Acrylic Plasticator Thin 30 ml, VALLEJO Ammo — solvent-free acrylic thinner for plastic model paints

VALLEJO Ammo Acrylic Plasticator Thin 30 ml is a water-based, solvent-free acrylic thinner designed to improve the application of acrylic paints on plastic model kits. Formulated to reduce surface tension and viscosity, this thinner helps paints flow evenly, minimize brush strokes and promote better adhesion on plastic substrates. The 30 ml bottle provides a small, controlled quantity suitable for both brush and airbrush use when adjusting paint consistency for detailed modelling work.

Advantages

This acrylic thinner is solvent-free and water-based, reducing the risk of damaging delicate plastic parts while maintaining paint integrity. It improves leveling and flow, helping to eliminate brush marks and surface irregularities. The product is formulated specifically for plastic model paints, allowing for smoother coats and improved adhesion without altering the paint’s colour or finish when used in appropriate proportions.

Suitable for

• Thinning acrylic paints for brush application on plastic model kits
• Adjusting viscosity for airbrushing on plastic miniatures and scale models
• Improving flow and leveling on small plastic parts and detailed areas

Key specifications

• Formulation: water-based, solvent-free acrylic thinner
• Volume: 30 ml bottle
• Compatibility: designed for acrylic model paints used on plastic substrates
• Effect: reduces surface tension and viscosity to improve flow and leveling
• Application methods: suitable for brush and airbrush when reducing viscosity is required

How to use

Begin by shaking the bottle gently to ensure a uniform mixture. Add small amounts of the thinner to your acrylic paint incrementally, mixing thoroughly until the desired consistency is reached. For brush work, aim for a smoother, more flowing consistency that reduces visible brush marks. For airbrushing, dilute gradually and test spray on a surface to adjust flow and atomization; avoid over-thinning. Always use clean containers and tools when mixing to prevent contamination and ensure consistent results.

Usage recommendations

Use sparingly and test on a scrap plastic piece before applying to a finished model. Work in a well-ventilated area and follow standard model-paint handling practices. When switching between paints or application methods, clean brushes and airbrush components thoroughly to maintain performance and avoid buildup. Store the bottle upright and tightly closed at room temperature away from direct sunlight.
