    A Concrete Flatwork Finisher is a craftsman who has demonstrated knowledge about and the ability to place, consolidate, finish, edge, joint, cure and protect concrete flatwork.

    • Possess 4,500 hours of actual on-the-job finishing* experience (approximately three years of regular full-time work).

    The two-hour written examination is closed-book and consists of approximately 50 multiple-choice questions. The passing grade for the written examination is 70%.

    *Finishing experience includes concrete placement, consolidation, jointing, curing and protection, finishing, form setting, prep work, rubbing, patching, and saw cutting. Verification of the work experience by the candidate's employer(s) is required.

    **During the performance examination, each examinee must place, consolidate, finish, edge, joint, begin curing, and provide initial protection for a concrete slab. The examiner will observe and evaluate the techniques used and record passing or failing grades on the various individual procedures. A passing grade is defined as "no significant variation from proper procedure and no more than two variations from proper technique in the use of the tools."

Individuals with Flatwork Technician certification can upgrade to full Flatwork Finisher status upon submittal and approval of sufficient work experience or successful completion of the ACI performance evaluation.
