Resin leaks are one of the most common challenges when crafting a wooden and resin table. Proper preparation of your table mould is key to a smooth and mess-free project.
Why Sealing the Mould Matters
Even small gaps or cracks in your formwork can allow epoxy resin to seep through, wasting precious material and affecting the final finish of your table. Leaks are much easier to prevent than to fix after a pour has started, so attention to detail at this stage is essential for anyone aiming for a professional result.
How to Properly Seal Your Table Mould
Begin by assembling your mould with well-fitted boards or panels. All joins should fit snugly. To seal the formwork, apply a continuous bead of silicone sealant along every internal corner and joint—this blocks even the smallest gaps. Allow the silicone to cure fully before pouring the resin. Alternatively, you can reinforce the base and seams with strong adhesive tape, ensuring it is firmly pressed into place. Both methods help stop leaks during the curing process.
- Inspect the mould for gaps before sealing
- Use quality silicone for a flexible, effective seal
- Test with a small amount of water if unsure of the seal
Practical Guidance for Beginners
If you are new to resin projects, a ready-made kit such as the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table includes both the resin and a special silicone paste designed for easy and reliable formwork sealing. Detailed instructions are provided to guide you step by step from preparing the mould to finishing your table.
When This Matters Most
Thorough sealing is especially important when working with deep pours or intricate mould shapes. Those using higher volumes of resin or creating ‘river’ tables should take extra care to double-check seals and allow adequate curing time for all materials used in the mould.
