Apply one strip of caulking near the outside edge of the outer sheet and between the outer two (2) rows
of bolts, refer to
Figure 8C . A strip of caulking 10" long, should be placed along the horizontal seams.
Before bolting the next ring in place, apply one strip of caulking 10" long on the front of the underlapped
sheet at each joint. Also, a 10" strip of caulking is to be placed along the lower horizontal edge of lapping
sheet at every vertical seam. This will fill the space that occurs between the holes caused by the
overlapped sheets. Additional 10" strips should be used to fill gaps that occur with heavier gauges.
