2.13 Check with a level to confirm that the wall is straight, level and plumb as you build. Use a level to check the alignment of the course of glass blocks.
After installing four or five courses of glass blocks, you may want to start on the curve wall. This will allow the sealant to set. Always apply sealant to the glass
blocks not on the installed horizontal spacers. Check the alignment of the glass blocks vertically and horizontally as you build.

inch beads of sealant to the
second row of blocks behind the raised edge of the glass block face on both sides of the blocks. Install this course of glass blocks the same as the first course.
IMPORTANT: After completing the second course of glass blocks check the horizontal and vertical joints for sealant. If there is sealant in the joints you need
to use a smaller bead or dab of sealant or slightly move the location of the bead of sealant behind the raised edge of the glass block face toward the center
of the block.
