How to Seal and Finish Your Painted Resin Model

Completing your resin model with a proper seal and finish not only enhances its look but also protects your painted surface from wear and daily handling. Here’s a compact guide to getting a lasting result.

Why Sealing Your Painted Model Matters

Sealing creates a protective layer over your artwork, preventing chips, scratches and the effects of frequent use. For painted resin models, applying a clear finish helps lock in your colours and reduces the risk of paint flaking or fading over time.

Choosing a Suitable Sealer

For resin models, select a finish that bonds well to common 3D print plastics. “3D Finish” – Fast Coating Epoxy Resin for 3D Prints is a user-friendly epoxy topping that produces a glossy, smooth surface and preserves model details. It is designed for use with materials like PLA, ABS, and LAYWOOD, making it ideal for both hobbyists and professionals.

Applying and Curing Your Finish

Start by ensuring your painted model is fully dry. Apply your chosen sealer in thin, even layers—using a soft brush helps distribute the coating smoothly. Allow sufficient time for curing, especially with epoxy options; “3D Finish” cures in about four hours at room temperature. After curing, the surface can be further polished if desired for extra gloss.

When This Matters Most

Sealing is particularly important for models that will be handled, displayed in direct light, or exposed to dust. A quality finish not only brings out vibrant colours but keeps your hard work protected for years to come.
