Assessing the Break and Identifying the Broken Pieces
When you discover a broken resin miniature, your first step is to carefully examine the damage. Look at where the break occurred and identify all the pieces involved. This determines which repair method will work best for how to fix broken resin miniatures.
Start by laying out all broken fragments on a clean surface. Check if pieces are missing entirely or if you have all the parts. Missing pieces mean you'll need a different approach than a clean break where both sides are present. Run your fingers gently along the break edges to feel if they're jagged or smooth. Jagged breaks often hold adhesive better because they create more surface area for bonding.
Take note of the miniature's size and weight. Tiny pieces like sword tips or small details need a different adhesive than larger structural breaks. A lightweight resin piece that broke at a joint needs reinforcement differently than a thick base that snapped in half.
Preparing and Cleaning Broken Surfaces
Proper surface preparation is essential before applying any adhesive. Dust, debris, and residue prevent glue from bonding effectively, so you need to clean the broken surfaces thoroughly. However, resin requires careful handling because some solvents can damage the material, and sanding generates fine particles that pose inhalation risks.
Cleaning Unpainted Resin
Use a soft brush or cloth to remove loose dust and particles from the break area. For stubborn residue, a slightly damp cloth works well, but let the pieces dry completely afterward, any moisture on the surface will weaken adhesive bonding.
For unpainted resin, you can use fine-grit sandpaper (220-grit or higher) to roughen the surface slightly. This improves adhesive grip without removing material. Sand very lightly in one direction across the break edge, using minimal pressure. Wipe away all sanding dust with a clean, dry cloth before moving to the gluing stage.
Important: Sanding resin generates fine particles that can irritate airways if inhaled. When sanding, work in a well-ventilated area or outdoors. Consider wearing an N95-rated dust mask if you're sanding multiple pieces or have respiratory sensitivity. Never sand resin in an enclosed space without ventilation.
Cleaning Painted or Primed Miniatures
If your miniature has paint or primer, skip the sanding step entirely. Sanding will remove the finish and expose bare resin, creating a visible repair line even after gluing. Instead, use a dry brush to gently remove loose dust and inspect the break carefully to ensure no paint flakes are loose or peeling.
For painted miniatures, protect the finish during repair by masking off the break area with painter's tape before applying adhesive. Alternatively, use a toothpick or small applicator to apply super glue or epoxy precisely to the break surfaces only, avoiding contact with the painted areas.
Solvent Cautions for Resin
Do not use acetone, alcohol, or other strong solvents to clean resin miniatures. Resin formulations vary widely, some are sensitive to acetone or other solvents, which can soften, discolor, or damage the surface. If you're unsure whether a miniature will tolerate a solvent, test it on an inconspicuous area first, or stick to water and a soft brush.
For sticky residue or old glue on the break surfaces, use warm water and a soft cloth. If residue persists, a very gentle rub with fine-grit sandpaper (400-grit or higher) on unpainted resin is safer than chemical solvents.
Choosing the Best Glue for Resin Miniatures
Selecting the right adhesive is crucial when you fix broken resin miniatures. Different glues work better for different types of breaks, resin types, and the stress the joint will experience. Understanding your options and the trade-offs between them helps you make the right choice for your specific situation.
Adhesive Comparison by Break Type and Load
Super Glue (Cyanoacrylate) works best for small, clean breaks on low-stress joints, such as a snapped sword blade, a detached hand, or a thin decorative element. It bonds almost instantly (30-60 seconds), requires no clamping, and is ideal for miniatures you'll display but rarely handle. The downside is brittleness; the bond will eventually shatter if the joint flexes or experiences repeated stress. Super glue also struggles with irregular or jagged breaks because it doesn't fill gaps.
Two-Part Epoxy creates a stronger, more flexible bond and is the better choice for structural breaks, such as a leg snapped at the hip joint, a torso broken at the waist, or a base that cracked in half. Epoxy fills small gaps better than super glue and cures to a slightly flexible state, so it won't shatter under handling stress.
Epoxy Putty is a third option for breaks with gaps or missing fragments. Knead the two-part putty until the color is uniform, then press it into the joint and around the break line. It cures to a solid, sandable state and can be shaped before hardening. Epoxy putty is slower to set than liquid epoxy (typically 24 hours) but offers more control for irregular breaks and allows you to fill voids without liquid overflow.
Quick Decision Guide
- Small, clean break on a non-structural part (sword, staff, thin detail): Super glue, gel formula
- Structural break or joint under handling stress (leg, arm, torso, base): Two-part epoxy with pinning
- Break with gaps or missing material: Epoxy putty, possibly combined with pinning
- Painted miniature (any break type): Use super glue or epoxy, but mask off paint with painter's tape or apply adhesive with a toothpick to avoid stains
How to Pin a Broken Miniature for Reinforcement
Pinning adds mechanical strength to a repair, especially for breaks on thin or delicate parts. A metal pin drilled through the joint creates a structure that holds even if the adhesive eventually fails.
