34. Using an approved solvent or cleaner, clean the sealant contact surfaces of the starter sill of all oils and other contaminants where the silicone
splice sleeve 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.
35. Apply silicone sealant from the top, down the front and on the bottom of the reveal splice to fill the joint. Sealant should fill the void completely and must be
tooled flush all around, including the underside of the starter sill. See Figure 40.
36. Remove excess sealant to form a neat caulk joint in the exposed areas.
37. 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 41 and 42.
38. Lay the gutter splice into the bed of sealant. Slide the gutter splice up under the WC19 gasket track. See Figure 42. Smooth the splice down onto the
gutter, forcing out all air bubbles.
39. Apply sealant around the perimeter of the gutter splice. Tool the sealant to ensure a watertight seal at the splice. See Figure 43.
40. Apply sealant in the gap between the two starter sills from the WC19 gasket, across the top of the engagement leg and down the back leg. Tool the sealant
into all voids to ensure a watertight seal. See Figure 42.
