21. Using an approved solvent or cleaner, clean the sealant contact surfaces of the starter sill of all oils and other contaminants where the splice will
be applied. The sealant manufacturer’s preparation and application instructions should be followed exactly. If sealant primer is required, apply it
per the primer/sealant manufacturer’s instructions.
22. Apply a bed of sealant on the starter sill gutter that will cover the entire area where gutter splice (HC08 or HC09) will be applied. The sealant must go from
the reveal up the engagement leg to the WC19 gasket track. See Figures 35 and 37.
23. Lay the gutter splice into the bed of sealant. Slide the gutter splice up under the WC19 gasket track. See Figure 37. Smooth the splice down onto the
gutter, forcing out all air bubbles.
24. Apply sealant around the perimeter of the gutter splice. Tool the sealant to ensure a watertight seal at the splice. See Figure 36.
