Short answer: Overbrushing is a wetter, paint-heavier version of drybrushing (dry brush). You deliberately leave more paint on the brush, so instead of catching only the sharpest raised edges you lay down a flatter, smoother mid-tone highlight across a wider area. By mid-tone highlight we mean the broad lit zone that sits one step below the very brightest edge accents. That makes it exactly what you want on armour plates, vehicle hulls and broad cloaks when you need fast volume.
To place it on the map, think of it as sitting between drybrush and layering (building a colour up in thin, controlled coats). It keeps the speed of a drybrush but reads as less dusty and more integrated. In other words, it is not for fine edge highlights; it is for laying down a broad mid-light base.
What is overbrushing and what is it for?
At its heart it is a simple move: you only partially wipe a stiff, broad brush, then sweep it across the wide surfaces of a model. The real distinction lives in the paint load, because with a drybrush you remove nearly all the paint, whereas with an overbrush you leave noticeably more on the bristles.
That small difference shows up directly in the result. A drybrush deposits tiny specks of pigment on the highest points and gives a grainy, spotty texture. An overbrush, by contrast, covers a larger area and leaves a flatter, broader band of light.
So where does it earn its place:
- Laying a quick mid-light coat on large surfaces such as armour plates, vehicle hulls and big cloaks.
- Lifting overall brightness a notch after a zenithal prime or a slapchop (a fast black-and-white base).
- Getting a more integrated transition wherever a drybrush looks too spotty or dusty.
How is it different from drybrushing?
Both techniques share the same motion, and the only thing that changes is the amount of paint on the brush, yet that single variable decides everything. Picture a slider: at one end the nearly dry drybrush, at the other the full control of layering, with overbrush sitting somewhere in the middle.
The easiest way to explain it is with The Army Painter's framework. In their terms, a heavy drybrush is the first broad highlight, a light drybrush is the soft final transition, and an overbrush gives flatter, broader coverage with a slightly wetter brush.
Miniwargaming's Jay, in the "Miniature Painting 101" series, draws the line clearly: overbrush and drybrush are the same sweeping motion, and the only variable is how much paint you leave on the brush.
In practice, use it like this: if a drybrush looks too dusty, leave a bit more paint on the brush and slide toward overbrush. If the detail is getting buried instead, take paint off and move the other way, back toward drybrush.
How do you do it step by step?
Here is the good news: overbrushing needs no special kit beyond a stiff brush and a paper towel. The motion is broad and quick, and you get your control from the paint load, not from the brush tip. The steps go like this:
- Pick a stiff, broad brush. The one you already use for drybrushing is perfect.
- Load the paint, then partially wipe the excess on a paper towel. The key is restraint: not as much as a drybrush, since visible paint should remain on the bristles.
- Make broad sweeping passes across the wide surfaces of the model, at an angle steeper than 45 degrees and with light pressure.
- The first pass covers the broad area, and this becomes your mid-light base.
- If you want, hit only the sharpest points with a second, drier pass (a true drybrush) on top.
It is as fast as a drybrush and well within reach for anyone from beginner to intermediate.
The direction of the stroke matters just as much as the paint load. Because light comes from above, sweep the brush down from the model's upper faces toward the shadows, following the direction the light falls. Aim for a few flowing passes rather than single hard strokes, so the marks blend into each other and the layer reads far more integrated.
Which paints and brushes?
The first thing to keep in mind is that overbrushing does not need expensive bristles; in fact, wearing down a fine, pointed kolinsky (sable-hair) brush on it is simply a waste. What you actually want is far more modest:
- A stiff, full-bodied drybrush. Dedicated drybrush ranges from Citadel, Army Painter or Artis Opus are ideal, and an old round brush with a blunted tip works perfectly well too.
- Standard acrylic paint. Normal-consistency paints from Citadel or Vallejo are plenty. Slightly thinned paint spreads flatter, but thin it too far and you lose the drybrush-style control.
- Paper towel. For partially unloading the brush and running test strokes.
This is where test strokes become essential: scribble a couple of marks on the towel and read the flow before you touch the model. If the brush leaves a flat trail you are ready; if it leaves a wet blob, wipe off a little more.
The most common mistakes
Overbrushing is easy to pick up, but it goes wrong just as easily when you rush. Three culprits come up the most:
- Not unloading enough paint. Too much paint left on the brush gives you thick blotches and obvious brush marks. Worse, a pass cannot be undone, so you usually have to strip back and start again.
- Overbrushing very fine surfaces. Chainmail, slim facial features and small details get smothered by this technique. Use a drybrush or layering there instead.
- Hitting the whole surface without thinking about light direction. Light comes from above, so focus on the upper faces and leave the lower parts in shadow. Otherwise the model reads flat and volumeless.
Pro tips
Once the motion feels comfortable, a few habits let you chase speed and volume at the same time. Here are the ones worth building in:
- Chain overbrush and drybrush. Lay the broad mid-light base with an overbrush first, then catch only the sharpest points with a drybrush. Together they give a fast but volumetric highlight.
- Tune the paint load on the towel. Run a test stroke after every reload, because the flow changes as the brush dries out.
- Soften afterward. If the overbrush transitions look too sharp, pull a thin glaze (transparent transition) or wash (shading) over them to blend.
- Pair it with zenithal. A single overbrush layer over a zenithal prime gives an otherwise half-finished model instant volume.
- Go one shade lighter on colour. Because overbrush spreads over a wide area, pick a colour only a shade or two lighter than the base; jump too far and the transition turns harsh, stay too close and the effect barely shows.
Frequently Asked Questions
What is the difference between overbrushing and drybrushing?
The only difference is how much paint you leave on the brush. With a drybrush you wipe off nearly all of it and deposit tiny specks on the sharpest edges. With an overbrush you leave noticeably more, which produces a broader, flatter band of mid-tone light across the surface.
When should I use overbrushing?
Use it to lay a fast mid-light base on large, flat surfaces such as armour plates, vehicle hulls and broad cloaks. It is also ideal for lifting overall brightness after a zenithal prime or a slapchop. When you reach fine detail, switch to a drybrush or to layering instead.
Which brush should I use?
A stiff, full-bodied drybrush is best. Dedicated drybrush ranges from Citadel, Army Painter or Artis Opus fit perfectly. Wearing a fine, pointed kolinsky down on this job is both unnecessary and hard on the bristles. Even an old, blunted round brush will do the work.
Should I thin the paint for overbrushing?
Thinning slightly helps the paint spread flatter and reduces brush marks. But the moment you thin it too far you lose the drybrush-style control and start leaving wet blobs. The safest route is to start with normal-consistency paint and tune the flow with test strokes on a paper towel.
Is overbrushing suitable for beginners?
Yes, very much so. If you have tried drybrushing, overbrush is just one step beyond and uses the same motion. It is a quick technique that anyone from beginner to intermediate can manage. The real skill is finding the right paint load on the brush, and that settles in after a few attempts.
What if my overbrush marks come out too harsh?
If the transitions look hard, pull a thin glaze or wash over them to soften. Next time, leave less paint on the brush and use lighter pressure. Rather than fighting a bad layer, it is usually cleaner to pass back over it with a thin mid-tone and rebuild.
Key takeaway and next step
To hold overbrushing in one line: it is the speed of a drybrush plus a half-step toward layering. It builds volume on broad surfaces in minutes, and if you then chain it with a drybrush, you get a highlight that is both fast and full of volume.
To really lock the technique in, it helps to learn its neighbours too: for the basics, Drybrushing and Layering; to soften transitions, Glazing and Washing, Shading & Pin Wash; for a solid base, Zenithal Priming and Edge Highlighting.
