What Kind of Glue Do Furniture Makers Use
Furniture makers use various types of glue, including hide glue, marine grade epoxy resin glue, aliphatic resin glue (yellow woodworkers glue), and polyurethane adhesives (like Gorilla Glue).
Hide glue, made from the hides of horses and cattle, offers great bonding strength and durability and is often used for valuable antiques.
Marine grade epoxy resin glue is strong and long-lasting, while aliphatic resin glue is less expensive and potentially reversible.
Polyurethane adhesives are also strong but require tightly fitting joints.
Surface preparation, clamping, and proper application of glue are important for solid joints, and excess glue should be cleaned up before it dries.
While modern furniture may rely more on pin nails or screws, glue is still preferred for well-designed, tightly fitting, and well-glued joints.
Did You Know?
1. Contrary to popular belief, furniture makers typically use a specialized adhesive known as “polyvinyl acetate” or PVA glue. This type of glue is known for its high strength and flexibility, making it ideal for bonding different types of wood together.
2. PVA glue, commonly referred to as “wood glue,” actually dries to a transparent finish, making it an excellent choice for furniture makers who want their craftsmanship to showcase the natural beauty of the wood.
3. One little-known secret among furniture makers is that they often use a technique called “blind joints” to join furniture pieces seamlessly without the use of visible fasteners or nails. This technique involves applying PVA glue into carefully crafted mortise and tenon joints, which provides both strength and aesthetics.
4. Another interesting trivia is that furniture makers sometimes use a separate type of glue called “cyanoacrylate” or CA glue for bonding delicate or small wooden pieces. CA glue sets rapidly, allowing furniture makers to save time in the assembly process and achieve a strong bond quickly.
5. In addition to wood, furniture makers may also use PVA glue to adhere other materials such as fabric, leather, or even metal accents to their creations. This versatile adhesive ensures that different components are securely attached together, contributing to the durability and longevity of the furniture.

Importance Of Surface Preparation And Joint Clamping
Regardless of the type of glue used, surface preparation plays a critical role in achieving a strong and durable bond. Furniture makers must ensure that the mating surfaces are clean and free from debris before applying glue. This can be done through sanding, planing, or scraping, depending on the specific project.
Once the surfaces are prepared, glue should be applied to all mating surfaces, with particular attention to end grain. This helps prevent glue-starvation, ensuring a solid bond. Clamping is then necessary to hold the parts together while the glue sets. However, over-tightening should be avoided to prevent over-squeezing of glue, which can weaken the joint. Special jigs and clamping blocks are often used to ensure correct angles and prevent damage to wood surfaces during the clamping process.
In modern furniture construction, glue is not the sole means of holding joints together. Pin nails or screws are often used in conjunction with glue to reinforce joints. However, it is important to note that supportive elements like nails, screws, and angle brackets should not be relied upon as the primary method of joint construction. Well-designed, tightly fitting, and well-glued joints should be able to bear the load without additional assistance. The use of foreign elements in structural joints can weaken the wood over time and even lead to broken joints. Therefore, proper gluing techniques and joint construction play a vital role in the long-term durability of furniture pieces.
To summarize, furniture makers have a range of glue options available to them. Each type of glue has its own unique characteristics and considerations. Hide glue offers tradition and reversibility, marine grade epoxy resin glue provides durability and weather resistance, aliphatic resin glue is affordable and versatile, and polyurethane adhesives deliver exceptional strength.
