You’ve spent dozens of hours edge-highlighting your latest squad, and the last thing you want is for that effort to be undone by dust, skin oils, or the dreaded friction of a transport case. The question of whether to varnish is one of the most debated topics in the hobby, especially when moving models from the painting desk to a permanent display.
Pro Tip: The Finish Matters
Varnishing isn't just about protection; it's about control. A gloss varnish might protect well but can create distracting reflections. For stadium seating displays, a high-quality ultra-matte varnish is usually preferred to keep the focus on your paintwork rather than the light bouncing off it.
Why Varnish? The Defense Against the "Foam Case Burial"
If you still use traditional transport methods, you are likely familiar with "foam rub." This occurs when the movement of transit causes the foam to act like ultra-fine sandpaper against your models' highest points. Varnish creates a clear, durable layer that takes the brunt of this friction, saving your highlights.
When you move to a modular miniature display system, the physical handling of models decreases, but the environmental factors change. Varnish becomes your first line of defence against settling dust and the natural oils from your fingers when moving units during a game.
There's a slower enemy, too: light. The Canadian Conservation Institute notes that light damage to pigments is cumulative and proportional to intensity — running roughly 1,000 times faster in direct sunlight than at gentle display levels. A UV-resistant matt varnish slows fading, but it isn't a licence to sit models in a sunny window. The bigger win is using high-lightfastness paints, which can hold their colour for 50–100 years in normal indoor conditions, and keeping the display out of direct sun.
Matt, Satin, or Gloss: Which is Best for Showcase?
The finish you choose can drastically alter how your miniatures look under display lighting (compatible with systems like Warhammer 40,000® or Age of Sigmar®).
- Matt Varnish: The hobbyist favourite for display. It kills all light reflections, making it perfect for photography and ensuring every detail of your blend is visible.
- Satin Varnish: A middle ground that provides a slight "realistic" sheen to leather or skin without being as reflective as gloss.
- Gloss Varnish: Typically used for specific effects like wet blood, slime, or gems. Using this over a whole model often makes it look "toy-like" and can cause significant glare in glass cabinets.
Varnishing for Open Displays
Many painters worry that an open display will lead to ruined models due to dust. However, a varnished model is incredibly easy to maintain. Dust cannot "bond" to a sealed surface as easily as it can to bare acrylic paint.
When your army is arranged in a stadium seating layout, you can quickly use a soft makeup brush to sweep away dust without fear of chipping the paint underneath. To see how this compares to enclosed setups, read our guide on Acrylic Display Cases vs Open Stands.
Practical Tips for a Perfect Finish
Before you commit to varnishing your entire centrepiece army, keep these rules in mind:
- Check the weather: High humidity can cause "frosting," where the varnish dries with a white, cloudy texture.
- Multiple thin coats: One heavy coat can fill in fine details. Two thin coats are always safer.
- Maintenance: Even varnished models need occasional care. Check out our advice on keeping miniatures clean without dust-proof cases.
Frequently Asked Questions
Does varnish change the colours?
Varnish can slightly "deepen" the colours, often making them look more vibrant. Matt varnish can occasionally make very dark colours look slightly grey if applied too thickly.
Can I use varnish in an airbrush?
Yes, airbrushing varnish is often safer than using rattle cans as it gives you more control over the flow and reduces the risk of frosting or orange-peel texture.
Do I need varnish if I use high-cost acrylic alternatives?
Even inside a case, models can be handled or moved. Varnish is a low-cost insurance policy for any paint job you are proud of, regardless of your display choice.
