Applying edge banding is a common woodworking technique used to finish the exposed edges of plywood, particleboard, or MDF, giving them a clean, finished look. It's especially popular for shelves, cabinet parts, and desks. One common type is iron-on edge banding, which has pre-applied hot-melt glue.
Steps for Applying Iron-On Edge Banding
Applying iron-on edge banding typically involves a few key steps to ensure strong adhesion and a smooth finish.
1. Prepare the Edge
- Ensure the edge of the material is clean, smooth, and free from dust or debris.
- Cut the edge banding slightly longer than the edge you plan to cover.
2. Position the Edge Banding
- Place the edge banding strip on the edge of the material, making sure it's aligned correctly.
- Leave a little overhang on both ends.
3. Heat and Apply
- Use a standard household iron set to a medium-high heat setting (check the banding manufacturer's recommendation).
- Slowly move the iron along the edge banding strip. The heat from the iron melts the glue on the back of the banding, bonding it to the wood substrate.
- Apply steady pressure as you move the iron, ensuring the entire width of the banding heats evenly.
4. Ensure Adhesion
Immediately after heating a section with the iron, use a wooden block, roller, or even just your hand (carefully, as it might be warm) to apply firm, even pressure along the just-heated section.
- As noted in the reference, you don't need to apply excessive pressure initially with the iron itself. The focus immediately after heating is to ensure the melted glue makes good contact with the edge.
- "I don't apply a lot of pressure. But I'm just kind of going down and ensuring that right on that edge on getting good adhesion of that glue. And then I do the same thing on the other. Side." This describes the crucial step of pressing the hot banding onto the edge right after heating to maximize the bond on both faces of the substrate's edge.
5. Trim Excess
- Once the glue has cooled and set (usually just a few minutes), use a sharp utility knife or a specialized edge banding trimmer to carefully remove the excess banding from the sides and ends. Hold the blade at a slight angle to avoid damaging the substrate surface.
6. Finish the Edges
- Gently sand the trimmed edges with fine-grit sandpaper (e.g., 150-220 grit) to smooth them flush with the substrate surface and remove any sharp corners.
- Wipe away any dust. The edge is now ready for finishing like painting or varnishing.
Following these steps helps create a durable and clean-looking edge on your woodworking projects.
