Proper priming is the foundation of a successful paint job on resin models. A well-prepared surface ensures paint adheres smoothly and offers a professional, durable finish.
Why Priming is Essential for Resin Models
Resin surfaces are typically non-porous and may carry release agents or minor imperfections from the printing process. Priming not only improves paint adhesion but also highlights surface details and minimises issues like peeling or flaking. For best results, always clean your model thoroughly before you begin, removing dust and any oily residues.
Steps to Achieve a Smooth, Paint-Ready Surface
- Clean the model: Wash with mild detergent and ensure it’s fully dry.
- Lightly sand: Use fine-grit sandpaper to gently smooth out layer lines and blemishes, being careful not to remove detail.
- Apply a suitable surface coat: A dedicated finishing product such as the “3D Finish” – Fast Coating Epoxy Resin for 3D Prints can seal your model, level out irregularities, and provide a solid foundation for paint.
- Choose the right primer: After your base layer has cured, use a quality primer compatible with resin surfaces. Apply in thin, even coats for best coverage.
When This Matters Most
Priming is especially important if you plan to use light colours, highlight fine details, or handle your painted models regularly. A strong foundation prevents chipping and ensures a flawless, long-lasting finish.
