completely fills the head joint. After bedding the
brick, cut off the excess mortar and use it to start the
next end joint. Throw any surplus mortar back on the
mortar board where it can be restored to workability.
Figure 8-41 shows how to insert a brick into a
space left in a wall. First, spread a thick bed of mortar
(view 1), and then shove the brick into the wall space

(view 2) until mortar squeezes out of all four joints
(view 3). This way, you know that the joints are full
of mortar at every point.
To make a cross joint in a header course, spread
the bed joint mortar several brick widths in advance.
Then, spread mortar over the face of the header brick
before placing it in the wall (figure 8-42, view 1).
Next, shove the brick into place, squeezing out mortar
at the top of the joint.
Finally, cut off the excess
mortar as shown in view 2.
Figure 8-43 shows how to lay a closure brick in a
header course. First, spread about 1 inch of mortar on
the sides of the brick already in place (view 1), as well
