How to Dry Brush Models: Technique, Brushes and Paint for Raised Detail

What dry brushing does

The technique works because paint only transfers to the highest points of a surface. When the brush has very little paint and you move it lightly across the model, the bristles skim the raised detail and leave the recesses dark. That creates contrast: edges look brighter, recesses stay in shadow, and fine detail stands out without any fine brush work.

It suits textured areas best: rough-cast armor, chipped metal, engine detail, cloth folds, rock bases and groundwork. It is less suited to perfectly smooth, glossy surfaces, where a dry-brush effect can look chalky or scratchy. Used with restraint, it adds a worn, natural look that makes a model feel more real.

Brush and paint choices

Use a flat or round brush with stiff bristles, and keep one just for this job, because dry brushing wears brushes out quickly. A cheap synthetic brush with a blunt tip is fine, and old brushes that no longer hold a point often find a second life here. Brush size should match the area, with a larger brush for big panels and a smaller one for details.

Pick a paint lighter than the base color for highlights, and one that has good pigment coverage. Acrylic hobby paints are common for this technique, as they dry quickly and clean up easily, though enamels and oils also work. Thick, opaque paint from the jar usually works better than thinned paint, because thinned paint tends to flow into recesses and ruin the effect.

Step by step

Put a small amount of paint on a palette or paper towel. Dab the tips of the bristles in it and then wipe the brush back and forth on a paper towel until almost no paint seems to come off. The brush should leave only a faint trace when you test it on the towel. If it leaves a solid stroke, it is still too wet.

Now drag the brush lightly across the model in short strokes, ideally in a direction that crosses the raised detail instead of running along it. Build up color slowly with several passes rather than one heavy pass. Stop and look often. Adding more is easy; removing too much is not. Many builders go from a mid-tone to a lighter highlight on only the sharpest edges for depth.

Prepare the surface first

Dry brushing works best on a stable, dry base coat. Prime and paint the model first, and let it cure fully so your brush does not lift the base paint. A satin or matte base gives the brush a bit of tooth to grab. If the surface is glossy, the paint may slide off or look patchy.

Seal the finished work with a clear coat to protect it from handling. Test the clear coat on a scrap piece first, because some sprays can dull or darken dry-brushed effects. Wear a respirator or work in a ventilated area when you spray, and follow the product's safety information.

Using dry brushing in weathering and scenery

On vehicles and aircraft, dry brushing can show worn edges where paint would naturally rub away, such as hatches, handles, track edges and leading edges. Use a metallic or lighter color for a worn-metal look, but keep it subtle, since too much looks like fake damage. Combining it with a wash or pigments adds depth.

For dioramas, dry brushing brings out rock textures, bricks, wood grain and groundwork. Start with a dark base, add a mid-tone, and finish with a light highlight on the high points. Our guides to weathering sets and diorama supplies cover related materials you may find useful with this technique.

Common mistakes

The most common mistake is too much paint on the brush. If the result looks chalky, blotchy or like the paint has simply been brushed on, wipe more off the brush. Another is pressing too hard; dry brushing needs a light touch, and heavy pressure flattens bristles and pushes paint into recesses.

Others include using a brush that is too small for the area, working on tacky paint and highlighting too much. If you overdo it, you can often repaint the base color and try again. Practice on spare parts or an old kit before the build you care about most.

A good habit is to test the effect on a spare part from the same kit before touching the finished area. Each paint and brush combination behaves a little differently, and a quick trial shows how much paint to leave on the bristles and how many passes you need. It also lets you compare two highlight colors side by side and choose the one that looks most natural under your own lighting.

Frequently asked questions

Do I need a special brush? No, but a stiff, cheap brush kept for dry brushing is ideal, as the technique wears bristles. Can I dry brush with thinned paint? It is better to use paint straight from the jar or palette. Thin paint flows into recesses and defeats the technique.

What color should I use? A lighter shade of the base color, or a metallic for worn edges. Keep the contrast gentle for a realistic look.

Does dry brushing work on smooth plastic? It works best on textured or raised detail. On very smooth surfaces it can look uneven, so practice first.
