What Glue to Use for Edgebanding?181

Edgebanding is a thin strip of material that is applied to the exposed edges of plywood, particleboard, or MDF. It serves several purposes, including protecting the core material from moisture and damage, enhancing the appearance of the piece, and providing a smooth and finished edge. The type of glue used for edgebanding is crucial for ensuring a strong and durable bond between the edgebanding and the core material.

There are several types of glue that can be used for edgebanding, each with its own advantages and disadvantages:
Hot melt glue: Hot melt glue is a thermoplastic adhesive that is applied in a molten state and then cools to form a strong bond. It is easy to apply and provides a quick bond, but it can be sensitive to temperature changes and may not be suitable for use in high-heat environments.
Contact adhesive: Contact adhesive is a type of adhesive that forms a bond when two surfaces are pressed together. It is easy to apply and provides a strong bond, but it can be difficult to reposition the edgebanding once it has been applied.
PVA glue: PVA glue, also known as wood glue, is a type of water-based adhesive that is easy to apply and provides a strong bond. It is not as heat-resistant as hot melt glue, but it is more resistant to moisture than contact adhesive.
Epoxy adhesive: Epoxy adhesive is a type of two-part adhesive that forms a very strong bond. It is more difficult to apply than other types of glue, but it is also more durable and resistant to heat and moisture.

The best type of glue for edgebanding depends on the specific application. For general use, PVA glue is a good choice because it is easy to apply, provides a strong bond, and is resistant to moisture. For high-heat applications, hot melt glue is a good choice. For applications where repositioning may be necessary, contact adhesive is a good choice. For the strongest and most durable bond, epoxy adhesive is a good choice.

In addition to the type of glue, it is also important to consider the following factors when choosing an edgebanding adhesive:
Open time: Open time is the amount of time that the glue remains tacky before it sets. This is important because it gives you time to position the edgebanding correctly before it bonds permanently.
Viscosity: Viscosity is the thickness of the glue. A thicker glue will provide a stronger bond, but it can be more difficult to apply. A thinner glue will be easier to apply, but it may not provide as strong a bond.
Coverage: Coverage is the amount of surface area that the glue can cover. This is important because it will determine how much glue you need to purchase.

By considering the factors discussed above, you can choose the right glue for your edgebanding application and ensure a strong and durable bond.
