Grey internal doors

Grey internal doors arrive factory-painted rather than primed, so the colour is the finish and there is nothing to paint on site. The surface is more even than a brush can manage, but it cannot be touched up with a tin from a shop, and any edge you trim has to be repainted.

Grey has been the default alternative to white on British internal doors for about a decade, and it is the one colour people most often get subtly wrong. Not because grey is difficult, but because the word describes a range of colours with almost nothing in common beyond the absence of a strong hue.

There is also a decision underneath the colour that matters more than the shade does: whether you buy the door already painted, or buy it primed and paint it yourself. That choice sets what the finish looks like, what it costs you in weekends, and what happens the first time somebody puts a suitcase through it.

Factory-painted, or primed and painted grey?

A factory-painted door is sprayed flat under controlled conditions and cured before it is wrapped. A primed door is an undercoat and an invitation. The difference in the finished surface is real and visible, and so is the difference in what you can do about it later.

Grey is not one colour

Every grey has an undertone, and the undertone decides whether the door looks right in the room. A blue-grey next to a warm oak floor reads cold and slightly grubby. A warm greige next to cool white walls reads beige rather than grey, and people describe it as dirty without being able to say why.

The three families worth telling apart are the cool blue-greys, the warm greiges that carry a little brown, and the near-neutrals that sit between them. Anthracite and charcoal are a separate decision again — they behave like a dark colour rather than a neutral, and they make a small room read smaller.

  • Judge the colour against your floor and your walls, never against white paper.
  • Look at it in the actual room, in daylight and under the lights you use at night.
  • North-facing rooms pull a grey colder; south-facing light warms it.
  • If the trim is staying white, hold the grey against that white specifically — a brilliant white and a soft white sit very differently against the same door.

Trimming and repairing a painted door

This is the part that catches people out, and it is the honest cost of buying a door that arrives finished. The paint is on the outside. Cut into it and you expose the substrate underneath, which on a painted MDF door is a pale, absorbent edge that looks nothing like the face.

So trimming has to be followed by sealing and painting the cut edge, and a brush will not match a sprayed finish exactly — close enough for an edge nobody sees is the realistic target. How much you are allowed to take off at all is set by the manufacturer rather than by us, and it varies by model, particularly on a door with a lock block. Check what came with the door before the saw comes out.

The same applies to damage. A chip in a factory-painted face cannot be repaired invisibly in place, because you are matching a sprayed finish with a brushed one. On a door that gets knocked — a kitchen, a utility, anywhere a pushchair lives — that is a genuine argument for buying primed and painting it yourself, so that you own the tin and can go over the whole face when it needs it.
