How does the presence of natural resins in cedar affect adhesive bonding?
Cedar wood is prized for its durability and aromatic qualities, but its natural resins can complicate adhesive bonding. These resins, which protect the wood from decay and insects, create a hydrophobic surface that resists glue penetration. Common woodworking adhesives like PVA or epoxy may struggle to form strong bonds due to this resin barrier. To improve adhesion, surface preparation—such as sanding or solvent cleaning—is often necessary. Understanding this interaction helps woodworkers achieve stronger, longer-lasting joints in cedar projects.
