MCTRHG Clear Acrylic Paint Sealer — High Gloss Varnish
Best for vibrant acrylics and mixed-media projects, this crystal-clear, wet-look gloss seals and protects finished paintings. It provides a permanent protective layer that intensifies color depth without clouding or dulling the surface. The formula resists yellowing, fading, and UV exposure, helping art stay vivid over time. It dries with a glass-like shine and self-levels to minimize brush marks, bubbles, or sticky residue, making it ideal for canvases, rock painting, and models.
Who it’s best for: painters seeking a bright, high-gloss finish with strong surface protection, especially on acrylics and non-porous surfaces. Choose this if you want a single-coat look with minimal cleanup and a deep, reflective finish.
Limitations: as with many waterborne varnishes, it requires proper surface preparation and adequate drying space to prevent dust adherence and issues with tackiness if applied too thickly.
Liquitex BASICS Gloss Varnish — 250ml
This permanent gloss varnish protects finished paintings while preserving color integrity. It dries clear and non-yellowing, maintaining a crisp sheen over time. A practical feature is that gloss can be mixed with matte varnish to customize the final appearance, offering flexibility for artists who want to toggle between finishes without buying separate products.
Who it’s best for: artists who want a reliable, mid-range gloss option with the option to tailor sheen levels by blending with matte varnish. It’s a solid all-around choice for canvases, paper, and mixed-media work.
Limitation: blending requires careful testing to achieve the desired final sheen and consistency, especially on larger surfaces.

Who it’s best for: artists seeking an effortlessly glossy, durable finish with excellent clarity for diverse media, including metallic and gold-toned acrylics. Choose this if you want a robust varnish that keeps colors vibrant and prevents crazing.
Caution: as with high-gloss finishes, apply thin, even coats to avoid forming streaks or air bubbles on textured surfaces.

Who it’s best for: hobbyists and professionals working on models, miniatures, or mixed-media pieces needing a clear, durable gloss that holds up to handling. This is a strong pick for airbrush or brush applications and outdoor or indoor use depending on prep.
Limitation: the gloss intensity can vary slightly with application method and surface texture, so surface tests are recommended before large projects.

Buying Guide
What should you consider when choosing a high gloss varnish?
- Surface compatibility: Confirm the varnish is recommended for your base surface (canvas, wood, metal, plastic, etc.).
- Gloss level and finish: Decide between ultra-gloss, standard gloss, or a mixable option to tailor sheen to your piece.
- Drying time and cure: Look for fast-drying formulas if you’re working on multiple layers, but ensure proper ventilation and dust-free conditions.
- UV resistance and yellowing: For works exposed to light, prioritize UV-stable, non-yellowing formulations to maintain color accuracy.
- Ease of application: Self-leveling formulas reduce brush marks; brushes, spray, or airbrush compatibility can influence workflow.
- Safety and cleanup: Check for non-toxic claims if you work with children or in shared spaces; water-based products generally clean up with soap and water.
