The strongest wood glue is generally considered to be polyurethane glue, specifically brands like Gorilla Glue. Polyurethane glues are known for their strong bonding capabilities, working well on various wood types, and even bonding to materials like metal, stone, and ceramics.
Here are some other highly recommended types of wood glue, each with unique advantages:
PVA (Polyvinyl Acetate) Glue: This includes Titebond III Ultimate Wood Glue and Elmers Wood Glue Max. These are strong, moisture-resistant, and perfect for indoor use. Titebond III is especially popular because it’s waterproof and offers a strong, durable bond.
Epoxy Resin: Epoxies like West System Epoxy are incredibly strong and durable, providing a tough bond that can withstand extreme conditions. They’re great for more specialized projects or when working with highly stressed joints.
Hide Glue: Traditional hide glue, often used in furniture restoration, has a strong bond but is less commonly used in modern woodworking because of its sensitivity to temperature and moisture.
For typical woodworking projects, Titebond III and Gorilla Glue are the top choices due to their ease of use and reliability in creating strong, lasting bonds.
Always consider your project needs, such as resistance to moisture, temperature, or flexibility, when choosing the right glue.
