The most important step of any miniature paint job is priming. A primer or undercoat is a preparatory coating placed on the surface of a miniature before painting. The use a primer ensures that paint adheres to the surface and helps paint durability. This is especially important if you’re using the miniature or model for gaming purposes, such as those for tabletop wargames like Warhammer 40k or Age of Sigmar, and board games. Of course, the best primer for the job depends on the surface material you’re painting. In my experience, I found Vallejo Surface Primer to be one of the best do-it-all primers.

In this article, I review the use of Vallejo Surface Primer for painting miniatures and models.

What is Vallejo Surface Primer?

Vallejo is a company brand that makes products for hobbyists. The company was established in 1965 in New Jersey, USA. Back in those days, they made water based acrylic colors for film cartoons (e.g., Disney animations and other moving picture drawings). Later, the company moved to Spain, since many cartoon studios were in Europe. There was something special about the formulae Vallejo used in their acrylic paints. Vallejo is still special, in fact.

To this day, Vallejo is one of the many respected producers of paints and products for professional artists, hobbyists, and other creatives.

The Vallejo Surface Primers are a range of basic colors that many painters use for preparing their models and miniatures before the painting process.

Surface Primer is available in a range of basic shades most frequently employed to prepare the surface of the model or miniature before starting the painting process.

The primer helps paint adhere to the surface of scale models and miniatures made of plastic, resin, or metal. The primer also works well as a surface undercoat for PVC and wood. Additionally, I’ve used Vallejo Surface Primer to great effect for preparing cardboard terrain wargaming terrain pieces.

Vallejo Surface Primer also acts as a thin adhesive skin that seals the microscopic imperfections on the surface of materials that helps make advanced paint color blending possible on finely detailed sculpts. I’ve even used it as primer before oil painting miniatures.

3 Reasons why Vallejo Surface Primer is superior to spray can primers

  1. Environmentally-friendly
  2. Works well in high humidity, more extreme temperatures
  3. Cost-effective

1. Environmentally-friendly

Vallejo Surface Primers are a water-based polymer (polyurethane) that doesn’t require harmful propellants or volatile solvents required for aerosol spray can primers. Some spray can primers also rattle because they have an agitator inside the can that helps mix the paint/primer with the solvent.

In general, a spray can primer is less efficient and wasteful because the system requires a lot of support material to “spray atomize” the liquid primer inside the can.

On the other hand, with a Vallejo Surface Primer, all you need is a brush or airbrush to apply the primer onto your working surface.


2. Works well in high humidity, more extreme temperatures

One of the risks of using a spray can primer is that they tend to become unreliable as humidity rises and temperatures become too cold or hot. This is due partly to the fact that spray can primers use volatile solvents (e.g., fluids with low evaporation temperature) that are very sensitive to temperature.

Heat or cold will drastically change the baseline amount of pressure that is inside the spray can, which can make spraying a primer unreliable and potentially disastrous.

Humidity or water-content in the air will affect how primer from a spray can will work on the surface of your model. Without getting into the granular details of how aerosolized primer works, I will say that high humidity is very bad for a smooth primer application through a spray can.

Some spray can primers are more sensitive to poor environmental conditions than others. Citadel and Army Painter spray can primers, particularly white colored primers are prone to clumping and texturizing the surface. Image source: Reddit

The water in the air will condense around the primer particles (as the primer atomizes) and make the primer “clump” or congeal, and even dry, before it hits your model’s surface. This creates that bumpy, undesirable texture on a bad primer job.

You can avoid these issues by using a liquid polyurethane-based primer, like Vallejo Surface Primers.


3. Cost-effective

Vallejo surface primers are a great value that will save you a lot of money.

The use of a liquid surface primer is more cost-effective than spray can primers. For the cost of a single rattle can spray primer from Citadel (Games Workshop) or Army Painter, you could buy two 60ml or one 200ml bottle of Vallejo Surface Primer.

A 200ml bottle of Vallejo Surface Primer has more than 300% more primer solution in it than a single 9.9oz can of Citadel spray primer (which is mostly solvent and propellant than primer anyway).

This ultimately means more model priming from your hard earned hobby budget when you use a Vallejo Surface Primer, as compared with spray can primers.


Best primer color for painting miniatures?

For speed painting or tabletop quality paint jobs, black or very dark colored primers work best. This is because when you want to paint fast, getting the shadows painted dark is often the slowest process when you’re painting with regular acrylic model paint. If you start with black or dark primer, you’re starting from a point where you don’t need to worry so much about shading your recessed areas on a model.

