How to Install Carpet Treads on a Split-Level Staircase

For each stair tread, measure the width from the furthest point of the nosing on one side to the furthest point of the nosing on the other side. Then, measure the depth from the front edge of the tread (the nosing) to the riser. It is crucial to be precise as this will determine the size of your carpet treads. Record these measurements for each step, as stair dimensions can vary.

Using the measurements taken in the previous step, lay out your carpet. Mark the dimensions for each stair tread onto the carpet. Carefully cut each piece using a sharp utility knife or carpet shears, ensuring straight lines and accurate sizing. Account for any curves or angles specific to your staircase nosing.

Before applying the carpet treads, ensure that each stair tread is clean, dry, and free of dust, debris, and any residue from previous flooring or adhesives. Vacuum the stairs thoroughly and wipe down each tread with a damp cloth, allowing them to dry completely. This step is critical for a secure and long-lasting installation.

Depending on the type of carpet tread and adhesive you are using, apply a consistent layer of strong, carpet-appropriate adhesive. This could be a spray adhesive, a carpet tape, or a liquid adhesive applied with a trowel. Ensure full coverage to the edges for a secure bond. Follow the adhesive manufacturer's instructions regarding application method and drying/tack times.

Peel back the protective backing from the adhesive on the stair tread or the carpet tread (if using double-sided tape). Carefully align the carpet tread with the edge of the stair tread, starting from the back and working your way forward. Press down firmly, ensuring good contact and smoothing out any wrinkles or air bubbles. Pay special attention to securing the nosing.

After securing the carpet tread, inspect the edges. If there are any small areas where the carpet slightly overhangs or has frayed edges, carefully trim them with a sharp utility knife to create a neat and professional finish. This is typically only needed for minor imperfections.
