Which method is NOT commonly used to apply pressure to glue joints?

Applying pressure to glue joints is crucial for achieving a strong bond during the adhesive curing process. The method not commonly used for this purpose is powder coating, which is a finishing process used to apply a protective and decorative layer to surfaces rather than to bond materials together.

Nailing joints, clamping, and using brads are all methods employed to exert pressure on glue joints. Clamps are designed specifically to hold parts tightly together while the adhesive sets, ensuring that there is a consistent and even pressure across the joint. Nailing and using brads also provide mechanical fastening that holds the parts together while the glue cures, although these methods are more about holding pieces in place rather than applying even pressure throughout.

In summary, powder coating does not play a role in the application of pressure for adhesive bonding, while clamps, nailing, and brads are directly relevant to achieving strong glue joints.
