Before getting started, be sure that the joint surfaces of the top runway and ladder sections are

clean and dry. Unroll the gasket material and hold so that that length of the gasket is centered on
the center of the ladder joint. With the exposed adhesive side of the gasket facing the ladder joint
surface, apply the gasket starting at the center of the part, working outward to the sides. Be sure
that the bottom edge of the gasket material is held against the shelf on the ladder part during
installation, see reference images below. Do not make too tight of a bend radius with the gasket
when transitioning the gasket up the vertical edges of the joint. The transition radius should be as
large as possible. Making too tight of a bend radius will cause the gasket to kink and possibly
leak. The gasket should be centered on the available space in the vertical area of the joint, see
reference images below. Once the gasket is in place, firmly press down on the gasket in all
locations to ensure that the gasket has completely adhered to the ladder joint surface. Remove
the paper backing on the gasket to expose the adhesive. Use caution not to remove the
adhesive strip from the gasket when removing the paper backing.
