With correct preparation, Earthborn Claypaint, Lifestyle and Eggshell No.17 can be used on metal including radiators. Our paints don’t like being applied to very shiny, non-porous surfaces so we recommend using an appropriate metal primer as per the manufacturer’s instructions, and always testing an inconspicuous area first. Make sure the radiator is switched off during painting and drying stages.
Claypaint will provide an ultra-matt finish but is not recommended for heavy-use items, whereas Earthborn Eggshell No.17 will provide a durable subtle sheen and is available in the same range of colours. When applying Earthborn Eggshell No.17 we would suggest building up the finish in layers and sanding lightly in between dried coats.
