Sherwin-Williams Co. will close its Columbia Paint and Coatings manufacturing facility in Spokane, WA, eliminating 37 jobs. The paint-making plant on Haven Street opened 36 years ago. No retail paint stores are closing, the company said. Sherwin-Williams acquired Helena, MT-based Columbia Paint in 2007. The company operates 120 Sherwin-Williams stores and 42 Columbia Paint stores in six Northwest states. That includes four Columbia and six Sherwin-Williams stores in the Spokane area. The Spokane plant will close this summer because of “the challenges in the economy have created reduced demand and created excess capacity,” the company said.
