Patching and Insetting: Replacing Only the Damaged Small Piece

A close-up of a column base. The decayed part has been vertically cut out and replaced with a new piece of wood joined to the old material with a diagonal cut or a tenon joint, with the seam clearly visible. Next to it, a few weathered bricks in the brick wall have been dug out and replaced with new ones. The new bricks are slightly lighter in color, and the mortar joint technique is consistent with the old one. Avoid: replacing the entire column, filling the defects with cement mortar, using new bricks with colors and sizes too different from the old ones, sanding down and hiding the seams.

一根柱子的柱腳特寫。腐朽的部分被垂直切除,換上一段新木以斜面或榫接與舊材接合,接縫清楚可見;旁邊的磚牆有幾塊風化的磚被挖出換新,新磚的顏色略淺,灰縫的做法與舊的一致。避免:整根柱子換新、用水泥砂漿把缺損填平、新磚的顏色與尺寸與舊磚差太多、把接縫磨平藏起來。
