Painting Metal Railings and Ironwork in Hampstead NW3

Victorian cast and wrought iron railings, basement-area steps, and balcony structures are a defining feature of Hampstead NW3 period terraces and semis. Maintaining them correctly — preventing rust, maintaining the paint finish, and preserving the original ironwork profiles — is a specialist skill.

Rust Treatment and Preparation

Any surface rust must be ground back to clean metal with an angle grinder before repainting. Surface contamination (old loose paint, dirt, road grime) is removed with wire brushing and degreasing. For severely rusted sections, we use a phosphoric acid rust converter before priming — this chemically converts remaining iron oxide into a stable compound that can be painted over.

The Correct Paint System for NW3 Ironwork

For exterior ironwork, we apply: red oxide primer (or zinc phosphate primer for enhanced protection on badly rusted sections); one coat of undercoat; two coats of oil-based or high-quality water-based gloss. The total system builds to approximately 250 microns — significantly more film than a single coat of bitumen or topcoat, providing substantially better protection.

Colour Matching Period Ironwork

Original Victorian railings in Hampstead NW3 were invariably painted black — and black remains the appropriate and most attractive choice for period ironwork. Where councils have painted streetside railings in other colours, we can match these precisely for adjoining property railings.
