How to Fix Bubbles in a Resin Shower Tray

Q: Practical Methods for Removing Bubbles

During Pouring: Gently run a heat gun or use a small torch across the wet surface directly after pouring. The heat encourages bubbles to rise and burst but avoid excessive exposure to limit resin overheating. After Curing: If bubbles persist once set, sand the affected surface with a fine grit until smooth. For glossy results, apply a suitable finishing polish. Always mix resin slowly and thoroughly to reduce bubble formation from the start, and pour in a steady stream for best results.

What if there are bubbles in my resin shower tray?

Noticing bubbles in your resin shower tray can be disappointing, but with the right steps, you can fix or minimise these imperfections for a smooth result.

Why Bubbles Form in Resin Shower Trays

Bubbles often appear when mixing or pouring resin too quickly. Trapped air can rise and become sealed beneath the surface, especially in deeper pours or if the workspace is cool. Using a low-viscosity resin such as EpoxyTable 5-Five, designed for minimal bubbles, is a helpful first step.

When This Matters

Perfecting your tray surface is particularly important for areas with regular water exposure, where evenness helps prevent grime build-up and maintains a professional finish.
