How to Paint Warhammer 40k Miniatures, From Basics to Advanced ...

Stripping paint from miniature wargaming models involves a chemical process that breaks the bond between acrylic polymers and plastic or metal substrates without compromising structural integrity. By utilizing high-purity isopropyl alcohol or specialized non-caustic stripping agents, hobbyists can safely recycle models to achieve a factory-clean surface ready for repainting.


Establishing Your Stripping Environment and Necessary Materials

Successfully removing paint from Warhammer models requires a methodical approach to chemistry and mechanical scrubbing. Before initiating the process, you must account for the material composition of your miniatures, as polystyrene plastic, resin, and white metal react differently to various solvents. Plastic models are prone to melting or warping if exposed to harsh industrial chemicals like acetone, which is why chemical selection is the primary safety filter in this process.



Essential Equipment Checklist



  • Solvent Selection: 99% Isopropyl Alcohol (IPA) is the industry standard for plastic. Methylated spirits or specialized proprietary strippers like Biostrip 20 are effective for thick, multi-layered paint jobs on metal.
  • Mechanical Tools: A medium-to-firm bristle toothbrush, dental picks or cocktail sticks for detail work, and a plastic container with a secure lid to prevent solvent evaporation.
  • Safety Gear: Nitrile gloves to prevent skin irritation and chemical absorption, and protective eyewear to guard against solvent splashes during vigorous scrubbing.
  • Workspace Requirements: A well-ventilated area, preferably near an open window or with a fan, to disperse solvent fumes.
  • Material Benchmarks: Budget roughly 15 to 30 minutes of active labor time per batch, though chemical soaking times can vary from two hours to overnight depending on paint thickness.

Standard Operating Procedure for Paint Stripping

Executing a clean strip requires patience. Rushing the process often results in residual paint lodged in deep recesses or the accidental destruction of fine surface details like rivets or filigree.



Step 1: Pre-Soaking and Surface Penetration

Submerge the models completely in your chosen solvent. If using 99% Isopropyl Alcohol, ensure the container is airtight; if the alcohol evaporates, the pigment will re-settle on the model, creating a sticky residue that is harder to remove than the original paint. Let the models soak for a minimum of 60 minutes for basic paint jobs. For models caked in multiple layers or heavy enamel washes, a 12-hour soak is recommended.



Step 2: Mechanical Agitation

Remove the model from the solvent bath. While the model is still wet with the stripping agent, use the toothbrush to scrub the surfaces in circular motions. Focus on flat panels first, then move to recessed areas. You will notice the paint lifting as a viscous sludge.

Warning: Never use acetone or nail polish remover on plastic miniatures. Acetone will chemically fuse with polystyrene, resulting in a soft, melted surface that permanently obscures molded details.



Step 3: Targeted Detail Cleaning

After the initial scrub, utilize a dental pick or a sharpened cocktail stick to clear paint from intricate areas such as chainmail, weapon barrels, or facial features. If the paint remains stubborn in deep crevices, return the model to the solvent for an additional hour and repeat the brushing process.



Step 4: Neutralization and Drying

Once the paint is removed, rinse the model thoroughly under warm, running water. A mild dish soap can be used during this rinse to neutralize the remaining chemical scent and strip away any lingering oily residue. Allow the miniature to air-dry completely on a paper towel for at least 24 hours before applying new primer. If the surface feels tacky, it indicates the solvent has not fully evaporated from the plastic pores.

Technical Comparison of Stripping Agents

Selecting the right agent depends on the volume of models, the material, and your specific safety requirements.



Stripping Agent Surface Safety Effectiveness Best Use Case
99% Isopropyl Alcohol Excellent (Plastic/Metal) High Rapid, standard plastic model stripping
Biostrip 20 Excellent (All materials) Superior Thick layers, resin miniatures, metal models
Simple Green Moderate (Safe) Moderate Long-term soaking (24-48 hours)
Acetone Dangerous (Melts Plastic) Extreme Metal miniatures ONLY
Brake Fluid Poor (Toxic/Hazardous) High Legacy methods (Not recommended for health)

Common Field Failures and Remediation Strategies

Even with careful execution, complications arise due to varying paint types and model quality. Understanding the root cause ensures you do not damage your collection beyond repair.



  • Issue: The paint has turned into a sticky, impossible-to-remove gum.

    • Root Cause: Incomplete soaking or using a solvent that is too weak for the specific acrylic binder.
    • Actionable Fix: Re-submerge the model in fresh 99% Isopropyl Alcohol for an additional six hours to fully dissolve the binder matrix.
  • Issue: Fine details appear "fuzzed" or slightly rounded.

    • Root Cause: Mechanical over-scrubbing with a brush that is too stiff, or the usage of harsh chemicals like acetone on plastic.
    • Actionable Fix: Use a softer brush in the future and strictly avoid acetone. Unfortunately, structural surface deformation is often permanent.
  • Issue: Primer residue remains in the deepest recesses.

    • Root Cause: Primer is engineered to bond directly to plastic, making it more resilient than base coats.
    • Actionable Fix: Utilize a pointed dental tool to mechanically scrape the remaining primer once the paint has been loosened; do not rely on chemical stripping alone for industrial primers.

Frequently Asked Questions



Can I strip paint from resin models using the same methods?

Yes, but exercise extreme caution. Resin is more porous than plastic and can become brittle if left in solvents for extended periods. Stick to high-quality proprietary strippers and limit soak times to under two hours, rinsing immediately after scrubbing.



Will these methods damage the superglue holding my model together?

Yes. Most solvents used for stripping paint will also break the bond of cyanoacrylate (superglue). If your models are assembled with plastic glue, they will remain intact; however, if they are pinned or superglued, expect them to disassemble during the process.



Is it safe to pour the used solvent down the drain?

No. Solvents like isopropyl alcohol and paint residues should not be disposed of in the sewer system. Store the used liquid in a sealed container and take it to your local household hazardous waste collection site.



How many times can I reuse the stripping solution?

You can reuse 99% Isopropyl Alcohol until it becomes noticeably cloudy with dissolved pigment and loses its cleaning efficacy. Once the fluid is saturated with paint particles, it will no longer effectively strip new models and should be recycled according to local regulations.
