Ali Industries, which is commercially known as Gator Finishing Products, offers finishing products for power sanding, hand sanding, cutting and grinding, and floor sanding.
Its products are used on many surfaces, including wood, metal and paint.
They are sold under the brand names including Gator, Finish 1st and Zip Sander.
The company’s abrasive products are manufactured in the U.S. and distributed across North America through home improvement centers, mass merchandisers, hardware, paint and automotive supply stores.
Ali Industries will be a free-standing unit under RPM’s Rust-Oleum business.
The Ali brothers, Terry, Chris and Philip, will continue leading the business as part of Rust-Oleum.
“Ali Industries is an excellent synergistic fit within our Consumer Group because it broadens the segment’s surface preparation capabilities by adding abrasives to our lineup of patch, repair and cleaning products," said Frank C. Sullivan, RPM chairman and CEO. "Through this transaction, we plan to enhance Ali’s distribution base and enable the business to penetrate new markets."
