Liquitex Professional High Gloss Varnish 946ml - Mirror-Like

In this review the Liquitex Professional High Gloss Varnish 946ml is assessed as a studio-grade finishing medium for acrylic painters who need a durable, high-gloss seal. The bottom line: it is best for artists who want a non-yellowing, water-based varnish that dries to a hard, glossy surface and enhances color depth. The review finds it especially useful where archival permanence and a mirror-like sheen are priorities.

Key Features

• Archival and permanent: The varnish is formulated to be permanent and non-removable, providing long-term protection for finished paintings.
• High-gloss finish: Produces a clear, mirror-like gloss that brings out richer color and deeper contrast in both acrylic and mixed media work.
• Low-odor, water-based: The medium uses water-based technology so it is easier to use indoors and conforms to ASTM D4236 for safe classroom and studio use.
• Durable, non-tacky film: Dries to a hard, flexible, non-tacky surface that resists dirt and handles normal handling once cured.
• Intermixable with Liquitex paints: Can be blended with Liquitex Professional acrylic paints and mediums to adjust sheen or application properties.

Who It's For

Artists working in acrylics on canvas, panel or wood who want a high-gloss, archival finish will find this varnish a reliable choice. It is well suited to studio painters, instructors and advanced students who need a varnish that resists yellowing and protects pigments from UV exposure.

Those who prefer removable or matte finishes should look elsewhere; the Liquitex archival formula is permanent and designed specifically for a glossy, long-lasting coating rather than a low-sheen or reversible option.
