How to Use

Turn the radiator off and allow it to cool fully before you start. Clean the surface to remove grease, dust and any flaking material, and mask off the wall, floor and any fittings you want to protect from overspray. Lightly key any existing gloss or satin finish with fine abrasive paper and wipe away the dust. Treat any rust spots and prime bare metal before spraying. Shake the can thoroughly, then apply in light, even sweeping passes from a distance of around 20 to 30cm, building up coverage with two or three thin coats rather than one heavy coat. Leave each coat to dry before applying the next, and allow the paint to cure fully, as set out in the technical specifications below, before switching the heating back on.

Frequently Asked Questions

Can you spray paint radiators?

Yes, a dedicated aerosol radiator enamel such as this Hammerite spray is designed specifically for the job. It gives an even, brush-mark-free finish and is particularly useful on radiators with grilles, columns or other awkward shapes that are fiddly to paint with a brush.

Can Hammerite metal paint be used on radiators?

This Hammerite Radiator Enamel is formulated specifically for radiators, giving a heat resistant finish that copes with repeated heating and cooling. It is a different product to Hammerite's general metal paints, so check the can and choose the radiator-specific enamel for the best results on a working radiator.

How do you paint a radiator with spray paint?

Turn the radiator off and let it cool, mask off the surrounding wall and floor, then clean and lightly key the surface. Shake the can well and apply in light, even passes from around 20 to 30cm away, building up two or three thin coats rather than one thick one, and leaving each coat to dry before the next.

How long does radiator spray paint take to dry?

This Hammerite radiator spray paint is typically touch dry within around 20 to 30 minutes, though this varies with room temperature and ventilation. Allow the paint to cure fully over several days before running the heating continuously.

What is the best radiator paint for a satin finish?

A dedicated radiator enamel such as this Hammerite satin spray is a reliable choice, giving a soft, low-sheen finish that is heat resistant and formulated to resist yellowing over time.

Do you need to prime a radiator before spraying?

Bare or rusty metal should be primed before you apply the topcoat, and any existing gloss or satin finish should be lightly abraded so the new paint keys in properly. Once prepared, this enamel can be applied directly without a separate primer coat in most cases.
