Stucco or
render (
Persian: گچ بری Gachbori) is a material made of an
aggregate, a
binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as decorative coating for walls and ceilings and as a sculptural and artistic material in architecture. Stucco may be used to cover less visually appealing construction materials such as
metal,
concrete,
cinder block, or clay
brick and
adobe.