Use a small drill bit (1/16 inch diameter) to drill straight through both pieces at the break point. The hole should go perpendicular to the break line. Measure the depth needed and mark your drill bit with tape so you don't drill too deep.
Cut a piece of wire or a small metal pin slightly longer than the hole depth. Insert the pin into the hole in one piece, then apply epoxy to both the pin and the hole in the second piece. Slide the pieces together, allowing the pin to guide alignment. Clamp or hold in position while the epoxy cures.
For very small miniatures, use thin wire (24-26 gauge) instead of a thick pin. The wire is easier to drill through tiny pieces and creates less stress on fragile resin.
How to Straighten Bent Resin Miniatures
Bent resin pieces can sometimes be straightened, though results vary depending on the bend severity and resin type. Gentle heat can make resin more flexible, allowing you to reshape it carefully.
Boil water and let it cool slightly until it's hot but safe to handle. Submerge the bent piece for 2-3 minutes. Remove it carefully with tweezers and gently bend it back to the correct shape. Hold the position until the resin cools and hardens again.
For severe bends, repeat this process multiple times rather than forcing a single correction. Forcing resin to straighten too quickly can cause cracking.
Essential Resin Miniature Repair Tools
Building a basic repair toolkit makes future fixes much easier. You don't need expensive equipment, most tools are affordable and widely available.
A small hobby drill or rotary tool handles pinning work precisely. Super glue and two-part epoxy are the adhesive essentials. Fine-grit sandpaper (220-grit and 400-grit) prepares surfaces and smooths dried adhesive. Small clamps or rubber bands hold pieces in position while glue cures.
Wire cutters trim pins to the right length. Tweezers help position tiny pieces accurately. A cutting mat protects your work surface from adhesive spills. Disposable gloves keep your hands clean and protect skin from epoxy.
Aligning Pieces Before Bonding and Curing
Correct alignment before the glue sets determines whether your repair looks seamless. Misaligned pieces create visible gaps that ruin the miniature's appearance.
Dry-fit the pieces first without adhesive. Check the alignment from multiple angles. Look for gaps between surfaces and ensure the break line isn't visible. Make small adjustments until the pieces fit perfectly.
Once alignment is correct, apply adhesive and press the pieces together. For super glue, hold for one minute. For epoxy, use clamps or rubber bands to maintain pressure throughout the cure time. Remove clamps only after the adhesive has fully hardened according to the product instructions.
Common Repair Mistakes to Avoid
Using too much adhesive is a frequent error. Excess glue creates messy overflow that's difficult to clean and can damage paint. Apply adhesive sparingly, a thin line is all you need for a strong bond.
Rushing the cure time causes repairs to fail. Even if super glue feels set after a few minutes, it needs several hours to reach full strength. Epoxy requires 24 hours before you handle the repaired miniature. Patience prevents frustrating failures.
Attempting repairs on damaged paint without protection leads to adhesive stains on your finish. Mask off painted areas with painter's tape before gluing, or use a toothpick to apply adhesive precisely without touching the paint.
Skipping surface preparation reduces adhesive strength. Even though it takes extra time, cleaning and roughening break surfaces makes the difference between a repair that lasts and one that fails under normal handling.

Frequently Asked Questions
Can broken resin miniatures be repaired without losing detail?
Yes, broken resin miniatures can be restored while preserving fine details. The key is using the right adhesive and alignment technique. Super glue works well for small, clean breaks, while two-part epoxy is better for larger fractures or gaps. Proper surface cleaning before bonding and careful alignment during curing prevent detail loss. For very small or delicate parts, pinning the joint adds reinforcement without affecting painted surfaces.
What is the best glue for resin miniatures?
Super glue (cyanoacrylate) is best for small, clean breaks on resin miniatures because it sets quickly and doesn't require mixing. Two-part epoxy works better for larger breaks, missing pieces, or joints needing gap-filling strength. Epoxy putty is ideal for very small missing fragments. Always test adhesives on scrap resin first, and avoid solvent-based glues that can cloud or damage resin surfaces. Allow full curing time before handling.
How long should glue cure before handling a repaired miniature?
Super glue typically cures fully in 24 hours, though it sets to the touch within minutes. Two-part epoxy requires 24 to 48 hours for complete curing, depending on the brand. Always check the product instructions, as some formulas cure faster. Avoid moving or painting the miniature until full cure time has passed to ensure the bond reaches maximum strength. Premature handling can weaken the joint or cause misalignment.
Can I repair a resin miniature that arrived damaged from shipping?
Absolutely. Shipping damage is common on detailed miniatures, and most breaks are fully repairable using the methods in this guide. Noble Nerds backs all miniatures with a one-year guarantee, ensuring that replacements are simple and cost-free. However, if you prefer to repair it yourself, super glue or epoxy works well for most shipping breaks. Clean the fractured surfaces, align carefully, and let the adhesive cure fully before painting or handling.
