Fed up with bubbles ruining your resin projects? Don't panic—here are 3 common causes to help you avoid pitfalls! First, over-stirring. When mixing resin components A and B, rapid circular motions or vigorous stirring trap air into the liquid, creating dense clusters of tiny bubbles. Second, inadequate degassing. If you add small decorations like glitter or dried flowers directly into the resin without ensuring all air pockets are expelled, bubbles will appear after curing. Finally, low ambient temperature. Below 20°C, the resin's flowability decreases, slowing the rise of bubbles to the surface. They solidify before they can escape. Master these points, and your next resin project will be perfectly smooth!
