About the union: Organized in 1864, the Operative Plasterers’ and Cement Masons’ International Association has represented and trained plasterers and cement masons for the purpose of protecting and promoting the quality of their industry and the livelihood of their members. Plaster and concrete are ageless building materials that will not fall out of favor as long as there is a sufficient amount of workers who are skilled in the arts of installation and finishing. The OPCMIA is dedicated to the promotion of these materials, the recruitment and training of skilled craftsmen to meet the demand of our industry, and hold themselves responsible to this commitment for the future of their industry and the welfare of all those who earn their living in it.

About the Local: OPCMIA Local 300 serves the areas of Oakland, Sacramento, San Francisco, San Jose and many surrounding cities. Local 300 members apply various plaster products in a wide range of uses. The use of the varied forms of this product in the walls and ceiling industry requires a well trained and skilled workforce.

About the JATC: The Northern California Cement Masons JATC works with two local unions, OPCMIA local 300 and OPCMIA local 400. The training center trains cement mason apprentices the techniques needed to master their craft. In addition to apprentice training, the JATC also offers journey level courses so that journey workers can become more knowledgeable about the trade and the many evolving techniques.
