Requirements to become a Plasterer or Cement Masons contractor are straightforward and uncomplicated. The contractor must become signatory to either a Building Trades or statewide Heavy and Highway Agreement depending on which part of the industry they perform work in. These Agreements stipulate that wages consistent with prevailing wage will be paid and the members’ benefits will be paid in a timely manner. All working rules and conditions are clearly spelled out in these Agreements. There is no upfront cost to become a signatory contractor. The Agreements are negotiated between the Union and our Association partners. The Building Trades Agreement is negotiated with the Construction Employer’s Association. These Agreements covers all aspects of the plastering and commercial concrete industry. The Heavy Highway Agreement is negotiated on a statewide level between all of the Cement Mason Local Unions in the State of Ohio and the Ohio Contractors Association.
