Wood Glue Guide: Which Goes Where

Glue to use: Polyurethane. This adhesive sticks to wood, metal, and even old glue. When exposed to water, it expands as it cures, reducing the wiggle room in loose joints.

How-to tips: Wearing gloves, lightly dampen one side of the project, then add a thin layer of glue to the other side; clamp for up to 2 hours. Clean up spills with paint thinner.
