How to Patch Holes in Stair Railings

Holes in stair railing left from previously removed screws or nails can detract from the overall appearance of the stairway. Patch the holes with a simple two-part wood filler that consists of a putty and hardener. Wood filler can fill large and small holes and even be sculptured to repair larger chunks missing from wood. However, if the railing is severely damaged, consider replacing it. It is important to prepare the surface and allow the filler to harden before sanding and applying finish.

Things You'll Need

• 100-grit sanding pad
• Wood filler
• Putty knife
• 220-grit sanding pad
• Tack cloth
• Wood finish
• Paintbrush

Instructions

1. Sand the area surrounding the hole in the railing with a 100-grit sanding pad. Be sure to sand with the grain of the wood. This will remove the shiny finish and allow the putty to bond to the surface.

2. Mix the wood filler putty and hardener together with a putty knife on the inside of the lid.

3. Fill the hole with putty and smooth over the top surface of the hole using a putty knife. Allow the filler to harden for 15 to 20 minutes.

4. Sand the filler with a 220-grit sanding pad in the direction of the grain until it is a seamless transition from the repair to the rest of the railing.

5. Wipe off the dust left from sanding, using a tack cloth. Dab on a matching wood finish to the patched area with a paintbrush. Allow the finish to dry for 72 hours before heavy use.

Tips & Warnings

• If you have several holes to patch, mix small amounts of filler at a time since it begins to harden after approximately 5 minutes.

• Wear eye protection when sanding.
