Primer Finish

A primer finish applied to cast iron radiators plays a crucial role as a protective base coat during the manufacturing process. A primer finish is not intended to be the final coating but rather serves as the fundamental layer upon which additional paint can adhere effectively.

Ensuring compatibility with water-based paints this can be achieved by using the recommended primer as suggested by the paint manufacturer and Arroll's expert finishing team.

Occasionally, there may be instances where a primed radiator might develop oxide (rust) when exposed to air or moisture. This situation typically arises because the radiator only has a preliminary thin coat of primer and lacks the protective sealing provided by an appropriate metal paint.

Although it's not a common practice, some individuals opt to leave radiators in their primer finishes even after installation. As a standard feature, Arroll radiators are supplied with a black primer finish, giving you the option to maintain this look if desired.

Specialised Finishes

Arroll's in house team of highly skilled metal polishers and detailers are dedicated to their craft. They expertly polish every section, enhancing raised or ornate features with a variety of colors. Whether you seek an aged effect or a highlight burnish finish, discover our options below.

RAL Colour Aged

When used on intricately designed radiators, it really enhances the patterns and details. While it's most pronounced on ornate or patterned radiators, it still imparts a subtle yet stylish effect on simpler, plainer styles.

The final result is achieved by allowing the base coat to dry thoroughly, a secondary colour is applied over it. During this phase, two coats of paint are delicately removed from specific areas while the paint is still wet, creating a two-tone effect. The outcome showcases the dominant presence of the base colour, with deeper crevices highlighting hints of the secondary colour.



Highlighted Burnished Finishes

Arroll offer three burnish finishes, Black & Gold Burnish / Black & Silver Burnish / Black & Copper Burnish.

The Gold, Silver or Copper burnish is placed on any raised radiators areas with the base colour being black. This especially popular on any patterned radiators with any raised sections, such as the orante scroll work found on a Art Nouveau or Daisy, polished to a bright finish.

This distinctive finish is attained by initially assembling and painting the radiator. Subsequently, it proceeds to our grinding and fettling department, where we expertly enhance the pattern while maintaining the rest of the radiator in a striking black hue

This is then lacquered to preserve this effect without needing to oil/maintain it. The burnish highlights the raised sections with gold, siler or copper paint. Please see examples below:



Polished Finishes

Arroll has a dedicated highly trained team of metal polishers and detailers. From polishing each section to highlighting raised or ornate features in various colours, the Arroll team can really transform each radiator to give that Full Polish, Rustic Polish or Lacquered Natural Brass Finish please check them out below.

Full Polish

A polished finish means that rather than having a painted finish the radiator is polished back to bare metal. It is a clever way to add contrast to finely detailed radiators by accentuating raised sections with a brighter polish. 

Each section is sandblasted to remove any surface primers then fettled and individually hand polished by Arroll's experienced polishers. The radiator is then built, tested, and lacquered.

Arroll lacquer coat their polished radiators to prevent oxidisation. This means that it does not require regular oiling to maintain a rust free look.  However if rust spots do appear, light wire wool will remove the spots followed by touch-up lacquer available from Arroll on request. Polished finishes are not suitable for Humid atmospheres such as Bathrooms. It is also inadvisable to place wet or damp clothes on polished radiators.



Rustic Polish

For Arroll's Rustic Polish finish the radiators go through a meticulous process, including each section getting a black primer coating, then skilled fettling for a smooth surface, and hand polishing to a rustic finish by Arroll's experienced polishers. They are assembled, tested, and lacquered for protection, but rust spots may still appear due to cast iron's nature and varying environments. Keep in mind that polished finishes aren't ideal for humid spaces like bathrooms, and avoid placing wet clothes directly on them to maintain their appearance.



Lacquered Natural Brass

Lacqured Natural Brass is beautiful on ornate, school house or traditional radiator styles, this brass finish adds a little something extra. To give it an aged look, after the radiator is painted and dried, it is then overpainted in the darker colour.

While wet, 2 coats of paint are removed in specific areas to create a stunning two tone look. This unique finish is then sealed with a coat of lacquer to protect the paint and gives an impressive gloss finish. This is particularly effective on ornate radiators to emphasize the pattern, discover our options below.
