History

The Operative Plasterers’ and Cement Masons’ International Association of the United States and Canada , also known as the OP&CMIA, represents the members of one of the world’s oldest and most noble crafts. As early as man was building shelter for himself, there was plastering-first with mud or clay and later with a lime mixture much like that used today.

Young minorities were brought into the apprentice programs, opening the doors to jobs on construction sites across the nation.


As society grew and man undertook projects to control and improve his surrounding, cement masons became a vitally important part of the community. Bridges, canals, damns, roads, reservoirs and many other engineering feats would be impossible without the skills of OP&CMIA cement masons. Together, with the plasterers and fellow building tradesman, they have played a key role in shaping the world that surrounds us.

Fighting for legislation to improve the lives of minority citizens, the union joined with other building trade’s unions in an effort to increase minority employment in the construction crafts through apprenticeship training. Young minorities were brought into the apprentice programs, opening the doors to jobs on construction sites across the nation.

The Operative Plasterers’ and Cement Masons’ International Association continues to play a decisive role and work diligently on behalf of its members. Today the OP&CMIA is strong and building on its past, looks forward to the challenges of the new millennium. Over a hundred years after that first gathering of concerned craftsmen, this union continues to live by the principles upon which it was founded and which will continue to be its strength in the new millennium.
