How to Paint Oak Stair Railings (DIY Staircase Banister Makeover)

Moments in this video

1. 0:56–1:55 Sand All Exposed Surfaces From Stair Banister Refinishing, Step 2: Lightly Sand the Surface

   Begin by thoroughly sanding all exposed wooden surfaces of the stairwell, including the handrails, newel posts, and balusters. The goal is not to remove all of the existing finish, but rather to 'scuff' it using a fine grit sandpaper. This creates a surface that the primer can properly adhere to. The video creator used a sanding block, emphasizing the utility of a V-shaped sanding block for getting into the various nooks and crannies of the balusters and posts. This process can be time-intensive, taking a couple of hours for the entire stairwell.

2. 2:13–3:04 Apply Primer Coat From Stair Banister Refinishing, Step 3: Apply Bonding Primer (if painting)

   Apply a preliminary coat of primer to all the prepped and taped stairwell surfaces. The video recommends using a short brush exclusively, as many railings have rounded or intricate shapes where a roller might not provide a consistent finish. The first coat of primer may appear blotchy and see-through, which is normal. The subsequent paint coats will provide full coverage. Allow adequate drying time as per the primer manufacturer's instructions before proceeding.
