Plasterers & Cement Masons Apprenticeship – OPCMIA Local 599 (Wisconsin)

Program Information

The Operative Plasterers and Cement Masons International Association (OPCMIA) represents one of the oldest and most respected skilled trades organizations in North America. Through its affiliated locals, including OPCMIA Local 599 in Wisconsin, the union provides structured apprenticeship training for individuals pursuing careers as cement masons and plasterers. This apprenticeship is designed to develop highly skilled craftworkers who specialize in concrete placement, finishing, and plaster applications used across commercial, industrial, residential, and infrastructure construction projects.

Cement masons work with crews to pour, level, smooth, and finish concrete surfaces such as floors, sidewalks, curbs, foundations, walls, and highways. Apprentices learn essential techniques including rodding, edging, jointing, screeding, sawing joints, rubbing, patching, and surface repair. This work requires precision, physical stamina, and attention to detail, as concrete is an unforgiving material that demands skill and timing. Many projects take place outdoors, exposing workers to varying weather conditions while contributing to highly visible, permanent structures.

Plasterers specialize in wall and ceiling systems, focusing on surface preparation and finishing techniques that provide durability, fire resistance, acoustics, and decorative appeal. Apprentices learn interior and exterior plastering, texture finishes, plaster veneers, coatings, and specialty applications such as EIFS systems, fireproofing, historical restoration, and decorative finishes. Plaster remains a critical building material in modern construction, combining longevity with architectural versatility.

The OPCMIA apprenticeship emphasizes hands-on learning supported by paid classroom instruction. Apprentices earn wages that increase progressively as skills are demonstrated and experience is gained. The first six months serve as a probationary period, allowing apprentices to demonstrate commitment and aptitude for the trade. Union membership provides long-term career stability, strong wage potential, and access to benefits while preserving the traditions of craftsmanship that have defined the trade for more than 150 years.
