How to Paint Resin Models

Posted on: July 23, 2022

If you’re wondering how to paint resin models, keep reading. There are some general steps that apply to all resin models. First, wash them with soap and water. Once they’re completely clean, sand them down, and prime them, you’re ready to paint! Afterward, you can apply acrylic paint. It is recommended that you use acrylic paint if you want vibrant colors. To prepare resin models for painting, follow these steps:

Acrylic paint produces vibrant hues

Acrylic paint is a dye-based medium with a large range of colours. These are typically available in ready-to-use colours. As such, they do not behave like true pigments when mixed. Acrylic paints are excellent for a wide range of applications, including painting on wood, air-dried clay, and non-porous surfaces. Some specialist formulations are also available for painting metals.

Acrylic paint is a non-toxic medium and is safe for indoor use. It is also excellent for workpieces requiring attention to detail. Because it produces such vibrant hues, it’s the perfect medium for painting resin kits. In addition to being non-toxic, acrylic paint is also safe for children and indoor projects.

Styrene adhesive

If you are planning to build a model using styrene for walls and other parts, you should take the time to prepare the styrene sheets well before you start working on the finished model. Using a scale ruler is recommended as it will not leave a “0” mark on the edge of the plastic. You can also use a compass or a French curve to lay out curved lines on the styrene sheet.

Resin kits are generally made from two-part plastic, which makes it easier to see detail than styrene. They are also made of two-part plastic that is mixed together before hardening. When painting resin kits, you can use regular styrene glue to assemble the parts, but make sure to clean your workspace with a degreaser before applying the glue.

Epoxy resin paint

If you are wondering how to paint an epoxy resin kit, you will need to follow the instructions carefully. The kit contains two parts, the hardening and seal coats. The first is used as a seal coat and helps to prevent air bubbles from forming. The second part is known as the flood coat and flows self-leveling. Use a clean brush to apply the flood coat and spread it evenly. One or two coats of epoxy resin will cover about 2 square feet.

First, clean the surface of the resin. If the surface is smooth, there should be no residual flash from the casting process. Residual flash is the result of resin that runs into the joint between the two mold halves. When the model is painted, this residual flash will form a ridge. To prevent this ridge, smooth the surface with an 800-grit sandpaper. Once dry, apply paint lacquer and allow the resin to cure.


You may think that sanding resin kits is not an essential step. After all, the dust produced isn’t good for your health. Nonetheless, sanding your resin kits is necessary for proper fit and painting. Read on for some helpful tips. You can begin the process by cleaning the parts with a good dish detergent. If you don’t have one, you can use an old toothbrush to scrub the parts. If you notice that the resin is still squeaky, it’s time to clean it.

Before applying the resin, you need to wet it first. There are several ways to do this, the most common method involves using a spray bottle of water. The sanding is usually done manually, so it’s better if you avoid using electrically operated machines as they may cause an electric shock. However, you can use an air-powered sander if the surface is very large. It will ensure a perfect finish, but it requires a lot of time.

Cleaning release film

There are several different ways to clean a resin kit’s release film. A simple method is to use acetone, which can be bought at most hardware stores. Pour some acetone in a small glass container and scrub the resin part with a fine-hair paint brush. Rinse thoroughly with warm water and dish soap. Once the release film has been removed, you can dry the part on a paper towel. Do not use too much acetone, as it will dissolve the plastic.

When cleaning a resin kit’s release film, make sure to use a mixture of 91% IPA and glass cleaner. While cleaning, hold a bright light at a low angle. Use the light to shine across the tank surface to check for colored streaks. If any color remains on the film, the resin has not been removed properly. To get the most thorough results, carefully follow the manufacturer’s instructions for cleaning release film.


Before painting your resin kit, you must use primer. A primer is a thin layer of paint that prepares the surface of your resin kit for paint. To prep your resin surface for paint, you must first clean it with mild soap to remove silicone oils and mold release. After cleaning the surface, spray the model with your favorite primer. We at Johnnycrash like to use sandable scratch-filling automotive etching primer because it is cheap, easy to find, and does a good job of leveling.

Generally, you can use primer in three different colors. White, black, and grey are the most common colors, but the grey one is slightly more difficult to find. Select the color of primer based on the paint color you plan to use. Use black if you plan to paint the model with a dark color. For lighter colors, choose white. And for models with lots of mixed colors, choose grey. Whether you choose a paint-on or a spray-on primer, make sure you wait for the primer to dry completely before you start painting.
