Repainting painted kitchen cupboards

Your doors are already painted. How to tell what's on them, when to strip and when to paint over, water-based over oil, colour changes, guarantees, and lead.

Updated 28 October 2026 · The Kitchen Resprayer

The short answer

Find out what's on the doors first: a meths rub test separates water-based from oil-based paint, and factory finishes need a test door.

Sound paint gets degreased, keyed, patch-primed and painted; peeling areas come back to a feathered edge; a failed respray goes back to the base. Check your guarantee before you sand.

What's on your doors now

Old finish	How to tell	What it means
Hand-painted, water-based	Paint comes off on a cloth with methylated spirits	Easiest to repaint: degrease, key, patch prime
Hand-painted, oil-based	Nothing comes off with meths; whites may have yellowed in dim cupboards	Needs a thorough key and an adhesion or bonding primer under water-based paint
Factory catalysed or polyurethane	A hard, even factory finish; the rub test tells you little	Key all over, adhesion primer, test one door
Factory nitrocellulose lacquer	Ask the maker if you can; otherwise test a hidden patch	One maker's water-based paint and primer sheets say they're not suitable over it: test
Painted vinyl	Paint over a wrap that folds round the edge	A vinyl job: see laminate and vinyl

The rub test is from The Decorators Forum and Splat Decorating Supplies. Use a hidden patch and a cloth of a different colour to the paint.

Factory finishes are tougher than they look. Masterclass Kitchens says its painted doors have an acrylic primer and a polyurethane topcoat; DIY Kitchens mixes its door paint with a solvent-based catalyst. One UK decorator also notes very little sticks to oil-based gloss "because the surface is so smooth and shiny".

Strip or paint over

What you find	What to do
Sound, well stuck	Degrease, light sand, patch prime bare or filled spots, paint
Peeling or blistering in places	Take those areas back and feather the edges until you can't feel the step
Lifting across the door	Back to the base, or a professional strip
A failed previous respray	Back to the base: the same failure repeats over a bad layer
A factory finish	Test one door and wait for the primer's adhesion cure before doing the rest

Farrow & Ball's primer sheet: flaking or peeling can occur if you paint over weak paint layers. Ultimate Decor: a few chips can be flatted and resprayed; broad adhesion failure usually means stripping back.

A quick check of your own: press tape firmly onto a keyed, hidden patch and pull it off. If old paint comes with it, it isn't sound. That matters because of what happened in one UK BuildHub thread: factory-painted doors were resprayed after a 180 grit key and a coloured primer, and at three months low-tack tape took "huge patches" off. Members thought the primer "has just sat on top of the factory coating, instead of bonding to it", and the advice was to experiment on a single door.

Water-based paint over oil-based

Prepare thoroughly

One trade paint sheet: going water-based over solvent-based paint, "very thorough surface preparation will be necessary".

Kill the shine, then prime

UK decorators and one retailer say degrease, sand off the shine, then an adhesion or bonding primer, one or two coats depending on the old colour.

Wait over fresh oil paint

One primer maker says allow at least 14 days before going over solvent-based coatings.

Give it time to grip

One water-based paint maker says over an oil-based primer final adhesion takes two weeks: keep masking tape off.

Sand anyway

One shellac primer claims it grips gloss without scuff sanding; Which?'s traders say painting without sanding won't last.

Water-based paint also won't hold over grease, so the degreasing step on the how-to page matters more than usual on old kitchen paint. Choosing the new paint: paint types compared.

Changing colour

Dark to light

Which? says use more primer and go back to a neutral base so the old colour doesn't show through.

Tint the primer

One maker sells its primer in four tones to suit the topcoat; Valspar UK says a tinted primer helps with dramatic changes; shellac and bond-coat primers can be tinted too.

Expect extra coats

A trade paint sheet says a significant colour change may need additional coats.

Old yellowed paint

An aged oil-based white can ghost through a light new colour unless it is primed.

Future chips

A chip shows whatever is underneath, so a big change makes every later chip more visible. See colours and wear.

Touch in, or repaint?

