Can the 3D Finish Coating Be Painted Over?

If you’ve coated your 3D printed object with 3D Finish, you may be wondering whether you can still paint over it. Fortunately, the coating has been designed to create a smooth and paintable surface, making it simple to add further colour or detail to your model.

What Paints Work Best on 3D Finish?

The 3D Finish coating is compatible with acrylic paints and most paints designed for hobby or model use. These paints adhere well to the cured epoxy layer and are widely available in various finishes. For best results, opt for water-based acrylics, as they dry quickly and are easy to layer. Always allow the 3D Finish to fully cure before application, and consider a light sanding with fine-grit sandpaper to help paint grip, especially on glossy areas.

Practical Painting Steps

Ensure the coated surface is completely dry and cured before painting.
Slightly sand the surface (if needed) to promote adhesion.
Clean away dust and any oils before painting.
Apply a primer suitable for plastics or resin if extra grip is required, particularly on intricate details.
Use thin, even coats of paint to build up the desired look without obscuring detail.

Once the paint is dry, an optional clear sealant can be used to protect your design.

If you’re interested in versatile colour effects for epoxy projects, consider the Colourfun Set – Liquid Epoxy Resin Colourant, which is excellent for solid and translucent finishes.

When This Matters

Painting over 3D Finish is particularly useful for those seeking a professional finish on their prints, custom displays, wargaming miniatures, or artistic projects where a smooth, paint-ready base is essential. It allows for both subtle shading and vivid designs on 3D models.
