process, the inner trims are refitted, restoring the interior finish around the windscreen.
Following these steps ensures the new windscreen is correctly fitted, providing necessary protection and contributing to the vehicle's structural strength.
