MASTERCHEM

Mr. Caldwell introduced the KILZ® brand in 1974 at the National Paint Show. His company's "Masterchem" name was created to promote the flagship product, KILZ primer, nationally. Soon afterward, other specialty primers were added to the product line. Masterchem was a subsidiary of Caldwell Paint Manufacturing Company, Inc... In 1961, Mr. Caldwell moved his manufacturing process to a building on Trenton Avenue in North St. Louis County and employed two people to mix 400-gallon batches of paint. Over the years, his company continued to grow and required larger and larger facilities, eventually moving to Kirkwood, Mo. in a 14,000 square foot facility.
