Priming is the step that determines how good your paint job will look and how long it will last. Even perfectly assembled and cleaned resin miniatures can fail at the painting stage if priming is rushed or done incorrectly.
In this guide, we explain how to prime resin miniatures step by step, using simple techniques that work for beginners and experienced hobbyists alike.
Why Priming Resin Miniatures Is Important
Resin has a smooth surface that paint does not naturally stick to. Primer creates a thin, textured layer that allows paint to adhere properly.
Without primer:
-
paint may peel or chip
-
colors apply unevenly
-
details can look flat
Priming is not optional. It is the foundation of every successful paint job.
What You Need Before Priming
Before you start, make sure the miniature is:
-
fully cleaned
-
completely dry
-
assembled and inspected
You will also need:
-
primer (spray, airbrush, or brush-on)
-
a holder or handle for the miniature
-
a clean, well-ventilated workspace
Step 1: Mount the Miniature
Mounting the miniature prevents fingerprints and gives better control.
Common mounting options:
-
cork with a pin
-
bottle cap with adhesive
-
painting handle
Always hold the base or the handle, not the miniature itself.
Step 2: Choose the Right Primer Color
Primer color affects how your paint will look.
-
Gray is the safest and most versatile choice
-
Black works well for dark or gritty schemes
-
White is best for bright and vibrant colors
If you are unsure, start with gray.
Step 3: Apply Primer in Thin Coats
The most important rule of priming is to apply thin, even coats.
If using spray primer:
-
shake the can well
-
spray from about 8–12 inches away
-
use short, controlled passes
-
rotate the miniature between passes
Do not try to cover everything in one go.
If using airbrush or brush-on primer:
-
apply light layers
-
avoid pooling in recesses
-
build coverage slowly
Step 4: Let the Primer Dry Properly
After priming:
-
let the model sit undisturbed
-
avoid touching the surface
Typical drying times:
-
touch dry: 20–30 minutes
-
fully cured: 12–24 hours
Painting too early can damage the primer layer.
Step 5: Inspect the Primed Model
Once dry, inspect the miniature under good lighting.
A properly primed model should:
-
have an even, matte surface
-
retain all fine details
-
show no glossy or wet spots
If details look filled in, the primer was applied too thick.
What to Do If Primer Goes Wrong
If primer:
-
looks grainy
-
fills details
-
goes on unevenly
You can:
-
strip the primer using isopropyl alcohol
-
gently scrub with a soft brush
-
rinse, dry, and reapply primer in thinner coats
Resin miniatures can be reprimed safely when handled correctly.
Common Priming Mistakes
-
skipping cleaning before priming
-
spraying too close
-
applying thick coats
-
painting before the primer cures
Avoiding these mistakes makes a big difference.
Final Thoughts
Priming resin miniatures is a simple process when done patiently. Thin coats, proper drying time, and the right primer color ensure that paint adheres well and details stay sharp.
A good primer layer sets you up for an enjoyable and successful painting experience.
