In Ghana, from the skilled carpenters in Kokompe and Anloga making beautiful furniture, to the boat builders in our coastal towns, and even for simple repairs in our homes, joining pieces of wood together is a fundamental skill. While nails and screws are common, the real secret to strong, seamless, and long-lasting wooden artefacts is the correct use of adhesives, or glue. Understanding the different types of adhesives and knowing when to use each one is crucial for any student of Applied Technology. This lesson will equip you with the knowledge to choose and use the right glue for any woodworking task, ensuring your projects are durable and professional.
2.1 What is an Adhesive?
An adhesive is a substance capable of holding materials together by surface attachment. In woodworking, we simply call it glue. It works by creating a bond between two surfaces. A good glue joint is often stronger than the wood itself. 2.2 Main Categories of Woodworking Adhesives
Woodworking adhesives are broadly divided into two main categories based on their origin: Protein Adhesives (Natural Adhesives): These are made from natural, organic sources, primarily animal or plant proteins. They have been used for centuries. Synthetic Resin Adhesives (Man-made Adhesives): These are created through chemical processes and are the most common type of adhesives used in the modern woodwork industry.
