Identifying the Problem

Before diving into fixing over sanded veneer, it’s essential to correctly identify the issue. Over sanding usually results in a thinner veneer surface and can cause unevenness. This will help you determine the extent of the repair needed.


Start by clearing the area and making sure it’s dust-free. Having a clean workspace will help you carry out the fix more effectively.

Step-by-Step Instructions

Here are the steps you’ll need to take…

Step 1: Assess the Damage

Tools Needed: Flashlight, Magnifying Glass, Measuring Tape

Initial Observation: Start by examining the damaged veneer under good lighting. Use a flashlight if necessary to highlight the imperfections.

Depth Measurement: Use a measuring tape to get an approximate idea of how deep the over sanding has penetrated the veneer. If possible, use a magnifying glass for a more precise look.

Material Assessment: Determine what the veneer is made of. Whether it’s hardwood or softwood will influence your next steps.

Damage Documentation: Take pictures of the damaged areas. This helps in case you need to consult with professionals or require evidence for insurance purposes.

Step 2: Apply Wood Filler

Safety First: Always wear safety glasses and gloves to protect yourself from splinters and chemicals.

Preparation: Clean the area to remove any dust or debris that might interfere with the wood filler’s adherence.

Application: Using a putty knife, carefully apply the wood filler into the deep grooves or holes caused by the over sanding.

Leveling: Make sure to level the filler with the surface of the veneer as much as possible for a seamless look.

Drying: Allow the filler to dry as per the directions provided on the product packaging. The drying time may vary depending on the brand and type of wood filler.

Step 3: Light Sanding

Tools Needed: Fine-grit Sandpaper (180 – 220 grit), Sanding Block or Electric Sander, Dust Mask

Safety Measures: Wear a dust mask to prevent inhalation of fine wood particles.

Select Sandpaper: Choose a fine-grit sandpaper, preferably within a 180-220 grit range, to avoid causing further damage.

Sanding: Using a sanding block or electric sander, lightly sand the area where the filler was applied. Make sure to move in the direction of the wood grain to maintain a consistent finish.

Smoothness Check: Frequently stop and feel the area to ensure it is becoming smooth.

Clean Up: Once you are satisfied with the smoothness, wipe down the area with a damp cloth to remove any remaining sanding dust.

Step 4: Staining

Tools Needed: Wood Stain, Brushes or Foam Applicators, Clean Cloth, Gloves, Safety Glasses

Safety Precautions: Wear gloves and safety glasses to protect your skin and eyes from potential irritants in the wood stain.

Choosing the Stain: It’s crucial to pick a stain that closely matches your existing veneer. Test the stain on a hidden section of the veneer to ensure it’s a good match.

Preparation: Make sure the area is clean and free of any sanding dust. This ensures better stain adhesion.

Application Method: Depending on your preference and the manufacturer’s recommendation, use a brush or foam applicator for application.

Stain Application: Using a clean cloth or your chosen applicator, apply the stain in the direction of the wood grain. Ensure the application is even to avoid blotchy areas.

Drying Time: Let the stain dry according to the product’s instructions. Always refer to the manufacturer’s guidelines, and consult authoritative sources for best practices on drying time and conditions.

Step 5: Apply Wood Glue

Tools Needed: Wood Glue, Clamps, Putty Knife or Spatula, Damp Cloth

Identifying Loose Areas: Inspect the veneer, particularly at the edges and corners, to find any areas that may have come loose or are not adequately bonded.

Safety Measures: Though wood glue is generally non-toxic, it’s still a good idea to wear gloves to keep your hands clean and avoid any possible skin irritation.

Glue Application: Using a putty knife or a spatula, carefully apply a thin layer of wood glue to the loose areas. Make sure not to over-apply, as excess glue can seep out and create a mess.

Bonding: Once the glue is applied, press the loose veneer firmly back into place.

Clamping: Use clamps to hold the veneer in place while the glue dries. Make sure the clamps are not too tight as to avoid warping or denting the veneer.
