Gloss Pouring Medium 64oz Half Gallon - Improves Flow & Gloss

In this review the U.S. Art Supply 64 fl. oz. gloss pouring medium is examined for painters who work with acrylic pours and fluid techniques. The bottom line: it is aimed at hobbyists and serious acrylic artists who need a glossy, clear medium that adjusts viscosity and improves flow without altering color or adhesion. The reviewer found it especially useful when creating cells and smooth pours, and notes the product dries with a lasting shine while conforming to safety standards, making it a practical choice for studio work.

Key Features

• Large volume: The 64 fl. oz. half-gallon size provides enough medium for multiple large pours or many smaller experiments, reducing the need for frequent repurchase.
• Gloss finish: The clear gloss formula enhances color vibrancy and leaves a high-shine finish that helps poured paintings look more vivid and finished.
• Viscosity control: It acts as a viscosity adjuster to improve flow and help create cells and smooth transitions when mixed with acrylics or fluid pigments.
• Stable dries: The medium is formulated to prevent cracking, fading, and separation so finished pours remain consistent as they cure.
• Ready to pour: Designed to mix directly with pouring paints to reach the desired consistency without significantly slowing drying time.
• ASTM D4236 compliant: Non-toxic and labeled to standards that make it suitable for classroom and studio use.

Who It's For

Artists who regularly create acrylic pour art, whether on canvas, wood, or mixed surfaces, will appreciate the volume and glossy finish; the medium particularly benefits painters who want prominent cell effects and smoother flow. Those working on larger pieces or producing many pours will value the half-gallon size and consistent performance.

Beginners experimenting with pouring can use this product, though novices who prefer thinner, faster-mixing additives may find it slightly thicker to integrate at first. If you require an ultra-fast-drying glazing medium or very high-impasto texture, consider a product specifically formulated for those techniques instead.

Pros & Cons

Pros

• Delivers a clear, glossy finish that enhances color and final presentation.
