Resin Compatibility FAQ: Paint, Stamping & Paper Transfers

Resin Compatibility FAQ

Quick answers to the questions we hear most from resin crafters — covering paint adhesion, stamping, and embedding paper or image transfers.

Can I paint on cured resin? Do I need to sand it first?

Yes, you can paint your cured resin castings with Rethunk Junk Paint by Laura. This is the paint we use and sell at Two Girls Treasure. In our tested experience with our resin castings, sanding is not necessary when using Rethunk Junk Paint.

Allow the resin to cure fully according to its product instructions before painting. Make sure the casting is clean and dry, then apply the paint according to Rethunk Junk's instructions.

Shop the Rethunk Junk Paint by Laura collection to choose your color.

Can I stamp onto a painted resin casting?

Yes! We recommend Iron Orchid Designs (IOD) Inks, the inks we exclusively carry at Two Girls Treasure. IOD inks are archival and work well over painted resin castings in our crafting experience.

Allow your resin to cure fully and your Rethunk Junk Paint to dry according to the product instructions before stamping. Let the ink dry completely before handling or applying a finish, following IOD's ink instructions.

This recommendation is for painted resin castings, not bare, glossy resin or mixing ink into uncured resin. Try your design on a sample first when using a new combination of materials.

Do I need to seal paper or image transfers before casting resin over them?

For paper inclusions, we recommend Rethunk Gunk decoupage medium, which we use and sell at Two Girls Treasure. Our recommendation is based on our tested crafting experience. Sealing paper helps protect it from absorbing resin and changing appearance.

1. Seal the paper's front, back, and edges with Rethunk Gunk decoupage medium, following its product instructions.
2. Allow the medium to dry completely before casting. Follow the product's drying instructions rather than a fixed waiting time.
3. Check for unsealed areas, especially on thin or absorbent paper, and apply additional coverage as needed.
4. Try a small sample with your chosen paper, ink, and resin before casting your finished project.

Paper images and rub-on transfers are different materials. For transfers, follow the transfer manufacturer's preparation and sealing instructions; our tested recommendation should not be taken as a guarantee for every transfer or ink.

Follow the instructions supplied with your specific Alumilite resin for preparing inclusions and curing. Our paper-sealing recommendation above is based on our studio experience.

Should I use mould release spray with silicone moulds?

Yes. Alumilite now recommends using mould release spray with any silicone mould to help prolong the life of the mould and make releasing the casting easier. We carry Alumilite Amazing Mold Release. Follow the release spray's application instructions and the instructions for your specific resin and mould.

Browse our Iron Orchid Designs Moulds collection for your next project. Follow the instructions for your chosen mould and resin, and try a small test pour when using a new combination.
