If you want to paint a whole army quickly without pouring hours into every model, slapchop is for you. Short answer: Slapchop means priming a model black, then drybrushing grey and white to build a black-and-white "light map," and finally laying a single coat of transparent Contrast/Speedpaint over the top. The colour inherits the value underneath, so it reads dark in the recesses and bright on the raised edges. That is what makes it the fastest route to tabletop-quality armies.
The name comes from the quick "slap and chop" drybrush motion. The trick is this: you finish all the hard value work in the greyscale (black-and-white tone) stage, so colouring takes only minutes. And even in a beginner's hands, it produces a dramatic jump in quality.
What is slapchop and what is it for?
At its core, slapchop is a speed-painting technique that applies zenithal (top-down light) logic by brush, in its fastest possible form. The idea is simple: the greyscale base underneath sets how bright the transparent colour on top will read.
To get there, you build three values. The black base is your deepest shadow; the grey drybrush (dry-brush) is your mid-tone; and the white drybrush touches only the highest raised areas as your light. Lay a transparent Contrast-type colour over that black-and-white map and the colour reads bright on white edges, dark in black recesses. The result is an instantly volumetric, shaded-and-lit model from a single coat.
So where did the technique come from? According to the Minipainting Wiki, slapchop was first introduced by The Honest Wargamer's founder Rob Symes in a YouTube video; Goonhammer notes him as a former Warhammer TV team member. It spread around 2022 and radically sped up army painting, because it shifted the hard value work onto a cheap, fast drybrush stage.
When do you use it? Above all, whenever you need to paint lots of models, an army, fast and consistently. Philosophically it walks the same road as One-Coat Techniques: maximum result from minimum brushwork.
How does slapchop work?
There is really just one idea to grasp here: the value matters, not the colour. A transparent paint does not cover the surface; it filters down and shows the lightness or darkness beneath it exactly as it is.
This is precisely why the heart of slapchop is not the colour but the greyscale base before it. Done with an airbrush, the same principle becomes Zenithal Priming; slapchop is its brush-only cousin that needs no spray gear and leans entirely on the drybrush.
The secret of slapchop is not in the colour, it is in the greyscale underneath. Build that base carelessly and the result reads flat no matter what colour you lay on top.
On the colour side, Contrast & Speedpaint Systems do the heavy lifting. These paints both deliver colour and pool in the recesses to leave shade in a single coat, which makes them a perfect match for slapchop.
How do you do it step by step?
Slapchop is really four core steps, with an optional fifth finishing touch. On a single model, run the order like this:
- Black prime: Prime the model with black primer. Your entire shadow map starts from this black.
- Grey drybrush: Drybrush the whole model with a light grey acrylic. This sets the mid-tone; wipe the brush off on a paper towel until it is almost dry.
- White drybrush: Very lightly catch only the topmost raised areas with white or off-white. These are the spots that catch light, so do not overdo it.
- Transparent colour: Lay a single coat of Contrast/Speedpaint/Xpress on each area. As the paint flows, let the value underneath supply shade and light on its own.
- (Optional) Detail/accent: Add a few edge highlights (sharp catches on edges), eyes and metallic details; the model jumps to "tabletop+" in seconds.
Notice that all the real work finishes in steps 1-3. Step 4 is just "dressing" the colour on, and it genuinely takes minutes. One practical note: keep the grey drybrush generous and covering so the black stays only in the deepest recesses, but use the white sparingly so it catches only the high points. The balance between those two tiers is what decides how three-dimensional the model looks.
Which paints and brushes do you need?
Here is the good news: slapchop does not demand a huge shopping list. The core kit is simply this:
- Black primer: Spray or airbrush; a smooth, thin black base.
- Grey and white acrylic: Two separate bottles for mid-tone and light are enough.
- A good drybrush brush: A flat, stiff-bristled brush gives the cleanest drybrush. This is the real tool of the value map, so invest in a good one.
- Contrast / Speedpaint / Xpress paints: The colour layer of slapchop. Bright, saturated tones give the best result.
- Paper towel: Mandatory for unloading the brush before each drybrush pass.
One simple rule helps when choosing colour: light, vivid tones shine in slapchop. Very dark colours swallow the value difference underneath, so avoid them or use them as targeted shade only.
An optional but genuinely useful addition is a wet palette. Getting the grey and white to the right consistency and keeping them moist before drybrushing helps you stay consistent between tiers. In batch painting, that is the easiest way to get the same result from model to model.
The most common mistakes
Slapchop is a forgiving technique, but four classic mistakes will easily flatten the result. Steer clear of these:
- Drybrushing white too widely: When light spreads everywhere the contrast disappears and the model reads white and flat. White should stay on the very top edges only.
- Leaving too much paint on the brush: Excess paint in a drybrush makes a chalky, blotchy base. The brush should be almost completely dry.
- Using an opaque paint: Laying colour with a non-transparent or thick paint smothers all the value beneath, so shade and light vanish.
- Building the base carelessly: Slapchop's quality depends entirely on the greyscale. Rush the drybrush stages and no colour can rescue it.
Professional tips
A few small tweaks move a slapchop result from "fast but cheap" to "fast and sharp":
- Use a warm greyscale: This is Stahly's hack from Tale of Painters; instead of pure black to pure white, run a warm dark grey to a light ivory. The result reads more natural and warm, never plastic-cold.
- Nail the drybrush ladder: With three clean values (black, grey, white) and clear transitions between them, the colour sits cleanly too. The secret is this ladder, not the colour itself.
- Pick saturated colours: Light, vivid tones show the value best; very dark colours hide the difference.
- Add a finishing touch: A few edge highlights, a glossed eye and a spot of metallic lift the model above the tabletop average.
Frequently Asked Questions
Do I absolutely need Contrast paint for slapchop?
No; what drives the logic is the transparent paint, not the brand. Citadel Contrast, Army Painter Speedpaint and Vallejo Xpress Color all do the same job: one coat that gives colour and leaves shade in the recesses. So start with whatever transparent system you own; fine-tune later.
Is slapchop suitable for beginners?
Yes, and it is arguably at its strongest right there. Because the drybrush handles the hard value work, the colour layer is nearly foolproof. New painters usually see a dramatic quality jump on their first slapchop model, which is exactly why it is the most encouraging way to start painting an army.
Can I skip the grey and white drybrush?
No; those two rungs are the very heart of the method. Lay Contrast over a plain black base and the model comes out dark and flat, with no volume at all. The whole three-dimensional feel of slapchop comes from the grey mid-tone and the white light. Do not rush them, and never skip them.
Why don't dark colours look good with slapchop?
Because a dark transparent colour swallows the light-dark difference underneath, so even a white edge barely brightens. Light, saturated tones, by contrast, reveal the value clearly. If a dark colour is essential, use it as targeted shade in the recesses rather than over a large surface, or deepen it later with a glaze.
How long does slapchop take per model?
Once the primer and drybrush are dry, the colouring genuinely takes minutes; the real time sits in the drybrush ladder. Across a whole army that gap multiplies: build the same three-value base in series, then run colour over them fast. For speed, pair it with Batch Painting.
How do I take a slapchop model to "tabletop+"?
By adding a little handwork on top of the basic slapchop. A few crisp edge highlights, one neatly painted eye and a handful of metallic details are enough. These touches take minutes but separate the model from the batch-painted average and give it a display-case feel.
The takeaway
There is one golden rule to remember: the base is everything. Build the black-grey-white value map cleanly and a single coat of transparent colour does the rest, giving you a shaded, lit model in minutes.
