How Do I Keep Flower Colours Bright in Resin?

If you’ve ever embedded delicate blooms in resin only to watch their colour fade, you’re not alone. It is possible to preserve much of a flower’s vibrancy with a few careful preparations and the right resin techniques for your next project.

Seal Flowers Before Embedding

Fresh and dried flowers are both susceptible to colour changes when exposed to resin. The most reliable method to retain their hues is by applying a resin-compatible sealant first. Use a gentle spray or brush-on sealant to fully coat the flowers, allowing them to dry completely before embedding. This simple step helps prevent unwanted reactions between the natural pigments and the resin, ensuring your blooms maintain their charm.

For maximum ease, consider using Natural Dried Flowers for Art Projects and Epoxy Resin Casting, which are already prepped for resin work.

Resin Casting Tips for Brighter Colours

The resin pouring process itself can affect flower vibrancy. Avoid pouring too quickly, as this can trap air and agitate the flower petals. Instead, pour the resin in a slow, steady stream to prevent colour bleeding or fading. Work in layers if you’re embedding larger arrangements, letting each set gently before proceeding.

Limiting exposure to direct sunlight—especially before the resin fully cures—will also help reduce UV-related discolouration. It’s best to display or store finished resin pieces away from harsh light sources to preserve their brilliance.

When Colour Preservation Matters Most
