The compression between buildings leads to many walls developing cracks, sand eyes, and holes. Rainwater seeps into the walls along these cracks, washing onto the exterior walls, and causing water leakage into the interior walls.

Environmental factors' impact on the aging of structural adhesives
1. During the actual application of curtain walls, it is inevitable to be affected by surrounding environmental factors. Such as: rainwater, ultraviolet radiation, and high temperatures, which can lead to discoloration, bubbling, cracking, and even脆ification, cracking, and adhesive failure during use, reducing the service life and severely affecting the safety of the curtain wall project.
2. The adhesive application is not dense; there's no precise control over the amount of adhesive at the joint during curing, resulting in overly thin adhesive layers. Since the aging of weather-resistant adhesive progresses from the surface to the depths, insufficient depth leads to premature cracking and leakage. Issues like inadequate sealing of threaded holes or omissions can create water leakage pathways.
