I remember the first time I looked at a can of Citadel Chaos Black. I was maybe 15, drowning in excitement about a new Warhammer army, and completely clueless. The can said ‘spray paint.’ The guy at the hobby shop, bless his heart, just nodded when I asked if it would work. He didn’t say if all Citadel spray paints are primers, and I didn’t ask. Turns out, the answer is a resounding ‘not necessarily,’ and that’s a lesson I learned the hard way.
Wasting perfectly good primer on a project that just wouldn’t hold paint later is a special kind of pain. You think you’re set, you’ve got the perfect base coat, and then… nothing. It peels, it flakes, it slides off like it’s on ice. So, to clear up the confusion once and for all: are all Citadel spray paints primers? Let’s get into it.
Primer vs. Paint: What’s Actually Going on?
Alright, let’s cut to the chase. The idea that all Citadel spray paints are primers is a myth, a bit of gamer folklore that needs busting.
Citadel makes a wide range of spray paints, and while many of them do function excellently as primers, not all of them are designed with that primary purpose in mind. Think of it like this: a hammer can be used to pound in a nail, but it’s also a perfectly capable rock-smashing tool. Some spray paints are built specifically for that ‘primer’ job – adhesion, a matte surface for paint to grip onto, and durability. Others are more about laying down a specific colour coat, and while they might stick, they aren’t optimized for the grunt work of priming.
Citadel’s own range is a good example. They have dedicated ‘Primer’ sprays – think Chaos Black, White Scar, Macragge Blue, and so on. These are formulated to provide that important grip for your subsequent layers of paint. They tend to have a finer atomization, a less ‘plasticky’ feel when dry, and are generally more forgiving if you miss a spot or two.
Then you have their regular colour sprays, like Leadbelcher or Retributor Armour. These are fantastic for base coating an entire model quickly, and yes, they will often provide decent adhesion.
But if you’re looking for the absolute best foundation for your paint job, especially if you’re going to be doing a lot of layering, washes, and drybrushing, you’re usually better off with one of their dedicated primers.
The chemical makeup is different. Primers often contain solvents that slightly etch into the plastic or metal surface, creating microscopic tooth for paint to cling to. They also typically have a higher concentration of pigments that create a dense, opaque layer. Regular colour sprays might have different binders and pigments that are optimized for covering power or a specific finish (like metallic sheen), not necessarily for long-term paint adhesion on its own. It’s the difference between a foundation garment and a stylish dress – both are clothing, but they serve different core functions.
I learned this the hard way with some bright green Necron models. I used a green Citadel spray paint, thinking, ‘Why buy primer AND paint?’ Big mistake. The paint looked great initially, nice and even. But when I started applying washes, they just beaded up. Then, when I tried to gently clean a mistake with a damp brush, huge chunks of paint just peeled off. It felt like I was painting on glass. That was a harsh lesson in why a dedicated primer is usually worth the extra couple of bucks. The time spent stripping and re-priming was way more expensive in terms of frustration and lost hobby time.
The Science Behind the Stick: How Primers Work
So, what makes a primer actually ‘prime’? It’s all about surface chemistry and physics, really. When you spray a primer, you’re laying down a layer of material designed to bond with the substrate (your plastic miniature, metal model, or whatever you’re painting) and also provide an ideal surface for your subsequent paint layers. Dedicated primers typically have a formulation that includes solvents capable of slightly ‘melting’ or etching the surface of the material they’re applied to. This creates a microscopic ‘tooth’ – think of it like sandpapering a surface before painting, but on a nano-level. This tiny roughness gives the paint something to physically grip onto.
Beyond the etching, primers are formulated with specific binders and pigments. The binders are the glue that holds everything together and allows it to adhere to the surface. Different plastics and metals require different binders for optimal adhesion. Citadel’s primers, being designed for the hobby market, are generally tested for good compatibility with the plastics used in most miniature wargaming kits. The pigments in primers are often chosen not just for colour, but for their opacity and their ability to create a matte, non-porous surface. A matte surface is far superior for paint adhesion than a glossy one, which is why many colour sprays, if they aren’t primers, can be a bit more slippery. (See Also: Can Craft Foam Be Spray Painted )
The other key factor is atomization and propellant. Good primers spray a very fine mist. This means the paint particles are small and evenly distributed, settling onto the surface without creating a thick, plastic-y layer that can obscure detail or feel brittle. The propellant in the can is also engineered to work with the solvents and binders in the paint to make sure a smooth, even application and quick, effective drying. Cheaper or less specialized spray paints might have coarser particles or different solvent/binder ratios that just don’t create that same tenacious bond.
It’s also worth noting that some materials are notoriously difficult to paint over without a primer. Certain types of plastic, like the very smooth, almost waxy ones found on some older model kits or certain toys, can be almost impossible to get paint to stick to directly. Primers are the magic bullet for these surfaces. They create that key bridge between the slick material and your chosen paints. So, while a colour spray might cover well, it might not be adhering well. That’s the fundamental difference that makes a dedicated primer so invaluable for long-term durability.
Citadel Colour Sprays: Good Enough?
