The job duties of a masonry apprentice involve working alongside masonry professionals on bricklaying, cement, and stone installations. During a masonry apprenticeship, you receive on-the-job training in bricklaying and related trade skills. Your responsibilities vary with the project, but they usually involve working with brick and other prefabricated stone materials. You learn to use equipment associated with the mason trade, and you also get training in the techniques used to build brick walls or construct other stone structures and installations. Apprentices work under the direct supervision of professional masons or bricklayers.
