stukwerk

Stukwerk is decorative plasterwork used in architecture, especially on interiors such as ceilings, walls, friezes, cornices, and ornamental medallions. It is produced by stucadoors using lime-based or gypsum-based plaster that is applied in thin layers over lath or solid surfaces and modelled into reliefs, mouldings, and carved motifs. In many Dutch and Flemish interiors of the 17th to 19th centuries, stukwerk forms elaborate schemes combining sculpted reliefs, rosettes, acanthus leaves, cartouches, and coffered ceiling patterns. The craft often involved plaster moulds and freehand carving, and was frequently painted or gilded as part of the decor.

History and scope: Stukwerk flourished in the Low Countries during the Dutch Golden Age, continuing into later Baroque, Rococo and Neoclassical phases. It was commonly used in churches, town houses, guild halls, and palaces; prominent centers were Amsterdam, Haarlem, Delft, and Flemish cities. Exterior plasterwork existed but was less common; window surrounds, cornices, and façade reliefs were sometimes executed in a stucco-like finish to imitate stone.

Materials and techniques: Lime plaster was standard historically; gypsum plaster became widespread in later periods. Techniques ranged from incised reliefs done directly in plaster to the use of wooden moulds to cast decorative elements, later attached to surfaces with nails or additional plaster.

Conservation: Restoring stukwerk requires expertise in traditional plastering and colour restoration; issues include cracking, dampness, and loss of the lime binder. Conservation aims to preserve original material and technique whenever possible.
