Paint and Plaster Layers: Peeling Them Off One by One

An interior wall with an exploratory window. Several palm-sized square test areas are opened on the wall, each peeled to a different depth, revealing plaster and paint colors from different eras, with dates and numbers marked next to them. The rest of the wall remains untouched. This serves as the basis for deciding which layer to restore. Avoid: directly peeling the entire wall to the bottom layer, repainting based on memory, removing the exploratory window and losing the decision-making process, using chemical agents for large-area cleaning.

一面做了試驗窗的室內牆。牆上開了幾塊巴掌大的方形試驗區,每一塊剝除到不同的深度,露出不同年代的粉刷與彩繪顏色,旁邊標註年代與編號。其餘牆面維持現況未動。這是決定要恢復到哪一層的依據。避免:直接把整面牆剝到最底層、憑印象重畫彩繪、拿掉試驗窗讓決策過程消失、用化學藥劑大面積清洗。
