Few things are more frustrating for crafters than bubbles spoiling the surface of a newly made resin pot. With the right approach, you can significantly reduce bubbles and achieve a clearer, smoother finish in your creative projects.
Slow and Gentle Mixing for Fewer Bubbles
The key to minimising bubbles begins when you mix your resin. Stir the resin and hardener together slowly, making gentle, deliberate movements. Fast or aggressive mixing can trap extra air. Use spatulas or mixing sticks provided in kits like the “Vase” Flower Vase Resin Art Kit for greater control and less agitation.
Techniques for Releasing Trapped Bubbles
After pouring resin into your pot mould, gently tap or flex the mould to encourage air bubbles to rise to the surface and pop. If you find stubborn bubbles, you can lightly pass a heat gun or even a hair dryer above the resin’s surface for a few seconds. This helps small bubbles escape before the resin starts to cure. Allowing the resin to rest for several minutes after pouring can also make a difference, especially with deeper moulds.
When This Matters Most
Reducing bubbles is particularly important for projects where clarity and a flawless surface are desired. Decorative pieces, such as vases, trays or flower pots made using silicone moulds and coloured pigments, benefit greatly from careful bubble removal steps.
