Install First Rounded Stair Tread

What happens in this clip

After installing the first riser, proceed to the first stair tread. Take a rounded stair tread (provided by the manufacturer for a seamless look) and carefully set it on the stair to ensure it fits tightly and evenly against the newly installed riser and the existing stair structure. Once the fit is confirmed, take measurements for the second, flat piece of vinyl that will complete the tread surface behind the rounded edge. Cut this second piece to fill the remaining gap. Before final installation, click the rounded tread and the flat piece together off the stair to ensure a secure connection. Apply the industrial adhesive to the back of the clicked-together tread assembly or directly to the stair (whichever method is preferred for ease of application). Carefully slide the complete tread assembly into place, ensuring it is even and tight against the riser below. A small gap at the very back of the tread is acceptable, as it will be covered by the next riser.

Goal: Install the first rounded stair tread and its corresponding flat piece

About the full video

This project provides step-by-step instructions for installing vinyl stair treads, including specialized rounded treads, to achieve a seamless and aesthetically pleasing staircase. The process covers preparing the stairs, applying adhesive, installing vertical risers and horizontal treads, and finishing with caulking.

Step 3 of 5: Install Peel-and-Stick Floor Protection

Measure and cut peel-and-stick vinyl tiles or protective sheets to fit each stair tread and the entry floor area. Carefully peel off the backing and apply the material smoothly, ensuring good adhesion and no air bubbles. Overlap edges slightly on stairs if using multiple pieces to create a continuous barrier. Trim any excess material for a clean finish.
