What happens in this clip
After preparing the riser, move on to the corresponding stair tread. Measure the depth and length of the tread. Similar to the riser, use your cutting saw to cut the tread material 1/8 inch shorter than the measured depth and 1/8 inch shorter than the measured length. These precise, slightly short cuts allow for the necessary expansion gaps and space for caulking.
Goal: Prepare the first tread for installation

About the full video
This project provides step-by-step instructions for properly installing performance accessory stair treads and risers. It covers preparation, precise measuring and cutting, adhesive application, securing with a finish nailer, caulking expansion gaps, and installing optional return trim for exposed stair sides. The guide emphasizes the importance of specific adhesive types and proper expansion gaps for a durable and aesthetically pleasing finish.
Step 2 of 6: Measure Tread Depth
For each step, use a tape measure to determine the tread depth. Place the tape measure at the very front edge of the tread and extend it horizontally to where the tread meets the riser. Record this measurement for every step. It's common for tread depths to vary slightly, so note each individual measurement.
