Sand the Stairs

What happens in this clip

Once the old paint and varnish are removed, sand the entire surface of the stairs. Start with a rough grit sandpaper (e.g., 60 or 80 grit) using an orbital sander to remove any remaining imperfections, smooth out rough patches, and ensure a uniform surface. Follow this with a smoother grit sandpaper (e.g., 120 or 150 grit) for a finer finish. Ensure the entire surface is smooth and ready for staining. Thoroughly clean any sanding dust before proceeding.

Goal: Create a smooth, uniform surface for staining.

What's used

Tools

• Dust Mask
• Eye Protection
• Orbital Sander DeWalt
• Detail sander (for corners)
• Sandpaper (Rough Grit)
• Sandpaper (Smooth Grit)

About the full video

This DIY project details the process of transforming carpeted stairs into stylish, black-stained wooden stairs and railings. It involves removing old carpet, preparing the wood by stripping paint and sanding, installing new wood for the landing, and finally applying a black poly-stain for a modern contrasting look.

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.
