2. When re-glazing an opening or openings at a structural silicone glazed, follow these instructions:
a. Using an approved solvent or cleaner, clean the glazing surfaces of all oils and other contaminants. The sealant manufacturer’s
preparation and application instructions should be followed exactly. Fresh sealant will adhere to cured sealant without primer. Primer may be
necessary if the sealant has been completely removed.
b. Replace WC18 preset spacer gasket with new gasket around the entire opening. Ensure the gaskets are firmly butted together in the corners.
c. Run a bead of sealant around the WC18 gasket as shown below. The joint must be filled with sealant in excess so that it will fill all voids between the
glazing and the WC18 gasket when the glazing is put in place. Tool the sealant into a beveled shape as shown below prior to setting the glazing.
Ensure no voids or air bubbles are present in the sealant. The glazing must be set within 10 minutes or before the sealant begins to skin over.
Apply new WC18
spacer gaskets.

Only silicone sealants which have been
developed and tested specifically for
structural glazing applications should
be used for re-glazing purposes.
