Step 1 · Step 1: Prep Your Treads for a Flawless Finish

Start by wiping down each oak stair tread with a tack cloth to remove any lingering dust or debris. Next, give each tread a light sanding with 220-grit sandpaper. This step doesn't just smooth the wood; it also helps the polyurethane finish adhere properly for a long-lasting, durable coat. Once you're done sanding, use a fresh tack cloth to wipe away every last bit of dust.
