Thirty-eight colours formulated for cast iron, selected from centuries of British architectural tradition. Each one ground in raw linseed oil — a finish that breathes, self-heals, and endures.
Why linseed oil
paint for cast iron?
Linseed oil paint is not a modern product. It has been used to protect and colour cast iron since the material first came into widespread architectural use in the early nineteenth century. It is the most historically authentic finish available for cast iron gutters, downpipes, hoppers, and associated ironwork on listed and historic buildings.
Unlike conventional alkyd or acrylic systems, linseed oil paint does not form a brittle surface film. It penetrates and bonds with the iron, remaining flexible as the metal expands and contracts. It self-heals at minor scratches, is fully vapour-permeable, and its natural pigments develop a patina over time that no manufactured paint can replicate.
For conservation officers, architects, and specifiers working on listed buildings, linseed oil paint is increasingly accepted — and in some cases preferred — by local planning authorities as the appropriate finish for external metalwork.