This is where the grey area really comes into play, and where a lot of people get tripped up. Can you use Citadel colour spray paints like Leadbelcher, Mephiston Red, or Death Guard Green as primers? In many cases, yes, they will function as a primer. They will lay down a colour, and they will adhere to the model reasonably well. For quick projects, or if you’re not planning on heavy weathering or extensive handling, they can absolutely get the job done. I’ve certainly done it myself when I was in a rush or just wanted a quick, uniform base coat. They cover well and can save a ton of time compared to brush-on base coats.
However, here’s the contrarian opinion: I think relying solely on Citadel colour sprays as your primer is often a false economy, and here’s why. While they might stick initially, their long-term adhesion and durability can be questionable, especially compared to their dedicated primer range. I’ve had models painted with colour sprays start to show wear and tear faster than those done with proper primers. The paint might chip more easily around edges, or washes might not flow into recesses as smoothly because the surface isn’t as ‘grippy’ as a dedicated primer would make it. It’s like building a house on a slightly uneven foundation – it might stand, but it’s not as stable as it could be.
Furthermore, the finish of a colour spray is often different. Some of them have a slight sheen even when dry, which isn’t ideal for subsequent paint layers, especially if you’re planning on using heavy washes or glazes. Dedicated primers are almost always matte, providing that perfect ‘tooth’ for paint. You’re basically asking a paint designed to be a mid-coat or finish coat to do the heavy lifting of a primer, and it’s not always optimized for that. The solvents in a colour spray might be different, designed to bond with acrylics rather than etch into plastic. This can lead to a surface that feels a bit ‘slippery’ to the touch, even if it looks fine.
So, are they primers? Technically, they might provide a base layer that paint sticks to. But are they as good as dedicated primers? In my experience, usually not. If you’re on a tight budget or painting a practice model, go for it. But for your prized display pieces or armies that get handled a lot, investing in a dedicated Citadel primer is, in my blunt opinion, the smarter move for a paint job that lasts and looks its best. You’re saving yourself potential headaches down the line.
| Product Type | Primary Function | Primer Capability | Opinion/Verdict |
|---|---|---|---|
| Citadel Dedicated Primer (e.g., Chaos Black Primer) | Adhesion, surface prep for paint | Excellent | Best Choice: Formulated for maximum adhesion and durability. Worth the extra cost for serious projects. |
| Citadel Colour Spray (e.g., Leadbelcher) | Laying down a base colour coat | Good (functional) | Situational Use: Can work as a primer for quick jobs or less demanding projects, but not as durable or grippy as dedicated primers. |
| Other Generic Spray Paints (non-hobby specific) | General surface coating | Variable/Poor | Risky: Adhesion can be very poor on plastics. May obscure detail. Use with extreme caution, if at all, for miniatures. |
Common Mistakes and How to Avoid Them
One of the biggest mistakes people make, and one I’ve definitely fallen for, is assuming that because a spray paint from a hobby company like Citadel is for miniatures, it must inherently function perfectly as a primer. As we’ve discussed, this isn’t always the case. The core error is conflating ‘paint designed for miniatures’ with ‘primer designed for miniatures.’ They are not interchangeable, even if they come in similar cans and from the same manufacturer.
Another common pitfall is the ‘too close, too far’ application. Spraying too close can lead to a ‘splatter’ effect, where the paint lands in blobs, obscuring detail and creating an uneven surface. Spraying too far away results in a dusty, ‘orange peel’ texture, where the paint particles dry before they hit the surface, leaving a rough, uneven coat that’s hard to paint over cleanly. The ideal distance is usually about 8-12 inches (20-30 cm), depending on the can and the paint. You want a fine, even mist to settle gently onto the model.
Environmental conditions are also huge. Spraying in high humidity or extreme cold can absolutely ruin a paint job. In high humidity, the moisture in the air can react with the paint solvents, causing the paint to dry cloudy, chalky, or with a weird, powdery texture. This is often called ‘blushing.’ In cold temperatures, the paint can freeze or become too viscous to spray properly, leading to poor adhesion and an uneven finish. Always aim for a temperate, dry environment. If you’re working outside, check the weather. If inside, make sure good ventilation but avoid drafts that can blow dust onto your wet paint.
Skipping the shake is another classic error. Those tiny ball bearings inside the can? They’re there to mix the pigments and binders thoroughly. (See Also: Can Aluminum Be Spray Painted )
If you don’t shake the can for a good 2-3 minutes, you’re going to get a can with propellant and some liquid, but the actual paint components won’t be mixed. This leads to inconsistent colour, poor coverage, and adhesion issues. I once had a can of primer that seemed to just spray clear carrier fluid for the first few seconds – that’s what happens when you don’t shake it enough.
A thorough shake is a must for good results. Finally, don’t be afraid to do a test spray. Before hitting your precious model, spray a piece of junk plastic, a spare sprue, or even a piece of cardboard.
This lets you check the spray pattern, the coverage, and how the paint feels when it dries.