Mayfair Kitchens says minor marks can usually be touched up rather than a door replaced, if you kept the colour reference, the sheen, a little of the original paint and the aftercare sheet. Its warning: "Applying too much paint makes a minor mark more visible rather than less", and if the area is bigger or the paint is no longer available, professional refinishing is usually better. DIY Kitchens sells touch-up paint but can't guarantee an exact match between orders.

Fine lines along the joints of painted timber doors are movement, not failure: Mayfair, Masterclass and DIY Kitchens all describe them. Repainting won't stop them coming back. More on touch-ups: how long a respray lasts.

Kitchen makers on repainting

Maker	What it says
Harvey Jones	Can be repainted "at any point in the future"; offers a refurbishment service for its kitchens
Mayfair Kitchens	Repainting is "one of the strongest arguments" for a painted finish; sound cabinetry can be painted again
Howdens	Guarantee excludes "alterations or repairs made by a third party"
DIY Kitchens	Warranty excludes alterations without its prior written approval; repainting "will depend on the door range"
Masterclass Kitchens	Its warranty page doesn't mention repainting

Each maker's own published wording, read 28 October 2026. If your doors are still in guarantee, ask the maker in writing before you sand them.

Respray guarantees have edges too: ColourHaus covers only the coating it applied, and Ultimate Decor says a third party painting over its work affects cover there. Under the Consumer Rights Act 2015, any service must still be done with reasonable care and skill.

Old paint and lead

UKHSA says paint could contain up to 50% lead until the 1950s, and added lead was banned in 1992 except in specialist paints. Sources give different cut-off dates (pre-1960s, mid-1960s, pre-1990), but kitchen units from the 1990s on are very unlikely to matter. Old built-in dressers, larders and painted joinery in an older house are where to stop and check.

Do	Don't
Leave sound paint and paint over it: "overcoating is the safest option"	Strip sound paint
Use wet abrasive paper or chemical stripper if it must come off	Dry sand or make dust
Keep children and pregnant women out of the room	Use a blowlamp, or a heat gun above 450C
Use a HEPA vacuum; bag and seal the debris	Burn the waste
Send a sample to a UKAS-accredited lab if unsure	Trust a negative home test kit

From the British Coatings Federation (HS 032), UKHSA and Cambridge City Council. UKHSA does not recommend chemical test kits; the BCF says a negative reading should not be relied on.

Sanding any paint makes dust. HSE asks trades to use at least an FFP3 mask and on-tool extraction; Which? says ventilate and wear a dust mask.

When to hand it over

It's a job for a sprayer if a previous respray has failed, a factory finish won't take paint on your test door, you're changing colour dramatically across a lot of doors, or there may be lead. Send us two photos and say what the doors are made of, and we'll price the respray from them. Weighing it up against new doors: respray, new doors or a new kitchen.

Common questions

Yes, if the old paint is sound. Degrease, sand to a key, take any peeling areas back and feather the edges, patch prime bare spots, then paint. Paint makers say paint over weak layers and it can flake or peel.

Rub a hidden patch with a cloth and a little methylated spirits. A UK decorator says if some paint wipes off it's water-based; if none comes off it's oil-based. A white that has yellowed inside a dim cupboard is another clue.

Yes, with preparation. One trade paint sheet says very thorough preparation is needed; UK decorators sand off the shine and use an adhesion or bonding primer first. Over fresh solvent paint, one primer maker says wait at least 14 days.

Not if it's sound and well stuck. Strip only where it's peeling, blistering or lifting across the door, or where a previous respray has failed. Never strip sound old paint that might contain lead: the British Coatings Federation says overcoating is the safest option.

It can. Howdens' guarantee excludes alterations by a third party and DIY Kitchens' excludes alterations without its written approval. Harvey Jones says its painted kitchens can be repainted at any time. Ask your maker in writing before you sand.

On kitchen units from the 1990s on, very unlikely. On older painted dressers, larders and joinery, possibly: UKHSA says paint could contain up to 50% lead until the 1950s. Don't dry sand it, and get a lab test rather than a home kit.
