stucco

A mixture of lime or gypsum, sand, and water that is applied to the walls of structures as a sealant. In the Southwest, many pueblos are made of adobe, which comes from the Spanish verb adobar, meaning “to plaster.” Part of the annual maintenance cycle of pueblo structures can include the ritual of whitewashing, or plastering, interior and exterior walls with a local derivative of plaster. Stucco also became part of the Southwest's architectural palette and can be found on the exterior of many contemporary buildings as well.
