A highly effective and common method for removing acrylic paint from models is by using isopropal alcohol.
Using Isopropal Alcohol
Isopropal alcohol, also known as isopropyl alcohol or rubbing alcohol, is widely regarded as an excellent solvent for stripping acrylic paints from various model surfaces. It's known to "make short work of acrylic paint."
One practical method involves:
- Preparation: Find a small plastic dish.
- Application: Pour a little isopropal alcohol into the bottom of the dish.
- Immersion: Place the painted part of the model into the dish, ensuring it is submerged in the alcohol.
- Scrubbing: Using an acid brush, gently scrub the part. This action helps to loosen and lift the acrylic paint.
- Removal: The paint should come off without too much difficulty. You may need to repeat the process or use a fresh amount of alcohol for stubborn areas.
This technique is often preferred as it tends to be less aggressive on the underlying plastic or resin compared to some other stripping agents.
Important Considerations & Tips
- Ventilation: Always use isopropal alcohol in a well-ventilated area due to its fumes.
- Safety Gear: Consider wearing gloves to protect your skin.
- Test First: If possible, test the alcohol on a small, inconspicuous area of the model or a spare part, especially if you are unsure of the model's material, to ensure it doesn't damage the surface.
- Brush Type: An acid brush is recommended as its bristles are often stiff enough to scrub paint effectively but may vary in material compatibility. Other stiff brushes or even old toothbrushes can also work.
- Plastic Compatibility: While generally safe for many common model plastics, prolonged exposure or soaking in high concentrations of alcohol can potentially affect some types of plastic. Monitor the process closely.
- Cleaning Up: After stripping, rinse the model part with water to remove any residual alcohol and paint flakes.
By following these steps and tips, you can effectively remove acrylic paint to repaint or restore your models.
