In short
People ask us this every few weeks, usually after seeing a cream Aga they wish were black, or a chipped lid they wish were whole. The honest answer is that you can paint an Aga, in the sense that paint will go on, but you will not be happy with it for long, and undoing it is more expensive than doing it properly in the first place. Below is what an Aga finish is, why paint fails on it, what you can safely do yourself, and what a professional re-enamel involves and costs.
What an Aga finish is
The outside of an Aga is cast iron coated in vitreous enamel: powdered glass fused to the metal in a kiln at temperatures far beyond anything a kitchen sees. That is why a well-kept Aga from the 1950s still shines. The enamel is hard, glossy, non-porous and bonded to the iron. It resists heat, fat, steam and years of pans being dragged across it.
It is also, for the same reason, a terrible surface to paint. Paint needs something to grip. Glass gives it nothing.
What happens when you paint an Aga
We have seen the results of most of the ways people try this, and they go the same way:
- Edges and corners first. The paint on lid rims, door edges and the front corners wears through within weeks, because that is where hands and pans touch.
- The top plate. The hotplate surrounds and the top plate run hot. Stove paints are made for stoves, where nobody is sliding a kettle across the surface, and they mark and dull on an Aga top.
- Around the doors. Door frames get wiped daily. Paint rubs thin and the old colour shows through as a halo.
- Keying makes it worse, not better. Some guides tell you to sand or etch the enamel so the paint grips. That scratches the glass, which cannot be polished back, and when the paint fails you are left with a dull, scored enamel surface that only the kiln can fix.
- Nothing can be undone. Paint cannot be removed from enamel without stripping, and stripping takes the enamel with it. A painted Aga is a cooker that needs re-enamelling, whether it needed it before or not.
The same applies to the kits and sprays sold for barbecues, radiators and car exhausts. They are made for bare metal, not for glass.
What you can safely do yourself
A tired finish
A great deal of what looks like faded enamel is a film of cooked-on grease. A proper clean with an enamel cleaner and a soft cloth, done section by section while the cooker is warm rather than hot, often brings back a shine that owners thought was gone. Never use scourers, abrasive creams or oven sprays on the enamel: they scratch the glass or leave residue near food.
A small chip
A chip the size of a fingernail on a lid or a door can be filled with a cold enamel touch-up repair, available in the standard Aga colours. Clean the chip, let the cooker go cold, fill in thin layers, and leave it to cure. It will not match exactly and it will not survive on the top plate, but it hides the mark and, more usefully, keeps moisture off the cast iron so rust does not spread under the enamel around it. Treat it as a stop-gap until the cooker is next refurbished.
Doors and lids separately
Because an Aga comes apart, the parts that take the most wear can be re-enamelled on their own. Our re-enamelling cost page prices the top plate and lids, the front and doors, and the full set separately, so a cooker with a tired lid and a perfect front only pays for the lid.
What re-enamelling involves
Our Aga re-enamelling service does what the factory did:
- The panels are collected and taken to the workshop.
- The old enamel is stripped from the cast iron completely.
- New vitreous enamel is applied in the colour you choose.
- The parts are kiln-fired, so the new finish is fused to the metal.
- They are refitted, and the cooker is checked and relit.
Chips, scratches and dull patches go with the old enamel. The result is the finish the cooker was built with, in whichever colour you want, and it lasts for decades rather than months.
What it costs
| Parts | 2-oven | 3-oven | 4-oven |
|---|---|---|---|
| Top plate and lids | £2,000 | £2,000 | £2,280 |
| Front and doors | £2,750 | £2,880 | £3,350 |
| Front, doors, top plate and lids | £3,800 | £4,000 | £4,800 |
A change of colour is included. Most owners who ask us about painting are really asking about a change of colour, and this is the way to get one.
When re-enamelling is part of something bigger
If the cooker has more wrong with it than its finish, a tired burner, a cold simmering oven, a lid that no longer seals, then a full Aga refurbishment is the better job: everything stripped, rebuilt and re-enamelled together, so the cooker comes back as good as new in every respect. For a cooker beyond that, our reconditioned Agas are rebuilt and re-enamelled the same way, with the colour of your choice.
Why people want to paint, and the real fix for each
- The wrong colour. The cream Aga that came with the house would look better in black, or the black one in blue. The fix is a colour change in the kiln, included in re-enamelling, on the front and doors alone if the top is fine.
- Chips on the lids. The insulating lids take the most knocks and the worst of the chips. The lids can be re-enamelled on their own, and a touch-up repair holds a small chip until then.
- A dull, streaky front. Nine times out of ten this is grease and cleaning residue, not worn enamel. Clean it properly before you decide anything.
- Rust showing in a chip. Fill it now with a cold repair so the rust stops spreading under the enamel, and plan to re-enamel the panel before it lifts.
- A new kitchen. When the units, the floor and the tiles have all changed, the Aga is the one thing you cannot swap for a new finish from a catalogue. Re-enamelling in a colour that suits the new kitchen is cheaper than a new cooker and keeps the Aga you know.
Before you decide
- Clean it first. An hour with an enamel cleaner tells you how much of the problem is the finish and how much is the film on top of it.
- Look at it cold. Chips and scratches show more on a cold cooker in daylight. Photograph each panel so you know what you are dealing with.
- Price the panels, not the cooker. A lid or a door can be done on its own.
- Ask about everything else at the same time. If the cooker is due a service or a new burner, doing it while the panels are off saves a second visit.
- Do not paint it. Whatever you decide, a tin of stove paint is the one option that makes every other option dearer.
Frequently asked questions
Can you paint an Aga?
Physically, yes: high-temperature stove paint will go on. But an Aga’s finish is vitreous enamel, which is glass fused to the cast iron in a kiln. Paint sits on top of that glass rather than bonding to it, so it chips at the edges, scratches under pans, marks around the door handles and dulls on the hot top plate within months. It also cannot be removed without taking the enamel back to bare metal, so a painted Aga has to be re-enamelled professionally to put right.
What is the difference between painting and re-enamelling an Aga?
Paint is a coating applied cold on top of the existing surface. Re-enamelling strips the old enamel off the cast iron panels, applies new vitreous enamel in the colour you choose, and fires it in a kiln so the finish is fused to the metal. The result is the same glossy, hardwearing surface the cooker had when it was new, and it lasts for decades.
How much does it cost to re-enamel an Aga?
Our prices start at £2,000 for the top plate and lids of a 2-oven or 3-oven Aga and £2,280 for a 4-oven. The front and doors are £2,750 for a 2-oven, £2,880 for a 3-oven and £3,350 for a 4-oven. The full set, front, doors, top plate and lids, is £3,800, £4,000 and £4,800 respectively. The parts are collected and treated in the workshop.
Can I change the colour of my Aga?
Yes. A change of colour is included in our standard re-enamelling service, from classic cream and black to modern shades. Changing colour is the most common reason owners come to us, and it is far better done in the kiln than with a tin of paint.
How do I repair a chip in Aga enamel?
A small chip on a lid or door can be filled with a cold enamel touch-up repair, which hides the mark and keeps moisture off the cast iron underneath. It will not match perfectly and it will not survive on the top plate. For anything more than the odd small chip, or for a finish that is dull all over, re-enamelling is the proper repair.
Will painting my Aga affect its value?
Yes, downwards. A reconditioned Aga sells on its enamel; buyers and dealers look at the finish first. A painted cooker has to be stripped and re-enamelled before it can be sold on, so painting takes more off the value than the cost of the paint saves.
