Racking
:
The most common area of cracking is along the horizontal cement board/drywall
transition; placing this transition further away from the heat will help prevent cracks. If you
have concerns of excessive finishing wall temperature follow one of these options to mini
-
mize the possibility of cracking:
1. Install the optional heat distribution kit (50-3455 or 50-3713).
2. Install concrete board higher than the minimum specified dimension.
3. Add a decorative tile trim over the drywall transition area.
