砖是坚硬,但多孔的材料。
水分穿透这些小孔,随着时间的推移,即使是最微小的小孔也会逐渐扩大,并最终导致砖出现裂痕。
如果不妥善密封,水分会渗透到家里的墙上,从而导致霉菌和霉菌生长,所以建议你尽快密封砖墙。
处理方法是coat it with masonry sealant (用砖石密封胶涂层),不复杂,自己就可以做。
这种现象在有一定年代的砖房里是比较常见的,但才两年新的房子就出现这种情况则不多见,建议尽快处理。
大家看一下brick/masonry sealant的用途介绍吧,就清楚它具有water repellent的作用了。
The brick/masonry sealant “makes” brick and masonry water repellent. It penetrates below the surface and leaves no surface coating to wear away. It is 100% breathable and allows interior moisture to escape the building. Brick spalling, efflorescence and flaking will be reduced after application。作者: 品质生活 时间: 2012-7-27 23:27:23

这回说的靠点谱,一定要有repellent功能的才行。否则就害人了。一般我们工地叫它sealer。
你给的youtube连接的标题也说了是water repellent。
Youtube的标题:A-Tech Masonry and Brick Sealer-water-based silane/siloxane water repellent
Youtube的内容:Shows application of A-Tech Masonry and Brick Sealer water-based water repellent.
