Step 4 · Apply Adhesive to Stair Treads
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.
