Can You Apply Edge Banding Over Existing Edge Banding?28

Edge banding is an essential component of furniture manufacturing, providing a durable and aesthetically pleasing finish to the edges of panels and substrates. It protects the exposed core material from moisture, dirt, and damage, and can enhance the overall appearance of the furniture. While edge banding is typically applied to raw edges, there may be instances where you need to apply it over existing edge banding. This article will explore the feasibility and implications of applying edge banding over existing edge banding, providing insights into the process, considerations, and potential benefits and drawbacks.

Feasibility of Applying Edge Banding Over Existing Edge Banding

Applying edge banding over existing edge banding is generally feasible, but it requires careful preparation and execution. The success of the process depends on several factors, including:
Type of existing edge banding: The type of existing edge banding used will impact its adhesion to the new edge banding. PVC and ABS edge banding, which are commonly used in furniture making, are generally compatible with overbanding. However, veneer or wood edge banding may not bond as effectively.
Condition of existing edge banding: The condition of the existing edge banding should be assessed before overbanding. Loose, cracked, or damaged edge banding may need to be removed or repaired before applying new edge banding.
Edge profile: The edge profile of the existing edge banding should be considered. If the profile is too complex or intricate, it may be difficult to achieve a seamless bond with the new edge banding.

Considerations for Applying Edge Banding Over Existing Edge Banding

When applying edge banding over existing edge banding, several considerations should be taken into account to ensure a successful and durable result:
Surface preparation: The surface of the existing edge banding should be cleaned and sanded to remove any dirt, grease, or contaminants that may affect adhesion.
Adhesive selection: A suitable adhesive should be chosen based on the type of edge banding and the existing surface. Contact adhesives or hot melt adhesives are commonly used for overbanding applications.
Application technique: The new edge banding should be carefully applied over the existing edge banding, ensuring a tight bond. A roller or press can be used to create a strong adhesive bond.
Trimming and finishing: Once the new edge banding is applied, it should be trimmed and finished to create a seamless and professional appearance.

Benefits and Drawbacks of Applying Edge Banding Over Existing Edge Banding

Applying edge banding over existing edge banding can offer several potential benefits:
Improved durability: Applying a second layer of edge banding can further enhance the durability and longevity of the edges, providing additional protection against moisture and damage.
Enhanced appearance: Overbanding can be used to change the color or texture of the edges, allowing for design versatility and customization.
Repair and restoration: Overbanding can be used to repair damaged or worn edge banding, restoring the aesthetic appeal and functionality of the furniture.

However, there are also some potential drawbacks to consider:
Increased thickness: Applying multiple layers of edge banding can result in increased edge thickness, which may not be desirable in certain applications.
Bonding issues: If the existing edge banding is not properly prepared or if the adhesive is not suitable, bonding issues may occur, leading to peeling or delamination.
Complexity of application: Overbanding requires careful preparation and execution to achieve a successful result. It may be more challenging than applying edge banding to a raw edge.

Conclusion

Applying edge banding over existing edge banding is a viable option that can enhance the durability and appearance of furniture. However, it should be approached with care and consideration, taking into account the preparation, execution, and potential benefits and drawbacks. By following the guidelines and recommendations outlined in this article, furniture manufacturers and craftsmen can achieve successful overbanding results, extending the life and beauty of their furniture creations.
