Common Mistakes When Painting D&D Miniatures (And How to Avoid Them)

Quick answer

Most common miniature painting mistakes come from skipping surface prep, thinning paint too little, or applying washes too heavily. Fix the cause, not just the symptom: clean mold lines, prime or check factory primer, thin acrylics to a skim-milk consistency, and wick away excess wash before it pools. If a figure is already sealed or heavily textured, stop before you damage detail and consider a repaint or a fresh model instead.

Painting D&D miniatures should be relaxing, but a few repeatable mistakes turn a fun session into a frustrating rescue job. The good news is that almost every common problem has a visible symptom, a likely cause, and a straightforward correction. This guide separates those three so you can diagnose what went wrong and decide whether to fix it or move on.

The advice below applies to any acrylic-painted figure, including pre-primed lines like D&D Nolzur's Marvelous Miniatures. You will learn what to check before you paint, how to correct the most frequent issues, and the point where pushing further will cost more detail than it saves.

Mistake 1: Skipping prep and painting over mold lines

Symptom: paint collects along a raised seam, or a thin ridge shows through your base coat no matter how many layers you add. Cause: leftover mold lines or flash from the casting process. Corrective action: scrape the line with a hobby knife back edge or fine file, then smooth with a soft brush before priming. If the figure is already painted, you can sometimes hide a minor line with a dark wash, but a thick ridge will always telegraph through.

Nolzur's Marvelous Miniatures arrive primed and ready to paint, but that does not mean they are free of mold lines. Check the joins on arms, wings, and tails before you commit to a color scheme. A few minutes with a blade now prevents a muddy, lumpy finish later. If the line sits in a deep recess or across a fragile part, weigh whether the fix is worth the risk of bending or snapping the piece.

• Run a fingernail along seams to feel for ridges before painting.
• Scrape away from detail, not toward it, to avoid gouges.
• Re-prime only the scraped area if bare plastic shows.

Mistake 2: Painting with unthinned or over-thinned paint

Symptom: brush strokes stay visible, detail clogs, or the paint runs into recesses and dries unevenly. Cause: paint straight from the pot is usually too thick, while paint thinned with too much water loses coverage and breaks apart. Corrective action: thin acrylics on a palette with a little water or medium until they flow like skim milk, then apply two thin coats instead of one thick one. If the paint already dried thick, strip the figure with isopropyl alcohol and start again.

Thinning is the single biggest lever on miniature painting problems. A thin coat lets the sculpt's detail show, and a second coat builds opacity without texture. If you are painting Nolzur's figures, the factory primer accepts thinned acrylics well, but you still need to control your consistency. When a layer looks streaky, let it dry completely before judging it, because acrylics darken slightly as they cure.

• Test consistency on your thumbnail: it should cover without beading.
• Use a wet palette to keep thin paint workable longer.
• Never go back over wet paint with a loaded brush; wait for it to dry.

Mistake 3: Flooding the model with wash

Symptom: the figure looks dirty, glossy, or stained instead of shaded, and flat areas have dark tide marks. Cause: too much wash applied at once, or a wash that is too dark for the base color. Corrective action: apply wash with a moderately loaded brush, then immediately wick away pools from flat surfaces with a clean dry brush. You can also thin the wash with medium or water before applying it, which gives you more control.

Washes are supposed to settle in recesses, not coat the whole model. If your figure already looks muddy, you can often rescue it by re-layering the original base color on the raised areas, leaving the wash only in the crevices. On large flat surfaces like cloaks or dragon wings, consider a targeted pin wash instead of an all-over wash. Stop if the wash has dried glossy and tacky; another layer will only make it worse.

• Wick excess wash from flat areas before it dries.
• Match wash color to the base: brown for warm tones, black for cool.
• Use a matte varnish later to knock down any remaining shine.

Mistake 4: Rushing highlights and drybrushing

Symptom: chalky, scratchy edges or a dusty haze over the whole figure. Cause: too much paint left on the drybrush, or drybrushing over a surface that is still tacky. Corrective action: wipe the brush on a paper towel until almost no paint comes off, then brush lightly across the raised detail. If you already created a chalky layer, you can sometimes smooth it with a thin glaze of your mid-tone, but heavy drybrush texture is hard to reverse.

