RPM International Inc. through its Rust-Oleum Group has acquired Synta Inc., a producer and marketer of exterior wood deck and concrete restoration systems. Based in Clarkston, GA, Synta's annual sales are anticipated to exceed $40 million in the first year. Synta's unique Deck Restore and Concrete Restore brand products offer consumers the opportunity to extend the life of weathered outdoor wooden decks and concrete surfaces beyond the performance of conventional stains, paints and sealers the company said. They are widely available at nationwide home centers and other home improvement retailers. Additionally, Synta offers a line of arts and craft coatings under the Anita's brand, and a recently introduced line of specialty coatings under the MyColor by Pantone brand. Randy Moore, Synta chief executive, will continue to lead the organization, which will operate as a stand-alone business within Rust-Oleum's Consumer Business Group, and Tom Curtis, Synta founder, will continue in a consulting capacity.
