How to Apply Polyurethane to Veneer

Polyurethane is a broad term that refers to a number of acrylic clear finishes that can be used on wood and other surfaces. Veneer is a thin layer of hardwood grain that is used to cover another lesser wood to create the look of solid hardwood. Polyurethane can be applied to veneer in the same way it is applied to solid hardwood. Polyurethane is available in clear or in stain and poly combinations. If you are planning to stain your veneer, you can skip a step and apply stain and polyurethane all-in-one.

150-grit sandpaper
Polyurethane
Paintbrush (medium width, soft-bristled)
Emery cloth
Tack cloth

Instructions

- 1
  Sand the veneer with 100-grit sandpaper on a random orbit sander. This pass smooths any visible roughness in the grain. Do not oversand with the 100-grit sandpaper. Smooth the edges and work in the direction of the grain. Make a second pass with 150-grit sandpaper, working in the direction of the grain, to align the grain so it will accept the stain evenly. Rub the surface with a tack cloth to remove the dust.

  Apply two coats of polyurethane. Use a medium width soft-bristled brush and work in the direction of the grain. Spread the finish as smoothly as possible, working in slow even strokes to prevent drips and runs. Work slowly and avoid quick stops and starts, which cause bubbles in the finish. Allow the first coat to dry for at least three hours before applying the second coat. If you used stain and poly all-in-one for the first coat, use clear polyurethane for any subsequent coats. Apply the second coat in the same manner as the first and allow it to dry for three hours.

  Lightly sand the surface by hand with an emery cloth to smooth the finish. Rub the dust off with the tack cloth. Apply a third coat of polyurethane to give the veneer a deeper shine.
