Ensuring your wood has a moisture content between 8–12% before pouring resin isn’t just a tip—it’s a vital step. This guide explains why, and how to prepare timber for a durable, clear resin encapsulation.
Why Moisture Control Matters
Wood that contains too much moisture can release trapped water into the resin, leading to issues like cloudiness, bubbles, or poor adhesion. If the wood is too dry or too damp, movement can occur beneath the hardened resin, potentially resulting in warping or resin detachment over time. Keeping the moisture content within the 8–12% range provides the best balance for stability and successful encapsulation.
How to Prepare Wood for Resin Encapsulation
- Measure first: Use a reliable moisture meter to test the wood at multiple points for an accurate reading.
- Acclimatise timber: Store the wood in the same environment as your workspace for several days before beginning the resin work, ensuring it adjusts naturally.
- Optional sealing: For porous or reclaimed woods, applying a sealing coat with a product like EpoxyWood can reinforce fibres and help prevent moisture migration.
When This Matters Most
Keeping the moisture in check is especially crucial if you’re planning deep pours or working on large tables, as thicker resin layers amplify the risks of trapped moisture causing visible defects. For river tables or artwork, this step ensures a flawless, long-lasting finish.
