Step 6 · Apply Adhesive and Fasten Treads

Apply a generous bead of high-quality construction adhesive along the top surface of the existing stair substrate, ensuring full coverage. Carefully place the new tread onto the adhesive. For added security, fasten the tread from the top using wood screws. Predrill pilot holes to prevent splitting the wood, and countersink the screw heads so they can be filled later. If you have access from below, you can also use screws driven upwards into the tread, or specialized angle brackets.
