About the full video

This DIY project details the complete transformation of an old, carpeted staircase into a modern, visually appealing set of stairs with laminate treads and painted risers. The process involves removing old carpet, prepping the stairs, painting, modifying existing treads, installing new laminate, and reinstalling a painted railing.

Step 9 of 11: Fill Nail Holes and Gaps

Using a putty knife, apply wood filler to any nail holes, screw holes, or small gaps in the hardwood treads and risers. Press the filler firmly into the voids. Smooth the excess filler flush with the wood surface using the putty knife. Allow the wood filler to dry completely according to the manufacturer's instructions.
