What should be done to prevent a plywood patch and the pressure plate from sticking together if glue is extruded from the joint?

• A. Heat the joint to set the glue faster.
• B. Place a piece of waxed paper or vinyl plastic between the patch and the pressure plate.
• C. Apply release tape to the patch and plate.
• D. Wipe the joint with oil to prevent sticking.

Answer: (B)

When glue squeezes out of a joint, it can bond the patch to the pressure plate as it cures. Using a nonstick barrier between the two surfaces stops that unintended adhesion. A thin sheet of waxed paper or vinyl plastic provides that barrier, allowing the patch to be clamped and the glue to cure without sticking to the plate. After curing, you can remove both the barrier and the patch cleanly. Heating would speed the cure but doesn’t prevent bonding and can risk damage; oil would contaminate the glue and weaken the bond; release tape could work as a barrier but waxed paper or vinyl is the standard, reliable choice in this situation.
