How do I prevent bubbles in resin with flowers?

Bubbles can spoil the clarity of resin and flower rings, distracting from the delicate beauty of embedded blooms. With the right preparation, you can achieve consistently smooth, clear results.

Seal Flowers Before Casting

One of the main reasons bubbles cling to dried flowers is that their surfaces are slightly porous, trapping air which later escapes into the resin. To avoid this, use a small brush to apply a thin layer of resin over each dried flower, effectively sealing tiny gaps. Allow this layer to cure before adding the main resin pour. This technique helps prevent air from escaping and forming bubbles around the petals and stems.

Pour Resin Slowly and Carefully

Pace is crucial during the main pour. Tilt your mould and pour the resin slowly, letting it flow gently around the flowers. This not only helps dislodge any air sitting in the mould but also reduces the risk of trapping bubbles under or beside delicate petals. If your resin, such as the Evershine Collection Epoxy Resin, is formulated for enhanced degassing, it can further support bubble-free casts when embedding detailed elements like florals.
