Fill and Sand Risers

What happens in this clip

After installing the plywood risers, fill any visible nail holes and small gaps or imperfections with wood filler. Allow the wood filler to dry completely according to the manufacturer's instructions. Once dry, use a sander (either manual or orbital) to smooth the filled areas and the entire surface of the risers, creating a uniform and paint-ready finish.

Goal: Smooth and prepare the installed plywood risers for painting.

About the full video

This project transforms an old carpeted staircase into a modern, illuminated hardwood staircase. The process involves removing old carpet, fabricating and installing new plywood risers and ash hardwood treads, integrating LED strip lighting, and finishing all components for a durable and aesthetically pleasing result.

Step 10 of 11: Sand Repaired Areas and Final Surface

Once the wood filler is completely dry, use a sanding block or fine-grit sandpaper (220 grit) to gently sand down the filled areas until they are flush with the surrounding wood. Then, lightly sand the entire surface of all treads and risers to ensure a uniform smoothness. Remove all sanding dust thoroughly with a vacuum and tack cloth.
