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 8B . A strip of caulking 10" long, should be placed along the horizontal seams.
Before bolting the next ring into 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
overlapping sheets. Additional 10" strips must be used to fill larger gaps that occur with heavier gauges
and laminated gauges. See
Page 27 for details on caulking of laminated sheets.
