Trapped bubbles are a common frustration when encapsulating wood in clear epoxy resin like “Trasparente”. With the right preparation and technique, you can achieve a brilliantly clear finish that showcases the natural beauty of wood.
Preparing Wood to Minimise Bubbles
Bubbles often arise due to moisture escaping the wood or air trapped in the grain. Ensure your wood is thoroughly dried—ideally, aim for a moisture content below 12%. Sand all surfaces well and remove dust with a clean, dry cloth. If the wood has open pores or end grain, consider pre-sealing it with a thin coat of suitable resin, such as EpoxyWood, which helps reduce air release during casting. Always work in a clean, dust-free space for the best results.
Layering Techniques for Clear Results
When using “Trasparente”, keep resin pours to layers of up to 2 cm. Thicker single pours can trap air and may overheat, leading to bubble formation. Pour slowly and in increments, allowing each layer to partially set before adding more. If bubbles do appear on the surface, gently remove them using a heat gun or a fine torch, taking care not to scorch the resin.
When This Matters Most
Bubbles are especially problematic in projects with highly figured wood, deep cracks, or when absolute clarity is essential—such as artistic pieces or tabletops. Taking extra care with preparation and pouring makes all the difference where a flawless, glass-like surface is the goal.
