Cement Masons & Concrete Finishers Salary in Missouri

Cement masons and concrete finishers in Missouri earn a median salary of $57,050 annually, or $27.43 per hour – slightly above the national median of $54,660. With Missouri's lower cost of living (89.2% of national average), this translates to strong purchasing power equivalent to nearly $64,000 nationally. Entry-level workers start around $39,530, while experienced finishers can earn $85,190 or more. Pay varies significantly based on experience, with the middle 50% earning between $47,000-$72,790. Union membership through OPCMIA locals typically boosts wages and benefits. Metropolitan areas like St. Louis and Kansas City generally offer higher pay due to larger commercial projects and higher demand. Specialty work like decorative concrete, industrial flooring, or highway construction commands premium rates. The construction boom and infrastructure investments create steady demand, though work can be seasonal and weather-dependent. Career advancement opportunities include becoming a crew leader, starting your own concrete business, or specializing in high-end architectural concrete work.

Most Missouri cement masons enter through apprenticeships or on-the-job training, with over 50% having no formal education beyond high school. The Operative Plasterers' and Cement Masons' International Association (OPCMIA) operates apprenticeship programs throughout Missouri, including strong locals in St. Louis, Kansas City, and Springfield. These programs typically run 2-4 years, combining 144 hours of classroom instruction annually with 2,000+ hours of hands-on training. Apprentices start earning 40-50% of journeyman wages ($11-14/hour) and receive raises every six months, reaching full scale upon completion. The Missouri Department of Commerce and Insurance oversees apprenticeship standards but doesn't require state licensing for cement masons. However, some municipalities may require permits for certain projects. Key training covers concrete mixing, finishing techniques, form setting, joint cutting, and safety protocols. Alternative paths include construction technology programs at community colleges like St. Louis Community College or Missouri State Technical College, though most employers prefer learning through apprenticeships. Union programs often provide better benefits, structured pay increases, and connections to major commercial projects throughout the state.

The $45,660 gap between the 10th percentile ($39,530) and 90th percentile ($85,190) reflects significant earning potential through experience and specialization. Entry-level workers typically earn in the bottom quartile, handling basic tasks like screeding and floating under supervision. The median earner at $57,050 represents journeyman-level masons with 3-5 years experience doing independent finish work. Top earners ($72,790+) are typically crew leaders, specialized finishers doing decorative or industrial work, or those working union jobs on major commercial projects. Geographic location within Missouri matters significantly – workers in St. Louis and Kansas City metro areas generally earn 15-25% more than rural areas due to larger projects and union presence. Union membership is a key differentiator, with OPCMIA members often earning $5-10/hour more plus comprehensive benefits. Specialty skills like stamped concrete, polished concrete, or high-rise construction can push experienced finishers into the top 10% of earners.