For display or normal painting of miniatures, I suggest using a grey (my favorite) or white colored primer. The reason you would want to start with a lighter colored primer is because it will help you see the details on your model better. Highlights and shadows will naturally fall on your primed sculpt as you look at it under good lighting conditions.

If you’re looking to paint with transparent inks or washes, you could use both a black and white primer applied with a zenithal highlight technique. In this approach, you undercoat with a black primer, followed by an overhead spray of white primer from above (from the zenith). This pulls out details as though a bright light source is shining down from above. This creates a gradient of primer that naturally shows you where highlights might fall on your model.


Best way to apply Vallejo Surface Primer?

You can apply Vallejo Surface Primer with a regular brush or an airbrush. There are advantages and disadvantages of brushing and airbrushing with a surface primer, as there are for regular acrylic model paints.

Key tip: For best results, shake your primer bottle vigorously to mix the primer solution. To speed things up, use an small vortex mixer.

Brush versus airbrush

As an example of using a brush and airbrush to apply Vallejo Surface Primer, I 3D printed a “White Walker” bust (a character from the Game of Thrones TV show).

Brush application with Vallejo Surface Primer

How well does Vallejo Surface Primer work with a brush?

Vallejo Surface Primers work great when applied to models with regular brush.

Vallejo primer looks like crude oil

You don’t need an expensive brush for applying a surface primer. Vallejo surface primer flows nicely and mixes well with water if you need to thin it. I tend to use a drop of water to thin my primers so they go on smoothly.

Although I show my example in this review with German Panzer Grey, all the Vallejo Surface Primer colors work the same. They have a good consistency and surface tension, which makes them easy to apply.

The primer is easy to apply with a brush. It goes on thin and covers well.

With a brush, you can apply fairly heavy coats. Just don’t let the primer pool up in the recesses as this will block out details, but also make the primer dry too slowly. Soak up any excess primer with a clean brush, if you need to.

Smooth and even application with a brush preserves all the fine details of the model’s face

The nice thing about Vallejo Surface Primer is that it will dry into a stretched out, durable layer in an even homogenized surface. So, even if you use a thick coat of the primer, more than likely, it will still create a smooth surface, pulling itself thin as it dries.

A wet primer appears darker and shinier than when it dries

For the highly-detailed 3D prints, this is great because the Vallejo Surface Primer will allow you to use liberal applications of the primer without obscuring details. For plastic, metal, or resin kits, you will enjoy how easy it is to smoothly apply the primer with a brush.


Airbrushing Vallejo Surface Primer

How well does Vallejo Surface Primer work through an airbrush?

The best way, I think, of applying any surface primer is with a spray technique. This means that if you’re using Vallejo Surface Primer, you’ll want to airbrush it onto your model for the best results. This is because the atomized primer spray will lightly, but effectively coat your model in a smooth layer.

A few drops of primer in my Badger airbrush and it’s ready to go.

Here I used a stress test of the Vallejo Surface Primer using my Sotar 20/20 airbrush (see airbrush reviews here). The Sotar 20/20 I use has a 0.2mm nozzle, which is fairly small for airbrushing base coat layers, which are usually thick paints.

This is one of my favorite airbrushes for painting details on miniatures

It is recommended to use an airbrush with at least a standard size 0.3mm nozzle or larger to avoid clogging.

To thin the primer properly for airbrushing, I tend to use water or a few drops of Vallejo Airbrush Thinner. The thinner is essentially a flow-improver additive that helps thin paint or primer while maintaining its binding properties so it sticks to surfaces. Sometimes with too much water, diluted paint or primer will become too running and become hard to control (e.g., leading to splattering or dripping).

Vallejo recommends using an air compressor setting of around 15-20 PSI. This is a pretty accurate pressure in my experience too working with Vallejo Surface Primer, even in my Sotar 20/20 airbrush. You could go to a slightly air pressure if you’re using a larger nozzle like the 0.3-0.5mm nozzles on Badger Patriot 105 airbrushes, for example.

In this airbrush priming test, I sprayed a small region of the chest/sternum of the bust. As you can see from a quick airbrush burst, the primer quickly adhered to the model in a thin layer. The application was easy and fast.

A closer looks shows how all the details are still visible. As compared with the brush application of primer, airbrushing the surface primer was not only faster, but created a much thinner surface. A notable benefit of airbrushing primer is that you don’t waste a lot of the primer on the bristles of your brush. Most of it leaves the airbrush as you apply it to a model.


Is airbrushing Vallejo Surface Primer safe?

