Use the following steps to apply Dow 995 structural silicone sealant:
Step 1: Clean
Clean all joints and glazing pockets, removing all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants, or glazing compounds and protective coatings.
Step 2: Apply Sealant
Install back-up material or joint filler, setting blocks, spacer shims, and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required on non-porous surfaces, but may be necessary for optimal sealing of certain porous surfaces. A test placement is always recommended.
Apply Dow 995 Silicone Structural Glazing Sealant in a continuous operation using a positive pressure. The sealant can be applied using many types of air-operated guns and most types of bulk dispensing equipment. Within 10 minutes of opening up the cartridge, tool the sealant with light pressure to spread the sealant against the backing material and joint surfaces. Remove masking tape as soon as the bead is tooled.
