How to Use

Turn the radiator off and allow it to cool completely before starting. Clean the surface thoroughly to remove grease, dust and any flaking or loose material. If you are painting over an existing gloss or satin finish, key the surface lightly with fine abrasive paper and wipe away the dust so the new coat can key in properly. Treat any rust spots and let them dry out, and prime any bare metal before topcoating. Stir the paint well, then apply a thin, even coat with a brush, working in the direction of any ridges or panel lines. Leave to dry fully and apply a second coat if needed for full opacity and an even sheen. Allow the paint to cure fully, as stated in the technical specifications below, before turning the heating back on.

Frequently Asked Questions

Can you paint a radiator with gloss paint?

Yes, but it is best to use a paint made specifically for radiators, such as this 151 Coatings gloss enamel, rather than a standard wall gloss. Radiator paint is formulated to cope with the heat and expansion a radiator goes through, so it resists yellowing, cracking and flaking in a way ordinary gloss paint is not designed to.

How do you paint a radiator?

Turn the radiator off and let it cool fully, then clean the surface and lightly key any existing gloss with fine abrasive paper. Treat any rust, prime bare metal, then apply a thin even coat of radiator enamel with a brush. Leave to dry, apply a second coat if needed, and allow the paint to cure fully before switching the heating back on.

How long does radiator paint take to dry?

This radiator enamel is typically touch dry within a couple of hours, though this varies with room temperature and ventilation. Leave a full overnight period between coats, and allow several days for the paint to cure fully before running the heating continuously.

Can you paint radiator pipes?

Yes, radiator pipes can be painted with this enamel in the same way as the radiator itself. Clean and lightly abrade the pipe, treat any rust or bare metal, then apply thin, even coats with a small brush, taking care to avoid drips on tight bends and fittings.

What is the best paint for radiators?

A dedicated radiator enamel like this 151 Coatings gloss is a safer choice than standard household paint, as it is designed to withstand the heat and movement of a working radiator without yellowing or cracking. Choose a gloss, satin or matt finish to match the rest of your woodwork and trim.

Do you need special paint for radiators?

Yes, radiators reach temperatures that ordinary wall or wood paint is not designed for, so a heat resistant radiator enamel such as this one is recommended. It is formulated to keep its colour and finish through repeated heating and cooling cycles.
