Masons lay and bind building materials, such as brick, structural tile, concrete block, cinder block, glass block, and terra-cotta block, with mortar and other substances to construct or repair walls, partitions, arches, sewers, and other structures.

The most desired qualities in a (brick) mason are dependability and a strong work ethic. Knowledge of basic math (including measurement, volume, mixing proportions, plane geometry) and mechanical drawing is important in this trade. Specific skills include: interpret blueprints and drawings to determine specifications; calculate the materials required; lay and align bricks, blocks, or tiles to build or repair structures; move or lift heavy objects; read blue prints and technical drawings.
