Painting Radiators

Radiator Paint

When painting a room, radiators are often forgotten and painted white out of habit.

Considering radiator paint in your colour scheme will help you to create a coordinated finish. Highlight radiators with a contrasting colour or paint them in a complementary shade.

Where possible, we would advise painting your radiator before it is fitted; this will allow you to paint all surfaces. However if this isn’t possible, simply paint the radiator in situ. Make sure to drain the radiator and ensure it is turned off during the application process.

How to Paint a Radiator

Prepare the Surface

Before beginning the project, place protective dust sheets under the radiator to protect your flooring.

For previously painted radiators, smooth the surface with a medium grade sandpaper. This will create a slightly rough surface that the paint will adhere to. Following this, thoroughly clean your radiator surface with a sponge and sugar soap before rinsing and allowing to dry.

Prime the Metalwork

It is vital to prime your radiator, to prevent staining and rust spots that could alter your chosen colour.

Ensure that you have properly stirred the paint prior to commencing painting. Using an angled paint brush, apply two coats of Intelligent Primer Undercoat. Your metal primer should be tinted to your chosen top coat shade to ensure full depth of colour.

Paint the Radiator

Leave the undercoat to dry for 4 hours before applying the first coat of paint in your chosen shade. We recommend using Intelligent Eggshell as an easy-to-use, quick-drying radiator paint.

(Note: This type of paint can be thinned as applied as a spray paint if desired. See the detailed Product Data Sheets for further guidance.)

Allow 4 hours for the first coat to dry before applying the second and final coat. For deep hues, you may need to apply an extra coat for the perfect finish. Allow the paint to dry fully for 48 hours before turning on the radiator.
