How should adhesive be applied to a wood joint?

Applying adhesive to both surfaces of a wood joint is essential for ensuring a strong bond. When adhesive is spread on both mating surfaces, it allows for a more uniform and effective coating, which can penetrate any small gaps or irregularities in the wood grain. This complete coverage leads to better adhesion and helps prevent issues such as delamination or weak points in the joint that could compromise the structural integrity over time. By ensuring that both surfaces are adequately coated, the adhesive can perform optimally, resulting in a secure and reliable connection in aviation-grade applications where safety is paramount.
