manufacturer’s preparation and application instructions should be followed exactly. If sealant primer is required, apply it per the primer/sealant
manufacturer’s instructions.
9. Apply a generous amount of sealant to the jamb end of the starter sill. See Figure 28.
10. Plug the ends of the dynamic starter sill gutter at jamb and corner conditions by recessing backer rod at least 1/4” into the end of the front part of the gutter.
Apply sealant to fill the void at the ends and tool the sealant flush. See Figures 28 and 29. Intermediate splice locations incorporate an internal splice sleeve
and will be covered later in this section.
11. When setting the starter sill gutter onto the gutter base, align the race ways on the bottom of the gutter with WC16 gasket in the gutter base. See Figure 32.
12. Attach the gutter to the gutter base with SPZ1 fasteners to secure it in place. See Figure 30.
13. Immediately tool the sealant at the end dam to gutter joint. Apply additional sealant as necessary to seal all around the end of the gutter as shown. The
sealant must be thoroughly tooled at this joint to create a water tight seal. See Figures 31 and 32.
