How to Prevent Bubbles Under Phrases in Resin

Bubbles forming under embedded phrases in resin can cloud your finished piece. With the right preparation and pouring methods, you can greatly reduce unwanted bubbles and achieve crisp, professional results.

Preparing Your Phrase for Embedding

Before adding resin, it’s essential to ensure your printed or handwritten phrase lies perfectly flat and is well sealed. If using paper, lightly coat both sides with a clear-drying sealer or glue. This prevents any trapped air or ink bleed when resin is poured. Once dried and trimmed, press the phrase smoothly onto your mould or base so there are no raised areas where bubbles could hide.

Pouring Resin to Minimise Bubbles

When your phrase is ready, pour your resin slowly and steadily along the side of the mould, letting it gently flow over the embedded text. This careful pouring helps avoid air pockets forming underneath. For best results, consider a clear, beginner-friendly resin like the One-2-One Epoxy Resin, which mixes easily and self-levels for a flawless finish.

Final Bubble Removal Techniques

Once poured, inspect your project for visible surface bubbles. Use a pin or toothpick to carefully pop any bubbles floating up from below. For larger pieces, gently wave a heat gun or torch held at a safe distance across the surface to help release trapped air. Allow the resin to settle for a few minutes and repeat if needed before the curing process begins.
