Would you like to paint plastic or metal miniatures and are you looking for the ideal primer? Each primer works differently depending on the product and the surface you are using it on. All primers act the same on the surface and are used as a first coat to prepare the surface of unpainted plastic, resin or metal. Primers are also applied to prevent the paint to be applied later from being absorbed by the material being worked on. Another benefit of primers is that they create a smooth work surface, covering and filling in imperfections.

What is a primer?
Primers are used as a base before painting begins. You need a good primer so that later applications of the products do not cause any problems. A primer is a product used to coat an unpainted surface. With the primer you prepare the surface for the application of the necessary modeling paint.
Regardless of the type of material you're working on, whether it's resin, plastic, or metal, you can create a universal surface to work on by applying a primer. If you love wearing cosmetics and makeup, you already have a good idea of the importance of foundation. When applying makeup, a foundation is applied to the skin to prevent the makeup from being absorbed into the skin. Primer also ensures you have a smooth surface to work with.
By applying a primer you create a surface where you have more control over the result, whether you are working with makeup, an art medium or acrylic paint. If you want to paint miniatures, you need a primer that will give you a solid base.
The best primer for metal and plastic miniatures
When working with 28-35mm scale plastic miniatures, we recommend a spray primer. However, when working with larger miniatures, you can use any primer. The main purpose of a primer is to ensure you have a thin, even surface ready for painting.
When applying your foundation, you want to make sure you aren't covering up any detail. To do this, make sure your first primer is very thin. Choose a primer that is not too thick so that you can easily apply thin layers. Therefore, a spray primer is an ideal solution for smaller miniatures, as it is easy to apply thin layers to the model.
Spray primers are the best choice for miniatures, and while there's nothing wrong with a brush primer, you can't use them to apply as thin layers as you can with a spray. We've selected some of the best primers for your miniature project, some of which can be applied by spraying and others by brushing.

Why you should use primer to paint miniatures
There are two main purposes for the primer:
- The primer forms a base layer onto which enamel paint can be applied.
- Primer ensures that the paint adheres to the miniature.
In addition to these purposes, the primer also fills in small scratches and holes to create a smooth, even surface. If the surface is not smooth, the paint may not stick to it. Primers also offer a color cast, although their thicker consistency means it's easy to lose detail on your miniature's surface.
Primer allows acrylic paint to adhere
Even if you have thoroughly cleaned your miniature, whether plastic, resin or metal, you will find that acrylic paint does not adhere well to it. By using primer you can create a surface that will stick to paint. too, especially those like a metal surface. If you don't use a primer, your acrylic paint can easily chip or peel off the surface.
Primer fills in minor blemishes and scratches
The primer plays an important role in filling in blemishes and small scratches on the surface of your miniature to ensure you have an even surface to apply your paint to. This is a great feature of the primer, especially since most miniatures will get dented or scratched through wear and use. The primer is even more beneficial for filling in blemishes and scratches when used in other applications such as. B. automotive parts is used.
The miniatures have fine details that are present thanks to small marks on the surface of the material. Higher quality miniatures tend to have finer detail and finer textures. Using a quality primer allows you to apply thin coats to the miniature's surface without affecting the finer details in any way.
Primers add a color cast
Although the primer is intended to be applied under paint, the substance is not light. The primer is an opaque color that you can use to your advantage or in battle. Grey, black or white are the most common colors of primer, but you will be able to find primer in almost any color imaginable. The white base is the choice for most hobbyists, while some use gray as a compromise if white isn't available.
A lot is up to you when it comes to choosing which primer color to use. We suggest that you consider the paint colors you will be using and whether they will be primarily dark or light colors. If you choose not to use a light base coat, the lighter areas in your piece can end up looking rather monotonous. A good option is to use a white primer as it works well with bolder shades of paint.
Use less primer for sharper details
Don't apply the primer too thickly as this will spoil the detail of the miniature. As mentioned, high-end miniatures tend to have finer detail and you don't want to damage such intricate parts by applying too thick a primer.
How can you make sure you've applied enough primer? A cleaned miniature, whether it's plastic, resin, or metal, will usually have a shiny finish. Apply your spray primer to an area with good lighting so you can see the reflected light anywhere on the miniature that still needs to be primed.
