Liquitex Professional Matte Super Heavy Gel Medium, 32-oz - Stiff

In this review the Liquitex Professional Matte Super Heavy Gel Medium is examined for artists who need a very thick, non-yellowing medium that produces a matte, oil-like texture. The bottom line: this 946ml jar is best for painters and mixed-media makers who want strong body and high surface drag to build impasto, transfers or textured craft surfaces, while maintaining durability and water resistance once dry. It is a professional-grade choice that mixes with Liquitex acrylics and extends workable time compared with thinner films.

Key Features

• Matte finish: Dries to a translucent matte surface that reduces shine while preserving the look of layered color.
• Extra heavy body: Very dense with high surface drag, offering a stiff, oil-paint-like feel for pronounced impasto and textured strokes.
• Large 946ml jar: The 32-oz container provides plenty of medium for extended projects or classroom use without frequent repurchasing.
• Mixes with Liquitex paints: Intermixable with Liquitex Professional Acrylic Paint Colors and Mediums to alter body, transparency and adhesion.
• Durable and safe: Non-toxic, conforms to ASTM D4236, and dries to a water-resistant, non-yellowing surface suitable for educational settings.

Who It's For

This medium is aimed at professional and serious hobbyist painters who work with heavy textures, impasto techniques, or mixed-media transfers and need a reliable, stiff gel that holds peaks and brush marks. It also suits educators and craft studios that require a large, safe jar that conforms to ASTM standards.

Less suitable are artists who prefer high gloss finishes, very fast-drying films, or those who need a fluid glazing medium; for those uses a thinner or gloss medium would be a better match.

Pros & Cons

Pros

• Provides a stiff, oil-like body that holds texture and brush strokes for sculptural acrylic effects.
• Dries to a stable, water-resistant and non-yellowing surface for long-term durability.
• Large 32-oz size and professional-grade formulation deliver value for frequent users and classrooms.
• Intermixable with Liquitex acrylic paints and mediums so it integrates into established workflows.

Cons

• Very dense consistency can be hard to spread thinly and may require tools like palette knives or sponge brushes for even application.
• Drying time is longer than thin films, and some users report variation in how quickly it hardens depending on layer thickness.
