made. Make sure this point is high enough to ensure that the bottom edge of the
siding is installed at least 6” above the finished grade or 1” above surfaces where
water may collect.
2. From this mark, snap a level chalk line to the opposite end of the wall.
3. Repeat the procedure around the entire house.

NOTE: When installing Allura Fiber Cement Siding into a J-channel or other receiving
channel, ensure that all cut edges have been re-sealed with primer or paint prior to
insertion; do not caulk between the siding and the channel, either before or after
siding installation as this may restrict water movement around the opening. Make sure
all corners are properly flashed.
