Selleys is an Australian company which produces household DIY and cleaning products as well as adhesives and sealants for the trade market. It is widely known for recent products such as Selleys Liquid Nails, Selleys No More Gaps and Selleys All Clear. Selleys Metallic Cement and Selleys UniFix preceded these products. Many of their products are sold throughout Asia and have become extremely popular in households Australia-wide due to their durability and availability.

Martin Selley established the Selleys Chemical Company after he left Germany for Australia in 1939. He had a formula for wood Putty which he and his wife mixed up in the laundry sink and sold to hardware stores and glaziers. He then launched two more products, Selleys Metallic Cement, and Selleys Unifix, which are still available today, as is the Wood Putty. The huge success of the company was slow to arrive, but as DIY became more popular, the Selleys product range expanded to meet demands, and eventually Selleys were selling adhesives, sealants and much more, and the Selley's slogan, "If it's Selleys, it works," ( which was conceived in the lounge room of Doug Stewart at 45 Goodwin Tce. Moorooka, Brisbane) became recognised by most people.Doug Stewart (Chief Consultant and Rep for Selleys in Queensland from 1959 to 1977) was sent to Sydney to oversee the use of Selleys Unifix to secure the tiles on the Sails of the Sydney Opera House during construction.

Selleys is now a subsidiary of Dulux Group, an Australian listed company on the S&P/ASX 200.
