In 2007 Stef decided to pursue her dream of designing a clothing line. Wet Cement started without much money, but with a big idea, a 500-watt halogen bulb, a darkroom built in her hallway, and a bathtub for making screens.. Within four years Wet Cement became a multi-million dollar company. Wet Cement retailed at Saks Fifth Avenue, Neiman Marcus, Bloomingdales, and Nordstrom's.
Stef worked with Warner Brothers to create a joint line called Cement Power, which brought Superman and other DC Comics action heroes to a high end retail market.
