10 Best Primers For Miniatures in 2026

Compared to the Army Painter Classic Zenithal Primer Set, which includes both black and white cans for a two-step highlight method, this single white can offers a simpler approach. Hobbyists who prefer a straightforward white undercoat without switching cans mid-project will find it convenient. Owners mention that spray cans require some practice to avoid overspray, but the trade-off is faster application than brushing.

Black primer is the default choice for miniature painters who want shadows to build naturally under lighter coats, and this spray from Games Workshop delivers exactly that. It is a dedicated black undercoat spray, branded as a primer for models. Starting with a dark base means you can drybrush or layer lighter colors over it and let the recesses stay dark, which saves time on shading. For anyone painting armies of space marines or fantasy figures, a black undercoat gives a gritty, battle-ready look from the first brushstroke.

A spray can like this one doesn’t let you feather paint into recesses the way an airbrush does, so you need to watch for overspray on delicate details. The Army Painter Classic Zenithal Primer Set includes both black and white cans, but Chaos Black locks you into a single tone. That makes it a better fit if you always prime black and want a reliable, no-mix option straight from the shelf.

This set gives you two 400 mL spray cans, one black, one white, specifically paired to create smooth light-to-dark transitions for zenithal highlighting. The fine pigment formula ensures excellent surface preparation and paint adhesion. It’s a straightforward way to apply a black-and-white primer layer for contrast definition without needing to mix or use an airbrush.

The trade-off is that you’re buying two cans to do one job, so if you only prime in a single color, a standalone can like the Citadel White Scar Spray Primer might be simpler. But if you regularly use zenithal priming, having the matched pair gives you a dedicated black and white set designed for that technique. The fine pigment formula also helps prepare the surface for subsequent paint applications.

An 8-ounce bottle gives you enough gray primer to basecoat a whole army or a series of large craft builds without needing to restock mid-project. The neutral gray tone creates a middle-value foundation that works equally well under bright whites, deep reds, and dark metallics, so you can switch color schemes without switching primers. This primer is designed for use on plastic, resin, and metal surfaces, providing a uniform base coat that enhances paint adhesion.

This is a liquid bottle, not a spray can. The 8-ounce container measures 2 by 2 by 6 inches, so it will take up some shelf space. If you only prime one miniature at a time, a smaller bottle like the Vallejo Surface Primer Grey in its 0.6 oz size may be more convenient. But for volume and versatility, this primer delivers consistent adhesion and coverage across multiple surfaces.

This primer is formulated for airbrushing and dries quickly to a hard, resistant matte film within a few hours. It can be thinned with Vallejo Airbrush Thinner or Flow Improver, and the recommended compressor setting is around 15-20 PSI. The 18 ml bottle with dropper is one of several sizes available, so you can pick the volume that fits your project. The acrylic formula cleans up with water or airbrush cleaner, making it a practical choice for anyone who primes with an airbrush.

The primer must be applied to a degreased surface, so you have to wash your miniature to remove release agents before painting; skipping that step can cause poor adhesion. For airbrush users, this Vallejo primer offers precise control at recommended compressor settings of 15-20 PSI, but it does require an airbrush and a bit more prep than a spray can. If you already own an airbrush and value precision over speed, this is a primer to consider.

Three 250 ml bottles of black, gray, and white primer let you switch between base tones without mixing or buying separate cans. Each is pre-diluted and ready to spray through an airbrush, saving time and reducing waste. The matte finish provides a smooth surface that helps topcoats adhere, and the primer works on plastic, resin, metal, and wood, covering many common modeling materials in one purchase.

If your compressor delivers less than 20 liters per minute, you will need to thin the primer yourself, adding an extra step. Brushing is possible, but the primer is designed for airbrush use for best results. This set gives you three colors in one package, which can be convenient if you have an airbrush.

A single coat of this primer fills sanding marks from 800-grit paper and leaves a 1200-grit finish, so metallics and gloss paints lay down without texture. The high-density pigments cover seam lines and color inconsistencies in one pass, saving time on large projects. It bonds to ABS, PS, and resin, even in recesses and on thin parts, keeping your top coat from cracking or flaking. For anyone airbrushing high-detail work, this gives a smooth foundation for fine finishing.

This primer is designed for airbrush use only, with no spray can version. That means it requires an airbrush setup, which is less convenient than a spray primer like Citadel White Scar if you just want to quickly undercoat a batch of miniatures. But if you have an airbrush and value a smooth finish that works well as a base for metallics, the Gaahleri offers a surface quality that spray cans may not match.

A 180ml spray can formulated for ABS and Styrene plastic means this primer is designed to bond with the materials most model kits are made from. The light gray finish provides a neutral base for painting. For anyone building plastic model kits, this primer is made for the job.

The 180ml can is smaller than the 400ml spray primers from Army Painter or Vallejo listed in this guide. If you are priming many models, you will need to buy more cans. But for the model builder who wants a primer made for ABS and styrene, this product fits that need.

A 400 ml can of acrylic spray that primes and basecoats in one pass means you can skip a separate priming step and move straight to painting. The uniform grey tone works as a neutral foundation for historical uniforms, military vehicles, and fantasy or sci-fi miniatures, so it’s a versatile starting point whether you plan to layer lighter or darker colors on top. The matt finish and fine spray are designed to hold onto sculpted detail while giving you a smooth surface for Warpaints Fanatic, Speedpaint, or other acrylics.

You’ll need to apply several thin coats in short bursts, letting each dry before the next, to avoid pooling or obscuring fine detail. That extra attention during application is worth it if you want a single product that does double duty. Compared to a dedicated primer like Citadel White Scar Spray, this one saves you a basecoat step but demands more care with your spray technique to get that even, detail-friendly finish.

The dual-nozzle design is the standout feature here: a low-discharge nozzle for precise work on small details and a medium-discharge nozzle for larger surfaces, all in one can. That means you can switch between priming a tiny shoulder pad and a vehicle hull without grabbing a different product. The self-levelling matt finish dries fast and respects fine detail, which matters when you are trying to preserve crisp edges on a miniature. This spray is formulated for metal, plastic and resin, so it covers the materials most modelers work with. It suits anyone who wants flexibility from a single can and values a consistent finish that matches Vallejo’s brush-on paint lines.

Black is the only color you get, which limits your undercoat options if you prefer gray, white or colored primers for zenithal or contrast techniques. The Army Painter Classic Zenithal Primer Set gives you both black and white in separate cans for a two-step approach, while this Vallejo can gives you one color with two spray patterns. If black is your go-to and you like having nozzle control without buying separate cans, this is a practical pick.
