sill sections together while inserting FM10 splice and threading the WC19 gasket into the adjoining gasket reglet. Anchor starter sills.
20. Apply sealant into the joint between the sections of starter sill and tool to create a water tight seal. The splice joint width will vary per project
requirements. See Figure 15. Seal the ends of the WC19 gaskets and butt them together.
