How long should wood dry before resin?

Recommended Drying Time for Wood

Wood should ideally be left to dry for at least 24–48 hours in a low-humidity environment prior to resin application. This allows any surface or absorbed moisture to evaporate, reducing the risk of bubbles or cloudiness once the resin is poured. For thicker wood or projects where the wood was recently cut, longer drying periods may be beneficial.

Tips for Preparing Wood Before Resin

• Keep wood away from damp environments or direct sources of moisture.
• Check the wood’s surface temperature and moisture with a meter, if possible, aiming for dry-to-the-touch finishes.
• Sand the wood for better resin adhesion, especially if using products such as EpoxyWood for sealing or restoring exterior timber.
• Brush off dust and debris, ensuring the surface is both clean and dry prior to pouring resin.

When Moisture Control Is Crucial

Controlling moisture is particularly important for thick resin coatings, projects involving embedded objects, or when working with porous timbers. In these situations, even minor trapped moisture can cause discoloration, air pockets, or detachment over time.
