How to Use Bondo on Cabinet Edges Before Wrapping with Architectural Film

In this tutorial, we'll show you how to repair and prepare the edge of a cabinetry piece using Bondo before wrapping it with an architectural film. This method is especially useful when there's a chunk of wood missing, as Bondo can be shaped to form a clean corner and provides a hard surface for the film to adhere to.

Materials Needed

Bondo

Hardener (usually comes with the Bondo)

Putty knife

Sandpaper (various grits)

Clean cloth

Masking tape (optional)

Architectural film

Squeegee or application tool

Step-by-Step Instructions

Step 1: Prepare the Area

Clean the Surface: Ensure the edge of the cabinetry is clean and free of dust, dirt, and grease. Use a clean cloth to wipe the area.

Masking (Optional): If you want to protect the surrounding areas from Bondo, use masking tape around the edge where the repair will be made.

Step 2: Mix the Bondo

Read Instructions: Follow the manufacturer's instructions for mixing Bondo and hardener. Typically, you'll mix a small amount of hardener with the Bondo until you achieve a uniform color.

Mix Thoroughly: Use a putty knife to mix the Bondo and hardener on a clean, non-porous surface. Work quickly, as Bondo can start to harden within minutes.

Step 3: Apply the Bondo

Apply to the Edge: Using the putty knife, apply the mixed Bondo to the damaged edge of the cabinetry. Overfill slightly to ensure you have enough material to shape a clean corner.

Shape the Edge: While the Bondo is still pliable, shape it into a clean corner. You can use the putty knife to smooth and form the desired shape.

Step 4: Let it Cure

Allow to Dry: Let the Bondo cure completely. This typically takes about 20-30 minutes, but check the manufacturer's instructions for specific curing times.

Step 5: Sand the Surface

Sand Smooth: Once the Bondo is fully cured, use sandpaper to smooth the surface. Start with a coarser grit to remove excess material and then switch to a finer grit for a smooth finish.

Clean the Area: Wipe away any dust created during sanding with a clean cloth.

Step 6: Apply the Architectural Film

Prepare the Film: Measure and cut the architectural film to the appropriate size for the cabinetry edge.

Apply the Film: Starting from one end, carefully apply the film to the edge, using a squeegee or application tool to smooth out any bubbles or wrinkles. Make sure the film adheres well to the Bondo-repaired edge.

Finish the Edges: Trim any excess film and ensure all edges are securely adhered.

By following these steps, you can effectively repair and prepare cabinetry edges with Bondo before wrapping them with architectural film. This method ensures a smooth, clean corner that enhances the adhesion and appearance of the film.
