How to Set Up Table Base & Formwork for Resin Tables

← Back to How to make a wood, resin, and coin table?

The foundation of every successful wood and resin table build starts with a properly prepared base and formwork. Taking care at this stage ensures a professional finish and avoids leaks or warping when you pour your resin.

Selecting and Preparing the Table Base

Begin by choosing a sturdy and level platform for your project. Wooden table bases, like the Geode O Table Base, are well-suited for epoxy resin art, providing lasting durability and compatibility with a range of creative techniques. Sand the base lightly to remove rough spots and ensure the surface is clean and dust-free before assembling your mould.

Formwork Materials and Sealing

To shape your table, you’ll need to build a mould (formwork) slightly larger than your intended finished size. Melamine-coated boards are a popular choice, as they resist sticking. Apply a release tape or specialised film to the inner surfaces to make demoulding easier. For the edges, use a high-quality silicone sealant to prevent resin leaks—kits such as the River-Table Complete Kit often include silicone paste and clear instructions for optimal results.

Assembly and Practical Tips

Secure the boards tightly with screws or strong clamps, checking for gaps or uneven joins. Run a bead of silicone sealant along all inner seams and allow it to cure fully before pouring. If you’ll add coins or other objects, arrange them on your base beforehand so you can visualise the finished look. Take your time to ensure everything is level and sealed, as a well-built formwork makes the resin pour much easier.

When Careful Preparation Matters Most

Creating complex or deep resin designs that require strong leak prevention.
Embedding heavy items like coins and wood slabs that may shift during the pour.
Ensuring your table surface remains flat and the edges crisp once released from the mould.
