Painting Wrought Iron Gates, Fences and Balustrades in Toorak
Walk along almost any street in Toorak, Armadale or Kooyong and the ironwork is part of the picture. Palisade fences with spear or fleur-de-lis tops, tall driveway gates, cast iron lace on Victorian verandahs, scrolled balcony balustrades on interwar mansions, and newer steel gates and pool fences on contemporary homes. It is often the first thing a visitor touches, and on a well-kept property it sets the tone for everything behind it.
It is also the part of the exterior that shows neglect fastest. Once rust starts bubbling under the paint, it spreads, and a fence that was a simple repaint a few years ago can become a repair job. Here is how we approach metalwork so the finish holds.
Know what you are painting
Not all metalwork is the same, and the preparation depends on what it is.
True wrought iron and cast iron are mostly found on older homes. Cast iron verandah lace and columns on Victorian houses, and some early gates and railings, are often original and may carry decades of paint layers. These pieces are brittle compared with steel, so they need careful handling, and old layers should be assumed to contain lead until tested.
Most fences and gates described as wrought iron are actually mild steel, fabricated to look traditional. Mild steel rusts readily once its coating is broken, especially at welds, joints and the bottom rails where water sits.
Galvanised steel, common on newer gates, pool fences and balustrades, has a zinc coating that resists rust but does not accept ordinary paint well. Painted directly with the wrong system, it can peel in sheets. Powder-coated metal is a different case again and needs its own preparation if it is to be overcoated.
Why paint fails on metal
Paint on metal fails at the weak points. Water collects on horizontal rails, at the base of posts, in the joints of scrollwork and around fixings. Once the coating cracks there, moisture reaches the steel, rust forms, and because rust takes up more space than the metal it came from, it pushes the paint off from behind. That is why you see blisters and flakes spreading outward from a small rust spot.
Garden sprinklers, hedges pressed against fences, soil and mulch built up around post bases, and pool water on balustrades all speed this up. So do the many coats a fence may have accumulated over the years, which can become thick and brittle and crack more easily.
Preparation is most of the job
A lasting repaint on metal comes down to how thoroughly the rust and loose paint are dealt with. Light surface rust can be removed by wire brushing and sanding back to sound, bright metal. Heavier rust needs mechanical cleaning, and badly corroded sections may need repair or replacement by a metal fabricator before painting. Painting over active rust, even with a product that claims to stop it, rarely lasts as long as removing it.
Once the surface is clean and dry, bare metal is primed promptly with an anti-corrosive primer suited to the metal, before fresh rust can form. Galvanised surfaces get a primer made for galvanising. Then the finish coats go on, usually in a durable exterior enamel or a system the manufacturer specifies for metal, with particular attention to edges, undersides and joints where the coating tends to be thinnest.
On older ironwork with lead in the paint layers, the preparation has to be done in a way that contains the dust and debris rather than spreading it across the garden and footpath.
Detail takes time
Ornamental ironwork is slow to paint well. Every bar, scroll and finial has four sides, and cast iron lace has hundreds of small openings. Brushwork is the most reliable way to get an even coat into all of that. It is one of the reasons a fence quote can surprise people: the linear metres may look modest, but the surface area and the time involved are far higher than a flat wall.
Colour choices
Traditional schemes on period homes often use deep greens, black, dark bronze or a deep red-brown on ironwork, picking up colours from the rest of the facade. On contemporary homes, black and charcoal are the most common choices. Dark colours on metal are generally fine, but they do get hot in summer sun, so a good quality exterior system matters. Our guide to choosing colours for grand period homes looks at how ironwork fits into a wider heritage scheme, and if the property is under a heritage overlay it is worth confirming any change of colour with the City of Stonnington first.
When to repaint
The best time to repaint metalwork is when you first see small rust spots or chips, not when the bottom rails are flaking. Catching it early keeps the job to preparation and repainting. Leaving it means more metal repair and a higher bill.
It is also worth folding metalwork into a larger job. If the house is being repainted, gates, fences and verandah lace can be done at the same time, often with access already in place. Garden structures such as pergolas and pool fences fit naturally alongside them, as our guide to painting pergolas and pool houses explains.
Getting a quote
Our Exterior House Repainting service includes gates, fences, balustrades and verandah ironwork, and on older properties it sits alongside our Heritage and Period-Home Repaints work for cast iron and original detail. We inspect the metalwork, identify what it is and how far the rust has gone, and give you a fixed written quote across Toorak, South Yarra, Armadale, Hawksburn and Kooyong.
