Chemical Stripping Methods: Safe, effective solvents for resin; application tips; neutralizing residue
Chemical stripping offers a direct approach to removing paint from Forge World resin models, leveraging solvents to break down layers without damaging the delicate details. Among the safest and most effective solvents for resin are Simple Green (a biodegradable cleaner) and isopropyl alcohol (at least 91% concentration). Simple Green is gentle yet powerful, requiring a 1:3 dilution with warm water for optimal results. Isopropyl alcohol, on the other hand, acts faster but demands caution due to its flammability. Both solvents are readily available and affordable, making them ideal for hobbyists seeking efficiency without harsh chemicals.
Application technique is critical to success. Submerge the resin model in the solvent mixture, ensuring full coverage, and let it soak for 24–48 hours. For stubborn paint, gently agitate the solution with a soft-bristled brush every few hours to loosen particles. Avoid using metal tools, as they can scratch the resin surface. After soaking, remove the model and use a toothbrush or cotton swab to scrub away remaining paint, working in the direction of the model’s details to preserve them. Patience is key—rushing this step risks incomplete stripping or surface damage.
Neutralizing residue is essential to prevent solvent remnants from affecting future paint adhesion. After stripping, rinse the model thoroughly under running water, then soak it in a mixture of warm water and mild dish soap for 15–20 minutes. This step removes any oily traces left by the solvent. For added assurance, a final rinse with distilled water eliminates mineral deposits that could interfere with priming. Once clean, allow the model to air-dry completely before priming or painting, ensuring a pristine surface for your next project.
While chemical stripping is effective, it’s not without risks. Always work in a well-ventilated area and wear nitrile gloves to protect your skin. Store solvents in a cool, dry place, away from open flames or heat sources. For intricate models, consider spot-testing the solvent on a small area first to ensure compatibility. By following these steps and precautions, you can safely and effectively strip paint from Forge World resin, restoring your models to their original glory.

Mechanical Removal Techniques: Tools like scrapers, brushes, and sandpaper for manual paint stripping
Mechanical removal techniques offer a hands-on approach to stripping paint from Forge World resin models, relying on tools like scrapers, brushes, and sandpaper. This method is particularly appealing for those who prefer precision and control over chemical alternatives. However, it requires patience and a gentle touch to avoid damaging the intricate details that make Forge World models unique.
Tools and Techniques:
Start with a soft-bristled brush to remove loose paint flakes gently. For stubborn areas, a plastic scraper is ideal—its flexibility prevents scratching the resin surface. Avoid metal scrapers, as they can gouge delicate details. For textured or hard-to-reach areas, fine-grit sandpaper (400–600 grit) works effectively. Wrap the sandpaper around a small wooden dowel or your fingertip for better control. Always work in the direction of the model’s details to preserve its integrity.
Steps for Success:
- Prepare the workspace: Lay down a protective surface and have a container of warm water nearby to clean tools as you work.

Ultrasonic Cleaning Process: Using ultrasonic cleaners to gently lift paint without damaging resin
Ultrasonic cleaning offers a precise, non-invasive method for stripping paint from Forge World resin miniatures, leveraging high-frequency sound waves to agitate cleaning solutions and dislodge paint particles without mechanical abrasion. Unlike traditional methods such as scrubbing or soaking in harsh chemicals, this process minimizes the risk of damaging delicate resin details, making it ideal for intricate models. The ultrasonic cleaner’s cavitation effect—tiny bubbles forming and collapsing in the cleaning solution—gently lifts paint from surfaces, even in hard-to-reach areas like recessed details or fine textures.
To begin, select an ultrasonic cleaner with a capacity suitable for your miniature size, typically ranging from 0.8 to 3 liters for hobbyist use. Fill the cleaner’s tank with a mild cleaning solution; simple green diluted 1:10 with water is effective, or opt for specialized miniature paint strippers designed for ultrasonic use. Submerge the resin model fully, ensuring no parts are exposed to air, as this can hinder the cavitation process. Set the cleaner to a low-to-medium frequency (40–60 kHz) and run it for 10–20 minutes, depending on paint thickness. Avoid prolonged cycles, as excessive exposure to the cleaning solution may soften the resin.
While ultrasonic cleaning is gentle, precautions are essential. Always wear gloves when handling cleaning solutions, and ensure proper ventilation to avoid inhaling fumes. After the cycle, rinse the miniature thoroughly in warm water to remove residue, then inspect for remaining paint. Stubborn areas can be treated with a soft brush or additional ultrasonic cycles, but avoid metal tools that could scratch the resin. For best results, use distilled water in the cleaner to prevent mineral buildup, and clean the tank regularly to maintain efficiency.
Comparatively, ultrasonic cleaning stands out for its ability to preserve fine details, a stark contrast to manual stripping methods that often risk damaging resin. It’s particularly advantageous for Forge World models, which frequently feature intricate designs and fragile components. While the initial investment in an ultrasonic cleaner may be higher than traditional tools, its efficiency and precision make it a valuable addition to any hobbyist’s toolkit. Paired with proper care and the right cleaning solution, this method ensures your resin miniatures are restored to their original state, ready for repainting without compromise.

