| Considerations | Keep timber framing dry. Framing can have a maximum moisture content of no more than 18% to apply the stonework. As such we recommend using Kiln dried timber (14%-16% moisture) and wrapping the building asap. SUMNER Board acts as a rain shield so this should also be put in place asap. | |||||||||
