more than 18 inches (457 mm) on center for Standard Series, every other course for Thinline Series. Panel anchors if used shall be installed in the same joints as reinforcing.

3.3.1.6 Isolate panel from adjacent construction on sides and top with expansion strips. Keep expansion joint voids clear of mortar.

3.3.1.7 Maintain uniform joint width of 1/4 in (6 mm) plus or minus 1/8 in (3 mm).3.3.1.8 Maximum variation from plane of unit to next unit to be 1/32 in (0.8 mm).3.3.1.9 Maximum variation of panel from plane to be 1/16 in (1.5 mm).3.3.1.10 Do not use retempered mortar.3.3.1.11 Do not tap glass block with steel tools.3.3.1.12 When mortar has set, pack backer rod in jamb and head channels. Recess to

allow for sealant.3.3.1.13 Apply sealant as required.

3.4 CLEANING

3.4.1 Remove excess mortar from glass surfaces with a damp cloth before set occurs.

3.4.2 Strike and tool joints as required for proper sealing/

3.4.3 Number 4 (0000) steel wool can be used to remove remaining mortar and dried film.

3.5 PROTECTION

3.5.1 Protect installed products until completion of project.3.5.1.1 Protect top of wall until covered or capped to a waterproof condition by

subsequent construction.3.5.1.2 Prevent grout, mortar, and soil from staining the face of masonry to be left

exposed. Remove immediately any grout, mortar, and soil that comes in contact with such masonry.

3.5.1.3 Protect base of walls from rain-splashed mud and mortar splatter by means of coverings spread on ground and over wall surface.

3.5.1.4 Protect sills, ledges, and projection from mortar splatter and dropping.3.5.1.5 Protect surfaces of windows and door frames; as well as similar products with

painted and integral finishes from mortar splatter and dropping.

3.5.2 Touch-up, repair or replace damaged products before Substantial Completion.
