Can You Paint Resin Miniatures After Curing?

Painting cured resin miniatures unlocks vibrant detail and personalisation in your models, whether you cast them yourself or purchase pre-made blanks. A simple preparation routine ensures the paint adheres well, resulting in a smooth and lasting finish.

Preparing Resin Miniatures for Painting

Once your miniature has cured completely (timing varies by resin type), surface preparation is the key to excellent paint adhesion. A light sanding with fine-grit sandpaper helps create a slightly rough texture, allowing both primer and paint to grip the surface. After sanding, remove any dust or debris by washing gently with soapy water and letting it dry thoroughly.

Ensure all residues are removed before priming

Best Paints and Priming Tips

A quality primer is essential for painting resin miniatures—standard hobby primers or spray-on acrylic primers work well. Priming prevents the paint from beading or flaking off, and helps colours look even. For your colour layers, acrylic paints are a popular choice, providing good coverage and flexibility over cured resin.

Apply primer in thin, even coats
Let each paint layer dry thoroughly before adding another

If you’re casting your own miniatures with products like IWhite polyurethane resin, the same preparation and painting steps apply.

When This Matters

Proper priming and painting techniques become especially important for detailed miniatures, gaming figures, or decorative collectibles where durability and fine finish are desired. Whether using UV, epoxy, or polyurethane resin, this approach brings out the best in your creations.
