Architectural reproduction and restoration specialists use Polytek liquid mold rubbers to make site molds of aging/damaged ornate architectural elements (e.g., columns, brackets, panels, cornice moulding, statuary). From these molds, reproductions of damaged elements can be cast in the controlled environment of a mold shop.
In the tutorial below, we visited a commercial building that was being updated for reopening. A series of identical plaster columns lined the large space and some were damaged. To replace the damaged columns, a rubber mold was made of an identical intact column in order to cast plaster replacements.
