Casting resin into a wood channel is a popular technique for river tables and unique wooden pieces. Choosing the right epoxy is essential for strong, clear and durable results, especially when working with deeper or wider channels.
Deep Pour Epoxy: The Ideal Choice
For wood channels—whether in live edge tables or creative inlays—specialised deep pour epoxy resins are the top choice. Products such as EpoxyTable 5-Five are specifically formulated for pours up to 5cm thick in a single layer. These resins have a low exothermic reaction, which helps prevent overheating and minimises bubbling during curing.
When casting into channels deeper than 5cm, opt for an ultra-deep pour resin like “Epoxytable 10-Ten”, ideal for projects up to 10cm thick. For shallower channels, beginners might find value in all-in-one kits that provide resin, hardener, and sealing materials, such as the “River-Table” complete kit.
Practical Pouring Tips
- Surface Prep: Ensure the wood is thoroughly dried and free of dust. Seal excessively porous wood with a thin coat of epoxy to prevent air bubbles.
- Pouring in Layers: For extra-thick pours or high-volume projects, pouring in several layers (with time between) helps control heat build-up and ensures clarity.
- Bubble Control: Deep pour resins are low in viscosity to reduce trapped air, but using a heat gun or torch gently over the surface can further eliminate bubbles as the resin settles.
When This Matters Most
Selecting the correct resin is most important for projects like river tables, large decorative trays, or any woodworking design where clarity and resin depth are essential. Using a product designed for deep casting ensures structural stability and an even, glossy finish.
