RPM International Inc. announced it has signed a definitive agreement to acquire Star Brands Group, the U.K.-based parent company of The Pink Stuff, for its Rust-Oleum subsidiary. Star Brands will be integrated into RPM’s Consumer Group.

The Pink Stuff is known for its signature cleaning paste and rapid growth in the U.S., Europe, and other global markets. The acquisition adds to Rust-Oleum’s cleaners business, which includes Krud Kutter, Mean Green, Whink and Concrobium. It also strengthens RPM’s position in e-commerce, grocery and drug store channels.

The Pink Stuff generated approximately £150 million in net sales in calendar year 2024. Terms of the agreement were not disclosed. The transaction is expected to close in late Q4 of fiscal 2025 or early Q1 of fiscal 2026, subject to customary closing conditions.

Co-managing directors Henrik Pade and Tim North, along with the senior leadership team, are expected to remain with the business.
