Cement Masons

Operative Plasterers' and Cement Masons' International Association of the United States and Canada

OPCMIA members represent skilled plasterers, cement masons, shophands and associated members. Plasterers finish interior walls and ceilings of buildings, apply plaster on masonry, metal, wirelath or gypsum.

Bridges, canals, dams, reservoirs, roads and many other engineering feats would be impossible without the skills of OPCMIA cement masons. Cement masons are responsible for all concrete construction, including pouring and finishing of slabs, steps, wall tops, curbs and gutters, sidewalks, paving and other concrete construction.

OPCMIA members belong to 100 local unions, 4 district councils, 17 state conferences, and 3 provincial conferences.
