How to Paint a Space Marine Squad Like a Battle-Hardened Commander

You’ve seen those box-art Space Marines—pristine, shiny, like they just walked off the assembly line. But that’s not how they look after a week in the trenches of Armageddon. A true commander knows his squad earns its scars. So let’s ditch the parade-ground gloss and paint a squad that looks like it’s been through hell and back. Welcome back to The Grimdark Brush, where we treat miniatures like war, not wallpaper.

I’ll walk you through the whole process step by step. No airbrush required, no expensive pigments. Just brush control, patience, and a little dirty thinking.

The Gear Check – What You’ll Need

Before we start slapping paint, get your kit sorted. I keep mine in an old ammo box—keeps the grit in the right place.

• Primer: Chaos Black spray (or any matte black). No grey primer here—battle-hardened means deep shadows.
• Base paints: Your chapter’s main color (e.g., Macragge Blue for Ultramarines), a metal like Leadbelcher, and a brown/earth tone for weathering.
• Shades: Agrax Earthshade and Nuln Oil. You’ll use more Agrax than you think.
• Drybrush: An old, flat brush with stiff bristles.
• Sponge: A piece of foam from a blister pack or an old dish sponge. Crumble it up.
• Texture paint: Stirland Mud or Armageddon Dust. Or just cheap sand + PVA glue + brown paint.
• Decals: Only if you want to. I often skip them for that battle-worn feel.

And yes, your hands—the most important tool. No pressure—just breathe and commit. For more on painting monstrous creatures, see our guide on painting a Chaos Space Marine Daemon Prince.

Step 1: Prime Like You Mean It

Shake the can for a full minute. Then another 30 seconds. Prime your marines in short bursts from about 20 cm away. Rotate each mini so every recess gets covered. Lay them on a strip of masking tape on a stick—I call it the “lance”. This keeps your fingers off the model.

Let them dry at least an hour. Rushing primer is like rushing a patrol—you get ambushed.

Step 2: Basecoats – The First Line of Battle

Now we start building that worn-in look. Thin your paint, but not too thin. You want coverage, not soup.

For the armor plates: Apply two thin coats of your main color. Don’t worry about perfect coverage—some black peeking through in shadows is a feature, not a bug. Focus on the raised areas. Let the raised areas. Let the recesses stay dark.

**For the joints and under-suit the recesses stay dark.

For the joints and under-suit: Abaddon Black (it’s already black from primer, so just touch up any spots where you spilled blue). Use a small brush to carefully paint the ribbed sections.

For the weapons: Leadbelcher on the bolter casing, the barrel, and the backpack exhausts. Keep it thin.

For the helmet lenses: Mephiston Red (or Caliban Green for a different chapter). Don’t worry about the lens glow yet.

Step 3: Agrax Earthshade – Your Best Friend in the Trenches

Here’s where The Grimdark Brush philosophy kicks in. Shade your entire marine—no, really. Wash the whole model with Agrax Earthshade, not just the recesses. Load your brush and let it flow into every crevice. Don’t let it pool too thick on flat surfaces, but a little staining is fine. That dirty brown tinge is what makes them look like they’ve been crawling through mud.

Wait 10 minutes. Remove any heavy pools with a clean damp brush. Then let it dry completely. This step transforms a clean model into a gritty survivor.

Step 4: Drybrush – The Harsh Sun Reveals the Scars

Once the wash is bone dry, grab your drybrush. Dip it lightly into the same base color (Macragge Blue, for example). Wipe most of it off on a paper towel until almost no paint comes off. Then brush the edges of the armor plates, the knee pads, the shoulder rims. This catches the highlights. You want a rough, stippled effect—not smooth edge highlighting. That’s for parade-ground painters. We’re fighting for real.

For extra definition, do a second drybrush with a lighter tone (e.g., Calgar Blue) on only the very sharpest edges—like the top of the helmet, the knuckles, and the pauldron trim.

Step 5: The Sponge – Battle Damage in 30 Seconds

This is my favorite part. Tear off a small piece of sponge (like from an army transport foam). Dip it into some Leadbelcher or Dark Reaper (a dark grey-blue). Dab most of it off on a paper towel. Then stipple the edges of the shoulder pads, the tips of the kneecaps, the edges of the backpack. This simulates chipped paint from shrapnel and impact.

Don’t go crazy. Three or four dabs per marine is plenty. You can always add more later. Less is more—until you see how cool it looks, then you might overdo it. I’ve ruined a squad that way. Trust me.

Step 6: Faces and Lens Glow (Keep It Simple)

Helmetless marines? Paint the face with Bugman’s Glow, wash with Reikland Fleshshade, then highlight the nose, cheeks, and brow with Cadian Fleshtone. Don’t bother with eyes unless you have a magnifying lamp and steady hands. A recess of black and a tiny dot of white works. Or just skip eyes—they’re wearing helmets anyway, right?

Lenses: Paint the whole lens with Mephiston Red. Add a sliver of white in the upper left corner. Done. You want a glow, not a painting tutorial.

Step 7: Basing – Tell Their Story

The base is the final piece of the narrative. A battle-hardened squad doesn’t stand on a pristine urban base. They stand on mud, rubble, or ash.

My go-to: Stirland Mud texture paint. Apply it thick, but leave a few areas bare for contrast. While it’s wet, press a small piece of cork (like from a wine bottle) or a tiny rock into the mud. Let it dry overnight. Then drybrush the whole base with a pale brown like Zandri Dust. Adds dust to the marines’ boots too.

Optional: Add a tuft of dead grass (Gamers Grass “Burnt Grass”). Not too many—just one per base. It’s a battlefield, not a meadow.

Step 8: Final Verdict – The Squad Leader’s Inspection

Lay your five marines on the table. Step back. Look at them under a strong light. Are there any shiny spots? Knock them down with a thin wash or a dab of matte varnish. Any mold lines you missed? Too late now—just call it battle damage.

Decals? If you want, add a chapter badge on the left pauldron. Use Micro Sol and Micro Set to make it snug. Then hit it with a sponge dab of your base color to blend it in. Gives the decal a worn, painted-over look.

And that’s it. You’ve got a squad that looks like they’ve seen action, not a display case—for a full walkthrough, see our guide on How to Paint a Space Marine Squad Like a Battle‑Hardened Commander. Every time you field them, remember—they’re veterans. They earned their dents. And when you play, and your opponent asks, “How’d you get that weathered look?” you can just wink and say, “Years of practice… and a little Agrax.”

Keep your paints thin, your brush clean, and your head low.

The Grimdark Brush is always here when you need a break from the clean-and-shiny meta. Go paint some war.
