Painting on resin is no easy task to get right. However, the smooth and unique surface for painting does allow you to achieve some creative and fun new effects.

This gives you more room for experimenting and getting things just the way you want them.
How to Paint Resin: Step-by-Step Guide
When you paint resin, the process is different from painting on traditional surfaces like a canvas. For this reason, a few critical steps need to be followed in order to make sure you get good results. This starts by preparing the resin surface properly and then using the right type of paint for the project.
Cleaning the Resin
The first thing to do is to make sure that the surface of the resin is clean. Sometimes, there will be some dirt or residue remaining from the casting process. Using warm soapy water, you can clean up the resin pretty easily. Make sure that it is completely dirt and dust-free before proceeding.
When the resin is cast, flash can occur. This is when some pieces of dried resin can find a place between the halves of a mold. When this happens you often don’t notice it, but it is easily spotted when painting on resin. Flash can be removed with a craft knife, and the resin surface should be sanded down completely. The smoother and more even the resin is the better.
Fill in Holes
If there are any imperfections in the resin that occurred during the casting process – such as air bubbles or holes, these will need to be filled in. Epoxy putty can be used to do this, as it will bond well with the resin. Once cured and filled in, you can sand down the putty to achieve a perfectly smooth and even surface.
Once the surface is smooth, clean, sanded, and ready, you will have to apply a layer of primer. This is necessary for painting on resin, as the resin is such a smooth surface. Without a primer, the paint will not be able to adhere very well to the resin. Making sure that the primer is on properly is one of the most important steps when you paint resin models.
You can get primers in various colors. This should be chosen depending on the color you will be painting with. Light colors are best with a light primer, dark colors work with a dark primer, and so on. Usually, white or grey primers are preferred as these work with most paint colors.
Primers can come in a spray or brush-on form. Spray on primers are best, as these allow you to get a perfectly even coating. They are also good for getting into any details and hard to reach places. Spraying on the primer offers you more control and results in a smoother finish compared to brushing it on.
Primers should be sprayed in a well-ventilated area as they can cause some fumes in the air. You will probably need a few layers of primer depending on the particular conditions. Just make sure that each coat is dried properly before a new layer of primer is added. Many people will and the primer between coats for a stronger finish.

When preparing resin models, the same preparatory steps need to be followed. Clean the model, prime it, and have it ready for painting. Here are some extra tips to help make a painting on resin models easier.
- Start painting the larger surfaces and then move onto smaller details. Models can have many fine details, so getting them painted properly is important. Make sure to get the right brush. A small and flat brush will help to get the finer details without leaving any brush marks.
- You should also start with lighter colors and move on to darker shades. This is because making colors darker is easy by just painting them over in a darker shade, but painting colors lighter is more difficult. This works out because the darker colors usually end u[p in the smaller, detailed places anyway.
- Finally, end the model painting off with a very fine brush. Use it to get to the smallest details and definitions of the model. It is the final little dark lines, shadows, and details that will really give the model its character. Once dried, finish the model off with a suitable sealer, Using a spray-on version is definitely recommended for the small and uneven figure.
