MEDINA, Ohio — RPM International announced that its Rust-Oleum group has acquired Siamons International, provider of the Concrobium brand of non-toxic specialty mould cleaners. Ontario-based Siamons has annual net sales of approximately $20 million. Terms of the transaction, which is expected to impact earnings within one year, were not disclosed.
“The Concrobium brand is an excellent strategic fit that will expand Rust-Oleum’s specialty cleaning product portfolio, complementing its existing Krud Kutter, Mean Green, Roto-Rooter, Whink, Jomax and Moldex brands and resulting in significant cost synergies and enhanced supply chain efficiencies,” said Frank C.
