Your first month of oil painting

Oil painting looks slow and intimidating from the outside. It isn't — but you do need to understand the material before it stops fighting you. Here's what your first four weeks actually look like, without the mythology.

Oil painting has a reputation for being the most serious, most demanding, most adult art medium. Five centuries of master painters will do that. But the reputation is mostly theater. The actual experience of starting oil painting is quieter: a lot of looking, a lot of mixing, a lot of watching paint behave differently than you expected — and then, gradually, learning to predict it.

What makes oil painting genuinely different from acrylics or watercolor isn’t difficulty — it’s time. Oil paint dries in days, not minutes. That single fact changes everything about how you work, what mistakes are fixable, and what you learn to love about the medium.

Week 1: Understanding what you’re working with

Before you make a painting, spend a session learning how the paint behaves. This sounds boring. It is the most valuable hour you’ll spend all month.

Set up your space. Oil painting requires some ventilation — even Gamsol, the safest solvent, should be used near an open window. Get a glass jar for your solvent (don’t use plastic — Gamsol will dissolve the lining over time). Have paper towels within arm’s reach.

Do a paint-out. Squeeze small amounts of every color in your set onto your palette. Mix each one with a small amount of Gamsol to get a thin, fluid consistency. Brush each color onto a canvas board in a fat stripe. Wait two days. Come back and see what changed: some colors shift slightly, some stay identical, all of them lose the wet sheen. This is what you’re working with.

Try the fat-over-lean rule immediately. For your first layer (the underpainting), thin your paint with a lot of Gamsol — the consistency of cream. For the next layer, use slightly less solvent and maybe a drop of linseed oil. For the final layer, use paint straight from the tube or with just a touch of linseed. You’re making each layer fatter (oilier) than the last. This is not optional if you want paintings that don’t crack in ten years.

What to actually paint in week one: A monochromatic study. One color, plus white and black. Paint a simple object — an egg, a lemon, a crumpled piece of cloth — using only that single hue. The constraint forces you to focus on value (light vs. dark, not color) and it teaches you how oil paint moves without color-mixing confusion getting in the way.

Week 2: Your first real painting

In week two, you make a painting — not a study, a painting. Something with color, a subject you chose, a composition you arranged.

Keep the subject simple. A piece of fruit. A coffee mug. A single flower in a glass. Still lifes have been beginner subjects for five hundred years because they’re good beginner subjects: they don’t move, they have volume, and they force you to actually look hard. A red apple on a white cloth teaches you more about painting than any abstract exploration you’re ready for in month one.

Start with a toned ground. Before painting anything, brush a thin coat of burnt umber or raw umber, thinned with Gamsol, over the whole canvas. Let it set for an hour (oil paint doesn’t dry to the touch overnight, but thin washes get tacky enough to paint over in an hour or two). Then wipe away the lightest areas with a rag, establishing your composition in this single brown value before you touch a color tube.

This is called the “toned ground and wipeout” method, and it’s the fastest way to get a structured painting going as a beginner. You’re not building from white — you’re building from a mid-tone down into darks and up into lights simultaneously.

On color mixing: Start with a limited palette. Four to six colors is all you need: a warm and cool version of each primary — cadmium yellow and yellow ochre, cadmium red and burnt sienna, ultramarine blue and cerulean — plus titanium white. You can mix almost anything from this selection, and it forces you to learn how colors actually combine rather than reaching for a tube that’s close enough.

Week 3: Layers and patience

The third week is where oil painting either hooks you or loses you. The drying time, which felt like a problem in weeks one and two, starts revealing itself as the feature it actually is.

Wet-on-wet vs. wet-on-dry. Oil paint is workable for hours after you put it down. If you’re painting wet paint over a wet surface, the colors blend into each other — useful for soft transitions, landscapes, smooth gradients. If you let a layer dry fully (usually 24-72 hours depending on paint thickness and humidity) before painting over it, you can put hard, clean strokes on top without disturbing what’s underneath. Both approaches are valid. The trick is choosing deliberately rather than just running out of patience.

Glazing. Once a layer is dry, you can apply a thin, oil-rich, transparent layer over it — a glaze. Glazing is how traditional oil painters built up the depth and luminosity in those rich old-master shadows. It’s also how you deepen a color without obliterating what’s already there. Try it on a finished painting: mix a transparent color (burnt sienna, ultramarine, or viridian work well) with Liquin until it’s very fluid, and brush it thinly over a dry area. See what it does.

The problem most beginners hit in week three: Overworking. You have a good passage — a background, a shadow, an area that finally looks right — and you keep touching it. Stop. Oil paint forgives almost everything, but it doesn’t forgive being scraped and re-scraped six times in one session. When something looks good, put down the brush and paint something else.

Week 4: Building a practice

By week four, the material stops feeling foreign. You know roughly how long things take to dry. You know which brushes you reach for. You have a sense of your palette.

Start every session with a few warm-up strokes. Load a big brush with your most-used color, make five strokes on a scrap board, and look at them. Are you tense? Is the paint too thick? Are you fighting the brush? Warm-up strokes cost nothing and tell you immediately what’s happening with your control that day.

Value before color, always. If you squint at your painting until you can barely see it, what you see in that blurry near-darkness is the value structure — the map of light and dark areas. That map should be legible independent of color. If it reads as a muddy flat field of similar grays, your values are too similar and the painting will feel flat no matter how nice the colors are. Take out your phone, photograph the painting, convert the photo to grayscale, and look. That grayscale image doesn’t lie.

What you’ve actually learned by month’s end: How to thin paint for underpaintings. How to apply fat layers on top of lean ones. How to build a still life from a toned ground. How to not wreck a good passage by overworking it. How to use Gamsol safely. How your palette’s colors interact.

That’s more material foundation than most self-taught painters build in six months, because oil painting forces you to learn the rules — the drying, the chemistry — in a way acrylics don’t require.

Things you’ll fail at — and that’s normal

Impatient overpainting. You paint over a layer that wasn’t ready, the colors mud up, and everything goes brown. Wait longer. If you can’t wait, use Liquin to speed the underlying layer.
Too much solvent. Gamsol-heavy paint gets thin and runny and has trouble staying where you put it. You don’t need much — a little goes a long way.
Painting too small. An 8×10 canvas board feels tiny but isn’t. A 5×7 is genuinely too small for most beginner technique. Work at 8×10 minimum.
Skipping the toned ground and panicking at the white canvas. Just tone it. A thin wash of burnt umber takes three minutes and makes everything easier.
Giving up on a painting too early. Oil paintings go through ugly phases — especially around the second session, when you’ve covered the clean underpainting but haven’t refined anything. This is normal. Keep going.

What to do in month two

Copy a painting you love. Find a painting — a Sargent portrait, a Hopper interior, anything — and reproduce it. Copying forces you to read decisions you’d never examine in your own work: where is that edge? Is that color actually that warm? This is how European painters trained for centuries and it still works.
Work from life, not photos. Photos flatten value relationships and destroy color temperature information. Painting from life — even a simple still life you set up on your kitchen table — teaches you to see in a way that working from photos doesn’t.
Take a class around month two or three. Not before. After a month of painting, you have enough context to know what to ask — and a single session with a competent teacher who can look at your actual work will identify the two things holding you back faster than six months of YouTube.
