J. Continue inserting spacers and blocks in this manner to complete
the row. Do not apply sealant to the side of the last block and last
spacer. Insert the last block in the side channel and slide it into
the bottom channel.
N. Remove any excess sealant. If necessary, adjust the size of the
sealant beads to prevent squeeze out on the following rows. The
joint areas must be kept clean of sealant.
M. Place a horizontal spacer on top of the first row of blocks. If more
than one section of horizontal spacer is required, be sure to lay
them end to end with the joint directly above vertical spacer.
Stagger these joints on each following row.
L. Apply two 1/4” beads of sealant to the top of the row of blocks just
behind the raised edges.
K. Check the first row for alignment of spacers and blocks. Make
sure all the blocks are sitting completely in the channel and
the joints are tight.
