Whether on the first floor or in the basement, many installations include a set of stairs.
In this tutorial, we demonstrate how to install an EnduraFlood wall panel system on stairs. While every set of stairs is different, the EnduraFlood system allows you to create a solution for nearly any installation challenge around stairs, even if they look different from the design used in this demonstration.
Depending on your specific staircase, adjustments may be required.

We will start on the inside of the stairs. Blocking has already been added between the studs, allowing us to securely staple trim pieces wherever needed.
The inside of the stairs can generally be built using one of two methods: the wraparound trim method or the flush trim method.
Both methods produce a clean, finished look, and the choice is up to the installer. For an EnduraFlood installation on the inside of stairs, only UNI-TRIM is required.

We begin at the top of the stairs using the wraparound trim method and work our way down, installing one piece of trim at a time.
For the second half of the stairs, we switch to the flush trim method. In addition to UNI-TRIM, thin wood spacers are used to fill the space beneath the tread nose.
Next, we create a cardboard template and test the fit by sliding it sideways into the trim configuration. Once confirmed, the template is transferred to the ENDURA-BOARD.

We are now ready to mount the panel. For the outside of the stairs, we use UNITRIM along with VERTI-COR/O.
Once again, we start at the top and work our way down.
Begin by mounting all of the UNI-TRIM. After cutting the ENDURA-BOARD to size, place it into position and support it using a BASE-KLIP.

Next, snap the pre-cut sections of VERTI-COR/O into place. As always, finish the installation by installing UNI-BASE.
Congratulations. You have now learned how to install EnduraFlood on both the inside and outside of stairs.
