Crossfield Products

A chemist named Jack Crossfield developed a rubberised cement compound for floor and decking underlayments in the late 1930s — possibly the first deployment of what is now called Polymer Modified Concrete. A Los Angeles business group bought the company from him, trademarked the name *Dex-O-Tex* (a contraction of *Decks of Latex*), and incorporated Crossfield Products Corporation in 1938. When the Second World War put natural rubber on allocation a few years later, the firm pivoted to synthetic-rubber polymer modification and supplied its decking compound to the United States Navy and to the famous transatlantic liners of the period: the Queen Mary, the SS America, the Queen Elizabeth, and, on both interior and exterior decks, the SS United States.

The firm manufactures construction coatings, overlays, and fluid-applied flooring materials — polymer-modified concrete underlayments, terrazzo systems, deck waterproofing, marine deck coverings, and the chemical-resistant industrial coatings used in clean-rooms, food-processing facilities, and the more demanding categories of public-sector construction. The catalogue spans three principal brands: Dex-O-Tex (architectural and industrial), Miracote (waterproofing and concrete restoration), and Dex-O-Tex Marine (military and commercial vessels). Manufacturing happens at three plants — two in Southern California, one in New Jersey — and Crossfield’s products are specified into projects on every inhabited continent.

What distinguishes Crossfield Products in its sector is the combination of category-original chemistry and continuity. The firm was a pioneer of polymer-modified concrete; it has remained privately held since founding and has stayed in the same family of brands for the better part of nine decades. Most chemical-coatings manufacturers of comparable scale and longevity have either been absorbed into the global coatings conglomerates or have narrowed onto a single specialty; Crossfield has held its breadth and held its independence.

The practice has worked with Crossfield Products at the Rancho Dominguez plant on Lean process implementation across operations.
