Hello
Thank you for your recent enquiry.
AllCoat Exterior Water Based Paint is perfect for applying to radiators as this will provide a cleanable, durable, non-yellowing finish when applied by brush or roller in two coats at a coverage rate of approximately 10m2/L/coat, with a re-coat time of 1 hour. This is a self-priming paint, however if there is rust or other stain on the surface we recommend using a stain blocking primer such as Cover Stain (17114 & 17117) to hold these back. This should be applied in the same manner as the AllCoat but with a drying time of 2 hours.
The surface should be clean, sound and free of rust prior to applying the paints.
I hope this helps.
