Vallejo Permanent Acrylic Varnish Glossy Finish
The Vallejo Permanent Acrylic Varnish is a water-based gloss varnish designed to protect canvases, primed wood, metal, resin, and other varnishable surfaces. It dries quickly, remains highly transparent, and offers excellent flexibility. Its strong hardening properties provide weather resistance, suitable for interior and exterior use. UV-resistant and highly scratch-resistant once cured, it can be applied directly over the final dry coat of a miniature or diorama. The finish intensifies colors while offering protection against scratches, wear, and dust. Suitable for airbrush or brush application, this varnish is part of a trio with gloss, matte, and satin options for varying project needs.
Features include fast drying, strong film formation, and non-yellowing properties. This makes it a reliable choice for figures exposed to handling, gaming tables, or outdoor displays where color integrity and surface protection matter. Use care when applying to avoid excessive buildup; thin coats yield the best results, and allow ample drying between passes for a uniform gloss.
Vallejo Polyurethane Varnish Gloss Finish 60 ml
This high-performance polyurethane varnish delivers a strong, protective layer with a durable glossy finish. It’s tailored for miniatures, models, and dioramas, safeguarding paintwork against wear and fading. The coating forms a tough, flexible shield that resists scratches, chipping, dust, and moisture, making it ideal for high-contact gaming figures. It dries quickly and yields a smooth, non-yellowing gloss that enhances vibrancy. It’s particularly suited for armor, metallics, and other areas where intense color depth is desired without sacrificing protection.
Consider application conditions: ensure surfaces are clean and dry, apply in thin passes, and allow full cure before handling. The gloss coat typically requires careful layering to avoid puddling and to maintain a crisp finish on delicate details. This is a reliable option when a vivid, high-sheen look is part of the project’s aesthetic.
The Army Painter Anti Shine Matt Varnish
The Army Painter Anti Shine Matt Varnish is an acrylic, non-toxic product formulated to remove brightness from models prepared with Quickshade or conventional paints. This matte varnish dries quickly and preserves the underlying color without adding gloss. It is designed for thin, even coats, and is best applied after Quickshade has dried for at least 48 hours. Users should avoid humid or cold conditions and test on a small model first. The result is a muted, realistic finish that reduces glare on metallics and plate armor while maintaining definition in sculpted details.
Use this product when you need a non-gloss, natural look on figures intended for tabletop play or display where reflections could obscure details. It complements metallics by reducing shine while keeping a consistent protective layer against handling and dust.
Vallejo Polyurethane Varnish Satin Finish 60 ml
The Vallejo Polyurethane Varnish Satin provides a balanced finish that blends protection with a subtle sheen. This varnish forms a durable layer that resists scratches, dust, and moisture while maintaining a soft, less reflective surface ideal for battle-worn or natural-looking miniatures. It is fast-drying and non-yellowing, with the durability benefits of a polyurethane sealant. The satin effect is particularly suitable for figures with leather, fabric, or wood textures where a moderate gloss would be visually distracting.
Impending war game sessions or long-term display scenarios benefit from the satin finish’s ability to preserve color depth without overpowering detail. Application is straightforward via brush or airbrush, with thin coats recommended to avoid clouding or an uneven finish on textured surfaces.
Vallejo Acrylic Gloss Varnish Spray
This spray varnish offers a simple mode of use with a thin layer that dries quickly to a high-gloss, UV-resistant finish. It’s designed for a wide range of surfaces, including canvas, primed wood, metal, and resin, with excellent flexibility. The spray range includes glossy, matte, and satin options, making it a flexible choice for quick-finish projects or touch-ups. Proper ventilation and distance (about 40 cm) from the paint surface are recommended for an even coat. Multiple coats can be applied when completely dry to achieve the desired level of gloss.
Spray varnishes are convenient for large miniatures or dioramas where brushmarks must be avoided. They are especially valuable when a consistent, glassy shine is part of the aesthetic, or when layering over metallics to enhance their luster without adding texture from brushwork.
GRANOTONE Clear Coat Acrylic (2-Pack) High Gloss & Matte
GRANOTONE offers a two-pack of clear coats in gloss and matte finishes, designed for general-purpose protection of professional and hobbyist artworks. The gloss provides a crystal-clear sheen that highlights color depth and detail, while the matte option delivers a non-reflective finish ideal for subdued displays. The products are marketed as non-yellowing and non-toxic, with a focus on anti-crazing properties to preserve the integrity of acrylic art. This pack is suitable for artists seeking flexibility in a single purchase, particularly for mixed-media pieces or varying display environments.
Consider compatibility with different paints and substrates; always test on a small area to ensure proper adhesion and finish. The dual-pack setup supports experimentation with both high-gloss and matte looks in the same project or across multiple projects.
Buying Guide: Key Purchase Considerations
When selecting a clear coat for miniatures, consider these factors to match your goals and workflow:
- Finish type: Gloss enhances color depth and protection, matte reduces glare and emphasizes details, and satin offers a balanced look. Choose based on the model’s aesthetic and the display environment.
- Form factor: Sprays are quick and uniform but require ventilation and distance control. Brush- or airbrush-applied varnishes offer precision but may require thinning and multiple passes.
- Durability: Polyurethane-based varnishes typically provide stronger protection against handling, humidity, and wear. Water-based acrylics are easier to clean and less toxic, with good flexibility.
- Yellowing resistance: Look for non-yellowing formulas designed to preserve original colors over time, especially on light or white surfaces.
- Application conditions: Temperature, humidity, and drying time influence results. Thin coats and adequate curing between layers reduce clouding and week-long curing times.
- Substrate compatibility: Ensure the varnish adheres well to plastic, resin, metal, wood, and other common miniature materials. Some products are suitable for direct application onto dried finishes, while others require priming.
- Finish versatility: If you work across multiple projects, a versatile set (gloss and matte options) can be more economical and convenient for future needs.
- Health and safety: Consider non-toxic formulations and proper ventilation, particularly for spray coatings and indoor use.
The selections above provide options across finishes, application methods, and project scales. For high-traffic figures or outdoor displays, polyurethane-based gloss or satin coatings tend to offer superior protection. For display pieces where color fidelity and visibility of miniature details are paramount, a clear gloss or a dual-pack with a matte option can balance protection with realism. Always conduct a small test before committing to a full application to verify adhesion, cure time, and final appearance.
