What are the best ways to glue wood together in carpentry?

Wood glue is an essential tool for carpenters, as it helps to create strong bonds between pieces of wood. However, with so many different types of wood glue available, it can be challenging to know which one to choose. In this expert guide, we'll explore the top five methods for gluing wood in carpentry.

1. PVA Glue

PVA glue, also known as white glue or school glue, is a popular choice for carpentry. It's easy to apply, dries clear, and forms a strong bond. PVA glue is best for indoor use and works well with porous woods like pine, cedar, and fir. It's not recommended for use on oily or dense woods like teak or rosewood.

2. Polyurethane Glue

Polyurethane glue, also known as Gorilla Glue, is a versatile adhesive that works well with both porous and non-porous woods. It expands as it dries, creating a strong bond. Polyurethane glue is waterproof and heat-resistant, making it an excellent choice for outdoor use.

3. Epoxy Glue

Epoxy glue is a two-part adhesive that's incredibly strong and durable. It works well with both porous and non-porous woods and can be sanded and painted once it's dry. Epoxy glue is waterproof and heat-resistant, making it an excellent choice for outdoor use.

4. Hide Glue

Hide glue, also known as animal glue, is a traditional adhesive that's made from animal collagen. It's best used for fine woodworking projects like furniture making, as it forms a strong bond that can be easily reversed with heat. Hide glue is not waterproof, so it's not recommended for outdoor use.

5. Cyanoacrylate Glue

Cyanoacrylate glue, also known as super glue, is a fast-drying adhesive that forms a strong bond between wood surfaces. It's best used for small woodworking projects and repairs, as it's not as strong as other types of wood glue. Cyanoacrylate glue is not waterproof, so it's not recommended for outdoor use.
