A. Wetting Brick:
Guide Specification
1: Wet brick with absorption rates in excess of 20 g./30 sq. in./min. (20 g./194 cm²/min.) determined by ASTM C 67, so that rate of absorption when laid does not exceed this amount.
2. Recommended procedure to insure that brick are nearly saturated, surface dry when laid is to play a hose on the pile of brick until the water runs from the pile. This should be done one day before brick are to be used. In extremely warm weather, play hose on pile several hours before brick are to be used.

1. Where fresh masonry joins partially set masonry:
a. Remove loose brick and mortar.
b. Clean and lightly wet exposed surface of set masonry.
2. Stop off horizontal run of masonry by racking back 1/2 length of unit in each course.
3. Toothing is not permitted except upon written acceptance of the Architect/Engineer.
C. Tooling and Tuck Pointing:
1. Tooling:
a. Tool exposed joints when "thumb-print" hard with a round jointer, slightly larger than width of joint.
