3.3
INSTALLATION
A.
Install in accordance with manufacturer's instructions.
B.
Install products from a single manufacturer as specified above based on adjacent construction and substrates.
C.
Coursing and Bond Patterns:
1.
Establish lines, levels, coursing and bond patterns indicated. Protect from displacement.
2.
Maintain masonry courses to uniform dimensions. Form vertical and horizontal joints of uniform thickness.
3.
Refer to the Drawings for special details and treatments at corners, openings, and transitions. Maintain architectural alignments as indicated.
D.
Mortar Mixing:
1.
Mix mortar only in quantities needed for immediate use.
2.
Measure materials by volume or equivalent weight, using the same measurement for each material and batch. Do not measure by shovel.
3.
If mortar color is to be used, add in accordance with manufacturers recommendations. Ensure uniformity of mix and coloration.
4.
Clean mixing boards and mechanical mixing machine between batches.
E.
Mortar Joints:
1.
3/8 inch (9.5 mm) thick unless otherwise indicated.
F.

After tooling mortar, cut off mortar tailings with a trowel and brush mortar burrs and dust from the face of the brick.
G.
After laying each brick, cut off the excess mortar with a forward lifting and rolling motion of the trowel to collect mortar and prevent smearing back onto the brick face. Do not cut mortar so surplus drops to the face of the wall.
H.
Tuck Pointing:
1.
If required, and only where recommended by BIA Technical Note 11B - "Guide Specification for Brick Masonry", rake mortar joints to a depth of not less than 1/2 inch (12.7 mm) nor more than 3/4 inch (19 mm).
