National Gypsum has licensed South American construction company PanelRock, S.A., to produce and distribute the manufacturer’s ProForm ready mix joint treatment at its new plant in Cartagena, Colombia. PanelRock is licensed to sell the ProForm ready mix in Colombia, Venezuela, Puerto Rico, Curacao, Central America, and the Caribbean. “This 10-year agreement will allow National Gypsum to better compete in the growing Latin American market,” said John Ferretti, general manager for Interior Finishing Products. Under the licensing agreement, National Gypsum will supply the proprietary dry ingredients for its ProForm products. PanelRock will then produce ProForm in its Cartagena plant. It will be processed and sold under the Charlotte-based manufacturer’s ProForm trademark. The first container-load of the ProForm dry ingredients has been shipped from National Gypsum’s plant in Atlanta to Cartagena. For more than 16 years, PanelRock has been one of the largest entities in the Colombian construction industry.
