What happens in this clip
Once all treads are cut to shape, thoroughly sand each piece. Start with a coarser grit sandpaper (e.g., 80 or 100 grit) to remove any saw marks or imperfections, then progressively move to finer grits (e.g., 120, 150, 180, and finally 220 grit) to achieve a smooth, ready-for-finish surface. Pay special attention to the edges and corners, slightly easing them to prevent splintering. After sanding, thoroughly clean the treads to remove all dust particles. Apply a high-quality wood finish that is suitable for high-traffic areas, such as a durable polyurethane, epoxy, or a hardwax oil. Apply multiple coats as recommended by the product manufacturer, allowing adequate drying time between coats and light sanding with a very fine grit (e.g., 320 grit) between some coats for optimal adhesion and smoothness. This step enhances the beauty of the reclaimed wood grain and protects it from wear and moisture.
Goal: Prepare the surfaces of the cut reclaimed wood treads by sanding them smooth and applying a durable protective finish.

About the full video
This analysis outlines the hypothetical steps to transform salvaged wood into unique treads for a spiral staircase, inspired by various staircase designs showcased in the video. While the video itself is a montage of finished products and not an instructional guide on creation, this project focuses on incorporating reclaimed wood for sustainable and characterful stair elements, aligning with the 'Woodworking > Reclaimed Wood & Upcycling' context.
Step 5 of 6: Sand and Finish Treads and Handrails
Using sandpaper of progressively finer grits, sand all exposed wood surfaces, including treads, risers, and handrails, until they are smooth to the touch. Wipe away all dust with a tack cloth or damp cloth. Apply your chosen finish according to the manufacturer's instructions. This may involve multiple coats of primer, paint, stain, or polyurethane. Allow adequate drying time between coats and light sanding if recommended. Ensure proper ventilation during this process.