Drybrushing is fast, but it is also one of the most common miniature painting mistakes because it is easy to overload the brush. For character models, edge highlighting with a fine brush gives more control. For monsters and terrain, drybrushing is efficient as long as you build it up slowly. If the figure is small and detailed, stop drybrushing and switch to layering before you lose the face or scales.

• Drybrush only after the previous layer is fully dry.
• Use a dedicated old brush; drybrushing destroys fine tips.
• Build highlights in two or three light passes, not one heavy one.

Mistake 5: Ignoring scale and contrast when choosing colors

Symptom: the miniature looks flat or hard to read from across the table, even though the paint job is technically clean. Cause: colors are too similar in value, or the palette is too dark for a small figure. Corrective action: increase contrast between the deepest shadows and the brightest highlights, and pick a lighter mid-tone than you think you need. Small figures benefit from exaggerated value shifts because the eye reads them at a distance.

This is where D&D miniature painting tips differ from display painting. A tabletop figure needs to read clearly under game-store lighting, so push the contrast further than feels natural up close. If you are painting a Nolzur's figure with a lot of similar browns or grays, choose one accent color for the face, weapon, or cloak to anchor the eye. If you cannot see the silhouette from three feet away, the contrast is not finished.

• Squint at the figure to check value contrast.
• Reserve your brightest color for the focal point.
• Photograph the figure in black and white to spot flat areas.

Mistake 6: Sealing too soon or with the wrong product

Symptom: the varnish turns cloudy, pools in recesses, or leaves a frosted look. Cause: spraying in high humidity, applying too thick a coat, or using a gloss varnish where matte is needed. Corrective action: shake the can well, spray in thin passes from 8 to 12 inches away, and avoid humid or cold conditions. If frosting appears, a thin coat of gloss varnish can sometimes clear it, but prevention is far easier.

Sealing protects your work, but it is also a point of no return for some finishes. Test your varnish on a spare figure or a painted piece of sprue first. If you plan to handle the miniature often, a gloss coat followed by a matte coat gives durability without shine. Stop before you add a third or fourth coat; excess varnish will fill detail and look milky over time.

• Spray in thin passes, never one heavy coat.
• Avoid sealing in high humidity or direct sunlight.
• Test varnish on a spare piece before committing.

Diagnosis: symptom, cause, fix, and when to stop

• Visible brush strokes and clogged detail: Cause: paint applied too thick or too thin. Fix: strip with isopropyl alcohol if dried thick, then repaint with two thin coats. Stop if the detail is already filled and stripping would damage the primer. Thin your paint to skim-milk consistency before the next coat.
• Dirty, glossy, or stained shading: Cause: too much wash or a wash too dark for the base. Fix: wick away pools immediately, or re-layer the base color on raised areas. Stop if the wash has dried tacky; let it cure fully before adding anything. Use less wash and wick the excess before it dries.
• Chalky or scratchy highlights: Cause: overloaded drybrush or drybrushing over wet paint. Fix: wipe the brush almost dry and build up slowly, or switch to edge highlighting. Stop if the surface texture is already rough; a thin glaze may help, but heavy texture is hard to reverse. Drybrush with almost no paint, or use a fine brush instead.
• Cloudy or frosted varnish: Cause: spraying in humidity or applying too thick a coat. Fix: spray thin passes in dry conditions; a thin gloss coat can sometimes clear frosting. Stop if the frosting is heavy and has cured for days; another coat will likely make it worse. Test varnish on a spare piece before sealing a finished figure.

Products that help you avoid these mistakes

• D&D Nolzur's Marvelous Miniatures: Giant Dragonfly: Comes with a highly detailed figure, primed and ready to paint out of the box, with deep cuts for easier painting. The factory primer and deep cuts reduce prep time, so you can focus on thinning paint and controlling wash instead of priming from scratch.
• D&D Nolzur's Marvelous Miniatures - Female Human Barbarian: Features a highly detailed figure, primed and ready to paint, with deep cuts for easier painting. A single character model is a low-risk way to practice contrast and layering before you commit to a larger monster.
• Pathfinder Deep Cuts: Giant Eagle: Comes with a highly detailed figure, primed and ready to paint, with little to no assembly required and deep cuts for easier painting. Minimal assembly means fewer gaps to fill and fewer mold lines to chase, which removes two common sources of painting problems.

Most miniature painting problems come down to prep, paint consistency, and patience. Fix the cause rather than layering more paint on top, and know when a figure is better stripped or replaced than rescued. With a little practice, these common mistakes become easy to spot before they happen.
