What Stonhard does

Stonhard, founded in 1922 and headquartered in Maple Shade, New Jersey, manufactures and installs seamless resinous flooring, wall, and lining systems for commercial and industrial facilities. The company's core technology spans proprietary formulations of epoxy, polyurethane, methyl methacrylate (MMA), and novolac chemistries organized into product families including Stonclad (high-strength industrial mortars), Stonshield (textured and slip-resistant systems), Stontec (decorative flake finishes), Stonblend (decorative mortars with recycled glass), Stonres (acoustic and resilient flooring), Stonchem (chemical-resistant linings), and the Liquid Elements luxury collection. These systems are designed for regulated, high-wear environments—seamless surfaces eliminate joints that harbor bacteria, while chemical-, impact-, thermal-shock-, and slip-resistant properties address demanding end-use conditions.

Stonhard operates a single-source turnkey business model: it manufactures its products in owned facilities and deploys its own direct installation crews globally, providing one point of contact from specification through warranty. Distribution is 100% direct enterprise field sales with project-based custom quoting; no intermediaries, dealers, or subscription revenue exist. The company operates in more than 90 countries with localized installation teams and serves Food & Beverage processing, Pharmaceutical/Biotechnology, Manufacturing/Industrial, Healthcare, Aerospace/Defense, Commercial, Education, and Government verticals, where HACCP International, ISO 9001, EPD, HPD, and CDPH/EHLB certifications function as purchase prerequisites. An exclusive partnership with Blücher extends the offering into integrated hygienic drain systems for sanitary environments.

The company is a subsidiary of RPM International Inc. (NYSE: RPM), a publicly traded diversified specialty coatings and building products conglomerate. Strategic activity has historically included acquisitions of installation and facilities-services players (Ascoat Contracting in 2009, National Building Facilities Services in 2005), and product portfolio expansion through Liquid Elements, the MMA Xpress rapid-install family, and hygienic wall solutions. Headcount is reported in the 1,001–5,000 range; specific revenue is not publicly disclosed.
