How do I remove bubbles from resin countertops?

Preventing and Removing Surface Bubbles

The main methods for dealing with bubbles in resin countertops are using a heat gun or applying isopropyl alcohol as a fine mist. As resin is poured and spread, gently running a heat gun across the surface encourages trapped air to rise and pop, leaving a flawless effect. Alternatively, a light spritz of isopropyl alcohol helps break surface tension, enabling bubbles to escape easily. Take care to hold the heat gun or spray bottle several inches away from the surface, moving quickly and evenly to avoid overheating the resin.

Tips for a Smooth Resin Finish

• Ensure your workspace and resin components are at room temperature before pouring to minimise bubble formation.
• After mixing the resin, let it sit for a few minutes so any larger air bubbles can naturally float to the top before pouring.
• Pour resin in thin, even layers as thick pours are more prone to trapping air.
• Make use of high-quality resin kits, like the “Stone Effect Collection” Epoxy Resin Countertop Kit, which includes isopropyl alcohol for enhanced bubble removal and realistic effects.

When Bubble Removal Matters Most

Bubbles are most visible—and most disruptive—on clear or light-coloured countertop finishes, especially when striving for a marble or high-gloss effect. It’s especially important to address bubbles promptly if your surface will be in a frequently used area, such as a kitchen or bathroom, where a smooth and hygienic finish is essential.
