PART G - LAYING CONCRETE BLOCKS BETWEEN CORNERS
To ensure a good bond, do not spread mortar too far ahead of the actual laying of the block. When
mortar is allowed to sit, it will stiffen and lose its plasticity. As each block is laid, cut off excess mortar
with your trowel and work it back into the fresh mortar (Figure 2-16).

2-18. Using a Mason's Line. As you fill in the wall between the corners, stretch a mason's line from
corner to corner for each course. Lay the top outside edge of each block to his line. Tip the block
slightly toward you so you can see the edge of the course below, making sure that the lower edge of the
block is directly over the course below (Figure 2-17, page 2-20).
