When bolting the two (2) assembled/laminated sheets to each other, apply one strip of caulking near the
outside edge of the outer sheet, between the outer two (2) rows of bolts and outside the last row of bolts.
(See Figure 8D.) A strip of caulking 12" long should be placed along the horizontal seams. Before bolting
the next ring into place, apply one strip of caulking 12" long on the front of the under lapped sheet at each
joint. Also, a 12" strip of caulking is to be placed along the lower horizontal edge of the lapping sheet at
the vertical seam. This will fill the space that occurs between the holes caused by the overlapping sheets.
Additional 12" strips must be used to fill larger gaps that may occur with thicker gauges.
When assembling two (2) sheets to make a laminated sheet assembly, apply a row of caulk all around the
vertical seam. See
Figure 8D for details.
