1. Before proceeding with the glazing process, a thorough cleaning of the exposed areas of the shadow box must be done.
2. Blow all debris out of the joints around the edges and exposed areas of the shadow box. Any metal shavings or dirt must be removed from the opening.
After the unit is glazed, during handling, debris could dislodge and become visible through the glass unless proper cleaning is performed.
3. Use isopropyl alcohol to clean the exposed finished surfaces of all smudges, finger prints, and sealant. Once the unit is glazed, these areas will be
inaccessible, so a thorough cleaning is essential.
4. Proceed to Volume 2, Section 4 “Unit Glazing Preparation”.
