Ronseal Outdoor Varnish

Ronseal is a storied British brand, founded in Sheffield, United Kingdom, in the mid-20th century. The company became a household name largely due to its highly successful 1990s advertising campaign featuring the slogan 'It does exactly what it says on the tin,' which has since entered the common British lexicon.

Historically, Ronseal was part of the Roncraft division of Sterling-Winthrop before being acquired by various entities. Today, the brand is owned by the American multinational Sherwin-Williams, headquartered in Cleveland, Ohio. Despite this American ownership, Ronseal maintains a strong British identity, with its primary manufacturing facilities and operations still based in Chapeltown, Sheffield, where it originated. This allows the brand to serve the UK and European home improvement markets with locally produced wood care, paints, and sealants.
