On the land of North China, compose the legendary movement of the industry
1. Improper construction, including missing silicone, cutting corners, or not constructing according to the drawings, and the two-component polysulfide sealant is not filled with the interface, which will cause waterproof failure, which is more lethal.
2. When external forces, water factors, gaps and other factors exist, it is inevitable that there will be water leakage, leakage of sealant, or cutting corners, or not constructing according to the drawings, all of which will result in poor sealing It will leak water, and we should pay attention that the sealant fills the entire interface and is in full contact with the substrate, so as to ensure the good adhesion between the sealant and the substrate, and also to ensure the sealing Adhesive durability.
3. If the displacement capacity of the two-component polysulfide sealant can not reach the displacement of the interface, the weather resistance of the polysulfide sealant will be poor, and it will cause serious consequences such as insufficient anti-aging ability. The displacement capacity of the sealant is obviously reduced after aging, and the reason why it cannot meet the displacement of the plate is that the sealant with low displacement capacity is used, or even fake glue.
4. Because the three-sided bonding will limit the displacement ability of the sealant, if necessary, anti-adhesive can be used to avoid the three-sided bonding, and the joints are subjected to different forces, so the displacement is relatively large. Yes, pay attention to reserve expansion joints when designing, let the sealant bear the excess, and avoid the window frame directly colliding with the wall.