Preventing Resin Damage: Avoiding heat, harsh chemicals, and excessive force during stripping
Resin models, particularly those from Forge World, are prized for their intricate details and high-quality casting. However, their delicate nature makes them susceptible to damage during the paint stripping process. Heat, harsh chemicals, and excessive force are the primary culprits that can warp, melt, or crack the resin, rendering your model irreparable. Understanding how these elements interact with resin is crucial to preserving its integrity while effectively removing old paint.
Heat, for instance, is a common mistake many hobbyists make. Applying heat to soften paint—whether through a heat gun, hairdryer, or hot water—can quickly exceed resin’s thermal threshold. Resin typically begins to deform at temperatures above 70°C (158°F), and prolonged exposure to even lower temperatures can cause stress fractures. Instead of heat, opt for mechanical methods like gentle scraping with a soft-tipped tool or a toothbrush. For stubborn areas, use a fine-grit sanding sponge (400–600 grit) to avoid scratching the surface. Always test on a small, inconspicuous area first to ensure the resin can withstand the pressure.
Harsh chemicals are another significant risk. Solvent-based strippers like acetone, lacquer thinner, or brake fluid can dissolve not only paint but also the resin itself, especially if left on for too long. Even "safe" options like Simple Green or isopropyl alcohol can weaken the resin over time. If chemical stripping is necessary, dilute the solution to a 1:1 ratio with water and limit exposure to no more than 10–15 minutes. Afterward, rinse the model thoroughly with warm water and allow it to air dry completely before inspecting for damage.
Excessive force is perhaps the most avoidable yet common cause of resin damage. Aggressive scrubbing or prying at paint can snap off delicate details or leave unsightly gouges. Always work with a light touch, using tools designed for precision, such as dental picks or silicone-tipped probes. For recessed areas, a soft-bristled brush dipped in soapy water can dislodge paint without harming the resin. Patience is key—multiple gentle sessions are far safer than a single forceful attempt.
By avoiding heat, harsh chemicals, and excessive force, you not only protect your resin model but also ensure it remains a viable canvas for future projects. The goal is to strip paint, not compromise the material. With careful technique and the right tools, you can preserve the intricate details that make Forge World models so desirable, allowing you to repaint and reimagine them without fear of damage.

Post-Stripping Preparation: Cleaning, priming, and repairing resin for repainting or detailing
After stripping paint from Forge World resin, the surface may appear clean but often retains residues or microscopic debris that hinder adhesion. Use a soft-bristled toothbrush and mild dish soap to scrub every crevice, ensuring no chemical remnants or grease remain. Rinse thoroughly with warm water and allow the model to air-dry completely. For intricate details, a gentle stream of water from a syringe or a quick dip in an ultrasonic cleaner can dislodge stubborn particles. This step is non-negotiable—skipping it risks poor paint adhesion and a compromised finish.
Priming is the bridge between stripped resin and new paint, but not all primers are created equal. Choose a primer specifically formulated for plastic or resin, such as Citadel’s Grey Seer or Army Painter’s Ultra primer. Apply thin, even coats from 6–8 inches away, holding the spray can perpendicular to the surface. Multiple light layers are better than one heavy coat, which can obscure details. Allow 15–20 minutes between coats and 24 hours for full curing. For brush-on primers, dilute slightly with water or flow improver to avoid obscuring fine details, and apply in smooth, even strokes.
Stripping processes can warp or damage delicate resin, particularly on older models. Inspect the piece for cracks, chips, or softened areas, and repair them with a two-part epoxy putty like Green Stuff or Milliput. For small gaps or pitting, use a thin layer of superglue mixed with baking soda for a quick, durable fill. Sand repaired areas with 400–600 grit sandpaper, working in one direction to maintain surface consistency. Always wear a mask during sanding to avoid inhaling resin particles, and wipe the model with a tack cloth to remove dust before priming.
Detailing post-stripping offers an opportunity to enhance the model’s character. Use a fine-tipped brush and thinned paint to pre-shade recessed areas, adding depth before the final paint job. Apply a gloss varnish to areas where decals will be placed to improve adhesion, or use a matte varnish to unify the surface texture. For models with exposed metal components, consider dry-brushing with a metallic paint to restore their luster. Each step, from cleaning to detailing, ensures the resin is not just ready for paint but optimized for a professional-grade finish.
