Bubbles in resin artwork can disrupt the smooth, glassy finish that many creators are after. With a bit of technique and preparation, you can greatly reduce the risk of trapped air spoiling your finished piece.

Why Do Bubbles Form in Resin?

Bubbles usually appear when air is incorporated during the initial mixing of resin and hardener. Pouring too quickly or agitating the mix can also trap additional air, which is then carried into your mould or onto your surface. Being aware of how and when bubbles appear is the first step to preventing them.
