How to Apply Stair Treads

Adding treads to your existing stairs can make them safer and easier to negotiate. Those stair treads provide a firm surface and make gripping the stairs easier and safer. The key to installing new treads on your stairs is to measure them carefully. The treads themselves are typically oversized, and you must cut them to the appropriate size before applying them to your existing set of stairs.

      Prepare the steps by cleaning them thoroughly. The stairs must be clean, dry and free of grease, old paint and contaminants. The stair treads will not adhere properly if the stairs are not properly prepared. Also fill in any cracks or holes in the stairs before you begin the installation.

      Cut the stair treads to fit the length and width of each step. The treads must be properly sized to fit each step.

      Spread the adhesive all the way across the stair step. Be sure to cover the entire surface of the step before applying the stair tread. Place the adhesive on two steps at a time, and install the two stair treads.

      Set the stair tread in place, starting at the front of the step and pressing the tread into place. Press firmly to ensure there are no air bubbles between the stair and the tread. Roll a hand roller over the tread after it has been installed to seal it and press it firmly into place.