You should use a flat or matte primer as it is non-reflective. Apply the primer by spraying in short bursts while holding the miniature about a foot from the spray can (this is about a third of a meter). You only need to apply enough primer to cover the miniature's reflectivity.
The way you prime your miniatures can significantly affect the results. The main goal is to apply the primer as evenly, consistently and thinly as possible without affecting the fine details of the miniature. You want to create a smooth surface that the paint can easily adhere to.
You will find that there are many projects that you cannot use a spray primer on as you always need a well ventilated area to spray. There may be times when you need to use a brush to apply your foundation. This may be because you are in a small room, such as a bedroom. B. in an apartment or at a meeting, or that the weather is damp or too cold to spray outside.
Some hobbyists prefer the brush approach, but you will need more patience and skill if you choose this application option. If you apply the primer with a brush, you will get thicker layers. We recommend that you take your time with this application method and use a flat head brush.
If you choose to apply the primer with an airbrush, you can effortlessly apply thin, even coats and avoid air bubbles. psi.
You may need to thin the primer, especially if you chose a brush-on primer that is thicker. You are looking for a milk-like foundation consistency. To thin the primer, you can use 1 part airbrush thinner or water to about 3 parts primer.
Another easy application for the primer is through spray cans. You can buy generic primers, industrial primers, or special miniature primers. General industrial primers are very affordable and can be bought in bulk.
You won't apply as thinly when using aerosols as with airbrushing, where some cheaper aerosol options can result in a grainy finish. You can sand industrial primers after drying, which is not possible. to do with specific primers for thumbnails. This sanding allows you to create a smooth surface before you start applying the paint.
These disadvantages mean that you should only use an aerosol primer for miniatures and large parts that don't have finer, more intricate detail, as this form of spray application covers larger areas at a cheaper price.
Spray primer doesn't produce a fine spray like an airbrush, so to avoid lots of waste or primer we recommend spraying multiple pieces at a time.
Top tips for printing thumbnails
There are a number of tips and tricks to help you prepare miniature surfaces for painting. However, before you can apply the primer, you need to make sure your miniature's surface is completely clean and dry. You may also need help choosing the best shade of primer for your project.
Substrate preparation for priming
The main purpose of the primer is to adhere well to the miniature, which means it is important that you have cleaned your miniature sufficiently before you start applying the primer.
Miniatures are made with molds, filling the mold with liquid plastic, resin, or metal. They are then allowed to harden by cooling. After curing, the miniature must be demolded. So that this is possible without any problems, the mold is first coated with a lubricant to facilitate demoulding.
Mold release is similar to a non-stick spray you would use on a pan and ensures the miniature pops out of the mold with ease. However, this means that your miniature will be coated in a thin, invisible layer of lubricant. This lubricant negatively affects the process of applying glue, primer and paint.
Therefore, it is important to start any miniature project with a thorough cleaning of the figures. You can clean them with soap and water. It is very important to start this cleaning process.
What is the best color choice for a primer?
We recommend sticking with neutral colors like black, gray, or white. You can buy a variety of colors, but those that differ from the basic colors can be quite expensive. Since you'll be painting over the primer anyway with your chosen paint colors, most layers of the primer won't even show through.
The reference colors for the primers are black, white or gray, the choice depends on your eyes. Are you one of those who prefer lights or shadows? Do you want to make something darker or lighter while painting? This is a very personal preference as the primer color you choose will have minimal impact on the final color of the paintwork.
Prepare your thumbnail
- If you have decided to use an airbrush or spray can, be careful not to get too close to the miniature when using the equipment.If it's too close, it can result in "spider webs" or spatter caused by the spray pushing the primer onto the miniature's surface. Start spraying away from the miniature, using short, quick bursts at least 6 inches away.
- Always start preparing your miniature before you start applying the primer.. Quickly clean the miniature with mild soap and a toothbrush. Because most miniatures are made in molds, they are often coated with a release agent. If the thumbnail is still coatedrelease agent, primer and paint will not stick to your surface.
- When using a rattle spray can, the weather can play a role.If the weather is extreme, very humid or freezing cold, it can affect your results.
- Never apply thick coats of primer to a miniature; Always use thin layers.This is to ensure that the fine details of the piece are not compromised in any way.
- Allow each coat to dry before applying a new coat.It may take 30 minutes to an hour to dry sufficiently.
