Wood glue is a type of adhesive specifically designed for bonding wooden surfaces. It works by penetrating the wood fibers and creating a strong bond as it dries. Commonly used in woodworking, furniture making, and crafts, wood glue is available in various formulations, including PVA (polyvinyl acetate) and polyurethane, each offering different drying times and water resistance. When using wood glue, it's important to apply it evenly and clamp the pieces together until it sets. Most wood glues dry clear, making them ideal for visible joints. Proper storage and application can enhance the effectiveness and longevity of the bond.
