Apply Adhesive to Treads

What happens in this clip

After cutting a stair tread to its final size, flip it over to expose its underside. Apply a generous amount of strong construction adhesive or specialized carpet adhesive to the back of the tread. Distribute the adhesive evenly, focusing on applying a continuous bead around the perimeter and adding a few wavy beads or dots in the center. This ensures maximum adhesion across the entire surface and helps prevent future lifting.

Goal: Securely bond the treads to the stair steps

What's used

Tools

• Caulk gun
• Construction adhesive
• Liquid Nails
• Stair treads

About the full video

This project provides a step-by-step guide on how to install pre-made stair treads onto a wooden staircase. The process involves precise measurement and dry-fitting, cutting the treads to size, applying adhesive for secure bonding, and finally, fastening the treads with a staple gun to ensure a durable and aesthetically pleasing finish.

Step 5 of 8: Apply Adhesive

Depending on the adhesive used (e.g., spray adhesive, carpet tape, construction adhesive), apply it according to its specific instructions. For spray adhesives, apply a light, even coat to the back of the carpet tread or the stair surface. For carpet tape, apply strips along the edges and potentially the center of the tread. For construction adhesive, use a caulk gun to apply beads. Ensure full coverage, especially along the edges, to prevent lifting.
