Apply Adhesive and Install Treads

What happens in this clip

Before installing, apply construction adhesive to the back of each new vinyl stair tread. The video shows using DAP Multi-Purpose Adhesive, applying a bead around the perimeter and in a wavy pattern in the center for good adhesion. Then, carefully align and place the new tread over the existing stair, ensuring a tight fit against the stringers and riser. Use a rubber mallet to gently tap the tread into place and ensure it is fully seated. If necessary, a clamp can be used to slightly spread the stair stringers apart, making it easier to fit the tread without scraping.

Goal: Securely install the new vinyl stair treads

About the full video

This project details how to renovate a staircase by installing new vinyl stair treads over existing ones using DURASTAIR products. The process involves precise measurement and cutting of the vinyl treads, application of adhesive, and careful installation, followed by minor repairs and cleanup to achieve a refreshed look.

Step 6 of 8: 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.
