Farrow & Ball Dead Flat Paint - Ammonite - No. 274

Yes, this paint is specifically formulated to be used on interior metal surfaces, including radiators.

The Dead Flat formula is based on alkyd resin, which offers the performance of oil-based paints with modern application and environmental benefits.

It features an ultra-matte finish with a sheen level of approximately 2%.

Ammonite is a balanced, understated grey. It does not lean aggressively warm or cool, making it a versatile neutral that adapts to its surroundings.

It is generally recommended to wait at least 4 hours between coats, depending on ambient temperature and humidity.

While it is durable, it is not specifically classified as a bathroom-grade moisture-resistant paint; avoid areas prone to direct water contact.

Ensure you are using a high-quality synthetic brush and avoid over-working the paint once it begins to tack up.

Confirm that the surface was properly cleaned, de-greased, and primed before application.

Apply a uniform second coat, ensuring you maintain a consistent wet edge during application to allow for proper leveling.
