SlapChop Airbrush Kit — Official Product

No, you must thin all acrylic miniature paints before airbrushing to prevent clogging the 0.3mm nozzle. Mix your paint with airbrush thinner, flow improver, or distilled water to a milk-like consistency—typically a 1:1 ratio for most brands.

Test your mixture by letting it drip off your stirring stick. It should flow in a steady stream rather than thick drops. Primers designed specifically for airbrushing (like Vallejo Surface Primer) often require less thinning than standard bottle paints.

Start by priming your model with black paint at 20-25 PSI from 6-8 inches away, using broad side-to-side strokes for even coverage. Once dry, load white or light gray paint and reduce your distance to 4-6 inches.

Hold the airbrush at a 45-degree angle above your model and apply highlights to surfaces that would catch overhead light—tops of helmets, shoulders, and raised weapon details. Build the highlight gradually with multiple light passes rather than one heavy coat. The dual-action trigger on the slapchop airbrush lets you control paint flow independently from airflow, so you can feather the edges where white transitions to black.

Immediately after finishing, empty any remaining paint from the cup and wipe it with a paper towel. Fill the cup about 1/4 full with airbrush cleaner or distilled water, then spray it through the airbrush into your cleaning station until the liquid runs clear.

Remove the needle by loosening the needle chucking nut at the rear of the airbrush and gently pulling it straight out. Wipe the needle with a cleaner-dampened cloth from back to front (never front to back, which could bend the tip). Use the included interdental brushes to clean inside the nozzle cap and paint cup threads. Reassemble and spray a final burst of cleaner to flush the air channels.

Yes, the 0.3mm needle strikes the ideal balance for miniature painting. It’s precise enough for highlighting individual armor panels and weapon details, while covering infantry-sized models quickly during base coat application. You’ll handle everything from 28mm tabletop miniatures to larger vehicle models with this single needle size.

If you later want to specialize, our 0.2mm needle excels at extremely fine edge highlighting and facial details, while the 0.5mm needle accelerates terrain and large vehicle priming. Most painters find the 0.3mm setup handles 90% of their airbrushing needs.

Absolutely—the slapchop airbrush handles Citadel Contrast Paints beautifully when properly thinned. Mix your Contrast paint with Contrast Medium at a 2:1 or 3:1 ratio (paint to medium) depending on how transparent you want the layer. Apply it at 18-22 PSI over your zenithal-primed model.

The pre-shaded highlights you create with the airbrush will show through the translucent Contrast paint, giving you instant depth and shadow definition. This is the core of the slapchop technique—building value with the airbrush, then adding color with Contrast paints in a fraction of the time traditional layering requires.

For priming and base coating, set your pressure regulator to 20-25 PSI and maintain a 6-8 inch distance from your model. This gives you fast coverage with minimal overspray. When applying zenithal highlights, increase to 25-30 PSI but move closer (4-6 inches) for more concentrated coverage on raised details.

For fine detail work and edge highlighting with thinned regular paints, reduce pressure to 15-18 PSI and work 3-4 inches from your target. Lower pressure gives you more control and reduces the risk of paint pooling in recessed areas. Always test your spray pattern on scrap material when changing pressure or paint types.
