Do not use sand-cement mortar for
courses other than the leveling course.
Step 1
-Mix thin-bed mortar.
Mix thin-bed mortar.
Before mixing new batch, wash out the bucket or pail to prevent any old thin-bed from accelerating the drying time of the new mix.
Step 2
-Clean bed joint surface.
With a brush, sweep off all dust and
loose particles to insure adhesion of the thin-bed mortar.
Step 3
- Apply thin-bedmortar to head and bed joints.
Using a clean, notched trowel the same width as the block spread thin-bed
mortar up the head joint of the adjoining block and then along the bed joint.
Spread only enough thin-bed mortar to lay one block at a time. The thin-bed
mortar must cover the full width of the joints. Install block in a running bond
with a minimum 4" bearing (overlap) or 40% of the block's height (whichever is greater).
