from Project site and legally dispose of off Project site. Damaged glass is glass with edge
damage or other imperfections that, when installed, could weaken glass and impair
performance and appearance.
D. Apply primers to joint surfaces where required for adhesion of sealants, as determined by
preconstruction testing.
E. Install setting blocks in sill rabbets, sized and located to comply with referenced glazing

specified.
3.4 TAPE GLAZING
A. Position tapes on fixed stops so that, when compressed by glass, their exposed edges are flush
with or protrude slightly above sightline of stops.
B. Install tapes continuously, but not necessarily in one continuous length. Do not stretch tapes to
make them fit opening.

press firmly against soft compression gasket by inserting dense compression gaskets formed
and installed to lock in place against faces of removable stops. Start gasket applications at
corners and work toward centers of openings.
D. Install gaskets so they protrude past face of glazing stops.
3.6 SEALANT GLAZING (WET)
A. Install continuous spacers, or spacers combined with cylindrical sealant backing, between glass
lites and glazing stops to maintain glass face clearances. Secure spacers or spacers and
backings in place and in position to control depth of installed sealant relative to edge clearance
for optimum sealant performance.
B. Force sealants into glazing channels to eliminate voids and to ensure complete wetting or bond
of sealant to glass and channel surfaces.
C. Tool exposed surfaces of sealants to provide a substantial washaway from glass.
3.7 CLEANING AND PROTECTION
A. Immediately after installation, remove nonpermanent labels and clean surfaces.
B. Protect glass from contact with contaminating substances resulting from construction
