You ordered it in October. It's late November. You have a date in December and you're starting to make small worried noises at the studio.

Here's what's actually happening in that room, and why the answer isn't “work faster.”

Oil paint doesn't dry. It cures. It reacts with oxygen over months, and the reaction continues long after the surface feels hard. Most of a commission's lead time isn't painting — it's waiting for chemistry, and there is no way to pay to make chemistry hurry.

The Received Wisdom: Painting Time Is Labour Time

Everyone assumes lead time is a queue of hours. Twenty hours of painting, therefore about three days, therefore why is this taking six weeks?

Because oil is a layered medium, and each layer has to be touch-dry before the next one goes on. A painting needing four layers needs three waits.

The brush is in contact with the canvas for a small fraction of the elapsed time. The rest is a canvas standing against a wall doing something invisible.

Decode The Actual Timeline

StageElapsedWhat's happening
Photograph review and approval1–3 daysThe studio checks resolution, lighting and whether the shadow side of every face exists. This is where problems are cheap to fix.
Underdrawing and toned ground1–2 daysComposition locked. Changing your mind after this gets expensive.
Underpainting2–4 days, plus dryingThe tonal structure. Everything above depends on it being right.
Main paint layers2–4 weeksPainting sessions separated by drying intervals. The waits are longer than the sessions.
Detail and final passes3–7 daysFaces, hands, highlights. The part everyone thinks is the whole job.
Proof photograph and revisions2–5 daysYou see it. You get one round of changes at most studios.
Surface-dry before packing1–2 weeksNon-negotiable. A canvas packed too early arrives with the packing material printed into it.

The Key: Curing Is Not Drying, And The Difference Is Everything

Watercolour dries. Acrylic dries. Water leaves, the film is finished.

Oil does something else entirely. The oil binder reacts with oxygen and cross-links into a solid film, and that reaction runs for months and then keeps running, slowly, for years.

Consequences, all of them practical:

  • Touch-dry is not cured. A surface can feel hard while the layers beneath are still reacting.
  • Thick paint cures far slower than thin. Impasto can stay soft underneath for a very long time.
  • Certain pigments are much slower than others. Some earths and blacks are notoriously sluggish; a painting isn't uniform.
  • Varnish too early and you seal a living film. Traditional practice says six to twelve months. Modern synthetic varnishes can go on far sooner, but they're a different product with different removability, and the studio should tell you which.
  • Never frame an oil under glass. A sealed cavity around a curing surface is a small humid box, and eventually you get a milky bloom.

So What Does A Rush Fee Actually Buy?

Queue position. That's it, and it's worth saying plainly because it's worth money and it's routinely oversold.

A rush fee moves your commission to the front of the studio's schedule. If they have six pieces in progress and you need yours by a date, that is a genuine service and paying for it is rational.

What it cannot do is accelerate curing.

So the honest shape of a rush is: the painting stage compresses, the drying stage doesn't, and what you save is the waiting-to-start time rather than the waiting-to-dry time.

Any studio promising a large oil painting fully cured and varnished in a fortnight is describing something that is not oil paint. Ask what medium they're actually using. The answer is usually acrylic, or oil with a heavy alkyd drier, and neither is dishonest — but you should know before you pay for “oil.”

The Christmas Question, Answered Properly

You want it byOrder byRealistic size
Mid-DecemberLate SeptemberAny size, comfortably
Mid-DecemberLate OctoberUp to about 60 × 80 cm, with a rush fee
Mid-DecemberNovemberSmall only, and expect it to arrive uncured — handle carefully, varnish next year
Mid-DecemberDecemberBuy a print, commission the oil in January, and give a photograph of the proof in a card. This is a genuinely good move and studios will help you do it.

Living With A New Oil Painting

  • Hang it, don't stack it. Air on both sides.
  • Not above a radiator, not in direct sun. Heat and light are the two things that damage a curing film fastest.
  • Don't clean it. At all. For a year. No cloth, no water, no spray, and absolutely no household cleaner — ever, actually, not just in year one.
  • Wait to varnish. Six to twelve months for a traditional varnish. Ask the studio what they recommend for the specific paints they used.
  • If you must move it early, carry it by the stretcher edges, face outward, and never let anything touch the surface.

Three Questions Worth Asking

How long does a commissioned oil painting take?

Typically four to eight weeks from approved photograph to dispatch for a studio commission, longer for large or complex pieces. Most of that is waiting rather than painting. An independent named artist working alone commonly quotes months.

When can it be varnished?

Traditional practice says six to twelve months, because oil cures by reacting with oxygen rather than drying by evaporation, and the reaction continues long after the surface feels hard. Modern synthetic varnishes can go on sooner but are a different product — ask which one the studio used.

Is a rush fee worth paying?

Sometimes, and it buys queue position rather than speed. That's real and worth money if you have a date. It cannot accelerate curing, because that's chemistry rather than labour.

The Verdict

Your painting isn't late. It's still reacting with the air in the room it was made in, and it will still be doing that, slowly, when you've forgotten you ordered it.

That is not a defect of the medium. It's the reason oil paintings from the fifteenth century are still here to be copied, and posters from 2019 have already gone orange.

Order earlier. Then leave it alone.
