Picking the right primer can make or break your painting experience on your miniatures. With so many options to choose from, it can be hard to choose which is the best primer for miniatures.

Primers need to be picked according to the surface material of your miniature as there are other primers that work best only on specific surfaces like plastic or metals.

In general, primers are used as a preparatory coat over an unpainted surface like plastic or metal. But in the case of miniature primers, brush-on or spray primers that make smooth surfaces are the preferred primers to make painting smooth when held by your miniature holder.

In this article, we will cover the best primer for miniatures and models and talk about the most important factors that matter when shopping for a primer.

Why Should You Use Primers for Miniatures?

There are two primary reasons why primers are crucial when painting miniatures or models.

The first reason why miniature primers are used is that it gives an undertone on the miniature before you apply the actual colors. The second reason is that the primer bonds on the surface of your miniature and avoid compromising the color quality of your second coating.

But apart from those two, there are other reasons why primers are used on miniatures or models, which we’ll cover briefly in this article.

Primers for Miniature Helps Acrylic Paint to Stick to the Surface

Acrylic paints do not stick well to metals, plastic, or resin very well. However, primers do adhere to these surfaces really well and also provide a layer for your colored paint to cling to. Without primers, you will see the paint flaking off sooner or later.

Depending on the number of layers of primer you put will be how the surface will look like. For example, if you put too much primer on the miniatures, you will have an extremely smooth, plastic-like surface. Unfortunately, too much primer could cause the paint to not stick properly.

On the other hand, less primer on the miniature will give you better-defined detail that will promote your colored painting’s details.

When it comes to choosing the right primer for you, you should base it off according to the colors you will be using. If you are going to use darker colors, then know that you will need a darker primer to get the right darkness. On the other hand, if you are going to use light colors, then a light primer will fit best.

Essentially, you can choose primers that range from black to gray to white, depending on your needs. Among the shades of primers, gray is the most commonly used while the white primer is great for vibrant colors.

Bottom line is that it’s important to pair your primer’s color with the colors you will be working on because choosing dark primers will give you results that will look a bit dull on your miniatures or models.

Primers for Miniatures Help Prevent Scratches and Minor Flaws

Another primary use of primers is how it creates an even surface in preparation for the second coating colors you will be adding. The smooth surface is achieved because the primer fills in minor cracks and scratches on the miniature or models.

When you are working on miniature vehicles and aircraft, a smooth surface is very important as an uneven surface could damage the overall output. By using the right primer, you will achieve a really smooth surface that will make vehicles look even better.

Apart from vehicles, most miniatures have fine details and corner surfaces that require a detailed application. Using the right primer will coat these delicate areas perfectly so you can apply the details as accurately as they can be.

Primer for Miniatures Offer a Color Base

Primers have their own color, which makes it all the more crucial to choose accordingly. Depending on the color of the primer and the color you will be applying on the primer will be how well the item will turn out.

Even though primers come in a variety of colors, the most popular colors range from white, gray, and black. However, it doesn’t necessarily mean that you have to go with either white, gray, or black, as well, since it depends on the person’s painting process.

For example, some people use white more often while others avoid using it at all. Other people also often use gray rather than either white or black because it is the middle color to use. Ultimately, it boils down to how you want your final color to look like.

Primer offers More Precise Detail

The number of primers you add to your miniature models also matters. Depending on how much primer you add will make or break your painting details.

You see, if you add too much primer, it tends to cover up the details of fine lines and round edges of the miniatures. That is why knowing how much primer you add is very important if you don’t want to ruin the details later on.

However, not everyone knows how much primer to add. So, how do you know when enough is enough?

To know when you have added enough primer, your miniature should have a shiny surface once your miniature item has been cleaned. If you are going to use spray primers, make sure you apply this in a well-ventilated room or outside where there is plenty of natural light.

In most cases, the primer should provide a matte look– not glossy. When using miniature paints, place the miniature about a foot away from you and use short bursts of sprays, and apply it evenly on all sides of the miniature or model.

Once you have applied enough on all sides of the miniature, allow it to dry and it should have a completely matte look.

Because of the smell, it is highly advised that you work in a well-ventilated area to ensure that the smell won’t stay in one area or stick on surfaces.

The overall viscosity of the Liquitex Neutral Gray Gesso is very flexible and it is also distinguishable as a thin primer, allowing you to preserve fine painting details on miniature models. However, when using brush in layers, it is still highly advised to be really careful when brush painting miniatures, especially when it comes to preserving details on a miniature model.

Note that because this is still a spray can, painting in a well-ventilated room or places is still highly advised. To avoid overcoating the model, keep some distance away from the model. This also ensures you will not lose any details on your miniatures.

Things to Consider when Looking for the Best Primer for Miniature

Choosing the right primer doesn’t just revolve around picking the right texture or shade. You see, there are other factors that could make or break your purchase. In this section, we will cover the things you should worry about besides color or shade.

Brush or Spray

When shopping for primers for miniature models, the first thing you need to consider is to check whether or not you need rush or spray. Both these methods are done differently but focus more on control.

If you need to get your primers on your models fast, then spraying should get what you need fast. On the other hand, if you need to add primers accurately in specific parts of your model, then the brush method should give you more control. Unfortunately, this is time-consuming compared to sprayable primers.


Another thing you should also consider when looking for primers for miniatures and models is the color. Picking the right base color for your miniatures will help make the output look great.

Because the base color could greatly affect the outcome of the miniature, knowing which color to choose is crucial. For example, choosing a prink primer for a zombie army won’t turn out really great.


The size of the miniature model is also something you need to consider when choosing a primer. Note that spraying or brushing makes a difference, depending on the thickness of the primer.


When working on a large number of armies or smaller miniature models, spray primers normally work best. Brush primers may be ideal for larger models but it still doesn’t mean miniature models don’t benefit from it.

Regardless, picking the primer should depend on the type of material or miniature model you are painting. Remember, metal miniatures will require primers that work best on metal materials as opposed to plastic or wood miniatures.


Mind the type of primer you will use on miniatures, especially if kids are likely to get in contact with the miniature model you will be painting. Even if kids are old enough not to put toys in their mouths, you still have to be careful.

Figures that are colorful enough can be too attractive to kids, and it’s better to stay safe than sorry. For this case, it is important to use primers and colors that are non-toxic.
