If the over-sanded areas of the veneer are too extensive to be filled with wood filler, you may need to patch them with new veneer pieces. Start by carefully removing the damaged veneer using a sharp utility knife or chisel, taking care not to damage the underlying substrate. Once the damaged veneer has been removed, cut a new piece of veneer to fit the area using a sharp utility knife or veneer saw.

Apply a thin layer of wood glue to the back of the new veneer piece and carefully press it into place, making sure to align the grain and pattern with the surrounding veneer. Once the glue has dried, sand the patched area to smooth out any imperfections and blend it with the rest of the surface.

3.Veneer Edge Banding:

If the edges of the veneer have been over-sanded, leaving them thin or uneven, you can use veneer edge banding to reinforce and repair them. Veneer edge banding is a thin strip of veneer with adhesive backing that can be applied to the edges of the veneer to provide additional strength and thickness.

Start by cutting a piece of edge banding to fit the length of the damaged edge using a sharp utility knife or veneer saw. Peel off the backing and carefully apply the edge banding to the damaged edge, pressing it firmly in place to ensure good adhesion. Once the edge banding is applied, use a veneer roller or block to smooth out any air bubbles and ensure a tight bond. Finally, trim any excess edge banding using a sharp utility knife or veneer trimmer, and sand the repaired edge to blend it with the rest of the surface.

4.Epoxy Resin Filling:

For larger gaps or voids in the veneer caused by over-sanding, epoxy resin can be used to fill and reinforce the damaged areas. Epoxy resin is a durable and versatile material that can be tinted to match the color of the surrounding wood. Start by mixing the epoxy resin according to the manufacturer’s instructions, adding any desired colorants or dyes to achieve the desired shade.

Carefully pour the mixed resin into the damaged areas of the veneer, taking care not to overfill. Use a plastic scraper or putty knife to spread the resin evenly and smooth out any air bubbles. Once the resin has cured, sand the repaired areas to smooth out any rough spots and blend them with the surrounding wood.

5.Applying New Veneer Layers:

If the over-sanded veneer cannot be repaired using filler or patching, you may need to apply new layers of veneer to the surface to restore its appearance. Start by sanding down the damaged veneer to create a smooth and even surface for the new layers to adhere to. Then, cut new veneer sheets to fit the affected areas using a sharp utility knife or veneer saw.

Apply a thin layer of wood glue to the back of the new veneer sheets and carefully press them into place, making sure to align the grain and pattern with the surrounding veneer. Once the glue has dried, sand the repaired areas to blend them with the rest of the surface and apply a finish or topcoat to protect the wood.

6.Staining and Refinishing:

If the over-sanded veneer has caused the wood to lose its color or finish, you may need to restain and refinish the surface to restore its appearance. Start by sanding down the damaged veneer to remove any remaining finish or stain and create a smooth surface for the new finish to adhere to.

Then, choose a stain color that matches the original shade of the wood and apply it evenly to the surface using a brush or cloth. Allow the stain to penetrate the wood for the recommended amount of time, then wipe away any excess with a clean cloth. Once the stain has dried, apply a clear topcoat or finish to protect the wood and enhance its appearance.

7.Using Wood Putty:

Wood putty can be used to fill in small cracks, holes, or gouges in over-sanded veneer. Start by selecting a wood putty that matches the color of the veneer as closely as possible. Apply a small amount of putty to the damaged area using a putty knife, pressing it firmly into any cracks or holes.
