Ronseal is the UK’s leading wood treatment, varnish and outdoor maintenance brand, launched in 1956 by Ronuk Limited in Sheffield and now owned by American paint giant Sherwin-Williams following a 1997 acquisition. Famous for the culturally iconic “Does exactly what it says on the tin” slogan created by advertising agency HHCL, the phrase entered everyday British language and was even quoted by Prime Minister David Cameron in Parliament in 2013. Manufactured at the expanded Chapeltown Sheffield facility following a £10 million Sherwin-Williams investment in 2022, Ronseal offers fence and shed protectors, decking stains, garden paint, weatherproof wood paint, wood varnishes, floor care, kitchen and bathroom treatments, and interior wall treatments. Products are consistent eBay UK and Amazon UK bestsellers with strong seasonal DIY demand backed by a confirmed Ronseal Trade professional channel.
