How Long Must Wood Dry Before Epoxy Resin Application?

Q: Best Practices for Drying and Preparing Wood

Acclimatise indoors: Store the wood in the room where it will be used to ensure it matches the environment. Check moisture regularly: Measure at different points for an accurate reading before application. Sand and clean: Ensure the surface is smooth, dust-free, and ready for resin to penetrate and bond. Seal if necessary: For older or especially porous wood, consider a deep-penetrating sealer like EpoxyWood before your main resin pour.

Before applying resin to wood, it’s essential that the timber is properly dried. Excess moisture can cause issues with resin bonding and overall durability, so getting this step right is crucial for the success of any wood and resin project.

How Dry Should Wood Be Before Resin?

To ensure a strong bond between wood and resin, the wood’s moisture content should be below 12%. Wood that is too damp can cause the resin to lose adhesion, leading to bubbling, cracking, or peeling over time. Use a moisture meter to check the content—especially if you’ve recently cut, purchased, or restored the timber. Ideally, allow wood to acclimatise in a stable indoor environment for at least two weeks, but drying times can vary depending on timber thickness and local conditions.

When This Matters Most

Proper drying is particularly important for thick, freshly sawn, or reclaimed wood used in tabletops, river tables, and outdoor projects. Neglecting this step risks both the look and longevity of your piece.
