Learn to apply AK11151 Brownish Green on Gunpla kits using brush or airbrush. This guide covers preparation, thinning, and common mistakes for a smooth military green finish.
Quick answer
To paint with AK11151 Brownish Green on Gunpla, thin it with water or acrylic thinner for brush painting (about 2:1 paint to thinner) or with AK Interactive's own thinner for airbrushing (around 1:1.5 ratio), and apply in thin, even coats.
Why AK11151 Brownish Green works for Gunpla
This military green hue is a versatile choice for realistic Gundam schemes, especially Zeon or ground-type mobile suits. The AK11151 Brownish Green from AK Interactive is an acrylic paint that comes in a 17ml bottle with a clear label and reference code, making it easy to identify. Its matte finish suits scale-model looks, but you need to prepare the surface properly to avoid adhesion issues on bare plastic.
Brush vs. airbrush: trade-offs
Brush painting AK11151 Brownish Green is straightforward and requires minimal setup, but you'll need multiple thin coats to avoid brush strokes. Airbrushing gives a smoother, more even finish, especially for larger parts, but demands proper thinning and cleaning. For small details like panel lines or accents, a brush works fine; for full armor panels, an airbrush is better.
Step-by-step painting guide
- Step 1: Prepare the surface: Clean the Gunpla parts with warm soapy water to remove mold release agents. Lightly sand with 600-800 grit sandpaper for better paint adhesion. A primer (gray or white) is recommended for this military green to ensure color consistency. Skipping primer can cause the paint to chip or look uneven, especially on bare plastic.
- Step 2: Thin the paint: For brush painting, mix AK11151 Brownish Green with water or acrylic thinner in a 2:1 ratio (paint to thinner). For airbrushing, use AK Interactive's own thinner at a 1:1.5 ratio (paint to thinner) and test the consistency on a spoon—it should flow like skim milk. Over-thinning makes the paint run; under-thinning clogs the airbrush or leaves brush marks.
- Step 3: Apply thin coats: Brush: use a flat brush and apply in one direction, letting each coat dry for 10-15 minutes. Airbrush: spray at 15-20 PSI from 6-8 inches away, using light passes. Build up 2-3 thin coats for full opacity. Thick coats trap brush strokes or cause drips. Patience between coats is key.
- Step 4: Clean up and cure: Clean brushes with water or acrylic cleaner immediately. For airbrushes, flush with thinner until clear. Let the paint cure for 24 hours before masking or applying decals. Dried paint in the airbrush nozzle is hard to remove—clean right after use.
