GOLDEN Airbrush Medium Acrylic Thinner 237 ml — 100% Acrylic, Low-Viscosity for Improved Atomization

GOLDEN Airbrush Medium 8oz is a 100% acrylic polymer additive that thins and improves airbrush flow while reducing clogging and surface tack.

This medium is formulated to modify acrylic paints for airbrushing and delicate masking work. It lowers viscosity without significantly weakening the film, improves atomization, and helps frisket or masking film lift more cleanly. The water-based formula dries to a flexible, UV- and water-resistant film and is packaged in an 8-ounce bottle made in the USA. Note: not for use with GOLDEN airbrush colours or varnish.

How does GOLDEN Airbrush Medium reduce clogging in an airbrush?

The medium thins acrylic paints to a consistency that atomizes more evenly, which lessens the buildup inside nozzles and needles during spraying. Because it maintains acrylic binder integrity, it helps preserve film strength compared with solvent thinners.

• 100% acrylic polymer dispersion maintains binder cohesion.
• Optimised viscosity for finer atomization and fewer blockages.
• Compatible with many acrylic paints for airbrush thinning (avoid GOLDEN airbrush colours and varnish).

Will this medium affect paint durability or flexibility?

The dried film remains flexible and resists water and UV exposure due to the acrylic polymer base. It is designed to thin while keeping the cured paint film resilient, rather than creating a brittle or powdery finish.

• Dries to a flexible film suitable for wearable surfaces like clothing.
• Improved water and UV resistance compared to simple water thins.
• Preserves adhesion and film integrity for layered work.

Can I use GOLDEN Airbrush Medium on fabric and prepared surfaces?

Yes — the product performs well on textiles and surfaces where flexibility and wash resistance are important. It facilitates smoother application and makes masking/frisket removal easier, but always pretest for laundering and adhesion on your specific fabric.

• Works well on clothing when paired with appropriate fabric-prep and fixatives.
• Makes frisket and masking film less tacky for cleaner edges.
• Recommended to test fabric samples for washfastness before full application.

How much should I add and are there any compatibility limits?

Start with small increments and mix until you reach the desired sprayability; the right ratio depends on paint brand and nozzle size. Avoid using this medium with GOLDEN airbrush colours or varnish as directed by the manufacturer.

• Begin with 10–30% medium by volume and adjust as needed.
• Test spray on paper or scrap material to dial in pressure and flow.
• Not compatible with GOLDEN airbrush colours or GOLDEN varnish products.

Who is this for: GOLDEN Airbrush Medium 8oz is aimed at artists and makers who airbrush acrylics and need improved atomization, reduced nozzle clogging, and easier frisket removal without sacrificing film flexibility. It's especially useful for illustrators, textile artists, prop makers, and hobbyists seeking a water-based thinning solution that keeps cured paint flexible and weather-resistant. Always patch-test on your chosen substrate and observe manufacturer warnings about incompatible GOLDEN airbrush colours and varnishes.
