Liquitex Professional Gloss Fluid Medium 946 ml (32 oz) — increases gloss, improves flow

Liquitex Professional Gloss Fluid Medium is a clear, water-based acrylic medium that boosts colour intensity, increases gloss and transparency, and improves paint flow without compromising flexibility.

Use this 32-ounce (946 ml) gloss fluid medium to thin acrylic paints while preserving pigment strength and adding a durable, non-tacky sheen. Designed to mix seamlessly with Liquitex Professional acrylic paints and other Liquitex mediums, it helps you achieve glazes, smooth pours, and high-gloss finishes with reliable archival properties. Conforming to ASTM D4236 and non-toxic, it’s suitable for classroom and studio use.

How does this medium change paint handling and finish?

When blended with acrylic colour, the fluid medium reduces viscosity so paint flows more easily and levels smoothly. It also increases transparency and imparts a glossy surface without making the film brittle, allowing layered glazing techniques and luminous colour effects.

• Thins paint for smoother brushstrokes and pour work
• Enhances colour depth while increasing transparency
• Dries to a hard, flexible, non-tacky gloss finish
• Improves leveling and reduces visible brush marks

Can I mix it with other Liquitex products and acrylic paints?

Yes — this fluid medium is formulated to intermix with Liquitex Professional acrylic paints and a wide range of Liquitex mediums. Compatibility ensures consistent drying behavior and film characteristics across mixed systems.

• Works with Liquitex Professional paint colours and mediums
• Maintain archival quality when combined correctly
• Use small test mixes when combining with non-Liquitex materials
• Ideal for glazing, transparent layers, and flow techniques

What are the safety and practical handling notes?

The medium is water-based, lightweight, and labeled non-toxic, making it suitable for educational and studio environments. Clean brushes and tools with soap and water while the medium is wet; cured films are durable and flexible but avoid extreme solvent contact.

• Conforms to ASTM D4236 for educational use
• Wash tools with water before drying
• Store capped, upright, away from freezing temperatures
• Test adhesion on prepared surfaces before large applications

How should I use it to achieve best results?

Start by mixing small ratios into your acrylic colour to find the balance of transparency and flow you want. For glazes, use higher proportions of medium to paint; for slight sheen and smoother handling, add just enough to improve flow without overly thinning pigment strength.

• Begin with 10–30% medium by volume and adjust as needed
• Layer multiple thin glazes rather than one heavy coat
• Allow adequate drying time between layers for clarity
• Use for pours, airbrush thinning, or to extend working time

Who is this for: Liquitex Professional Gloss Fluid Medium suits artists, instructors, and hobbyists who want to increase gloss and transparency in acrylic work while improving flow and leveling. It’s ideal for painters exploring glazing techniques, mixed-media creators needing a reliable clear medium, and educators seeking a non-toxic, classroom-ready fluid medium in a generous 946 ml size.
