What is the primary advantage of using wood glue in carpentry?

The primary advantage of using wood glue in carpentry is that it bonds pieces of wood securely together. Wood glue creates a chemical bond between the fibers of the wood, which can result in a joint that is as strong, if not stronger, than the wood itself. This method of adhesion is particularly useful in applications where structural integrity is essential, such as in furniture-making or building frames.

Using wood glue allows for even distribution of stress across the joint, which can enhance the overall durability of the assembly. Additionally, wood glue can penetrate the wood pores, providing a more permanent solution compared to mechanical fasteners like screws and nails, which can loosen over time with movement or changes in humidity.

While some types of wood glue can be waterproof, the primary reason for its use is the strength of the bond it creates. It does not typically facilitate easy disassembly, and while it might create strong joints, traditional methods like nails have their own strengths in certain applications that are also critical in carpentry.
