Concrete: Seepage and mold

An old concrete wall. The surface retains rough formwork marks, but it is covered with numerous traces: dark water stains and efflorescence from water seepage, black and green mold patches, exposed rusted rebar, and holes that have been chiseled out and patched up. The lower section of the wall has a dark band from water immersion. These are not designed, but caused by time and environment. Avoid: clean fair-faced concrete, repairing water stains and mold patches, making the surface smooth and undamaged, using faux-aging coatings to simulate.

一面老舊的混凝土牆。表面保留粗糙的板模痕跡,但上面有大量的痕跡:滲水形成的深色水漬與白華、發霉的黑綠斑塊、裸露生鏽的鋼筋、被鑿開又補上的洞。牆的下段有被水浸過的深色帶。這些不是設計的,是時間與環境造成的。避免:使用乾淨的清水混凝土、把水漬與霉斑修補乾淨、讓表面平整無破損、使用仿舊的塗裝模擬。
