What type glue is typically used for edge to edge gluing of boards?

For edge-to-edge gluing of boards in woodworking, where a strong and durable bond is required, woodworkers often use woodworking glue specifically designed for this purpose. The most common and recommended type of glue for edge-to-edge bonding of boards is PVA glue (Polyvinyl Acetate). PVA glue is available in different formulations, including standard Wood Glue and more advanced versions. Here are some characteristics of PVA glue for edge-to-edge gluing:

Strong Bond: PVA glue creates a strong bond between wood surfaces, ensuring a durable connection.

Versatility: PVA glue is versatile and suitable for a variety of woodworking projects, including edge-to-edge gluing.

Easy Cleanup: PVA glue is water-based, making it easy to clean up with water before it dries.

Short Clamp Time: Many PVA glues have a relatively short clamp time, allowing for efficient assembly.

Dries Clear: PVA glue dries clear, leaving a clean and inconspicuous joint.

When using PVA glue for edge-to-edge gluing, it's important to follow best practices:

Prepare Surfaces: Ensure that the surfaces to be glued are clean, flat, and free from debris.

Even Application: Apply an even layer of glue on both mating surfaces.

Clamping: Apply sufficient pressure using clamps to ensure a tight bond. Follow the recommended clamp time specified by the glue manufacturer.

Excess Glue Removal: Wipe off any excess glue with a damp cloth before it dries.

Allow Sufficient Drying Time: Allow the glued joint to dry completely before subjecting it to stress or load.

It's worth noting that while PVA glue is widely used for edge-to-edge gluing, other specialized woodworking glues, such as polyurethane glue or epoxy, may be used depending on the specific requirements of the project. Always follow the recommendations provided by the glue manufacturer for the best results.
