Does It Make Sense to Glue Edge Banding on Top of Edge Banding?95

Edge banding acts as a protective and decorative element on the exposed sides of furniture components. It helps seal the edges of the material to prevent moisture damage, splitting and chipping, and enhance the overall aesthetics of furniture. The application of edge banding is a common practice in the woodworking industry.

In most cases, edge banding is applied once to the edge of a furniture component. However, there are instances where a manufacturer may decide to apply a second layer of edge banding on top of the first one. This practice is generally not recommended and should be avoided if possible due to several reasons.

Decreased Bonding Strength

When edge banding is glued to the substrate, it creates a strong bond that holds the two materials together. This bond is essential for ensuring that the edge banding remains in place and does not peel or delaminate over time. However, when a second layer of edge banding is applied on top of the first one, the bonding strength between the two layers is significantly reduced. This is because the adhesive used to bond the second layer of edge banding must adhere to the first layer of edge banding, which has a different surface texture and composition than the substrate. As a result, the bond between the two layers of edge banding is weaker and more prone to failure.

Increased Thickness

Each application of edge banding adds to the overall thickness of the furniture component. While a single layer of edge banding is typically thin enough to be inconspicuous, multiple layers of edge banding can create a noticeable increase in thickness. This can be a problem for furniture components that are designed to fit into specific spaces or have tight tolerances. Additionally, the increased thickness can make it more difficult to install hardware or other components on the furniture.

Difficulty in Sanding and Finishing

Sanding and finishing are essential steps in the manufacturing process of furniture. These processes help to smooth the surface of the furniture and prepare it for painting or staining. However, sanding and finishing can be more difficult when there are multiple layers of edge banding. This is because the different layers of edge banding may have different densities and hardness levels, which can make it difficult to achieve a consistent finish. Additionally, the adhesive used to bond the layers of edge banding can gum up sandpaper and make it less effective.

Increased Cost

Applying multiple layers of edge banding requires more materials, labor, and time. This can add to the overall cost of manufacturing the furniture. In most cases, the cost savings of using a single layer of edge banding outweigh the benefits of using multiple layers.

Alternatives to Gluing Edge Banding on Top of Edge Banding

If you are looking for a way to improve the strength or appearance of your furniture, there are several alternatives to gluing edge banding on top of edge banding. These alternatives include:
Using thicker edge banding
Using a different type of edge banding material
Applying a clear finish over the edge banding
Using a decorative trim or molding to cover the edge banding

Conclusion

While it may be tempting to glue edge banding on top of edge banding to improve the strength or appearance of your furniture, it is generally not recommended. This practice can lead to decreased bonding strength, increased thickness, difficulty in sanding and finishing, and increased cost. Instead, consider using one of the alternatives listed above to achieve the desired results.
