How to Fill a Crack in a Wood Veneer

Wood veneer is a thin piece of wood usually used to cover furniture. Since it is thin, it might crack after years of use or through an accident. With wood filler, a clamp and stain, you can make wood veneer look good as new again. Here's how.

Tools and Materials

  • Detergent
  • Sponge
  • Dry cloth
  • Paint stripper
  • 100-grit and 200-grit sandpaper
  • Solvent-based wood filler
  • Used makeup spatula
  • Toothpick
  • Clamp
  • Wood stain
  • Wood sealer or clear varnish
  • Paintbrush
  • Small painter’s brush

Step 1 – Prepare the Surface

Mix mild detergent and water. Dip the sponge, wring it and clean the surface of the wood veneer to remove dirt and oil. Make sure that the sponge is not dripping wet. Rinse the wood using a damp sponge. Immediately wipe the surface dry with a soft cloth.

Apply paint stripper to remove varnish, sealer or stain on the surface. Afterwards, sand the cracked area with 100-grit sandpaper. The surface is now prepped for filling.

This is also the best time to re-stain your wood veneer. If you have decided to do so, you may prep the entire surface by following the same procedure above.

Step 2 – Apply Filler

Buy solvent-based wood filler for its quick drying time and to prevent moisture (which water-based filler has) from getting absorbed by the wood. Fill the crack using a makeup spatula. For small cracks, you may use a toothpick to push the filler further down the crack.

Get the clamp, attach the rubber ends to protect the wood, and insert the clamp perpendicularly to the crack line. Twist the end of the clamp to keep it in place. Wipe the filler that overflows after clamping. Allow the filler to set.

Remove the clamp. Sand the cracked area again using a finer grit sandpaper this time. Level the area to the rest of the surface.

You can also fill holes and chippings using the wood filler.

Step 3 – Apply Stain

Wipe the surface with a dry cloth or brush it with a clean paintbrush to remove small particles or dust that form during sanding. If you have decided to work on the cracked area only, use a painter’s brush to stain the sanded area. Apply several thin coats.

To stain the entire surface, get the cotton cloth and dip it in the stain. Rub it on the wood veneer in a circular motion over the entire surface. Apply a thin coat. Allow it to dry before applying another coat. Coat again until the desired tone is achieved. Allow it to dry thoroughly before you seal.

Step 4 – Seal

You may use either a clear varnish or another type of wood sealer to seal the wood. A sealer protects the wood veneer’s surface from moisture and scratches. Buy the solvent type.

Get the paintbrush and apply the sealer on the surface. Your first coat should be thin. Let it dry and seep deeply into the wood’s pores. Apply another coat evenly but this time with a thicker coat. Allow to dry.
