AK Interactive 3rd Gen Thinner 100ml – Acrylic Model Paint Thinner for Airbrush & Brush, Smooth Flow

AK Interactive 3rd Gen Thinner 100ml is a purpose-formulated acrylic thinner that improves airbrush flow and brush handling for model paints without affecting pigment performance.

This 100 ml thinner from AK Interactive is engineered to deliver consistent viscosity for acrylic hobby paints, reducing airbrush clogging and helping achieve smoother, more controllable sprays and brush strokes. It’s compatible with most acrylic model paints and is designed for both airbrush and conventional brush use. Use it to fine-tune paint viscosity for detailed work, to extend open time, and to promote even atomization through the nozzle.

How does this thinner help prevent airbrush clogging?

The formula reduces surface tension and improves flow so paint passes through the nozzle more smoothly, lowering the risk of spatter and blockages. Properly thinned paints atomize more evenly, producing steadier sprays and finer detail.

• Optimizes paint viscosity for consistent atomization
• Minimizes spluttering and nozzle build-up
• Works with multiple AK and lacquer-safe acrylic formulations

Can I use AK Interactive 3rd Gen Thinner with a brush as well as an airbrush?

Yes — it’s formulated to improve brush flow and leveling without breaking pigments. When added sparingly, it helps eliminate brush marks, extends drying time slightly, and makes paints easier to lay down on small parts.

• Add small amounts to maintain coverage while improving spread
• Helps achieve smoother transitions on scale models and miniatures
• Safe for touch-ups and delicate detailing when used correctly

How much thinner should I mix for different applications?

Mix ratios depend on paint brand, nozzle size and desired finish; start conservatively and adjust. For general airbrushing begin at about 10–30% thinner by volume, increasing for finer nozzles or very viscous paints. For brushing, use minimal amounts until you reach the desired flow.

• Airbrush (general): 10–30% thinner by volume as a starting point
• Fine-detail airbrush/nozzle: increase ratio gradually for better atomization
• Brush work: add small drops until flow and coverage suit the task

How should I store and maintain my thinner and tools?

Keep the bottle sealed tightly and stored in a cool, ventilated area away from direct heat and flames. Use appropriate cleaners like AK Perfect Cleaner AK119 for final tool maintenance, and always follow safety guidance on the label for handling and disposal.

• Close cap after each use to prevent evaporation and contamination
• Store upright in a cool, well-ventilated area away from ignition sources
• Clean airbrushes with AK119 or compatible cleaners after use

Who is this for: Modelers, miniature painters and hobbyists who want predictable, clog-free airbrush performance and improved brush flow will appreciate AK Interactive 3rd Gen Thinner 100ml. It’s suited to those working on scale kits, figures, dioramas and other detailed projects who need an effective thinning solution compatible with acrylic model paints and professional hobby workflows.
