Building-to-building pressure causes many walls to crack, form sand holes, and have holes, allowing rainwater to seep through these cracks into the walls. When the rain washes against the exterior walls, leakage spots appear on the interior walls.

Environmental factors' impact on structural adhesive aging
1. During the actual application of curtain walls, it is inevitable to be affected by surrounding environmental factors, such as rain, UV radiation, and high temperatures. These factors can lead to discoloration, bubbling, cracking, and even脆ification, cracking, and delamination, reducing the service life and severely affecting the safety of the curtain wall project.
2. The glue application is not dense; there's no proper control over the amount of glue at the joint during the collection process, resulting in excessively thin glue thickness. Since the aging of weather-resistant glue progresses from the surface to the depth, insufficient depth of the glue will lead to premature cracking and leakage. If the sealing of the threaded holes is not tight or there are omissions, it will create water leakage pathways.
