Understanding the Bottom Gap Defect

The bottom gap defect, also known as "hollow edge" or "edge curl," refers to the unsightly gap that forms between the edge banding strip and the substrate at the bottom edge of the furniture piece. This defect can arise due to various factors, including:
Inadequate adhesive application
Incorrect edge banding material selection
Improper edge banding process
Environmental factors (e.g., temperature, humidity)

Preventing the Bottom Gap Defect

To prevent the bottom gap defect, it is crucial to adhere to the following best practices:
Ensure Proper Adhesive Application: Apply an even layer of high-quality adhesive to both the edge banding strip and the substrate. Use an edge banding machine equipped with a glue spreader for precise application.
Select Suitable Edge Banding Material: Choose edge banding strips that are compatible with the substrate in terms of thickness, material, and expansion coefficient. Avoid using excessively thick or thin edge banding.
Follow the Correct Edge Banding Process: Ensure that the edge banding machine is calibrated properly and that the pressure, temperature, and feed rate are optimized for the specific edge banding material.
Control Environmental Factors: Maintain a stable temperature and humidity during the edge banding process and storage of edge banded furniture pieces.

Solutions for Fixing the Bottom Gap Defect

If the bottom gap defect has already occurred, there are several methods to resolve the issue:

1. Re-bonding with Hot Melt Adhesive

Apply hot melt adhesive to the bottom edge of the edge banding strip.
Press the edge banding strip firmly into place using a heat gun or a heated press.
Allow the adhesive to cool and cure completely.

2. Inserting a Filler Strip

Cut a thin strip of wood or plastic that is slightly thicker than the gap.
Apply a small amount of glue to the filler strip and insert it into the gap.
Trim the excess filler strip and sand it flush with the edge banding strip.

3. Using a Caulking or Filler Compound

Apply a bead of flexible caulking or filler compound to the gap.
Smooth the compound using a putty knife or a damp cloth.
Allow the compound to dry and paint or stain it to match the edge banding strip.