Practical Application: When to Use What
Let’s break down when you should actually reach for a dedicated primer versus when a colour spray might suffice. For your main armies, especially those you plan to enter into tournaments, display, or just want to look their absolute best for years to come, always use a dedicated primer. This means Citadel’s Chaos Black, Corax White, Grey Seer, Macragge Blue, etc. These are formulated to give you the best possible foundation.
Think of it as preparing a canvas for an oil painting; you wouldn’t just slap paint onto raw cloth. You prepare it to receive the paint properly. I spent $180 on primer over three years for my main armies because I value that longevity and smooth finish.
It’s an investment in the final look and durability.
If you’re painting a batch of practice models, a quick terrain piece for a one-off game, or something you know is going to get heavily weathered or beaten up anyway, a Citadel colour spray can be a good option. For example, if I’m painting up a dozen goblin troopers for a casual game, and I know they’ll end up covered in mud and blood effects, I might use a Mephiston Red spray as my base. It covers quickly, gets them tabletop ready, and I’m not overly worried if a bit chips off during gameplay because they’ll be heavily battle-damaged anyway. It saves time and a bit of money, and the final result is still perfectly acceptable for that purpose. Sometimes speed and expediency are more important than absolute perfection.
What about those oddball plastics? If you’ve got something that feels unusually slick or waxy, like some older toy soldiers or certain types of resin prints, a dedicated hobby primer is even more important. You might even consider a specific hobby primer designed for tricky surfaces, or even a very light misting of a clear adhesion promoter before your primer. I had a set of resin miniatures from a smaller producer that were so smooth, normal spray paint just slid off.
After stripping them twice and trying different techniques, I finally got them to hold paint after using a specific model primer and letting it cure for a full 24 hours instead of the usual few. Patience and the right product are key here.
For anything metallic, like a tank or a knight, I still prefer priming black or grey first, then applying a metallic colour spray or brush-on metallics. This makes sure the base is solid before you go for that shiny finish. (See Also: Can Bug Spray Damage Car Paint )
When to Use Dedicated Primer vs. Colour Spray
Dedicated Primer: For your main armies, display pieces, models that will be handled frequently, and any difficult-to-adhere-to surfaces (like very smooth plastics or certain resins). This makes sure maximum paint adhesion, durability, and a proper matte surface for subsequent layers.
Colour Spray: For practice models, terrain, disposable units, or when you need to cover a large number of models very quickly and are prioritizing speed over ultimate durability. It’s a compromise that can save time and resources for less important projects.
People Also Ask
Do I Need to Prime Citadel Models?
Yes, it is highly recommended to prime Citadel models before painting. While some Citadel colour sprays can adhere reasonably well, a dedicated primer provides superior adhesion, a matte surface for paint to grip, and protects the plastic from the solvents in subsequent paints. Skipping primer can lead to paint chipping, peeling, or not adhering properly, especially with washes or heavy handling.
Can I Use Regular Spray Paint on Miniatures?
Using regular, hardware store spray paint on miniatures is generally not recommended. These paints often have coarser pigments, different chemical compositions, and can obscure fine details on models. Their adhesion on plastic can also be poor, and some solvents can even melt or warp the plastic. Hobby-specific spray paints, especially dedicated primers, are formulated for miniatures.
How Long Should Primer Dry Before Painting?
Most dedicated hobby primers are dry to the touch within 15-30 minutes. However, for optimal adhesion and to avoid disturbing the primer when applying subsequent layers (especially washes or heavy coats), it’s best to let it cure for at least 1-2 hours, and ideally 24 hours, especially in humid or cold conditions. This allows the solvents to fully evaporate and the binders to set.
What Is the Best Citadel Spray Primer Color?
The ‘best’ Citadel spray primer colour depends entirely on the colour scheme you intend to use. Chaos Black is excellent for creating a moody, dark base that makes colours pop when layered over it. Corax White or White Scar are ideal for vibrant, bright colour schemes where you want maximum colour saturation. Grey Seer is a good neutral middle ground, suitable for a wide range of colours and providing a balance between the two.
Can I Use a Citadel Color Spray Instead of Primer?
You can, but it’s not always ideal. Citadel colour sprays can function as a base coat and will adhere to the model. However, they are not formulated with the same aggressive adhesion properties or matte finish as their dedicated primers. For projects where durability and long-term paint adhesion are most important, a dedicated primer is a much safer and more effective choice.
Conclusion
So, to finally put the question to bed: are all Citadel spray paints primers? No, they are not. While many of their colour sprays can serve as a functional base coat, they don’t offer the same reliability and adhesion as their dedicated primer range. I’ve learned this lesson through experience, and honestly, the frustration of stripping paint and starting over is never worth saving a few bucks on a can of spray.
My advice? For anything you care about – your main army, a centerpiece model, or just a project you want to last – reach for a dedicated Citadel primer. Chaos Black, Corax White, Grey Seer, whatever fits your scheme. If you’re just looking to get a bunch of troops tabletop ready for a casual game and plan on weathering them heavily, then a colour spray might be acceptable. Just don’t expect the same rock-solid adhesion.
Ultimately, understanding the difference between a paint designed to be a colour and a paint designed to prepare a surface for colour is key. Invest in the primer, and your paint jobs will thank you for it in the long run.
