Hiring good finishers is key to a concrete contractor's success. But sometimes it's difficult to separate good finishers from those who can only talk about good finishing. Establish a hiring process for your company based on its qualifications for a good finisher. Each company has its own needs for a finisher, so determine the needs important to the type of work you do. When interviewing candidates: * Get references from other employers. * Use a hiring test to determine the applicant's knowledge of tools, materials, and practices. * Look for credentials. The American Concrete Institute certifies flatwork finishers. Does the applicant have a wallet card verifying certification? Also, ask applicants if they have attended any educational seminars or meetings on finishing techniques.