Any foreign particles entering your lungs could be a potential hazard. Things like asthma, allergies, and other chronic respiratory diseases may be triggered by inhaling the airbrush spray of any primer.

Take precautions and use a respirator or a spray booth when you’re spraying surface primer through your airbrush.

Note that Vallejo Surface Primers are not flammable, and do not contain solvents. Vallejo has additional documentation about the safety of their surface primer products, e.g., safety document sheet (SDS), which you can check out here.


How long should I wait for primer to dry?

You can tell when Vallejo Surface Primer is dry by looking at the color and reflection on the model. As primer dries, the color lightens and the reflections decrease (unless you’re spraying the black gloss surface primer).

From my experience, at room temperature (~25C or 70-75F) and normal humidity, it only takes about 5-10 minutes for an airbrushed primer application to dry. If I used a paint brush to apply the primer, it may take a bit longer, up to 20-30 minutes for the primer to dry. This is because a brush on application of surface primer will usually be thicker than airbrushing the primer.

Notice in the photo above how the surface primer on the head (which had the brush on application) appears to be still wet and damp, as compared with the chest and trunk section (which had the airbrush application).

For a truly durable surface for painting, you will want to wait at least a few hours if not overnight for your surface primer to dry.

After an overnight wait, you can see how the surface primer has dried into a thin even looking surface. All the details in the model are still visible, even the 3D print lines. To cover those 3D printing artifacts, a few more layers of the surface primer can help, or you can look into use gap fillers.

Pro tip: to speed up primer drying, you can use a hair dryer set to the its lowest heat setting. See other reasons why you may want a hair dryer for painting miniatures here.


What is better for priming: airbrush or regular brush?

An airbrush is better for applying a surface primer because it is faster, wastes less paint, and applies a smoother and thinner primer coat (which preserves model surface details).

If you don’t have an airbrush or prefer to avoid the maintenance (and potential clogging) of your airbrush when priming, a regular brush will work great with Vallejo Surface Primer (see results above). Just remember that you can thin your primer with water or thinner additives to help it flow off your brush. Make sure to avoid letting primer pool in recesses.

Pros and Cons of Airbrush Priming

Pros

  • Airbrushing is faster
  • Wastes less primer
  • Spraying a primer preserves model surface details

Cons

  • Requires airbrush equipment and accessories
  • More cleaning and tool maintenance
  • Potential hazard with aerosolized primer

Best alternative surface primers to Vallejo Surface Primer?

There are 2 other surface primers I recommend if you don’t want to use Vallejo Surface Primer or it is hard to find:

  1. AK Interactive Primer
  2. Badger STYNYLREZ

Both AK Interactive Primer and Badger STYNYLREZ are worthy competitors of Vallejo Surface Primer. You can use the same application techniques with any of these surface primers, either using a regular brush or airbrush. They also come in a variety of colors, though I do recommend only using one of the neutral colors, black, gray, or white (as you’ll be painting over these primers anyway).

Conclusion

Vallejo Surface Primer is an amazing product for hobbyists who paint miniatures and models. The primer is easy to use, accessible, cost-effective, and safe with its intended use. You can apply the primer effectively with an airbrush or regular brush, and will get a great surface that prepares your model for model acrylic or even oil paint.

To thin Vallejo Surface Primer, you can use water or flow improver additives, such as the Vallejo Thinner. When you airbrush keeping your air pressure low (around 15-20 PSI) will help you keep control over the spray pattern.

I’ve used Vallejo Surface Primer for years for painting miniatures. I’ve gone through several 200ml bottles of the primer to paint the hundreds or even thousands of models I’ve worked on for commission and personal products. If I had used a spray can primers, I would have spent a lot of money unnecessarily.

In fact, I estimate that the money I saved using the surface primer instead of rattle can primers has easily paid off my airbrush equipment investment. You can see my recommended airbrushes for painting miniatures here or the full airbrush guide here.

Overall, I highly-recommend the use of Vallejo Surface Primer to anyone who paints miniatures or works with models large and small.

Happy painting (and priming)!

  1. Thanks for reviewing this, I can’t tell you how many models I’ve left unpainted because I couldn’t find a decently thin primer. I just ordered a bottle along some other supplies I’m going to need in the near future. By the way, you should add Micro-Mark listings for any painting or modelling supplies you review. I get my supplies almost exclusively from them, and their prices are pretty good – a 200ml bottle of Vallejo primer is $15 from Micro-Mark, vs. $20 from Amazon.

      1. Most of the time they do, but it’s not very much, and there is the occasional free shipping promo (usually on large orders) or other discount available.
