e. Apply temporary retainers at verticals. Temporary retainers will be comprised of FM38, 4” pieces of 17T2 and WC22 gasket. If there is captured
glazed system on the job used scraps for this. If there is none available then the materials for these temporary retainers must be ordered.
g. Tool the sealant around the perimeter of the glazing, packing the sealant into the joint, to ensure any voids or air bubbles in the sealant are
eliminated.
h. Once the structural silicone cures remove the temporary glazing retainers, and replace with LC45 with cover.
i.
Do not apply the weather seal around the perimeter of the glazing until the structural silicone joint cures. The SSG joint will typically take 7-14 days,
but it can take up to 28 days to fully cure depending on temperature and humidity. Consultation with the sealant manufacturer is recommended.
j. When the structural silicone joints are fully cured, remove the temporary retainers. Properly clean and prepare the joints, apply backer rod and the
weather seal. Tool the joint to form an hour glass shaped sealant joint as shown.
