Quick answer: a thin brushed layer of acrylic miniature paint usually feels dry within a few minutes, so in a warm, dry room you can normally add the next layer after around ten minutes. Washes, one-coat speed paints, primers, dips and varnishes each take longer, and none of them is truly hard straight away: Vallejo says its model paints can need 48 hours or more to reach full adhesion and scratch resistance. Cold, damp rooms and thick coats slow everything down.
The short version is that there are two different "dry" times. Getting them confused is the cause of most lifted layers, fingerprints in fresh paint and cloudy varnish.
Touch dry and fully dry are not the same thing
Acrylic paint dries in two stages. Golden Artist Colors, which publishes detailed technical notes on acrylics, describes a first stage where a skin forms on the surface and the paint feels dry to the touch; very thin films can do this in seconds. The second stage is when all the water and other liquids have left the whole film, and only then do adhesion and hardness fully develop. For thin films that can take a few days.
On a miniature this means you can usually paint the next layer quite quickly, but handling, masking, gaming or packing the model away is safer once the paint has had a day or two. Vallejo's FAQ makes the same point: Model Color and Game Color seem dry to the touch very quickly, but optimum adherence and resistance to scratches may not be reached until after 48 hours or more.
Drying times by painting stage
These are the figures manufacturers and testers actually publish. Treat them as a starting point, because your room temperature and humidity will move them.
| Stage | Typical time | Where the figure comes from |
|---|---|---|
| Thin brushed acrylic layer | Touch dry in about 2–3 minutes; about 8–10 minutes between coats | Modelskibet's guide to Vallejo Model Color |
| Airbrushed paint | Very fine coats dry within seconds | Vallejo FAQ (Model Air) |
| Spray primer | 10–15 minutes before painting in good weather; a few hours or overnight to dry completely | The Army Painter (older printed guide and current priming guide) |
| One-coat speed paint | No fixed official time; one reviewer measured about 20 minutes at around 60 °F (roughly 15–16 °C) and 50% humidity | Spikey Bits review of Speedpaint 2.0 |
| Dip-style shading varnish | 24–48 hours to harden; at least 48 hours before a matt varnish | The Army Painter Quickshade instructions |
| Varnish | Thin airbrushed coats 10–15 minutes; brushed gloss varnish 4 hours between coats (label advice) | Vallejo FAQ |
| Full hardness of the paint film | 48 hours or more (Vallejo); a few days for thin films (Golden) | Vallejo FAQ; Golden technical notes |
Washes and shades
Washes are thin, but they pool in recesses, so the pooled areas stay wet much longer than the raised surfaces. Wait until the recesses are no longer shiny or wet-looking before you highlight over them; if you rush, your brush can drag the wash back out of the crevices.
One-coat speed paints
Speed paints are designed to flow and settle in a single generous coat, and The Army Painter advises working in sections because they can dry quicker than you expect. If you want to add normal acrylic layers or highlights on top, the company recommends sealing the speed paint with a varnish first.
What slows drying down
- Thick paint. A heavy coat can feel dry on top while still wet underneath. This is one reason to thin your paints and build colour in several layers.
- Cold rooms. Golden says that below 9 °C acrylic polymers may not form a proper film at all, which can lead to cracking, poor adhesion or a powdery finish.
- Damp air. Relative humidity above 75% slows evaporation noticeably (Golden). For spray primer, The Army Painter suggests 15–27 °C and 40–60% humidity as the ideal range.
- Retarders and extra medium. Retarder deliberately slows drying. Vallejo recommends using no more than 5% of the paint volume. Vallejo's thinner and plain water also slow drying a little.
A wet palette keeps paint workable on the palette for longer, but it does not change how quickly the paint dries once it is on the model.
How to speed drying up safely
- Use a hair dryer on a low heat setting, held at a distance. Vallejo suggests exactly this, so the airflow does not disturb the wet paint. Golden warns that too much heat can make acrylic bubble, so keep it gentle.
- Keep the room warm and the air moving gently. A steady, moderate airflow helps; a strong draught pointed straight at wet paint can cause cracking or wrinkling (Golden).
- Paint thinner coats. Two thin layers usually dry faster, and look better, than one thick one.
- Rotate between models. Batch painting lets one model dry while you work on the next, so you are never waiting.
How to tell when paint is dry enough
- The surface has lost its wet sheen and looks even.
- It no longer feels cool when you hold the model close to your cheek or the back of your hand (cool usually means water is still evaporating).
- A light touch on an area that will be hidden, such as under the base rim, leaves no mark or tackiness.
- For varnish, primer or dips, wait the full time on the label rather than trusting touch alone.

Frequently asked questions
How long should I wait between layers of miniature paint?
For thin brushed acrylic layers in a warm, dry room, around ten minutes is usually enough; Modelskibet's Vallejo guide gives 8–10 minutes between coats. Wait longer for thick coats, washes or a cold, damp room.
Why is my paint still tacky after an hour?
The usual causes are thick coats, high humidity, a cold room or too much retarder or medium. Move the model somewhere warmer with gentle airflow and give it more time; Golden notes that cold below 9 °C can stop acrylic forming a proper film.
How long before I can varnish a painted miniature?
Let normal acrylic paint dry thoroughly first, ideally for a day or more, because Vallejo says full adhesion can take 48 hours or more. If you used a dip-style shading varnish, The Army Painter says to wait at least 48 hours before its matt varnish.
Can I use a hair dryer to dry miniature paint?
Yes, on a low heat setting and held at a distance, as Vallejo recommends. Too much heat can make acrylic bubble, so avoid hot air close to the model.
How long does spray primer take to dry before painting?
The Army Painter's older guide says models can be ready to paint after 10–15 minutes in good weather, while its current priming guide recommends a few hours or overnight for complete drying, especially in cold or humid conditions.
